Much of the debate about the mathematical refutation of Zeno’s paradoxes surrounds the logical possibility of completing supertasks—tasks made up of an infinite number of subtasks. Max Black and J.F. Thomson attempt to show that supertasks entail logical contradictions, but their arguments come up short. In this paper, I take a different approach to the mathematical refutations. I argue that even if supertasks are possible, we do not have a non-question-begging reason to think that Achilles’ supertask is possible. The justification (...) for the possibility of Achilles’ supertask lies in the possibility of him completing other supertasks of the same kind, and the justification for the possibility of him completing these other supertasks lies in the possibility of him completing yet more supertasks ad infinitum.

This volume collects a set of papers that were presented at a conference on “Big Questions in Free Will,” held at the University of Saint Thomas in October of 2014. It is dedicated to its editor, who passed away shortly after completing the manuscript. I will briefly summarize each of the 11 chapters and then offer a few critical comments.

In this book review I argue that, broadly speaking, there are three rival accounts of the relationship between having a normative reason to act and being motivated to act. Neo-Humeans argue that an agent has a normative reason to act if and only if so doing would satisfy some desire of the agent; consequently, their task is to show that there is an internal relation between an agent’s having a normative reason to act and an agent’s having a desire to (...) act. Kantians argue that any agent who has a normative reason to act, and who is practically rational (i.e., not suffering from some debilitating form of practical irrationality, such as weakness of will or depression), will act; consequently, their task is to show that normative reasons always have overriding authority and that it is always irrational not to act upon them. Neo-Aristotelians argue that normative reasons for action are derived from facts about human well-being, and that an agent will be motivated to act provided that she has been habituated into having desires, guided by reason, to act for her own well-being; consequently, their task is to show how normative reasons can be derived from facts about human well-being and whether it is always in an agent’s best interest to act morally.

Interpreters have found it exceedingly difficult to understand how Hume could be right in claiming that his two definitions of ‘cause’ are essentially the same. As J. A. Robinson points out, the definitions do not even seem to be extensionally equivalent. Don Garrett offers an influential solution to this interpretative problem, one that attributes to Hume the reliance on an ideal observer. I argue that the theoretical need for an ideal observer stems from an idealized concept of definition, which (...) many interpreters, including Garrett, attribute to Hume. I argue that this idealized concept of definition indeed demands an unlimited or infinite ideal observer. But there is substantial textual evidence indicating that Hume disallows the employment of idealizations in general in the sciences. Thus Hume would reject the idealized concept of definition and its corresponding ideal observer. I then put forward an expert-relative reading of Hume’s definitions of ‘cause’, which also renders both definitions extensionally equivalent. On the expert-relative reading, the meaning of ‘cause’ changes with better observations and experiments, but it also allows Humean definitions to play important roles within our normative practices. Finally, I consider and reject Henry Allison’s argument that idealized definitions and their corresponding infinite minds are necessary for expert reflection on the limitations of current science.

This paper offers both a theoretical and an experimental perspective on the relationship between connectionist and Classical (symbol-processing) models. Firstly, a serious flaw in Fodor and Pylyshyn’s argument against connectionism is pointed out: if, in fact, a part of their argument is valid, then it establishes a conclusion quite different from that which they intend, a conclusion which is demonstrably false. The source of this flaw is traced to an underestimation of the differences between localist and distributed representation. It has (...) been claimed that distributed representations cannot support systematic operations, or that if they can, then they will be mere implementations of traditional ideas. This paper presents experimental evidence against this conclusion: distributed representations can be used to support direct structure-sensitive operations, in a man- ner quite unlike the Classical approach. Finally, it is argued that even if Fodor and Pylyshyn’s argument that connectionist models of compositionality must be mere implementations were correct, then this would still not be a serious argument against connectionism as a theory of mind.

Believing that p, assuming that p, and imagining that p involve regarding p as true—or, as we shall call it, accepting p. What distinguishes belief from the other modes of acceptance? We claim that conceiving of an attitude as a belief, rather than an assumption or an instance of imagining, entails conceiving of it as an acceptance that is regulated for truth, while also applying to it the standard of being correct if and only if it is true. We argue (...) that the second half of this claim, according to which the concept of belief includes a standard of correctness, is required to explain the fact that the deliberative question whether to believe that p is transparent to the question whether p. This argument raises various questions. Is there such a thing as deliberating whether to believe? Is the transparency of the deliberative question whether to believe that p the same as the transparency of the factual question whether I do believe that p? We will begin by answering these questions and then turn to a series of possible objections to our argument. (shrink)

Artificial agents (AAs), particularly but not only those in Cyberspace, extend the class of entities that can be involved in moral situations. For they can be conceived of as moral patients (as entities that can be acted upon for good or evil) and also as moral agents (as entities that can perform actions, again for good or evil). In this paper, we clarify the concept of agent and go on to separate the concerns of morality and responsibility of agents (most (...) interestingly for us, of AAs). We conclude that there is substantial and important scope, particularly in Computer Ethics, for the concept of moral agent not necessarily exhibiting free will, mental states or responsibility. This complements the more traditional approach, common at least since Montaigne and Descartes, which considers whether or not (artificial) agents have mental states, feelings, emotions and so on. By focussing directly on mind-less morality we are able to avoid that question and also many of the concerns of Artificial Intelligence. A vital component in our approach is the Method of Abstraction for analysing the level of abstraction (LoA) at which an agent is considered to act. The LoA is determined by the way in which one chooses to describe, analyse and discuss a system and its context. The Method of Abstraction is explained in terms of an interface or set of features or observables at a given LoA. Agenthood, and in particular moral agenthood, depends on a LoA. Our guidelines for agenthood are: interactivity (response to stimulus by change of state), autonomy (ability to change state without stimulus) and adaptability (ability to change the transition rules by which state is changed) at a given LoA. Morality may be thought of as a threshold defined on the observables in the interface determining the LoA under consideration. An agent is morally good if its actions all respect that threshold; and it is morally evil if some action violates it. That view is particularly informative when the agent constitutes a software or digital system, and the observables are numerical. Finally we review the consequences for Computer Ethics of our approach. In conclusion, this approach facilitates the discussion of the morality of agents not only in Cyberspace but also in the biosphere, where animals can be considered moral agents without their having to display free will, emotions or mental states, and in social contexts, where systems like organizations can play the role of moral agents. The primary cost of this facility is the extension of the class of agents and moral agents to embrace AAs. (shrink)

Weak particularism about reasons is the view that the normative valency of some descriptive considerations varies, while others have an invariant normative valency. A defence of this view needs to respond to arguments that a consideration cannot count in favour of any action unless it counts in favour of every action. But it cannot resort to a global holism about reasons, if it claims that there are some examples of invariant valency. This paper argues for weak particularism, and presents a (...) framework for understanding the relationships between practical reasons. A central part of this framework is the idea that there is an important kind of reason-a 'presumptive reason'-which need not be conclusive, but which is neither pro tanto nor prima facie. /// [Richard Holton] Should particularists about ethics claim that moral principles are never true? Or should they rather claim that any finite set of principles will not be sufficient to capture ethics? This paper explores and defends the possibility of embracing the second of these claims whilst rejecting the first, a position termed 'principled particularism'. The main argument that particularists present for their position-the argument that holds that any moral conclusion can be superseded by further considerations-is quite compatible with principled particularism; indeed, it is compatible with the idea that every true moral conclusion can be shown to follow deductively from a finite set of premises. Whilst it is true that these premises must contain implicit ceteris paribus clauses, this does not render the arguments trivial. On the contrary, they can do important work in justifying moral conclusions. Finally the approach is briefly applied to the related field of jurisprudence. (shrink)

We investigate claims about the frequency of "know" made by philosophers. Our investigation has several overlapping aims. First, we aim to show what is required to confirm or disconfirm philosophers’ claims about the comparative frequency of different uses of philosophically interesting expressions. Second, we aim to show how using linguistic corpora as tools for investigating meaning is a productive methodology, in the sense that it yields discoveries about the use of language that philosophers would have overlooked if they remained in (...) their "armchairs of an afternoon", to use J.L. Austin’s phrase. Third, we discuss facts about the meaning of "know" that so far have been ignored in philosophy, with the aim of reorienting discussions of the relevance of ordinary language for philosophical theorizing.

The received view is that Kant denies all moral luck. But I show how Kant affirms constitutive moral luck in passages concerning radical evil from Religion within the Boundaries of Mere Reason. First, I explicate Kant’s claims about radical evil. It is a morally evil disposition that all human beings have necessarily, at least for the first part of their lives, and for which they are blameworthy. Second, since these properties about radical evil appear to contradict Kant’s even more famous (...) claims about imputation, ‘ought implies can’, and free will, I unpack Henry Allison’s proof of radical evil and show how it is consistent with interpretations of Kant’s broader views about morality. Third, I define and illustrate the category of constitutive moral luck and argue that Kant embraces the existence of constitutive moral luck given Allison-style interpretations of radical evil. This provides a reason for philosophers to reject the received view, and it creates an occasion for Kantians and Kant scholars to check their reasons if they deny moral luck. (shrink)

This paper examines three accounts of the sleeping beauty case: an account proposed by Adam Elga, an account proposed by David Lewis, and a third account defended in this paper. It provides two reasons for preferring the third account. First, this account does a good job of capturing the temporal continuity of our beliefs, while the accounts favored by Elga and Lewis do not. Second, Elga’s and Lewis’ treatments of the sleeping beauty case lead to highly counterintuitive consequences. The proposed (...) account also leads to counterintuitive consequences, but they’re not as bad as those of Elga’s account, and no worse than those of Lewis’ account. (shrink)

Our folk epistemology says that if someone knows that P and tells you that P, then, given the absence of defeaters, if you believe what they tell you, you will come to know that P as well. A speaker's knowledge that P is then, for the most part, enough for a hearer to come to know that P. But there are counterexamples to this principle: testimonial knowledge does not always transfer from the speaker to the hearer. Why should that be (...) so? Because testimonial knowledge arises through the flow of information--from conclusive grounds--from the speaker through the speaker's assertion to the hearer's state of comprehension as of the speaker's assertion. A speaker's belief can be based on conclusive grounds, but the speaker's assertion may fail to provide conclusive grounds to the hearer. Then the hearer won't acquire knowledge, even from a knowledgeable speaker. Knowledge from testimony then works more like knowledge through perception. But wait, you say, that can't be so because testimony involves free will but perception does not. The essay ends with a broadly Hume inspired reply to this objection. (shrink)

The dispute between realists about color and anti-realists is actually a dispute about the nature of color properties. The disputants do not disagree over what material objects are like. Rather, they disagree over whether any of the uncontroversial facts about material objects--their powers to cause visual experiences, their dispositions to reflect incident light, their atomic makeup, and so on--amount to their having colors. The disagreement is thus about which properties colors are and, in particular, whether colors are any of the (...) properties in a particular set that is acknowledged on both sides to exhaust the properties of material objects. In a previous paper we discussed at length one attempt to identify colors with particular properties of material objects--namely, with their dispositions to cause visual experiences. Here we shall discuss a different and perhaps more influential version of realism, which says that the colors of material objects are microphysical properties of their surfaces. We shall call this theory physicalism about color (physicalism, for short). In order to evaluate this theory, however, we shall first have to clarify some methodological issues. Our hope is that we can bring some further clarity to the question of color realism, whether or not we succeed in our critique of the physicalists' answer. (shrink)

Causal closure arguments against interactionist dualism are currently popular amongst physicalists. Such an argument appeals to some principles of the causal closure of the physical, together with certain other premises, to conclude that at least some mental events are identical with physical events. However, it is crucial to the success of any such argument that the physical causal closure principle to which it appeals is neither too strong nor too weak by certain standards. In this paper, it is argued that (...) various forms of naturalistic dualism, of an emergentist character, are consistent with the strongest physical causal closure principles that can plausibly be advocated.

Sceptical theists--e.g., William Alston and Michael Bergmann--have claimed that considerations concerning human cognitive limitations are alone sufficient to undermine evidential arguments from evil. We argue that, if the considerations deployed by sceptical theists are sufficient to undermine evidential arguments from evil, then those considerations are also sufficient to undermine inferences that play a crucial role in ordinary moral reasoning. If cogent, our argument suffices to discredit sceptical theist responses to evidential arguments from evil.

Philosophical accounts denying that temporal passage is an objective feature of reality face an explanatory challenge with respect to why it appears to us as though time passes. Recently, two solutions have surfaced. Cognitive illusionism claims that people experience the passage of time due to their belief that time passes. Cognitive error theory claims that we do not experience the passage of time, but hold the belief that we do, which we have acquired through making an inference from the prior (...) belief that time passes. These approaches suppose that belief and passage experience are explanatorily connected, and they depend on the claims that people who experience the passage of time or at least believe that they do also believe that time passes. To test these claims, we probed the beliefs of populations of individuals with depression and schizotypy, thus conditions that are strongly associated with alterations in temporal phenomenology. Depression was assessed with the Beck Depression Inventory (BDI) and schizotypy with the short Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE). While cognitive illusionism and inferentialist cognitive error theory would predict a strong association between BDI and O-LIFE scores and beliefs about time passage, our study found no such association. The experience of passage does not seem to be explanatorily connected to beliefs about the passage of time. (shrink)

Todas las reflexiones acerca del signo –convencionalismo-naturalismo, realismo- nominalismo, empirismo-racionalismo, concepción diádica-concepción triádica- se articulan en torno a las relaciones entre signo, pensamiento y realidad. Aunque todos coinciden en que un signo es "aliquid stat pro aliquo", esta antigua definición de carácter muy general adquiere implicaciones muy distintas según los presupuestos de cada autor y, todavía hoy, carecemos de un consenso en la definición de "signo".

This essay considers what it means to understand natural language and whether a computer running an artificial-intelligence program designed to understand natural language does in fact do so. It is argued that a certain kind of semantics is needed to understand natural language, that this kind of semantics is mere symbol manipulation (i.e., syntax), and that, hence, it is available to AI systems. Recent arguments by Searle and Dretske to the effect that computers cannot understand natural language are discussed, and (...) a prototype natural-language-understanding system is presented as an illustration.

Moral reasoning traditionally distinguishes two types of evil:moral (ME) and natural (NE). The standard view is that ME is the product of human agency and so includes phenomena such as war,torture and psychological cruelty; that NE is the product of nonhuman agency, and so includes natural disasters such as earthquakes, floods, disease and famine; and finally, that more complex cases are appropriately analysed as a combination of ME and NE. Recently, as a result of developments in autonomous agents in cyberspace, (...) a new class of interesting and important examples of hybrid evil has come to light. In this paper, it is called artificial evil (AE) and a case is made for considering it to complement ME and NE to produce a more adequate taxonomy. By isolating the features that have led to the appearance of AE, cyberspace is characterised as a self-contained environment that forms the essential component in any foundation of the emerging field of Computer Ethics (CE). It is argued that this goes someway towards providing a methodological explanation of why cyberspace is central to so many of CE's concerns; and it is shown how notions of good and evil can be formulated in cyberspace. Of considerable interest is how the propensity for an agent's action to be morally good or evil can be determined even in the absence of biologically sentient participants and thus allows artificial agents not only to perpetrate evil (and fort that matter good) but conversely to `receive' or `suffer from' it. The thesis defended is that the notion of entropy structure, which encapsulates human value judgement concerning cyberspace in a formal mathematical definition, is sufficient to achieve this purpose and, moreover, that the concept of AE can be determined formally, by mathematical methods. A consequence of this approach is that the debate on whether CE should be considered unique, and hence developed as a Macroethics, may be viewed, constructively,in an alternative manner. The case is made that whilst CE issues are not uncontroversially unique, they are sufficiently novel to render inadequate the approach of standard Macroethics such as Utilitarianism and Deontologism and hence to prompt the search for a robust ethical theory that can deal with them successfully. The name Information Ethics (IE) is proposed for that theory. Itis argued that the uniqueness of IE is justified by its being non-biologically biased and patient-oriented: IE is an Environmental Macroethics based on the concept of data entity rather than life. It follows that the novelty of CE issues such as AE can be appreciated properly because IE provides a new perspective (though not vice versa). In light of the discussion provided in this paper, it is concluded that Computer Ethics is worthy of independent study because it requires its own application-specific knowledge and is capable of supporting a methodological foundation, Information Ethics.

Nietzsche’s favourable comments about science and the senses have recently been taken as evidence of naturalism. Others focus on his falsification thesis: our beliefs are falsifying interpretations of reality. Clark argues that Nietzsche eventually rejects this thesis. This article utilizes the multiple ways of being science friendly in Nietzsche’s context by focussing on Mach’s neutral monism. Mach’s positivism is a natural development of neo-Kantian positions Nietzsche was reacting to. Section 15 of Beyond Good and Evil is crucial to Clark’s interpretation. (...) The presented interpretation makes better sense of this passage and shows that Nietzsche can accept both falsification and empiricism. (shrink)

Observers inspected normal, high quality color displays of everyday visual scenes while their eye movements were recorded. A large display change occurred each time an eye blink occurred. Display changes could either involve "Central Interest" or "Marginal Interest" locations, as determined from descriptions obtained from independent judges in a prior pilot experiment. Visual salience, as determined by luminance, color, and position of the Central and Marginal interest changes were equalized. -/- The results obtained were very similar to those obtained in (...) prior experiments showing failure to detect changes occurring simultaneously with saccades, flicker, or “mudsplashes” in the visual scene: Many changes were very hard to detect, and Marginal Interest changes were harder to detect than Central Interest changes. -/- Analysis of eye movements showed, as expected, that the probability of detecting a change depended on the eye’s distance from the change location. However a surprising finding was that both for Central and Marginal Interest changes, evenwhen observers were directly fixating the change locations (within 1 degree),more than 40% of the time they still failed to see the changes. It seems that looking at something does not guarantee you “ see” it. (shrink)

I argue that the theory of chance proposed by David Lewis has three problems: (i) it is time asymmetric in a manner incompatible with some of the chance theories of physics, (ii) it is incompatible with statistical mechanical chances, and (iii) the content of Lewis's Principal Principle depends on how admissibility is cashed out, but there is no agreement as to what admissible evidence should be. I proposes two modifications of Lewis's theory which resolve these difficulties. I conclude by tentatively (...) proposing a third modification of Lewis's theory, one which explains many of the common features shared by the chance theories of physics. (shrink)

The paper provides a critical review of the debate on the foundations of Computer Ethics (CE). Starting from a discussion of Moor’s classic interpretation of the need for CE caused by a policy and conceptual vacuum, five positions in the literature are identified and discussed: the “no resolution approach”, according to which CE can have no foundation; the professional approach, according to which CE is solely a professional ethics; the radical approach, according to which CE deals with absolutely unique issues, (...) in need of a unique approach; the conservative approach, according to which CE is only a particular applied ethics, discussing new species of traditional moral issues; and the innovative approach, according to which theoretical CE can expand the metaethical discourse with a substantially new perspective. In the course of the analysis, it is argued that, although CE issues are not uncontroversially unique, they are sufficiently novel to render inadequate the adoption of standard macroethics, such as Utilitarianism and Deontologism, as the foundation of CE and hence to prompt the search for a robust ethical theory. Information Ethics (IE) is proposed for that theory, as the satisfactory foundation for CE. IE is characterised as a biologically unbiased extension of environmental ethics, based on the concepts of information object/infosphere/entropy rather than life/ecosystem/pain. In light of the discussion provided in this paper, it is suggested that CE is worthy of independent study because it requires its own application-specific knowledge and is capable of supporting a methodological foundation, IE.

John Searle once said: "The Chinese room shows what we knew all along: syntax by itself is not sufficient for semantics. (Does anyone actually deny this point, I mean straight out? Is anyone actually willing to say, straight out, that they think that syntax, in the sense of formal symbols, is really the same as semantic content, in the sense of meanings, thought contents, understanding, etc.?)." I say: "Yes". Stuart C. Shapiro has said: "Does that make any sense? Yes: Everything (...) makes sense. The question is: What sense does it make?" This essay explores what sense it makes to say that syntax by itself is sufficient for semantics. (shrink)

Fictionalism has recently returned as a standard response to ontologically problematic domains. This article assesses moral fictionalism. It argues (i) that a correct understanding of the dialectical situation in contemporary metaethics shows that fictionalism is only an interesting new alternative if it can provide a new account of normative content: what is it that I am thinking or saying when I think or say that I ought to do something; and (ii) that fictionalism, qua fictionalism, does not provide us with (...) any new resources for providing such an account.

This article provides a philosophical response to the need for truth-telling about colonial history, focussing on the Australian context. The response consists in inviting philosophers and the public to engage in social-justice practices specified by a model called Distributed Truth-Telling (DTT), which integrates the historiography of injustices affecting Indigenous peoples with insights from social philosophy and cultural evolution theory. By contrast to official and large-scale truth commissions, distributed truth-telling is a set of non-elitist practices that weave three components: first, multisite, (...) multiformat, and multiscale inquiries into injustices; second, remedial imaginings and reasoning about moral repair and reconciliated futures; and finally, emotions suitable for motivating agents to cooperatively plan and implement moral revolutions. Distributed truth-telling can entrench virtuous feedback loops that contribute to moral revolutions. However, vicious feedback loops associated with collective denial and biases can impair distributed truth- telling and thwart moral revolutions. (shrink)

This article aims to shed light on the possible influence of the Kabbalah on Spinoza. To do this, I will analyze the role that the Kabbalist theoretical model may have had on the development of Spinozist philosophy, in order to understand both their convergences and their divergences. I will then clarify Spinoza's relationship to this theory, especially the Lurianic Kabbalah, and emphasize the importance of the notion of Tsimtsum (contraction of the Divine light).

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)

Moral discourse contains judgements of two prominent kinds. It contains deontic judgements about rightness and wrongness, obligation and duty, and what a person ought to do. As I understand them, these deontic judgements are normative: they express conclusions about the bearing of normative reasons on the actions and other responses that are available to us. And it contains evaluative judgements about goodness and badness. Prominent among these are the judgements that evaluate the quality of our responsiveness to morally relevant reasons. (...) We have a rich vocabulary for making such evaluations – our vocabulary of aretaic terms. Aretaic terms are those which can be used to attribute virtues: terms such as “kind”, “honest”, “fair”, “tolerant” and “reliable”. However, while they can be used to attribute virtues, they have other uses too; and they can be applied not only to persons but also to various states of persons, to actions and other responses, and to patterns of response. In this paper, I offer an account of the relationship between some of the principal uses of aretaic terms; and I show how a useful taxonomy of moral virtues can be generated from the thought that these are ways of being well oriented to morally relevant reasons.

The maturing of metaethics has been accompanied by widespread, but relatively unarticulated, discontent that mainstream metaethics is fundamentally on the wrong track. The malcontents we have in mind do not simply champion a competitor to the likes of noncognitivism or realism; they disapprove of the supposed presuppositions of the existing debate. Their aim is not to generate a new theory within metaethics, but to go beyond metaethics and to transcend the distinctions it draws between metaethics and normative ethics and between (...) cognitivism and non-cognitivism. In our experience, the differences with traditional metaethics go deep enough that it can feel as if two different paradigms are talking past each other. We attempt to bring clarity and focus to this rather inchoate debate by simultaneously articulating the general issues involved and engaging in a detailed case study of one of the prominent representatives of this discontent, Christine Korsgaard. We argue that Korsgaard fails to go beyond metaethics–indeed, fails even to provide a theory within metaethics. Our strategy for showing this is to argue that her claims are compatible with both cognitivism and non-cognitivism. We have argued elsewhere that her distinctive claims are compatible with realism. Here we focus on the crucial role that claims about agency and the will seem to play her in work and, according to our interpretation, in her attempts to go beyond mainstream metaethics. We show in detail that these claims are actually compatible with non-cognitivism. Though our discussion often focuses on her work in particular, it has clear implications for other attempts to obviate the debates of traditional metaethics. (shrink)

This article proposes an empirical approach to understanding the life of an organism that overcomes reductionist and dualist approaches. The approach is based on Immanuel Kant’s analysis of the cognitive conditions required for the recognition of an organism: the concept of teleology and the assumption of a formative power of self-generation. It is analyzed how these two criteria are applied in the cognition of a developing organism. Using the example of a developmental series of a plant leaf, an active and (...) relational process between observer and developing organism is shown, within which the teleology and self-generating power of the organism can be empirically observed through the mental faculties of understanding and will. Furthermore, it is emphasized that, according to Kant, even physical objects are not readily given, but are actively constituted through the unification of sense perceptions with concepts. This Kantian mode of objectification facilitates cognition of the physical properties of an organism. It can be supplemented with a participatory and co-constitutive mode of realization, in which the life of the organism (its teleologically organizing and self-generating power) can become an object of empirical research. Furthermore, it is argued that the participatory mode also facilitates an expanded conception of nature that allows for the existence of living beings within it. Finally, an analogy to Goethe’s approach to the living organism is highlighted. In summary, it is stated that to understand life, one must consciously participate in it. (shrink)

Our aim in this paper is to bring the woefully neglected literature on predictive modeling to bear on some central questions in the philosophy of science. The lesson of this literature is straightforward: For a very wide range of prediction problems, statistical prediction rules (SPRs), often rules that are very easy to implement, make predictions than are as reliable as, and typically more reliable than, human experts. We will argue that the success of SPRs forces us to reconsider our views (...) about what is involved in understanding, explanation, good reasoning, and about how we ought to do philosophy of science.

A variety of mental disorders—including ASD, ADHD, major depression, and anxiety disorder, among others—may directly impact what an agent notices or fails to notice. A recent debate has emphasised the potential significance of such “impairment-derived ignorance,” and argued that failure to account for certain compelling cases would seriously undermine theories which intend to establish the conditions for blameworthy ignorance. In this comment we argue, contra a recent challenge, that Quality of Will (QW) accounts are able to explain the normative significance (...) of impairment-derived ignorance. The plausible, ambivalent results QW accounts yield in difficult cases of impairment-derived ignorance further reveals the explanatory power of such accounts when it comes to blameworthy ignorance.

Haag’s theorem cries out for explanation and critical assessment: It sounds the alarm that something is (perhaps) not right in one of the standard ways of constructing interacting fields to be used in generating predictions for scattering experiments. Viewpoints as to the precise nature of the problem, the appropriate solution, and subsequently-called-for developments in areas of physics, mathematics, and philosophy differ widely. In this paper, we develop and deploy a conceptual framework for critically assessing these disparate responses to Haag’s theorem. (...) Doing so reveals the driving force of more general questions as to the nature and purpose of foundational work in physics. (shrink)

In discussions of practical reason we often encounter the view that a fact is a reason for an agent to act only if the fact is capable of moving the agent to act. This view figures centrally in many philosophical controversies, and while taken for granted by some, it is vigorously disputed by others. In this essay I show that if the disputed position is correctly interpreted, it is well armored against stock objections and implied by a premise that is (...) not only plausible, but generally accepted by the position's critics.

This article outlines an epistemological perspective to understand the organism as a temporally changing whole. To analyze the mental faculties involved, the organism’s development and persisting existence is differentiated into four interdependent aspects: descent, future existence, persistent species, and environmentally adapted physical appearance. It is outlined that these aspects are recognized by comparative memory, concept-guided anticipation, conceptual thinking, and sensory perception, respectively. Furthermore, it is pointed out that these aspects correspond to the famous four Aristotelian “causes” or principles of explanation. (...) The descent of an organism corresponds to Aristotle’s efficient principle (“where does it come from?”), its future existence to the final principle (“what is if for?”), its physical structure to the material principle (“out of what is it?”) and its persistent species to the formal principle (“what is it?”). Aristotle regarded the unity of the efficient, formal and final principle as the ontological cause of the organism and called it the “soul” (psyche), while the material principle can be understood to represent its “body” (soma). I suggest that Aristotle’s “soul” corresponds to three of the four mental faculties required for cognition of a self-maintaining organism. I argue that in a Kantian perspective, the Aristotelian “soul” represents the condition for recognizing an organism at all. Therefore, the Aristotelian principle of life becomes intelligible and even empirically observable through the inner sense. In summary, I suggest that the four aspects of the organism described here can be viewed as the general, epistemological and ontological principle of the organism, the Bio-Logos. (shrink)

Betrayal trauma theory suggests that psychogenic amnesia is an adaptive response to childhood abuse. When a parent or other powerful figure violates a fundamental ethic of human relationships, victims may need to remain unaware of the trauma not to reduce suffering but rather to promote survival. Amnesia enables the child to maintain an attachment with a figure vital to survival, development, and thriving. Analysis of evolutionary pressures, mental modules, social cognitions, and developmental needs suggests that the degree to which the (...) most fundamental human ethics are violated can influence the nature, form, and processes of trauma and responses to trauma.

The biological sciences study (bio)complex living systems. Research directed at the mechanistic explanation of the "live" state truly requires a pluralist research program, i.e. BioComplexity research. The program should apply multiple intra-level and inter-level theories and methodologies. We substantiate this thesis with analysis of BioComplexity: metabolic and modular control analysis of metabolic pathways, emergence of oscillations, and the analysis of the functioning of glycolysis.

David Lewis is widely known for maintaining the bizarre thesis known as genuine modal realism (hereafter, modal realism). He argued for modal realism on grounds of serviceability in On the Plurality of Worlds. However, earlier in Counterfactuals, he proposed a different kind of argument: from talk of ways things might be to possible worlds. In this paper, I examine the evolution of the latter argument in Lewis’s thought and evaluate its place in his overall case for modal realism, especially in (...) light of the alternative theory of modality known as magical ersatzism. I argue that Lewis turns the argument on its head in his critique of magical ersatzism, but that his later commitment to Ramseyan humility subjects him to a similar criticism. Therefore, the argument is, ultimately, a poisoned pawn for Lewis. (shrink)

In this article, I confront Jessica Flanigan’s recent attempt to show not merely that women have a right to commit prenatal injury, but also that women who act on this right are praiseworthy and should not be criticized for this injury. I show that Flanigan’s arguments do not work, and I establish presumptive grounds against any such right—namely, prenatal injury, by definition, involves intentional or negligent harm and, as such, may be subsumed under a wider class of actions that are (...) presumptively wrong.

We are subject to many different norms telling us how to act, from moral norms to etiquette rules and the law. While some norms may simply be ignored, we live under the impression that others matter for what we ought to do. How can we make sense of this normative authority some norms have? Does it fit into our naturalist worldview? Many philosophers claim it does not. Normativity is conceived to be distinct from ordinary natural properties, making it mysterious. The (...) mystery fuels a radical yet prominent scepticism about the existence of normative properties: if they are too strange to actually exist, there is nothing we ought to do. Some take this to mean, moreover, that nothing is morally right or wrong. We must critically examine the ideas behind these theories, which put both morality and normativity in general on the line. -/- The aim of this thesis is to unravel the mystery of normativity. It uncovers and objects to the influential non-natural conception of it, arguing that we can capture normativity with natural properties. In particular, it explores how the authority of norms can be explained by the commitments of the people subject to them. In connection to this, it challenges the conceptual claim behind the view that all moral judgements are mistaken. Finally, it reveals that treating morality as a mere fiction has revolutionary practical implications. This emphasises the importance of the overall conclusion: we need not conceive of either moral or normative properties as too mysterious to exist. (shrink)

Following Nancy Cartwright and others, I suggest that most (if not all) theories incorporate, or depend on, one or more idealizing assumptions. I then argue that such theories ought to be regimented as counterfactuals, the antecedents of which are simplifying assumptions. If this account of the logic form of theories is granted, then a serious problem arises for Bayesians concerning the prior probabilities of theories that have counterfactual form. If no such probabilities can be assigned, the the posterior probabilities will (...) be undefined, as the latter are defined in terms of the former. I argue here that the most plausible attempts to address the problem of probabilities of conditionals fail to help Bayesians, and, hence, that Bayesians are faced with a new problem. In so far as these proposed solutions fail, I argue that Bayesians must give up Bayesianism or accept the counterintuitive view that no theories that incorporate any idealizations have ever really been confirmed to any extent whatsoever. Moreover, as it appears that the latter horn of this dilemma is highly implausible, we are left with the conclusion that Bayesianism should be rejected, at least as it stands. (shrink)

Consciousness and evolution are complex phenomena. It is sometimes thought that if adaptation explanations for some varieties of consciousness, say, conscious visual perception, can be had, then we may be reassured that at least those kinds of consciousness are not epiphenomena. But what if other varieties of consciousness, for example, dreams, are not adaptations? We sort out the connections among evolution, adaptation, and epiphenomenalism in order to show that the consequences for the nature and causal efficacy of consciousness are not (...) as dire as has sometimes been supposed.

Property-identical divine-command theory (PDCT) is the view that being obligatory is identical to being commanded by God in just the way that being water is identical to being H2O. If these identity statements are true, then they express necessary a posteriori truths. PDCT has been defended in Robert M. Adams (1987) and William Alston (1990). More recently Mark C. Murphy (2002) has argued that property-identical divine-command theory is inconsistent with two well-known and well-received theses: the free-command thesis and the supervenience (...) thesis. I show that Murphy's argument is vitiated by mistaken assumptions about the substitutivity of metaphysical identicals in contexts of supervenience. The free-command thesis and the supervenience thesis therefore pose no serious threat to PDCT. (Published Online August 11 2004). (shrink)

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

I argue for the thesis (UL) that there are certain logical abilities that any rational creature must have. Opposition to UL comes from naturalized epistemologists who hold that it is a purely empirical question which logical abilities a rational creature has. I provide arguments that any creatures meeting certain conditions—plausible necessary conditions on rationality—must have certain specific logical concepts and be able to use them in certain specific ways. For example, I argue that any creature able to grasp theories must (...) have a concept of conjunction subject to the usual introduction and elimination rules. I also deal with disjunction, conditionality and negation. Finally, I put UL to work in showing how it could be used to define a notion of logical obviousness that would be well suited to certain contexts—e.g. radical translation and epistemic logic—in which a concept of obviousness is often invoked.

This article is an explication and defense of Kant’s view that ‘imagination is a necessary ingredient of perception itself’ (Critique of Pure Reason, A120, fn.). Imagination comes into perception at a far more basic level than Strawson allows, and it is required for the constitution of intuitions (= sense experiences) out of sense impressions. It also plays an important part in explaining how it is possible for intuitions to have intentional contents. These functions do not involve the application of contents, (...) and I offer a schematic account of how they arise from preconceptual synthesis. (shrink)
