It has generally been assumed that rapid visual search is based on simple features and that spatial relations between features are irrelevant for this task. Seven experiments involving search for line drawings contradict this assumption; a major determinant of search is the presence of line junctions. Arrow- and Y-junctions were detected rapidly in isolation and when they were embedded in drawings of rectangular polyhedra. Search for T-junctions was considerably slower. Drawings containing T-junctions often gave rise to very slow search even (...) when distinguishing arrow- or Y-junctions were present. This sensitivity to line relations suggests that preattentive processes can extract 3-dimensional orientation from line drawings. A computational model is outlined for how this may be accomplished in early human vision. (shrink)

The task of visual search is to determine as rapidly as possible whether a target item is present or absent in a display. Rapidly detected items are thought to contain features that correspond to primitive elements in the human visual system. In previous theories, it has been assumed that visual search is based on simple two-dimensional features in the image. However, visual search also has access to another level of representation, one that describes properties in the corresponding three-dimensional scene. Among (...) these properties are three dimensionality and the direction of lighting, but not viewing direction. These findings imply that the parallel processes of early vision are much more sophisticated than previously assumed. (shrink)

Previous theories of early vision have assumed that visual search is based on simple two-dimensional aspects of an image, such as the orientation of edges and lines. It is shown here that search can also be based on three-dimensional orientation of objects in the corresponding scene, provided that these objects are simple convex blocks. Direct comparison shows that image-based and scene-based orientation are similar in their ability to facilitate search. These findings support the hypothesis that scene-based properties are represented at (...) preattentive levels in early vision. (shrink)

Advances in neuroscience implicate reentrant signaling as the predominant form of communication between brain areas. This principle was used in a series of masking experiments that defy explanation by feed-forward theories. The masking occurs when a brief display of target plus mask is continued with the mask alone. Two masking processes were found: an early process affected by physical factors such as adapting luminance and a later process affected by attentional factors such as set size. This later process is called (...) masking by object substitution, because it occurs whenever there is a mismatch between the reentrant visual representation and the ongoing lower level activity. Iterative reentrant processing was formalized in a computational model that provides an excellent fit to the data. The model provides a more comprehensive account of all forms of visual masking than do the long-held feed-forward views based on inhibitory contour interactions. (shrink)

My argument proceeds in two stages. In §I, I sum up the intuitions of a popular argument for 'satisfaction accounts' of Purgatory that I label, TAP. I then offer an argument, taken from a few standard orthodox Christian beliefs and one axiom of Christian theology, to so show that TAP is unsound. In the same section, I entertain some plausible responses to my argument that are prima facie consistent with these beliefs and axiom. I find these responses wanting. In §II, (...) I offer a sorites problem for TAP, given the orthodox Christian understanding of Christ’s parousia, showing that TAP and the intuitions driving it are faulty. To attempt something of a corrective, I end by offering some modest theological suggestions for thinking through “the logic of total transformation.”. (shrink)

The doctrine of the resurrection says that God will resurrect the body that lived and died on earth—that the post-mortem body will be numerically identical to the pre-mortem body. After exegetically supporting this claim, and defending it from a recent objection, we ask: supposing that the doctrine of the resurrection is true, what are the implications for the mind-body relation? Why would God resurrect the body that lived and died on earth? We compare three accounts of the mind-body relation that (...) have been applied to the doctrine of the resurrection: substance dualism, constitutionalism, and animalism. We argue that animalism offers a superior explanation for the necessity of the resurrection: since human persons just are their bodies, life after death requires resurrection of one’s body. We conclude that those endorsing the doctrine of the resurrection should be animalists. (shrink)

We show that early vision can use monocular cues to rapidly complete partially-occluded objects. Visual search for easily detected fragments becomes difficult when the completed shape is similar to others in the display; conversely, search for fragments that are difficult to detect becomes easy when the completed shape is distinctive. Results indicate that completion occurs via the occlusion-triggered removal of occlusion edges and linking of associated regions. We fail to find evidence for a visible filling-in of contours or surfaces, but (...) do find evidence for a "functional" filling-in that prevents the constituent fragments from being rapidly accessed. As such, it is only the completed structures—and not the fragments themselves—that serve as the basis for rapid recognition. (shrink)

Experiments are presented showing that visual search for Mueller-Lyer (ML) stimuli is based on complete configurations, rather than component segments. Segments easily detected in isolation were difficult to detect when embedded in a configuration, indicating preemption by low-level groups. This preemption—which caused stimulus components to become inaccessible to rapid search—was an all-or-nothing effect, and so could serve as a powerful test of grouping. It is shown that these effects are unlikely to be due to blurring by simple spatial filters at (...) early visual levels. It is proposed instead that they are due to more sophisticated processes that rapidly bind contour fragments into spatially-extended assemblies. These results support the view that rapid visual search cannot access the primitives formed at the earliest stages of visual processing; rather, it can access only higher-level, more ecologically-relevant structures. (shrink)

A modified visual search task demonstrates that humans are very good at resuming a search after it has been momentarily interrupted. This is shown by exceptionally rapid response time to a display that reappears after a brief interruption, even when an entirely different visual display is seen during the interruption and two different visual searches are performed simultaneously. This rapid resumption depends on the stability of the visual scene and is not due to display or response anticipations. These results are (...) consistent with the existence of an iterative hypothesis-testing mechanism that compares information stored in short-term memory (the perceptual hypothesis) with information about the display (the sensory pattern). In this view, rapid resumption occurs because a hypothesis based on a previous glance of the scene can be tested very rapidly in a subsequent glance, given that the initial hypothesis-generation step has already been performed.

The premise of biological modularity is an ontological claim that appears to come out of practice. We understand that the biological world is modular because we can manipulate different parts of organisms in ways that would only work if there were discrete parts that were interchangeable. This is the foundation of the BioBrick assembly method widely used in synthetic biology. It is one of a number of methods that allows practitioners to construct and reconstruct biological pathways and devices using DNA (...) libraries of standardized parts with known functions. In this paper, we investigate how the practice of synthetic biology reconfigures biological understanding of the key concepts of modularity and evolvability. We illustrate how this practice approach takes engineering knowledge and uses it to try to understand biological organization by showing how the construction of functional parts and processes can be used in synthetic experimental evolution. We introduce a new approach within synthetic biology that uses the premise of a parts-based ontology together with that of organismal self-organization to optimize orthogonal metabolic pathways in E. coli. We then use this and other examples to help characterize semisynthetic categories of modularity, parthood, and evolvability within the discipline. (shrink)

This is the introduction to the Routledge Companion to Thought Experiments.

I want to suggest that it would be bad if compatibilism were true, and that this gives us good reason to think that it isn't. This is, you might think, an outlandish argument, and the considerable burden of this paper is to convince you otherwise. There are two key elements at stake in this argument. The first is that it would be ‐ in a distinctive sense to be explained ‐ bad if compatibilism were true. The thought here is that (...) compatibilism ultimately presents us with a picture on which, in principle, powerful manipulators can effectively guarantee that finite moral agents should become blameworthy. To my mind, this isn't just false ‐ though I think that it is ‐ it is also such that it would be bad (unfortunate, undesirable…) if it were true. The second is that the fact that it would be ‐ in this sense ‐ bad if true gives us reason to think that it isn't. It may be bad that there is no afterlife. But that, in itself, hardly gives us reason to think that there is an afterlife. That is true, but ‐ as others before me have suggested ‐ when the object of the relevant badness is morality itself, the inference seems secure. A more general aim of the paper is to investigate the nature of this very form of argument in itself, and I compare my argument (inter alia) to a recent argument from Sayre–McCord against the possibility of genuine moral dilemmas.

The principle of Conditional Excluded Middle has been a matter of longstanding controversy in both semantics and metaphysics. The principle suggests (among other things) that for any coin that isn't flipped, there is a fact of the matter about how it would have landed if it had been flipped: either it would have landed heads, or it would have landed tails. This view has gained support from linguistic evidence indicating that ‘would’ commutes with negation (e.g., ‘not: if A, would C’ (...) is equivalent to ‘if A, would not C’). There is, however, a long list of operators that similarly appear to commute with negation, even though the corresponding excluded middle principles are indefensible. We suggest that the data supporting Conditional Excluded Middle is best explained as a pragmatic effect. (shrink)

At least since Aristotle’s famous 'sea-battle' passages in On Interpretation 9, some substantial minority of philosophers has been attracted to the doctrine of the open future--the doctrine that future contingent statements are not true. But, prima facie, such views seem inconsistent with the following intuition: if something has happened, then (looking back) it was the case that it would happen. How can it be that, looking forwards, it isn’t true that there will be a sea battle, while also being true (...) that, looking backwards, it was the case that there would be a sea battle? This tension forms, in large part, what might be called the problem of future contingents. A dominant trend in temporal logic and semantic theorizing about future contingents seeks to validate both intuitions. Theorists in this tradition--including some interpretations of Aristotle, but paradigmatically, Thomason (1970), as well as more recent developments in Belnap, et. al (2001) and MacFarlane (2003, 2014)--have argued that the apparent tension between the intuitions is in fact merely apparent. In short, such theorists seek to maintain both of the following two theses: (i) the open future: Future contingents are not true, and (ii) retro-closure: From the fact that something is true, it follows that it was the case that it would be true. It is well-known that reflection on the problem of future contingents has in many ways been inspired by importantly parallel issues regarding divine foreknowledge and indeterminism. In this paper, we take up this perspective, and ask what accepting both the open future and retro-closure predicts about omniscience. When we theorize about a perfect knower, we are theorizing about what an ideal agent ought to believe. Our contention is that there isn’t an acceptable view of ideally rational belief given the assumptions of the open future and retro-closure, and thus this casts doubt on the conjunction of those assumptions.

I provide a manipulation-style argument against classical compatibilism—the claim that freedom to do otherwise is consistent with determinism. My question is simple: if Diana really gave Ernie free will, why isn't she worried that he won't use it precisely as she would like? Diana's non-nervousness, I argue, indicates Ernie's non-freedom. Arguably, the intuition that Ernie lacks freedom to do otherwise is stronger than the direct intuition that he is simply not responsible; this result highlights the importance of the denial of (...) the principle of alternative possibilities for compatibilist theories of responsibility. Along the way, I clarify the dialectical role and structure of “manipulation arguments”, and compare the manipulation argument I develop with the more familiar Consequence Argument. I contend that the two arguments are importantly mutually supporting and reinforcing. The result: classical compatibilists should be nervous—and if PAP is true, all compatibilists should be nervous. (shrink)

Various philosophers have long since been attracted to the doctrine that future contingent propositions systematically fail to be true—what is sometimes called the doctrine of the open future. However, open futurists have always struggled to articulate how their view interacts with standard principles of classical logic—most notably, with the Law of Excluded Middle. For consider the following two claims: Trump will be impeached tomorrow; Trump will not be impeached tomorrow. According to the kind of open futurist at issue, both of (...) these claims may well fail to be true. According to many, however, the disjunction of these claims can be represented as p ∨ ~p—that is, as an instance of LEM. In this essay, however, I wish to defend the view that the disjunction these claims cannot be represented as an instance of p ∨ ~p. And this is for the following reason: the latter claim is not, in fact, the strict negation of the former. More particularly, there is an important semantic distinction between the strict negation of the first claim [~] and the latter claim. However, the viability of this approach has been denied by Thomason, and more recently by MacFarlane and Cariani and Santorio, the latter of whom call the denial of the given semantic distinction “scopelessness”. According to these authors, that is, will is “scopeless” with respect to negation; whereas there is perhaps a syntactic distinction between ‘~Will p’ and ‘Will ~p’, there is no corresponding semantic distinction. And if this is so, the approach in question fails. In this paper, then, I criticize the claim that will is “scopeless” with respect to negation. I argue that will is a so-called “neg-raising” predicate—and that, in this light, we can see that the requisite scope distinctions aren’t missing, but are simply being masked. The result: a under-appreciated solution to the problem of future contingents that sees and as contraries, not contradictories. (shrink)

The plane was going to crash, but it didn't. Johnny was going to bleed to death, but he didn't. Geach sees here a changing future. In this paper, I develop Geach's primary argument for the (almost universally rejected) thesis that the future is mutable (an argument from the nature of prevention), respond to the most serious objections such a view faces, and consider how Geach's view bears on traditional debates concerning divine foreknowledge and human freedom. As I hope to show, (...) Geach's view constitutes a radically new view on the logic of future contingents, and deserves the status of a theoretical contender in these debates. (shrink)

This Introduction has three sections, on "logical fatalism," "theological fatalism," and the problem of future contingents, respectively. In the first two sections, we focus on the crucial idea of "dependence" and the role it plays it fatalistic arguments. Arguably, the primary response to the problems of logical and theological fatalism invokes the claim that the relevant past truths or divine beliefs depend on what we do, and therefore needn't be held fixed when evaluating what we can do. We call the (...) sort of dependence needed for this response to be successful "dependence with a capital 'd'": Dependence. We consider different accounts of Dependence, especially the account implicit in the so-called "Ockhamist" response to the fatalistic arguments. Finally, we present the problem of future contingents: what could "ground" truths about the undetermined future? On the other hand, how could all such propositions fail to be true? (shrink)

Everyone agrees that we can’t change the past. But what about the future? Though the thought that we can change the future is familiar from popular discourse, it enjoys virtually no support from philosophers, contemporary or otherwise. In this paper, I argue that the thesis that the future is mutable has far more going for it than anyone has yet realized. The view, I hope to show, gains support from the nature of prevention, can provide a new way of responding (...) to arguments for fatalism, can account for the utility of total knowledge of the future, and can help in providing an account of the semantics of the English progressive. On the view developed, the future is mutable in the following sense: perhaps, once, it was true that you would never come to read a paper defending the mutability of the future. And then the future changed. And now you will. (shrink)

I bet you don’t practice your philosophical intuitions. What’s your excuse? If you think philosophical training improves the reliability of philosophical intuitions, then practicing intuitions should improve them even further. I argue that philosophers’ reluctance to practice their intuitions highlights a tension in the way that they think about the role of intuitions in philosophy.

According to the dogmatism puzzle, for any S and any p, if S knows that p, then she’s entitled to be dogmatic about p, and so disregard any evidence against p, for she knows that (or is in a position to know that) that evidence is misleading. But this seems clearly problematically dogmatic. The standard solution to the dogmatism puzzle involves appealing to the view that acquiring new evidence (even misleading evidence) can undermine one’s knowledge that p. That’s why one (...) can’t rightly disregard any future evidence against p. This solution to the dogmatism puzzle has come to be called ‘the defeat solution’. Maria Lasonen-Aarnio has recently argued, however, that the defeat solution leaves unsolved a partial defeat version of the dogmatism puzzle, where some subject acquires weak misleading evidence against p, but, since it is weak, it doesn’t rob her of knowledge that p. Lasonen-Aarnio argues that solving this partial defeat version of the dogmatism puzzle requires those who endorse the defeasibility of knowledge to either go dogmatist or reject an extremely plausible principle that she calls ‘Entitlement’ (roughly, for any S and any e, if S knows that evidence e is misleading, then S can rightly disregard e). In this paper, however, I argue that defeasibilists face no such challenge from any version of the dogmatism puzzle, since the dogmatism puzzle, in both its original and partial defeat form, rests on an assumption that we have very good reason to think is mistaken. Specifically, the assumption that, for any S and any p, if S knows that p, then S knows (or is in a position to know) that any evidence against p is misleading. I further argue that rejecting this assumption also yields a neat solution to the dogmatism puzzle involving intention originally proposed by Saul Kripke and recently adapted by R.E. Fraser.

In this review, we describe some of the central philosophical issues facing origins-of-life research and provide a targeted history of the developments that have led to the multidisciplinary field of origins-of-life studies. We outline these issues and developments to guide researchers and students from all fields. With respect to philosophy, we provide brief summaries of debates with respect to (1) definitions (or theories) of life, what life is and how research should be conducted in the absence of an accepted theory (...) of life, (2) the distinctions between synthetic, historical, and universal projects in origins-of-life studies, issues with strategies for inferring the origins of life, such as (3) the nature of the first living entities (the “bottom up” approach) and (4) how to infer the nature of the last universal common ancestor (the “top down” approach), and (5) the status of origins of life as a science. Each of these debates influences the others. Although there are clusters of researchers that agree on some answers to these issues, each of these debates is still open. With respect to history, we outline several independent paths that have led to some of the approaches now prevalent in origins-of-life studies. These include one path from early views of life through the scientific revolutions brought about by Linnaeus (von Linn.), Wöhler, Miller, and others. In this approach, new theories, tools, and evidence guide new thoughts about the nature of life and its origin.We also describe another family of paths motivated by a” circularity” approach to life, which is guided by such thinkers as Maturana & Varela, Gánti, Rosen, and others. These views echo ideas developed by Kant and Aristotle, though they do so using modern science in ways that produce exciting avenues of investigation. By exploring the history of these ideas, we can see how many of the issues that currently interest us have been guided by the contexts in which the ideas were developed. The disciplinary backgrounds of each of these scholars has influenced the questions they sought to answer, the experiments they envisioned, and the kinds of data they collected. We conclude by encouraging scientists and scholars in the humanities and social sciences to explore ways in which they can interact to provide a deeper understanding of the conceptual assumptions, structure, and history of origins-of-life research. This may be useful to help frame future research agendas and bring awareness to the multifaceted issues facing this challenging scientific question. (shrink)

“Physical premotion” is a concept associated with Baroque Catholic theological debates concerning grace and freedom. In this paper, I present an argument that the entities identified in this debate, physical premotions, are necessary for any classical theist’s account of divine causality. A “classical theist” is a theist who holds both that God is simple, that is, without inhering properties, and that humans and God are both free in the incompatibilist sense. In fact, not only does the acceptance of physical premotions (...) not entail determinism, physical premotions are the only way for classical theists to preserve the aforementioned two commitments. Nevertheless, the theory of premotions cannot help theologians resolve questions of how God causes human free acts without violating their freedom. (shrink)

This paper defends the usefulness of the concept of philosophical progress and the common assumption that philosophy and science aim to make the same, or a comparable, kind of progress. It does so by responding to Yafeng Shan's (2022) arguments that the wealth of research on scientific progress is not applicable or useful to philosophy, and that philosophy doesn't need a concept of progress at all. It is ultimately argued that while Shan's arguments are not successful, they reveal the way (...) forward in developing accounts of philosophical progress. (shrink)

In this chapter I argue that writers on metaphor have misunderstood Aristotle on metaphor. Aristotle is not an elitist about metaphor and does not consider metaphors to be merely ornamental. Rather, Aristotle believes that metaphors are ubiquitous and believes that people can express themselves in a clearer and more attractive way through the use of metaphors and that people learn and understand things better through metaphor. He also distinguishes between the use of metaphor and the coinage of metaphor, and believes (...) that the ability to coin marvelous new metaphors is a form of literary genius, and he provided an entirely natural origin of metaphor coinage.

The COVID-19 has had a significant impact on people's lives and business operations around the world. Additionally, it has an effect on the purchasing habits of the Filipino youth. The researchers employed a qualitative research technique in this study to determine changes in the purchasing behavior of Filipino youth, specifically young adults aged 18-25 in Metro Manila. Our findings indicate that young Filipinos have become significantly interested in digital commerce in the country, a trend that has been growing consistently since (...) the pandemic started. Since the pandemic began, they have valued the effeciency and convenience of making purchases thru online platforms. As a result, many individuals chose to support local businesses by downloading apps or visiting websites that enable them to purchase online. According to the findings of the study, many of the respondents said that they prioritized buying necessities over wants. Because money was tight due to the lockdowns, which caused the majority of Filipinos to lose their jobs or stop working, Filipinos were careful with their expenditures throughout the pandemic. We the researchers concluded based on the responses we got thru our online interviews, that the pandemic indeed impacted the buying behavior of the Filipino youth. (shrink)

Let serious propositional contingentism (SPC) be the package of views which consists in (i) the thesis that propositions expressed by sentences featuring terms depend, for their existence, on the existence of the referents of those terms, (ii) serious actualism—the view that it is impossible for an object to exemplify a property and not exist—and (iii) contingentism—the view that it is at least possible that some thing might not have been something. SPC is popular and compelling. But what should we say (...) about possible worlds, if we accept SPC? Here, I first show that a natural view of possible worlds, well-represented in the literature, in conjunction with SPC is inadequate. Though I note various alternative ways of thinking about possible worlds in response to the first problem, I then outline a second more general problem—a master argument—which generally shows that any account of possible worlds meeting very minimal requirements will be inconsistent with compelling claims about _mere possibilia_ which the serious propositional contingentist should accept.

In some cases, a group of people can bring about a morally bad outcome despite each person’s individual act making no difference with respect to bringing that outcome about. Since each person’s act makes no difference, it seems the effects of the act cannot provide a reason not to perform it. This is problematic, because if each person acts in accordance with their reasons, each will presumably perform the act—and thus, the bad outcome will be brought about. Recently, Julia Nefsky (...) has argued that this problem is solved by rejecting the assumption that if an act makes no difference with respect to an outcome, then the act cannot do anything non-superfluous toward bringing that outcome about. Nefsky suggests that, even if an act makes no difference, the act may nevertheless help: it may make a non-superfluous causal contribution. If this is right, it means that the potential effects of an act may give us a reason to perform the act, even if the act wouldn’t make a difference. In this paper, I offer some reasons to be wary of Nefsky’s approach. I first argue that her account generates problematic results in a certain range of cases, and thus that we may have no reason to help in any case. I then argue that, even if we do sometimes have a reason to act when it seems we cannot make a difference, this reason cannot be the one that Nefsky identifies. (shrink)

Various studies have reported that moral intuitions about the permissibility of acts are subject to framing effects. This paper reports the results of a series of experiments which further examine the susceptibility of moral intuitions to framing effects. The main aim was to test recent speculation that intuitions about the moral relevance of certain properties of cases might be relatively resistent to framing effects. If correct, this would provide a certain type of moral intuitionist with the resources to resist challenges (...) to the reliability of moral intuitions based on such framing effects. And, fortunately for such intuitionists, although the results can’t be used to mount a strident defence of intuitionism, the results do serve to shift the burden of proof onto those who would claim that intuitions about moral relevance are problematically sensitive to framing effects.

On a number of occasions in Plato’s dialogues Socrates appears to disavow all knowledge. At Apology 21d, for example, Socrates says of one of his interlocutors: ‘He, having no knowledge, thinks he knows something, while I, having none, don’t think I have any,’ On other occasions, however, Socrates does claim to know some things: ‘It is not a mere guess to say that knowledge and right opinion are different. There are few things I would claim to know, but that at (...) least is among them, whatever else is’ (Meno 98b). Gregory Vlastos has sought to show that Socrates did not contradict himself but operated on the basis of two different senses of ‘know’: ‘know in the sense of having certainty’ and ‘know on the basis of elenctic examination.’ I argue against Vlastos’ interpretation and propose instead that Socrates claimed to know various things, but not the essential nature of virtue.

Do philosophers use intuitions? Should philosophers use intuitions? Can philosophical methods (where intuitions are concerned) be improved upon? In order to answer these questions we need to have some idea of how we should go about answering them. I defend a way of going about methodology of intuitions: a metamethodology. I claim the following: (i) we should approach methodological questions about intuitions with a thin conception of intuitions in mind; (ii) we should carve intuitions finely; and, (iii) we should carve (...) to a grain to which we are sensitive in our everyday philosophising. The reason is that, unless we do so, we don’t get what we want from philosophical methodology. I argue that what we want is information that will aid us in formulating practical advice concerning how to do philosophy responsibly/well/better. (shrink)

Why are natural theories pre-well-ordered by consistency strength? In previous work, an approach to this question was proposed. This approach was inspired by Martin's Conjecture, one of the most prominent conjectures in recursion theory. Fixing a reasonable subsystem $T$ of arithmetic, the goal was to classify the recursive functions that are monotone with respect to the Lindenbaum algebra of $T$. According to an optimistic conjecture, roughly, every such function must be equivalent to an iterate $\mathsf{Con}_T^\alpha$ of the consistency operator ``in (...) the limit'' within the ultrafilter of sentences that are true in the standard model. In previous work the author established the first case of this optimistic conjecture; roughly, every recursive monotone function is either as weak as the identity operator in the limit or as strong as $\mathsf{Con}_T$ in the limit. Yet in this note we prove that this optimistic conjecture fails already at the next step; there are recursive monotone functions that are neither as weak as $\mathsf{Con}_T$ in the limit nor as strong as $\mathsf{Con}_T^2$ in the limit. In fact, for every $\alpha$, we produce a function that is cofinally equivalent to $\mathsf{Con}^\alpha_T$ yet cofinally equivalent to $\mathsf{Con}_T$. (shrink)

It is well known that the following features hold of AR + T under the strong Kleene scheme, regardless of the way the language is Gödel numbered: 1. There exist sentences that are neither paradoxical nor grounded. 2. There are 2ℵ0 fixed points. 3. In the minimal fixed point the weakly definable sets (i.e., sets definable as {n∣ A(n) is true in the minimal fixed point where A(x) is a formula of AR + T) are precisely the Π1 1 sets. (...) 4. In the minimal fixed point the totally defined sets (sets weakly defined by formulae all of whose instances are true or false) are precisely the ▵1 1 sets. 5. The closure ordinal for Kripke's construction of the minimal fixed point is ωCK 1. In contrast, we show that under the weak Kleene scheme, depending on the way the Gödel numbering is chosen: 1. There may or may not exist nonparadoxical, ungrounded sentences. 2. The number of fixed points may be any positive finite number, ℵ0, or 2ℵ0 . 3. In the minimal fixed point, the sets that are weakly definable may range from a subclass of the sets 1-1 reducible to the truth set of AR to the Π1 1 sets, including intermediate cases. 4. Similarly, the totally definable sets in the minimal fixed point range from precisely the arithmetical sets up to precisely the ▵1 1 sets. 5. The closure ordinal for the construction of the minimal fixed point may be ω, ωCK 1, or any successor limit ordinal in between. In addition we suggest how one may supplement AR + T with a function symbol interpreted by a certain primitive recursive function so that, irrespective of the choice of the Godel numbering, the resulting language based on the weak Kleene scheme has the five features noted above for the strong Kleene language.

A reorientation is needed in methodological debate about the role of intuitions in philosophy. Methodological debate has lost sight of the reason why it makes sense to focus on questions about intuitions when thinking about the methods or epistemology of philosophy. The problem is an approach to methodology that focuses almost exclusively on questions about some evidential role that intuitions may or may not play in philosophers’ arguments. A new approach is needed. Approaching methodological questions about the role of intuitions (...) in philosophy with an abductive model of philosophical inquiry in mind will help ensure the debate doesn't lose sight of what motivates the debate.

In ‘Burnt Norton’, the first of his ‘four quartets’, Eliot selected two Heraclitus’ fragments as epigraphs. In quoting fragment B 60 (‘the way up and the way down are one and the same’) he was reminding his readers that entrance into a spiritual life calls for both engagement and withdrawal, for both descending and ascending. And in quoting B 2 he reaffirmed Heraclitus’ conviction that most people fail to recognize the truth even when it is directly presented to them. In (...) his later Cocktail Party Eliot revisited these themes by converting a depiction of a failed social gathering into an exploration of forms of authenticity. He also exploited the dual nature of the Heraclitean daimôn—as external overseer and as the soul which lies within each person—to transform an account of a gathering of friends and strangers into an extended reflection on the conflicts lying within each human soul.

• It would be a moral disgrace for God (if he existed) to allow the many evils in the world, in the same way it would be for a parent to allow a nursery to be infested with criminals who abused the children. • There is a contradiction in asserting all three of the propositions: God is perfectly good; God is perfectly powerful; evil exists (since if God wanted to remove the evils and could, he would). • The religious believer (...) has no hope of getting away with excuses that evil is not as bad as it seems, or that it is all a result of free will, and so on. Piper avoids mentioning the best solution so far put forward to the problem of evil. It is Leibniz’s theory that God does not create a better world because there isn’t one — that is, that (contrary to appearances) if one part of the world were improved, the ramifications would result in it being worse elsewhere, and worse overall. It is a “bump in the carpet” theory: push evil down here, and it pops up over there. Leibniz put it by saying this is the “Best of All Possible Worlds”. That phrase was a public relations disaster for his theory, suggesting as it does that everything is perfectly fine as it is. He does not mean that, but only that designing worlds is a lot harder than it looks, and determining the amount of evil in the best one is no easy matter. Though humour is hardly appropriate to the subject matter, the point of Leibniz’s idea is contained in the old joke, “An optimist is someone who thinks this is the best of all possible worlds, and a pessimist thinks..

This study forms a part of a larger investigation of the influence of the philosophy of Heraclitus of Ephesus on modern poetry. T. S. Eliot, to mention the best known of the many poets inspired by Heraclitus, selected two Heraclitus fragments (B 2 and B 60) as epigraphs for his “Burnt Norton”, the first of his Four Quartets. Eliot explained that he was drawn to the fragments because of their ‘ambiguity’ and ‘extraordinary poetic suggestiveness’. Similarly, in ‘This Solitude of Cataracts’, (...) Wallace Stevens spoke of ‘the flecked river which kept flowing and never the same way twice’ and elsewhere noted the ‘inherently poetic quality’ of many Heraclitean sayings. To gain some sense of the nature and magnitude of Heraclitus’ legacy for modern poetry we must first explore his vision of ‘a fiery cosmos being kindled in measures and extinguished in measures’ and a river into which one cannot step twice. -/- .

Complete information dispositional metasemantics says that our expressions get their meaning in virtue of what our dispositions to apply those terms would be given complete information. The view has recently been advanced and argued to have a number of attractive features. I argue that that it threatens to make the meanings of our words indeterminate and doesn’t do what it was that made a dispositional view attractive in the first place.

I will argue that the Kane-Widerker objection to Frankfurt examples is much weaker than is generally recognized. The Kane-Widerker objection holds that proponents of Frankfurt examples beg the question against incompatibilist accounts of free and responsible action by constructing examples that tacitly assume a compatibilist account of moral responsibility; that is, they assume that one can have non-derivative responsibility for choices that were not undetermined prior to their occurrence. The notion of an event, E, being ‘undetermined prior to its occurrence’ (...) is ambiguous. It can mean either (1) with respect to each time t prior to E’s occurrence, it is not the case that at t E’s occurrence is determined to take place, or it can mean (2) with respect to the whole collection of times prior to E’s occurrence, E’s occurrence is not determined to take place. Kane’s argument shows that (under certain constraints) if a choice is to be undetermined (in the second sense) prior to its occurrence, then a prior-sign Frankfurt example cannot be successful. But he fails to show that prior-sign Frankfurt examples cannot be constructed in which the choice is undetermined (in the first sense) prior to its occurrence, and he would need to do so in order to sustain his charge that those using Frankfurt examples beg the question against traditional incompatibilist accounts of responsibility. Widerker’s argument avoids the above problem, but at the cost of only applying to a rather restricted set of Frankfurt examples. (shrink)

The recent trend toward privately owned and operated prisons calls attention to a variety of issues involving human rights. The growing number of corporatized correctional institutions is especially notable in the United States, but it is also a global phenomenon in many countries. The reasons cited for privatizing prisons are usually economic; the opportunity to outsource prison services enables local political leaders to save tax revenue, and local communities are promised a chance to create new jobs and bring in a (...) new industry. This article will address the history of prisons and the recent trend toward privatizing prisons and the perception of prisons as a for-profit enterprise. This new economic order brings with it a set of human rights concerns, including the relationship of for-profit prisons to increased numbers of incarcerated persons and increased sentences, racism and classism. The contractual relationship between political leaders and prison corporations will be addressed, noting that conditions of liability frequently mean that prison administrations lack motivation to safeguard the human rights of prisoners. The human rights issues often extend outside of the private prison itself, having a negative effect on the local community. (shrink)

P. T. Geach has argued that it is impossible to demonstrate that the doctrine of the Trinity is consistent. I try to show why -- on a common understanding of the notion of consistency -- his reasoning is flawed and why, on Geach’s own principles, one should expect that if the doctrine of the Trinity is true then it will be possible to prove that the doctrine is consistent, and it will be possible to do this in a way that (...) makes no appeal to the truth of any religious doctrine.

While feminist aestheticians have long interrogated gendered, raced, and classed hierarchies in the arts, feminist philosophers still don’t talk much about popular music. Even though Angela Davis and bell hooks have seriously engaged popular music, they are often situated on the margins of philosophy. It is my contention that feminist aesthetics has a lot to offer to the study of popular music, and the case of popular music points feminist aesthetics to some of its own limitations and unasked questions. This (...) essay addresses the paucity of work in feminist philosophy and popular music by applying insights from other areas of feminist aesthetics to questions of popular music, and thereby using feminist aesthetics – specifically, Julia Kristea’s notion of female genius and the genius spectator – to critique itself.

Learning to see the continuity between our everyday decision-making and our decision-making around new biotechnologies is key to acclimatizing to our enhanced future. By excavating this decision-making, Singh helps us see that Ritalin isn’t really that big a deal and helps dispel what Malcolm Gladwell (1999) noted as the “strange inversion of moral responsibility” encouraged by books like ‘Ritalin Nation’ and ‘Running on Ritalin,’ whose authors “seek to make those parents and physicians trying to help children with A.D.H.D. feel guilty (...) for doing so.”.

This chapter challenges the common claim that vicious forms of argumentative practice, like interpersonal arrogance and discursive polarisation, are caused by martial metaphors, such as ARGUMENT AS WAR. I argue that the problem isn’t the metaphor, but our wider practices of metaphorising and the ways they are deformed by invidious cultural biases and prejudices. Drawing on feminist argumentation theory, I argue that misogynistic cultures distort practices of metaphorising in two ways. First, they spotlight some associations between the martial and argumentative (...) domains while occluding others, resulting in a sort of myopia. Second, those cultures interfere with a phenomenon I label normative isomorphism – the capacity of some structural metaphors to enable (and often encourage) a transfer of normative chracater traits from the source domain to the target domain. Crucially, the normative status of character trait often changes across domains—traits that are virtuous in the martial domain are often vicious in the argumentative domain, and vice versa. Sexist myopia tends to deform practices of metaphorising by interfering with normative isomorphism by privileging the transfer across domains of traits that recapitulate invidious cultural constructions of masculinity in terms of aggression, domination, and violence. Basically, the problem isn’t the metaphors, but the cultures. (shrink)
