Until recently, psychologists have conceptualised and studied trust in God (TIG) largely in isolation from contemporary work in theology, philosophy, history, and biblical studies that has examined the topic with increasing clarity. In this article, we first review the primary ways that psychologists have conceptualised and measured TIG. Then, we draw on conceptualizations of TIG outside the psychology of religion to provide a conceptual map for how TIG might be related to theorised predictors and outcomes. Finally, we provide a research (...) agenda for future empirical work in this area, as well as practical applications for counsellors and religious leaders. (shrink)

"He who is satisfied has never truly craved. And he who craves for the light of God neglects his ease for ardor." -Rabbi Abraham J. Heschel.

We motivate a picture of social epistemology that sees forgetting as subject to epistemic evaluation. Using computer simulations of a simple agent-based model, we show that how agents forget can have as large an impact on group epistemic outcomes as how they share information. But, how we forget, unlike how we form beliefs, isn’t typically taken to be the sort of thing that can be epistemically rational or justified. We consider what we take to be the most promising argument for (...) this claim and find it lacking. We conclude that understanding how agents forget should be as central to social epistemology as understanding how agents form beliefs and share information with others. (shrink)

I argue that humans have moral relationships with dogs and cats that they could adopt, but do not. The obligations of those of us who refrain from incurring particular relationships with dogs and cats are correlative with the power of persons with what Jean Harvey calls “interactive power,” the power to take the initiative in and direct the course of a relationship. I connect Harvey’s points about interactive power to my application of Eva Kittay’s “dependency critique,” to show that those (...) of us who refrain from incurring particular relationships of dependency rely on caregivers in our communities and regions to fulfill the moral and social demands that an abundance of unowned companionable animals makes on the community.

What considerations place genuine constraints on an adequate semantics for normative and evaluative expressions? Linguists recognize facts about ordinary uses of such expressions and competent speakers’ judgments about which uses are appropriate. The contemporary literature reflects the widespread assumption that linguists don’t rely upon an additional source of data—competent speakers’ judgments about possible disagreement with hypothetical speech communities. We have several good reasons to think that such judgments are not probative for semantic theorizing. Therefore, we should accord these judgments no (...) probative value for the development of a semantics for our moral terms. Such judgments can no longer be presumed to put pressure on theories according to which our moral expressions share a semantics with ordinary, descriptive terms. Many rivals to pure, Descriptivist theories count among their advantages the ability to accommodate these judgments. If these judgments have no probative value, such theories lose an important source of support. (shrink)

This is the introduction to a special issue of AAPT Studies in Pedagogy on Teaching Plato. I open by noting that the philosophy of education was of central concern to Plato in a way that you don't often see with philosophers. Only Confucius and John Dewey do as much to make education central to everything else they say. I also note that much subsequent philosophy of education merely rediscovers what Plato already knew. After that, I preview the contents of the (...) volume, emphasizing the ways in which contributors ask us to teach Plato platonically. (shrink)

This paper makes an effort to interpret the relationship between the concepts "Zuhandenheit" (readiness-to-hand) and "Vorhandenheit" (presence-at-hand), as they are analysed in §§ 15-16 of Heidegger's "Being and Time". These concepts are two modes of existence of the beings met in our surrounding world. So, they don't concern different things. Heidegger doesn't give the title "things" to the beings ready-to-hand; he names them "equipments" (Zeug). It's a concept relative to the Aristotelian "organon", which Aristotle exemplifies with the human hand as (...) a primary equipment. But Zuhandenheit isn't a quality of the things; the term has to do with the secret character of the equipments as the maining way of their disclosure. It's the Being-in-itself of the equipments, as long as they are useful. This Being-in-itself has nothing common with the Kantian Ding an sich, which is based on the presupposition of a cognitive relationship between subject and object. I posit also the question, whether Zuhandenheit can rendet the secretness and familiarity of our immediate approach to the environment, and my answer to this question is negative. (shrink)

1. First there is an outline of the libertarian approach taken here. 2. On the assumption of personhood, it is explained how there need be no overall inflicted harm and no proactive killing with abortion and infanticide. This starts with an attached-adult analogy and transitions to dealing directly with the issues. Various well-known criticisms are answered throughout. 3. There is then a more-abstract explanation of how it is paradoxical to assume a duty to do more than avoid inflicting overall harm (...) and, instead, positively benefit. A putative counterexample is explained away. 4. A positive theory of intellectual personhood is defended in principle, but not made precise, which is sufficient to be practical. The greater moral value of intellectual-personhood is defended. An important putative reductio of the potential-personhood argument is refuted. 5. Several further criticisms that apply to both types of defences are answered. 6. Conclusion. (shrink)

This essay explains various significant errors, imprecisions, and omissions concerning libertarianism in Long 2013. The “right not to be aggressed against” is not, as such, the libertarian right because the ‘right to liberty’ must be that right (although not being aggressed against can charitably be interpreted as equivalent). There are non-libertarian rights, but they don’t override the right to liberty. Unsupported assumptions are inevitable because justifications are impossible. Rights should not be “defined” but, rather, morally and metaphysically theorised—with criticism permanently (...) invited. Moral and legal permissibility need to be clearly distinguished. The conceptions of “aggression” and “force” are normative and confused. It is possible to advocate the right to liberty on no grounds whatsoever and also to conjecture that liberty (deontologically) and welfare (consequentially) are systematically compatible in practice for theoretical and causal reasons. The rejection of positive rights is “privileging” and not “conceptual”. Libertarian property needs to be derived from an explicit, non-normative, theory of libertarian liberty. Long 2013’s overall account is “mysterious” and “one-sided”. (shrink)

"No, your honor. I didn't know who or what he was when I first came across the book -- they don't exactly love him in the synagogue, if you've read the story of his life. I found it in a junkyard in a nearby town, paid a kopek, and left cursing myself for wasting money hard to come by. Later I read through a few pages and kept on going as though there were a whirlwind at my back. As I (...) say, I didn't understand every word but when you're dealing with such ideas you feel as though you were taking a witch's ride. After that I wasn't the same man. That's in a manner of speaking, of course, because I've changed little since my youth.". The speaker is Yakov Bok, the unlikely hero of Bernard Malamud's The Fixer. At this point, early in the novel, Yakov speaks truthfully when he says that he has changed little since his youth. But over the next two and a half years (the time-period covered in the novel), he will undergo profound change and impressive moral growth. He suffers; he learns; he grows. Spinoza's name and ideas appear again and again at crucial moments in the course of the hero's moral development. Yakov Bok's verbal account of Spinoza's ideas is often comically primitive, but his understanding far outstrips his ability to articulate. By the end of the novel, his sufferings have led him to a deep grasp of certain of Spinoza's ethical and political doctrines. (shrink)

You don’t know that p unless it’s on account of your cognitive abilities that you believe truly that p. Virtue epistemologists think there’s some such ability constraint on knowledge. This looks to be in considerable tension, though, with putative faith- based knowledge. For it can easily seem that when you believe something truly on the basis of faith this isn't because of anything you're competent to do. Rather faith-based beliefs are a product of divine agency. Appearances notwithstanding, I argue in (...) this paper that there’s no deep tension between faith-based knowledge and virtue epistemology. Not if we learn to conceive of faith as a kind of extended knowledge. (shrink)

Evidential Uniqueness is the thesis that, for any batch of evidence, there’s a unique doxastic state that a subject with that evidence should have. One of the most common kinds of objections to views that violate Evidential Uniqueness are arbitrariness objections – objections to the effect that views that don’t satisfy Evidential Uniqueness lead to unacceptable arbitrariness. The goal of this paper is to examine a variety of arbitrariness objections that have appeared in the literature, and to assess the extent (...) to which these objections bolster the case for Evidential Uniqueness. After examining a number of different arbitrariness objections, I’ll conclude that, by and large, these objections do little to bolster the case for Evidential Uniqueness. (shrink)

Sometimes ignorance is a legitimate excuse for morally wrong behavior, and sometimes it isn’t. If someone has secretly replaced my sugar with arsenic, then I’m blameless for putting arsenic in your tea. But if I put arsenic in your tea because I keep arsenic and sugar jars on the same shelf and don’t label them, then I’m plausibly blameworthy for poisoning you. Why is my ignorance in the first case a legitimate excuse, but my ignorance in the second case isn’t? (...) This essay explores the relationship between ignorance and blameworthiness. (shrink)

Standard Analytic Epistemology (SAE) names a contingently clustered class of methods and theses that have dominated English-speaking epistemology for about the past half-century. The major contemporary theories of SAE include versions of foundationalism, coherentism, reliabilism, and contextualism. While proponents of SAE don’t agree about how to define naturalized epistemology, most agree that a thoroughgoing naturalism in epistemology can’t work. For the purposes of this paper, we will suppose that a naturalistic theory of epistemology takes as its core, as its starting-point, (...) an empirical theory. The standard argument against naturalistic approaches to epistemology is that empirical theories are essentially descriptive, while epistemology is essentially prescriptive, and a descriptive theory cannot yield normative, evaluative prescriptions. In short, naturalistic theories cannot overcome the is-ought divide. Our main goal in this paper is to show that the standard argument against naturalized epistemology has it almost exactly backwards. (shrink)

I apply the notion of truthmaking to the topic of fundamentality by articulating a truthmaker theory of fundamentality according to which some truths are truth-grounded in certain entities while the ones that don't stand in a metaphysical-semantic relation to the truths that do. I motivate this view by critically discussing two problems with Ross Cameron's truthmaker theory of fundamentality. I then defend this view against Theodore Sider's objection that the truthmaking approach to fundamentality violates the purity constraint. Truthmaker theorists can (...) have a trouble-free theory of fundamentality. (shrink)

My main aim in this paper is to improve and give further support to a defense of the Principle of Alternative Possibilities (PAP) against Frankfurt cases which I put forward in some previous work. In the present paper I concentrate on a recent Frankfurt case, Pereboom's "Tax Evasion". After presenting the essentials of my defense of PAP and applying it to this case, I go on to consider several objections that have been (or might be) raised against it and argue (...) that they don't succeed. I conclude by pointing out that my criticism of Pereboom's example suggests a general strategy against other actual or possible Frankfurt cases. (shrink)

Contextual vocabulary acquisition (CVA) is the deliberate acquisition of a meaning for a word in a text by reasoning from context, where “context” includes: (1) the reader’s “internalization” of the surrounding text, i.e., the reader’s “mental model” of the word’s “textual context” (hereafter, “co-text” [3]) integrated with (2) the reader’s prior knowledge (PK), but it excludes (3) external sources such as dictionaries or people. CVA is what you do when you come across an unfamiliar word in your reading, realize that (...) you don’t know what it means, decide that you need to know what it means in order to understand the passage, but there is no one around to ask, and it is not in the dictionary (or you are too lazy to look it up). In such a case, you can try to figure out its meaning “from context”, i.e., from clues in the co-text together with your prior knowledge. Our computational theory of CVA—implemented in a the SNePS knowledge representation and reasoning system [28]—begins with a stored knowledge base containing SNePS representations of relevant PK, inputs SNePS representations of a passage containing an unfamiliar word, and draws inferences from these two (integrated) information sources. When asked to define the word, definition algorithms deductively search the resulting network for information of the sort that might be found in a dictionary definition, outputting a definition frame whose slots are the kinds of features that a definition might contain (e.g., class membership, properties, actions, spatio-temporal information, etc.) and whose slot-fillers contain information gleaned from the network [6–8,20,23,24]. We are investigating ways to make our system more robust, to embed it in a naturallanguage-processing system, and to incorporate morphological information. Our research group, including reading educators, is also applying our methods to the develop-. (shrink)

A number of philosophers have argued that if you care about how much goodness your actions generate, or how good the state-of-affairs you actions bring about are, then your attention should be directed towards the very far future. But many don’t care about how much goodness their actions generate, nor do they care about things like “states-of-affairs”. Amongst a multitude of things, many people care about how their actions impact individuals. And they also care about the sorts of justifications they (...) are able to offer for those actions. One moral theory which captures this moral viewpoint is contractualism. In this chapter, I argue that contractualism is, in large part, incompatible with longtermism – the view that, in many contexts, we ought to do that which will most improve the prospects of future people. I then discuss what advice, if any at all, contractualism can offer to the longtermist. (shrink)

In this book Alan Haworth tends to sneer at libertarians. However, there are, I believe, a few sound criticisms. I have always held similar opinions of Murray Rothbard‟s and Friedrich Hayek‟s definitions of liberty and coercion, Robert Nozick‟s account of natural rights, and Hayek‟s spontaneous-order arguments. I urge believers of these positions to read Haworth. But I don‟t personally know many libertarians who believe them (or who regard Hayek as a libertarian).

In [1] it is claimed that, based on radiation emission measurements described in [2], a certain “variant” of the Orch OR theory has been refuted. I agree with this claim. However, the significance of this result for Orch OR per se is unclear. After all, the refuted “variant” was never advocated by anyone, and it contradicts the views of Hameroff and Penrose (hereafter: HP) who invented Orch OR [3]. My aim is to get clear on this situation. I argue that (...) it is indeed reasonable to speak of “variants” here. Orch OR is not a complete model of reality but a work in progress. At its core, it claims that wavefunction collapse is a real physical event that has something to do with gravity (“OR”) and that consciousness depends on orchestrated collapses in microtubules (“Orch”). There are many ways one could make these base ideas precise hence many “variants”. Furthermore, the ways that HP aim to make these ideas precise are radical and incomplete. If they don’t work out, Orch OR will need to fall back on another variant. Thus, I believe the significance of [1-2] for Orch OR is that it cuts out a small class of possible variants and leaves behind questions and challenges for the rest, including the variant preferred by HP.

Hauser argues that his pocket calculator (Cal) has certain arithmetical abilities: it seems Cal calculates. That calculating is thinking seems equally untendentious. Yet these two claims together provide premises for a seemingly valid syllogism whose conclusion - Cal thinks - most would deny. He considers several ways to avoid this conclusion, and finds them mostly wanting. Either we ourselves can't be said to think or calculate if our calculation-like performances are judged by the standards proposed to rule out Cal; or (...) the standards- e.g., autonomy and self-consciousness- make it impossible to verify whether anything or anyone (save oneself) meets them. While appeals to the intentionality of thought or the unity of minds provide more credible lines of resistance, available accounts of intentionality and mental unity are insufficiently clear and warranted to provide very substantial arguments against Cal's title to be called a thinking thing. Indeed, considerations favoring granting that title are more formidable than is generally appreciated. Rapaport's comments suggest that, on a strong view of thinking, mere calculating is not thinking (and pocket calculators don't think), but on a weak, but unexciting, sense of thinking, pocket calculators do think. He closes with some observations on the implications of this conclusion. (shrink)

The American rock band KISS is notorious. Its notoriety derives not only from the band’s otherworldly costumes (except for of course during the unmasked period), the fact that they were inducted into the Rock and Roll Hall of Fame, their numerous hit records or the amazing stage theatrics and pyrotechnics of their live shows. It’s also related to the band’s constantly changing makeup (and I don’t mean the kind on their faces!). Of the four members, only Paul Stanley and Gene (...) Simmons were fixtures. With so many changes to the band’s composition, has KISS always remained the same band? Some see this head-scratcher as roughly similar to a conundrum in philosophical metaphysics (that’s the area of philosophy addressing problems of existence): the puzzle of Theseus’s ship. (shrink)

The problem considered in this chapter emerges from the tension we find when looking at the design and architecture of chatbots on the one hand and their conversational aptitude on the other. In the way that LLM chatbots are designed and built, we have good reason to suppose they don't possess second-order capacities such as intention, belief or knowledge. Yet theories of conversation make great use of second-order capacities of speakers and their audiences to explain how aspects of interaction succeed. (...) As we can all bear witness to now though, at the point of use chatbots appear capable of performing language tasks at a level close to that of humans. This creates a tension when we consider something like, for example, the classic Gricean theory of implicature. On a broad summary of this type of account, to utter p and implicate q requires the reflexive occurrence of an audience supposing a speaker believes that q, and the speaker believing that their audience can determine they believe it when they utter p. So taken at face value, if a chatbot doesn’t have the capacity for belief, then either in their role as speaker or audience, they would not seem capable of either generating or comprehending implicatures. Yet on the surface it does seem that chatbots are capable of dealing with (some) implicatures, and as such it raises questions about how we should then correlate this with what we think occurs in cases of implicature with chatbots.

Modern physics has cast doubt on Newton's idea of particles with definite properties. Do we have to go back to Aristotle for a new understanding of the ultimate nature of substance? If we ask, `what is the nature of substance?', we might be told that this substance is salt, that one is copper, or that the atomic nucleus is a mixture of protons and neutrons. But what are all these substances? What do they have in common which makes them substances? (...) We don't seem to think that such things as colours, numbers, or shapes are by themselves `substantial enough' to be substances in their own right. We therefore change our question to `what is it to be a substance?', or to `what is the ultimate nature of the simplest substances?'. (shrink)

It is common for young Christians to go off to college assured in their beliefs but, in the course of their first year or two, they meet what appears to them to be powerful defenses of scientific naturalism and crushing critiques of the basic Christian story (BCS), and many are thrown into doubt. They think to themselves something like this: "To be honest, I am troubled about the BCS. While the problem of evil, the apparent cultural basis for the diversity (...) of religions, the explanatory breadth of contemporary science, naturalistic explanations of religious experience and miracle reports, and textual and historical criticism of the Bible, among other things, don’t make me believe the BCS is false , I am in serious doubt about it, so much so that I lack belief of it. In that case, how can I have Christian faith? And if I don’t have faith, how can I keep on praying, attending church, affirming the creed, confessing my sins, taking the sacraments, singing the hymns and songs, and so on? I can’t, unless I’m a hypocrite. So integrity requires me to drop the whole thing and get out." Of course, our student is not alone. Many Christians find themselves for some portion of their lives somewhere on the trajectory from doubt to getting out. Indeed, Christians in the West struggle with intellectual doubt more than they used to, especially university-educated Christians. What should we say to them? Some will say “Get out!,” welcoming the development as a path to liberation. We explore a different response in this essay. (shrink)

Freud proposes that in unconscious processing, logical connections are also (heavily) based upon phonological similarities. Repressed concerns, for example, would also be expressed by way of phonologic ambiguity. In order to investigate a possible unconscious influence of phonological similarity, 31 participants were submitted to a tachistoscopic subliminal priming experiment, with prime and target presented at 1ms. In the experimental condition, the prime and one of the 2 targets were phonological reversed forms of each other, though graphemically dissimilar (e.g., “nice” and (...) “sign”); in the control condition the targets were pseudo-randomly attributed to primes to which they don’t belong. The experimental task was to “blindly” pick the choice most similar to the prime. ERPs were measured with a focus on the N320, which is known to react selectively to phonological mismatch in supraliminal visual word presentations. The N320 amplitude-effects at the electrodes on the midline and at the left of the brain significantly predicted the participants’ net behavioral choices more than half a second later, while their subjective experience is one of arbitrariness. Moreover, the social desirability score (SDS) significantly correlates with both the behavioral and the N320 brain responses of the participants. It is proposed that in participants with low SDS the phonological target induces an expected reduction of N320 and this increases their probability to pick this target. In contrast, high defensive participants have a perplexed brain reaction upon the phonological target, with a negatively peaking N320 as compared to control and this leads them to avoid this target more often. Social desirability, which is understood as reflecting defensiveness, might also manifest itself as a defense against the (energy-consuming) ambiguity of language. The specificity of this study is that all of this is happening totally out of awareness and at the level of very elementary linguistic distinctions. (shrink)

In this paper we don’t intend to show, against the sceptic, that most of our everyday beliefs about the external world are cases of knowledge. What we do try to show is that it is more rational to hold that most of such beliefs are actually cases of knowledge than to deny them this status, as the external world sceptic does. In some sense, our point of view is the opposite of Hume’s, who held that reason clearly favours scepticism about (...) the independent existence of an external world rather than common sense belief in such an independent existence. In arguing for the superior rationality of this common sense, Moorean view, we also take a fallibilist conception of knowledge to be rationally preferable to an infallibilist view of it. (shrink)

Philosophy, that most misunderstood of intellectual pursuits, is often mocked; and no part of philosophy is as often mocked as metaphysics. The image of the ‘speculative metaphysician’ dreaming up abstract pictures of the world has been held up for ridicule by poets, playwrights, novelists, journalists as well as by other philosophers. The Logical Positivists in the first half of the 20th Century rejected all metaphysical speculations as ‘meaningless’ since they could not be verified by scientific experiment; in the later part (...) of the century, Wittgenstein criticised systematic metaphysics as being a kind of intellectual disease resulting from our reading false pictures of the world into the grammar of our language. The common suspicion underlying many of these attacks is that ultimately, all metaphysics is a kind of nonsense, and that metaphysicians don’t really know what they are talking about. This suspicion is not new. Nicolas-Sébastien Chamfort commented in 1796, ‘I am tempted to say of metaphysicians what Scaliger used to say of the Basques: they are said to understand one another, but I don’t believe a word of it.’ Some contemporary philosophers may agree.

Recently, companions in guilt strategies have garnered significant philosophical attention as a response to arguments for moral error theory, the view that there are no moral facts and that our moral beliefs are thus systematically mistaken. According to Cuneo (The normative web: an argument for moral realism, Oxford University Press, Oxford, 2007), Das (Philos Q 66:152–160, 2016; Australas J Philos 95(1):58–69, 2017), Rowland (J Ethics Soc Philos 7(1):1–24, 2012; Philos Q 66:161–171, 2016) and others, epistemic facts would be just as (...) metaphysically problematic (or ‘guilty’) as moral facts. But since epistemic error theory is implausible, arguments for moral error theory prove too much and should be rejected. My aim is to argue that the success of this strategy is limited. In particular, the companions in guilt response fails against error-theoretic arguments motivated by concerns about explanatory dispensability, as recently developed by Joyce (The evolution of morality, MIT press, Bradford, 2005) and Olson (Moral error theory: history, critique, defence, Oxford University Press, Oxford, 2014: Ch. 7). To succeed, the response would require a prima facie plausible argument to the effect that epistemic facts are metaphysically dubious because they, too, are explanatorily dispensable. But, as I show, any such argument proves self-effacing: its premise commits us to believing in epistemic facts, while its conclusion forces us to deny their existence. Consequently, companions in guilt strategies don’t offer a panacea against arguments for moral error theory. (shrink)

This paper discusses an important puzzle about the semantics of indicative conditionals and deontic necessity modals (should, ought, etc.): the Miner Puzzle (Parfit, ms; Kolodny and MacFarlane, J Philos 107:115–143, 2010). Rejecting modus ponens for the indicative conditional, as others have proposed, seems to solve a version of the puzzle, but is actually orthogonal to the puzzle itself. In fact, I prove that the puzzle arises for a variety of sophisticated analyses of the truth-conditions of indicative conditionals. A comprehensive solution (...) requires rethinking the relationship between relevant information (what we know) and practical rankings of possibilities and actions (what to do). I argue that (i) relevant information determines whether considerations of value may be treated as reasons for actions that realize them and against actions that don’t, (ii) incorporating this normative fact requires a revision of the standard ordering semantics for weak (but not for strong) deontic necessity modals, and (iii) an off-the-shelf semantics for weak deontic necessity modals, due to von Fintel and Iatridou, which distinguishes “basic” and “higher-order” ordering sources, and interprets weak deontic necessity modals relative to both, is well-suited to this task. The prominence of normative considerations in our proposal suggests a more general methodological lesson: formal semantic analysis of natural language modals expressing normative concepts demands that close attention be paid to the nature of the underlying normative phenomena.

Suppose that a sign at the entrance of a hotel reads: “Don’t enter these premises unless you are accompanied by a registered guest”. You see someone who is about to enter, and you tell her: “Don’t enter these premises if you are an unaccompanied registered guest”. She asks why, and you reply: “It follows from what the sign says”. It seems that you made a valid inference from an imperative premise to an imperative conclusion. But it also seems that imperatives (...) cannot be true or false, so what does it mean to say that your inference is valid? It cannot mean that the truth of its premise guarantees the truth of its conclusion. One is thus faced with what is known as “Jørgensen’s dilemma” (Ross 1941: 55-6): it seems that imperative logic cannot exist because logic deals only with entities that, unlike imperatives, can be true or false, but it also seems that imperative logic must exist. It must exist not only because inferences with imperatives can be valid, but also because imperatives (like “Enter” and “Don’t enter”) can be inconsistent with each other, and also because one can apply logical operations to imperatives: “Don’t enter” is the negation of “Enter”, and “Sing or dance” is the disjunction of “Sing” and “Dance”. A standard reaction to this dilemma consists in basing imperative logic on analogues of truth and falsity. For example, the imperative “Don’t enter” is satisfied if you don’t enter and is violated if you enter, and one might say that an inference from an imperative premise to an imperative conclusion is valid exactly if the satisfaction (rather than the truth) of the premise guarantees the satisfaction of the conclusion. But before getting into the details, more needs to be said on what exactly imperatives are. (shrink)

Autonomous and automatic weapons would be fire and forget: you activate them, and they decide who, when and how to kill; or they kill at a later time a target you’ve selected earlier. Some argue that this sort of killing is always wrong. If killing is to be done, it should be done only under direct human control. (E.g., Mary Ellen O’Connell, Peter Asaro, Christof Heyns.) I argue that there are surprisingly many kinds of situation where this is false and (...) where the use of Automated Weapons Systems would in fact be morally required. These include cases where a) once one has activated a weapon expected then to behave lethally, it would be appropriate to let it continue because this is part of a plan whose goodness one was best positioned to evaluate before activating the weapon; b) one expects better long-term consequences from allowing it to continue; c) allowing it to continue would express a decision you made to be resolute, a decision that could not have advantaged you had it not been true that you would carry through with it; d) the weapon is mechanically not recallable, so that, to not allow it to carry through, you would have had to refrain from activating it in the first place, something you expected would have disastrous consequences; e) you must deputize necessary killings to autonomous machines in order to protect yourself from guilt you shouldn’t have to bear; f) it would be morally better for the burden of responsibility for the killing to be shared among several agents, and the agents deputizing killing to machines can do this, especially where it’s not predictable which machine will be successful; g) a killing would be morally better done with elements of randomness and lack of deliberation, and a (relatively stupid) machine could do this where a person could not; h) the machine would be acting as a Doomsday Device, so that it could not have had its hoped for deterrent effect had you not ensured that you would be unable to recall it if enemy action activated it; i) letting it carry through is a necessary part of its own learning process, and you expect that this learning will have salutary effects later on; j) human intervention in the machine’s operation would disastrously impair its precision, or its speed and efficiency; k) using non-automated methods would require human resources you just don’t have in a task that nevertheless must be done (e.g., using land-mines to protect remote installations); l) the weapon has such horrible and indiscriminate power that it is doubtful whether it could be actually used in ways compatible with International Humanitarian Law and the Laws of War, which require that weapons be used only in ways respecting distinctness, necessity and proportionality, but its threat of use could respect these principles in affording deterrence provided human error cannot lead to their accidental deployment, this requiring that they be controlled by carefully designed autonomous and automatic systems. I then consider objections based on conceptions of human dignity and find that very often dignity too is best served by autonomous machine killing. Examples include saving your village by activating a robot to kill invading enemies who would inflict great indignity on your village, using a suicide robot to save yourself from a less dignified death at enemy hands, using a robotic drone to kill someone otherwise not accessible in order to restore dignity to someone this person killed and to his family, and using a robot to kill someone who needs killing, but the killing of whom by a human executioner would soil the executioner’s dignity. I conclude that what matters in rightful killing isn’t necessarily that it be under the direct control of a human, but that it be under the control of morality; and that could sometimes require use of an autonomous or automated device. (This paper was formerly called "Fire and Forget: A Defense of the Use of Autonomous Weapons in War" on Philpapers; the current title is the title of the published version.). (shrink)

This article seeks the origin, in the theories of Ibn al-Haytham (Alhazen), Descartes, and Berkeley, of two-stage theories of spatial perception, which hold that visual perception involves both an immediate representation of the proximal stimulus in a two-dimensional ‘‘sensory core’’ and also a subsequent perception of the three dimensional world. The works of Ibn al-Haytham, Descartes, and Berkeley already frame the major theoretical options that guided visual theory into the twentieth century. The field of visual perception was the first area (...) of what we now call psychology to apply mathematics, through geometrical models as used by Euclid, Ptolemy, Ibn al-Haytham, and Descartes (among others). The article shows that Kepler’s discovery of the retinal image, which revolutionized visual anatomy and entailed fundamental changes in visual physiology, did not alter the basic structure of theories of spatial vision. These changes in visual physiology are advanced especially in Descartes' Dioptrics and his L'Homme. Berkeley develops a radically empirist theory vision, according to which visual perception of depth is learned through associative processes that rely on the sense of touch. But Descartes and Berkeley share the assertion that there is a two-dimensional sensory core that is in principle available to consciousness. They also share the observation that we don't usually perceived this core, but find depth and distance to be phenomenally immediate, a point they struggle to accommodate theoretically. If our interpretation is correct, it was not a change in the theory of the psychology of vision that engendered the idea of a sensory core, but rather the introduction of the theory into a new metaphysical context.

A Mathematical Review by John Corcoran, SUNY/Buffalo -/- Macbeth, Danielle Diagrammatic reasoning in Frege's Begriffsschrift. Synthese 186 (2012), no. 1, 289–314. ABSTRACT This review begins with two quotations from the paper: its abstract and the first paragraph of the conclusion. The point of the quotations is to make clear by the “give-them-enough-rope” strategy how murky, incompetent, and badly written the paper is. I know I am asking a lot, but I have to ask you to read the quoted passages—aloud if (...) possible. Don’t miss the silly attempt to recycle Kant’s quip “Concepts without intuitions are empty; intuitions without concepts are blind”. What the paper was aiming at includes the absurdity: “Proofs without definitions are empty; definitions without proofs are, if not blind, then dumb.” But the author even bollixed this. The editor didn’t even notice. The copy-editor missed it. And the author’s proof-reading did not catch it. In order not to torment you I will quote the sentence as it appears: “In a slogan: proofs without definitions are empty, merely the aimless manipulation of signs according to rules; and definitions without proofs are, if no blind, then dumb.”[sic] The rest of my review discusses the paper’s astounding misattribution to contemporary logicians of the information-theoretic approach. This approach was cruelly trashed by Quine in his 1970 Philosophy of Logic, and thereafter ignored by every text I know of. The paper under review attributes generally to modern philosophers and logicians views that were never espoused by any of the prominent logicians—such as Hilbert, Gödel, Tarski, Church, and Quine—apparently in an attempt to distance them from Frege: the focus of the article. On page 310 we find the following paragraph. “In our logics it is assumed that inference potential is given by truth-conditions. Hence, we think, deduction can be nothing more than a matter of making explicit information that is already contained in one’s premises. If the deduction is valid then the information contained in the conclusion must be contained already in the premises; if that information is not contained already in the premises […], then the argument cannot be valid.” Although the paper is meticulous in citing supporting literature for less questionable points, no references are given for this. In fact, the view that deduction is the making explicit of information that is only implicit in premises has not been espoused by any standard symbolic logic books. It has only recently been articulated by a small number of philosophical logicians from a younger generation, for example, in the prize-winning essay by J. Sagüillo, Methodological practice and complementary concepts of logical consequence: Tarski’s model-theoretic consequence and Corcoran’s information-theoretic consequence, History and Philosophy of Logic, 30 (2009), pp. 21–48. The paper omits definitions of key terms including ‘ampliative’, ‘explicatory’, ‘inference potential’, ‘truth-condition’, and ‘information’. The definition of prime number on page 292 is as follows: “To say that a number is prime is to say that it is not divisible without remainder by another number”. This would make one be the only prime number. The paper being reviewed had the benefit of two anonymous referees who contributed “very helpful comments on an earlier draft”. Could these anonymous referees have read the paper? -/- J. Corcoran, U of Buffalo, SUNY -/- PS By the way, if anyone has a paper that has been turned down by other journals, any journal that would publish something like this might be worth trying. (shrink)

Nuestro recorrido será el siguiente. En el capítulo primero examinamos la noción de unión del cuerpo y el alma que Descartes formula desde el inicio de Las pasiones del alma (§2), noción anticipada por otros textos (Principia II §2) pero muy original, y que recusa todo dualismo, en tanto concibe una unión no substancial, en la que el alma está unida, de modo más o menos estrecho, a todos los cuerpos que la afectan, como "corps de dehors", de manera tal (...) que todos los sentimientos, internos o externos, en tanto referidos al cuerpo, pueden ser ubicados en una misma exterioridad respecto al alma (sección §1). Esta noción de unión: a) coincide plenamente con la experiencia del poder o capacidad del alma para actuar sobre el cuerpo, o recibir la acción del cuerpo, de manera tal de excluir definitivamente toda referencia a la substancia espiritual, corporal o compuesta; b) establece una diferencia meramente cuantitativa entre mi cuerpo y los cuerpos del mundo, porque la unión al cuerpo es más o menos estrecha, según sea más o menos inmediata la acción del cuerpo sobre el alma. La primera consecuencia de lo anterior es la siguiente: Las pasiones del alma no establece distinción alguna entre sentimientos interiores y exteriores, porque el lugar del agente (las partes de nuestro cuerpo, los cuerpos del mundo) no sirven ya más como criterio para la distinción entre los modos de la sensibilidad (sección §2). Es precisamente en este punto fundamental que la investigación cartesiana sobre las pasiones se distingue definitivamente del análisis de la sensibilidad realizado en la cuarta parte de Los Principios de la Filosofía, en donde la pasión era considerada como un sentimiento interior, junto con los apetitos naturales (IV §190), por oposición a los cinco sentidos exteriores (IV §§ 191-195). Luego del examen de la definición de pasión, en el próximo capítulo, podremos preguntar: dadas, por un lado, la interioridad de la pasión al alma, y por otro, el emplazamiento de todos los cuerpos en el mismo afuera, «dehors», respecto del alma, ¿cabe buscar, en la pasión, el sentimiento de un corps de dedans? Anticipemos que la reforma conceptual de la unión del cuerpo y el alma exige y a la vez resulta de una reforma lexical especialmente interesante porque, al excluir toda referencia a las substancias o a la substancialidad de la unión, a) identifica esta última con la capacidad o potencia del alma de afectar o ser afectada por el cuerpo (sección §3); b) debe describir la unión como un «estar (del alma) junto (al cuerpo), ( être jointe)», que califica la estrechez de la unión por la inmediatez de la acción (sección §4). Finalmente, esta conjunción del alma y del cuerpo anticipa de manera coherente la doctrina cartesiana del amor, el cual se define por la capacidad del alma de unirse (« se joindre ») a los objetos que la afectan en la apariencia de bondad. El capítulo segundo se dedicará a la definición de pasión (Pasiones §§21-28), el único sentimiento interior al alma misma porque el único que es tal como aparece, en una evidencia que no puede ser entendida mas que en relación, todavía indeterminada, con la evidencia primera ego sum, ego existo, en la Meditación Segunda, y especialmente con su última formulación, en la certeza del « creo ver » («videre videor»). El carácter inaugural de esta definición reside en los puntos siguientes: a) la relación con el alma convierte a la pasión en el único sentimiento que es tal como se siente, pero al mismo tiempo, b) inaugura una nueva forma de error posible, todavía indeterminado, pero de otro orden que aquél al que nos somete la naturaleza extrínseca del resto de las percepciones (sección §1). Ahora bien, la pasión es tal como se siente porque no es un « ver », videre, y por lo tanto no le corresponde revelar el ego sum (« ego sum qui sentio » VII, 29, 11), a través de un « creo ver », videre videor (sección §3). Quisimos probar que esto es perfectamente coherente con la doble enumeración de los modos del pensamiento, en la Segunda y Tercera Meditación, (VII, 28 y 35, respectivamente) y con la clasificación de los pensamientos (ideas, juicios, voluntades, afecciones), establecida en la Meditación Tercera (VII, 38) (sección §2). Pero la pasión, a la vez que inaugura una interioridad, se recibe en el alma, como algo que no proviene de ella (Pasiones §17). Es aquí, donde se da a conocer el carácter inaugural y a la vez paradójico de la pasión: en ella, la interioridad del alma a sí se conoce, por primera vez, en una modalidad particular de la recepción sensible. Examinamos esa doble condición, interioridad y recepción, en la sección §7, la última de este segundo capítulo. Dos consecuencias. La primera: a partir de la definición de pasión, la investigación sobre la cualidad sensible se independiza del examen de la realidad objetiva (sección §4). La pasión puede por lo tanto inaugurar una verdad y un modo de error que se separa definitivamente del objeto representado como cosa o privación de cosa. No seremos los primeros en decir que la pasión, el saber afectivo en general, sólo puede dirigirse a un no-objeto (F. Alquié). Pero hay que agregar que la definición de pasión, al recuperar su evidencia primera, abre a la meditación el campo de una realidad inobjetivable, o, mejor, de una modalidad de la objetividad definitivamente irreal, que ya ha sido descubierta por J-L. Marion, por lo menos para el caso particular de la admiración, y que sólo podrá ser de ser descripta en el momento de definir las pasiones particulares. La segunda consecuencia reside en la relegación definitiva de toda explicación de la pasión por la causa eficiente (sección §6). En efecto, Descartes deja de lado las funciones del cuerpo como criterio de clasificación de los modos de la sensibilidad, y la relega a la segunda parte de la segunda parte de su definición, de manera tal que la causa de la pasión no explica nada y por el contrario, es ella la que debe ser explicada. Si se admite una doble constitución de la metafísica cartesiana, nuestro esfuerzo conduce a mostrar que la noción de pasión, y la investigación que ella abre, pertenece a una metafísica presidida por su primera figura, cogitatio, antes que por la segunda, causa. La investigación sobre los efectos de la pasión, que comprende los artículos §§40 a 48 de Las pasiones del alma, y a la que dedicamos nuestro capítulo III, debe ser leída en continuidad al texto de la Meditación Sexta, en tanto viene a responder a la pregunta siguiente: ¿cuál es el modo de la pasividad que caracteriza a la pasión y la distingue de otros modos del sentimiento como de otros modos de constricción a la voluntad? Si la pasión, se recibe en el alma, ¿cómo se siente esa proveniencia, si por definición queda excluida toda relación al cuerpo como causa o como objeto? En primer lugar, aquello que caracteriza a la pasión es que ella tiene como efecto una disposición a querer. Pero, dado que la voluntad es esencialmente libre, la disposición a querer en el alma tiene a su vez un efecto igualmente necesario, este es, una respuesta del alma a la disposición a querer que es en ella, respuesta que Descartes llama (no) consentimiento a los efectos de la pasión (§46; §80). A partir del artículo §40, la investigación sobre las pasiones se introduce resueltamente en el ámbito de una moral, como una ciencia de los efectos (sección §1). En segundo lugar, y por lo anterior, la pasión, puede ser, en su interioridad y proximidad al alma, directamente contraria a la voluntad (365, 12-13), justamente, porque ella es el único sentimiento que tiene como efecto necesario en el alma una disposición a querer (§40). Lejos de presentar un mero obstáculo a una determinación del alma, la pasión se recibe como una invitación, a la cual el alma debe imperativamente responder. El punto a destacar (sección §2) es el siguiente: Descartes describe aquí una verdadera autoafección indirecta, por la cual el alma puede excitar en sí una pasión voluntaria (362, 28 ; 363, 2; 486, 6-9), autoafección de la cual es absolutamente incapaz en el caso del resto de los sentimientos, tal como quedaba establecido desde la Meditación Sexta. Así, el cuerpo que actúa inmediatamente sobre el alma, al cual ella está más estrechamente unida, abandona su condición de mero intermediario entre los cuerpos y el alma y pasa a ser, en una autoafección voluntaria, el intermediario entre una acción del alma y una pasión en el alma. En la sección §3 se agrega esto: la pasión, a diferencia de todos los sentimientos, no se siente en el instante. Por el contrario, en ella, el sentir se despliega en el tiempo y se hace por lo tanto independiente de la acción de los cuerpos sobre los sentidos internos o externos. Esto se debe a lo siguiente: primero, en la pasión, el cuerpo actúa como una totalidad indivisible. Segundo: el cuerpo actúa sobre sí. En la pasión, tercero, el cuerpo actúa de manera tal que su acción se presenta siempre como una exigencia al ejercicio efectivo de la libertad. Finalmente, en la pasión, la totalidad de las funciones del cuerpo se someten definitivamente a la voluntad, de manera que el alma puede afectarse a sí en una pasión voluntaria. Quisiéramos proponer (sección §3) que la experiencia del cuerpo en la pasión merece ser nombrada como la experiencia de un cuerpo de dedans, que se presenta en la repugnancia o el consentimiento y cuya acción no se siente en un lugar (en una internidad que no establece ninguna distinción con la exterioridad de los cuerpos del mundo), sino en el alma misma, en una interioridad que hace imposible la reducción del cuerpo sentido a la categoría común de objeto o causa. Ahora bien, la investigación sobre la pasión puede introducirse en el ámbito de la moral con una condición: que la pasión permita el acceso del ego a un alter ego, o según la fórmula tradicional utilizada por Descartes, a un «otro sí mismo», alter ipse. Es el problema que abordamos en el capítulo IV. Queda claro que las Meditaciones Metafísicas impiden, o mejor, ocluyen de modo parentemente definitivo, ese acceso. Pero, en Las pasiones del alma, Descartes, introduce un género muy particular de objeto , «otros objetos, que consideramos causas libres, capaces de hacer el bien y el mal » (§55, 374, 5-7). Más aún, la libertad del agente se erige en criterio de clasificación de segundo orden para todas las pasiones simples, con excepción del deseo. El punto a notar aquí (sección §1) es el siguiente: el ego no se ve afectado por la causa libre porque infiera que ella, a diferencia de otras, actúa moralmente sobre él, con independencia de toda determinación mecánica. Es al revés: el ego siente la acción de una causa libre porque se ve afectado por la libertad del agente; es esa afección la que otorga a los actos del otro el carácter moral de buenos o malos. Esto se prueba en el respeto o la veneración (§162): aquello que nos afecta no es la supuesta bondad o la maldad de los actos, sino inmediatamente aquello que los hace tales, esto es, la « capacidad » de hacer el bien o el mal. De aquí que el hijo, cuyos actos evidentemente no son morales, pueda nombrarse, entre los objetos de amor, como un « otro(s) sí mismo» (§82, 389, 15). A fin de precisar el sentido y los alcances de esta alteridad, debemos detenernos en la definición cartesiana del amor (secciones §§2-3). Esa definición debe, en primer lugar, distinguirse claramente de aquella que Descartes había ensayado dos años antes, en la carta a Chanut del 1 de febrero de 1647. El problema que preocupa a Descartes no es ya más la definición de un amor intelectual, sino la de un amor puro, que Descartes distingue precisamente de las pasiones que « participan del amor » (§82, título), mezcla de deseo y « otras pasiones particulares » (§82 389, 9-10). El amor puro es una pasión que no tiene relación alguna al cuerpo, porque se siente sin placer y es la primera de las pasiones « que pertenecen al alma », según la distinción establecida en los títulos de §137 y §139. Esta distinción se establece estrictamente dentro del ámbito del amor pasión porque no considera en ningún momento el alma en tanto separada del cuerpo, condición del amor intelectual (IV, 602, 4-8), sino como « nuestra mejor parte » (§139, 432, 5). El único que merece sin reparos el título de « amor puro » es el amor paterno, el único en el que se cumple la tríada, pureza, posesión perfecta, alteridad. En la sección §4 nos detenemos en los modos del engaño propio de las pasiones, en general, y del amor en particular, para entender el último rasgo que Descartes le otorga al amor puro, este es, el de ser un amor verdadero, que elude todas las formas de engaño a las que las pasiones pueden someternos, y puede por lo tanto ocupar el lugar del verdadero conocimiento. La teoría cartesiana del amor permite así dos conclusiones. Primera: la alteridad sirve para distinguir definitivamente el amor del deseo, el amor puro de las pasiones que participan de él, los grados de perfección del amor, amor paterno, amistad honesta, y, finalmente, la formas del amor, afección, amistad y devoción. Segundo, antes de toda reflexión sobre el deseo, es decir, antes de considerar la perfectibilidad del ego por la posesión de bienes que dependan exclusivamente de nuestra voluntad, Descartes escribe que el alma se perfecciona en el amor, por la unión al bien verdadero, mientras que se envilece y rebaja en su unión con un bien excesivamente estimado (§139, 432, 12-20 ; §142, 435, 18 –22). En la sección §5 examinamos el efecto del amor, la benevolencia, que Descartes, haciendo caso omiso de la tradición, define como una verdadera beneficencia, como un acto de donación, que no necesita de ningún deseo para hacerse efectivo. El punto a destacar aquí es que Descartes considera que el otro al que el alma se une es la « mejor parte » del todo que resulta de la unión (§82, 389, 16-17). Por este exceso, el generoso, sobre la estrechez de la unión al cuerpo, decide por la estrechez de la unión a otra alma, y privilegia el objeto de amor sobre el amor a la vida. Brevemente: la amistad cartesiana tiende a la devoción y rompe con toda noción de amistad fundada en la igualdad. Esto nos permite, en la sección §6 hacer notar cómo la teoría del amor resignifica un léxico que Descartes recibe de Aristóteles y Santo Tomás. La comparación, al menos inicial, con esos autores está dirigida a incluir a Descartes en una historia del amor. El quinto capítulo traza el largo itinerario de la noción de virtud, a través de la Correspondencia, y se detiene especialmente en las cartas mencionadas más arriba, ( a Elisabeth, 15 septiembre 1645; a Chanut, 1 febrero 1648) en las que Descartes ensaya y abandona una primera forma de moral definitiva, especialmente problemática, en tanto aspira, por primera vez, a deducir el amor a Dios de la idea de Dios, y se dirige a pensar al ego como parte de totalidades (familia, vecindad, Estado) que han sido, ellas también, creadas por Dios. Esta reflexión sobre el amor a Dios es todavía independiente de la reflexión sobre las pasiones, que recién comienza. Intentamos aquí despejar la intención cartesiana que puede resumirse así: de la misma manera que Dios, creador de toda verdad, es fundamento de toda ciencia y toda verdad se halla ya contenida en Su idea, es Dios, creador de totalidades físicas, sociales o políticas, el fundamento de todo amor, aunque no se lo conozca, o sólo confusamente, como tal; de modo que en todo acto de renuncia por la totalidad, amamos a Dios, en un amor sensible, aunque nada en Él sea imaginable. Sin embargo, una vez adquirida, en Las pasiones del alma, la definición de pasión e incluida la noción de consentimiento en la definición definitiva del amor, aquella vía de análisis, que parte de un ego ya incluido en las totalidades de las que forma parte como persona, agota definitivamente sus posibilidades y debe ser abandonada. Debemos preguntar, entonces: qué queda de esta ardua reflexión sobre el amor a Dios en Las pasiones del alma? Principalmente, Descartes recupera de aquellas cartas la reflexión sobre la Providencia divina, en los artículos §§146-147. Pero entre las cartas de 1645-1647 y el texto de Las pasiones del alma, hay una diferencia capital. La reflexión sobre la Providencia divina, en 1649, no hace mención alguna al amor, parece abandonar toda aspiración a fundar, en el amor a Dios, el amor a otros hombres y se dirige exclusivamente a establecer la regla del deseo, intermediario privilegiado entre pasión y acción (§143, 435, 26-29). Ahora bien, una moral que no tuviera otra regla que la del deseo presentaría dos características distintivas. Primero, la indagación sobre el bien verdadero se agota en la determinación del bien verdaderamente posible; son pues igualmente buenos todos los bienes igualmente estimables e igualmente posibles. De aquí, en segundo lugar, que la noción de virtud no pueda otorgar a la voluntad otro bien que su mero ejercicio, vacío de todo contenido. Ha sido pues posible interpretar que, la moral cartesiana, en el momento de alcanzar su fundamento, se independiza de ella, como otra potencia igualmente arbitraria, que no puede someterse a otro fin que el de imitar a Dios por la inmutabilidad de la decisión. En el capítulo sexto, dedicado a la definición de generosidad, nosotros propondremos, al contrario, que el texto de Las pasiones del alma, cuya teoría del amor aquella interpretación debe desconocer, permite otra lectura de la moral cartesiana. Sucede que Descartes cambia radicalmente el punto de partida de su reflexión : en las cartas de 1645-1647, la omnipotencia divina exigía considerar el ego como parte de distintas totalidades, a las que se haya ligado de hecho. En 1649, la unión no describe una situación existencial, impuesta por nacimiento, vecindad o juramento, porque no accede a una situación de hecho más que por el consentimiento libre y lúcido del ego a la unión efectiva con el bien amado. De aquí, proponemos, se siguen dos consecuencias. La primera (sección §2): una reformulación del problema del amor a Dios. La omnipotencia divina no se conoce como aquí como Providencia, es decir, en el decreto universal que determina la fatalidad de todas las cosas, sino en el acto singular de una donación personal y desmedida, la libre disposición de nuestras voluntades, por la cual la criatura se reconoce semejante a su Creador (§152). El generoso reconoce que el libre albedrío, el único bien por el cual puede estimarse a sí mismo, es, tal como quedaba establecido desde la Meditación Cuarta, un don divino y el reconocimiento por un don recibido es una pasión, la gratitud, la cual, a diferencia de la admiración, la esperanza o la seguridad, es una especie del amor, siempre virtuosa (§§193-194). En efecto, la reflexión sobre la Providencia, es apenas uno de los modos de reglar el deseo, el segundo, porque el primero es, justamente, la generosidad, que se define con total prescindencia del conocimiento de la fatalidad de todas las cosas (§145, 437, 27-438, 3). Investigamos aquí los tres rasgos del don divino: infinitud formal, pertenencia verdadera, distribución perfecta. La segunda consecuencia, que confirma la primera (secciones §§3-4), es la reformulación del amor a otros hombres. En efecto, no arriesgaremos demasiado al proponer que la definición de generosidad, lejos de agotarse en los artículos §§152-153, comprende los artículos §154 y §155 y culmina, finalmente, en el §156. Así entendida, la generosidad es una autoafección que, como tal, determina, prioritaria y precisamente, el modo en que el generoso es afectado por los otros hombres, en tanto causas libres, semejantes al ego, y por lo tanto semejantes a Dios. La generosidad se define pues en el horizonte de la alteridad porque el generoso no sería tal si no estimara a todos y cada uno de los hombres como generosos posibles (§154) y si no redescubriera su capacidad de hacer el mal por comparación al mal efectivamente realizado por ellos (§155). De aquí, finalmente, la regla definitiva de la moral cartesiana (§156), regla que, al definir la mejor acción posible, otorga un contenido definitivo a la firme resolución de hacer el bien, esta es: imitar la donación original, haciendo el bien a todos los hombres. Luego, la ausencia de una reflexión sobre el amor a Dios, en Las pasiones del alma, no es, todavía, una desaparición, ya que el acto de donación divina condiciona definitivamente la regla moral como una imitación, que se concibe como una repetición, igualmente gratuita, de aquella donación original. La relación entre ambos puntos se prueba en lo siguiente: Descartes afirma que el efecto necesario de la benevolencia generosa, la gratitud es uno de las principales vínculos de la sociedad entre los hombres (§194, 474, 13-15), la cual se funda pues en el mismo vínculo que une al hombre generoso con Dios: gratitud por la gratuidad de la donación (sección §6). La afirmación cartesiana es de un laconismo insalvable, pero recupera un texto hasta aquí descuidado, la Carta a Voetius de 1643, la primera reflexión cartesiana sobre el amor y la única dedicada a examinar las leyes que de él se deducen, como una jus caritatis (sección §7). Examinamos en la seccción §8 la problemática relación, o ausencia de relación, entre esas leyes de amistad y la ley civil, jus civile, basada en la autoridad del Príncipe. Finalmente, en la Conclusión, podemos detenernos en un problema ya dos veces pospuesto, este es, el que resulta de la equivalencia que Descartes establece entre amistad honesta y caridad cristiana. (IV, 309, 2-4; IV , 612, 14), equivalencia que la noción de generosidad está lejos de contradecir y que recupera la «gran afinidad» (VIII-2, 112, 24-25) entre las leyes de la amistad y las leyes de caridad, que Descartes había desarrollado en aquel capítulo séptimo de la Carta a Voetius. El carácter problemático de esta equivalencia es evidente: si el amor natural, por exceso, aspira a la caridad, es a riesgo que la caridad, por defecto, deje de ser cristiana. Esa afinidad no ha merecido mayor atención por parte de la metafísica y de sus historiadores. Pero, ha merecido la mayor atención por parte de la destitución de la metafísica que lleva a cabo Blaise Pascal quien descubre y acusa, en esa afinidad, el último esfuerzo de la filosofía cartesiana, dirigida a otorgarle al ego su última y más controversial primacía, la del acceso a Dios por el amor. -/- .

In this paper, I explore and examine different ways in which affectivity is related to perception within ecological psychology. I assess whether some of those ways compromise the realist and direct aspects of traditional ecological perception. I sustain that they don’t. Affectivity, at least in some cases, turns the perception of fine-grained affordances possible. For an engaged perceiver, affectivity is not optional.

Many theories in philosophy, law, and psychology, make no distinction in meaning between causing and enabling conditions. Yet, psychologically people readily make such distinctions each day. In this paper we report three experiments, showing that individuals distinguish between causes and enabling conditions in brief descriptions of wrongful outcomes. Respondents rate actions that bring about outcomes as causes, and actions that make possible the causal relation as enablers. Likewise, causers (as opposed to enablers) are rated as more responsible for the outcome, (...) as liable to longer prison sentences, and as liable to pay higher fines. Moreover, the more actors involved, the more blame volume there is psychologically to be apportioned between them. The implication is that theories and the law in practice, both criminal and civil, may dangerously mismatch the intuitions of those to whom they are supposed to apply. The findings are discussed in light of contemporary psychological theories of how people reason about cause. -/- The paper presents the extended findings supplementary to the conference paper: Frosch, C.

This is not a perfect book, but it is unique, and if you skim the first 400 or so pages, the last 300 (of some 700) are a pretty good attempt to apply what's known about behavior to social changes in violence and manners over time. The basic topic is: how does our genetics control and limit social change? Surprisingly he fails to describe the nature of kin selection (inclusive fitness) which explains much of animal and human social life. He (...) also (like nearly everyone) lacks a clear framework for describing the logical structure of rationality (LSR—John Searle’s preferred term) which I prefer to call the Descriptive Psychology of Higher Order Thought (DPHOT). He should have said something about the many other ways of abusing and exploiting people and the planet, since these are now so much more severe as to render other forms of violence nearly irrelevant. Extending the concept of violence to include the global long-term consequences of replication of someone’s genes, and having a grasp of the nature of how evolution works (i.e., kin selection) will provide a very different perspective on history, current events, and how things are likely to go in the next few hundred years. One might start by noting that the decrease in physical violence over history has been matched (and made possible) by the constantly increasing merciless rape of the planet (i.e., by people's destruction of their own descendant’s future). Pinker (like most people most of the time) is often distracted by the superficialities of culture when it’s biology that matters. See my recent reviews of Wilson’s ‘The Social Conquest of Earth’ and Nowak and Highfield’s ‘SuperCooperators’ here and on the net for a brief summary of the vacuity of ‘true altruism’ (group selection), and the operation of kin selection and the uselessness and superficiality of describing behavior in cultural terms. -/- This is the classic nature/nurture issue and nature trumps nurture --infinitely. What really matters is the violence done to the earth by the relentless increase in population and resource destruction (due to medicine and technology and conflict suppression by police and military). About 200,000 more people a day (another Las Vegas every 10 days, another Los Angeles every month), the 6 tons or so of topsoil going into the sea/person/year –about 1% of the world’s total disappearing yearly, etc. mean that unless some miracle happens the biosphere and civilization will largely collapse during next two centuries, and there will be starvation, misery and violence of every kind on a staggering scale. People's manners, opinions and tendencies to commit violent acts are of no relevance unless they can do something to avoid this catastrophe, and I don't see how that is going to happen. There is no space for arguments, and no point either (yes I'm a fatalist), so I'll just make a few comments as though they were facts. Don't imagine I have a personal stake in promoting one group at the expense of others. I am 78, have no descendants and no close relatives and do not identify with any political, national or religious group and regard the ones I belong to by default as just as repulsive as all the rest. -/- Parents are the worst Enemies of Life on Earth and, taking the broad view of things, women are as violent as men when one considers the fact that women's violence (like most of that done by men) is largely done in slow motion, at a distance in time and space and mostly carried out by proxy -by their descendants and by men. Increasingly, women bear children regardless of whether they have a mate and the effect of stopping one woman from breeding is on average much greater than stopping one man, since they are the reproductive bottleneck. One can take the view that people and their offspring richly deserve whatever misery comes their way and (with rare exceptions) the rich and famous are the worst offenders. Meryl Streep or Bill Gates or J.K Rowling and each of their kids may destroy 50 tons of topsoil each per year for generations into the future, while an Indian farmer and his may destroy 1 ton. If someone denies it that's fine, and to their descendants I say "Welcome to Hell on Earth"(WTHOE). -/- The emphasis nowadays is always on Human Rights, but it is clear that if civilization is to stand a chance, Human Responsibilities must replace Human Rights. Nobody gets rights without being a responsible citizen and the first thing this means is minimal environmental destruction. The most basic responsibility is no children unless your society asks you to produce them. A society or a world that lets people breed at random will always be exploited by selfish genes until it collapses (or reaches a point where life is so horrific it's not worth living). If society continues to maintain Human Rights as primary, to their descendants one can say with confidence "WTHOE". -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

The impressive variation amongst biological individuals generates many complexities in addressing the simple-sounding question what is a biological individual? A distinction between evolutionary and physiological individuals is useful in thinking about biological individuals, as is attention to the kinds of groups, such as superorganisms and species, that have sometimes been thought of as biological individuals. More fully understanding the conceptual space that biological individuals occupy also involves considering a range of other concepts, such as life, reproduction, and agency. There has (...) been a focus in some recent discussions by both philosophers and biologists on how evolutionary individuals are created and regulated, as well as continuing work on the evolution of individuality.

Some of the most interesting recent work in formal epistemology has focused on developing accuracy-based approaches to justifying Bayesian norms. These approaches are interesting not only because they offer new ways to justify these norms, but because they potentially offer a way to justify all of these norms by appeal to a single, attractive epistemic goal: having accurate beliefs. Recently, Easwaran & Fitelson (2012) have raised worries regarding whether such “all-accuracy” or “purely alethic” approaches can accommodate and justify evidential Bayesian (...) norms. In response, proponents of purely alethic approaches, such as Pettigrew (2013b) and Joyce (2016), have argued that scoring rule arguments provide us with compatible and purely alethic justifications for the traditional Bayesian norms, including evidential norms. In this paper I raise several challenges to this claim. First, I argue that many of the justifications these scoring rule arguments provide are not compatible. Second, I raise worries for the claim that these scoring rule arguments provide purely alethic justifications. Third, I turn to assess the more general question of whether purely alethic justifications for evidential norms are even possible, and argue that, without making some contentious assumptions, they are not. Fourth, I raise some further worries for the possibility of providing purely alethic justifications for content-sensitive evidential norms, like the Principal Principle. (shrink)

Sensory substitution devices (SSDs) aim to compensate for the loss of a sensory modality, typically vision, by converting information from the lost modality into stimuli in a remaining modality. “The vOICe” is a visual-to-auditory SSD which encodes images taken by a camera worn by the user into “soundscapes” such that experienced users can extract information about their surroundings. Here we investigated how much detail was resolvable during the early induction stages by testing the acuity of blindfolded sighted, naïve vOICe users. (...) Initial performance was well above chance. Participants who took the test twice as a form of minimal training showed a marked improvement on the second test. Acuity was slightly but not significantly impaired when participants wore a camera and judged letter orientations “live”. A positive correlation was found between participants' musical training and their acuity. The relationship between auditory expertise via musical training and the lack of a relationship with visual imagery, suggests that early use of a SSD draws primarily on the mechanisms of the sensory modality being used rather than the one being substituted. If vision is lost, audition represents the sensory channel of highest bandwidth of those remaining. The level of acuity found here, and the fact it was achieved with very little experience in sensory substitution by naïve users is promising. (shrink)

many things were back to front in 20th century analytic philosophy.

Decision-making under normative uncertainty requires an agent to aggregate the assessments of options given by rival normative theories into a single assessment that tells her what to do in light of her uncertainty. But what if the assessments of rival theories differ not just in their content but in their structure -- e.g., some are merely ordinal while others are cardinal? This paper describes and evaluates three general approaches to this "problem of structural diversity": structural enrichment, structural depletion, and multi-stage (...) aggregation. All three approaches have notable drawbacks, but I tentatively defend multi-stage aggregation as least bad of the three. (shrink)

This paper is a critical comment on an article of David Widerker which also appeared in the Journal of Philosophy. In this article, Wideker held, against positions previously defended by him, that in was possible to design effective counterexamples, in the line initiated by Harry Frankfurt in 1969, to the so-called “Principle of Alternative Possibilities”. The core of my criticism of Widerker is to deny that agents, in his putative counterexamples, are morally responsible for their decisions, owing to the fact (...) they are not able to respond appropriately to moral reasons.

There is considerable philosophical dispute about what it takes for an action to be evil. The methodological assumption underlying this dispute is that there is a single, shared folk conception of evil action deployed amongst culturally similar people. Empirical research we undertook suggests that this assumption is false. There exist, amongst the folk, numerous conceptions of evil action. Hence, we argue, philosophical research is most profitably spent in two endeavours. First, in determining which (if any) conception of evil action we (...) have prudential or moral (or both) reason to deploy, and second, in determining whether we could feasibly come to adopt that conception as the single shared conception given our psychological make-up and the content of the conceptions currently deployed.

This pair of articles provides a critical commentary on contemporary approaches to statistical mechanical probabilities. These articles focus on the two ways of understanding these probabilities that have received the most attention in the recent literature: the epistemic indifference approach, and the Lewis-style regularity approach. These articles describe these approaches, highlight the main points of contention, and make some attempts to advance the discussion. The second of these articles discusses the regularity approach to statistical mechanical probabilities, and describes some areas (...) where further research is needed. (shrink)

Video-game play (particularly “action” video-games) holds exciting promise as an activity that may provide generalized enhancement to a wide range of perceptual and cognitive abilities (for review see Latham et al., 2013a). However, in this article we make the case that to assess accurately the effects of video-game play researchers must better characterize video-game experience and expertise. This requires a more precise and objective assessment of an individual's video-game history and skill level, and making finer distinctions between video-games that fall (...) under the umbrella of “action” games. Failure to consider these factors may partly be responsible for mixed findings (see Boot et al., 2011). (shrink)

It is now well-known that Newton–Cartan theory is the correct geometrical setting for modelling the quantum Hall effect. In addition, in recent years edge modes for the Newton–Cartan quantum Hall effect have been derived. However, the existence of these edge modes has, as of yet, been derived using only orthodox methodologies involving the breaking of gauge-invariance; it would be preferable to derive the existence of such edge modes in a gauge-invariant manner. In this article, we employ recent work by Donnelly (...) and Freidel in order to accomplish exactly this task. Our results agree with known physics, but afford greater conceptual insight into the existence of these edge modes: in particular, they connect them to subtle aspects of Newton–Cartan geometry and pave the way for further applications of Newton–Cartan theory in condensed matter physics.
