In recent years, researchers in the “psychedelic renaissance” have been reinvestigating the therapeutic potential of psychedelic compounds for conditions like post-traumatic stress disorder, clinical anxiety/depression, and addiction. Each of these has treatment-resistant cases, sometimes decades in the making, but studies employing psychedelics to address them are yielding impressive results. Given the evolving legal situation around these substances as well as corporate investment in them, their availability and appeal promise to increase. The question facing Christians is: How do these developments impact (...) the theological significance of psychedelics as a broader phenomenon? This paper argues that since the population standing to benefit from these treatments is likely to include Christians, a thoughtful and rigorous response is necessary. The inquiry proceeds by analyzing some of the pertinent research, showing the insufficiency of previous Christian responses, and considering some hurdles and objections before issuing a call to theologize on this timely and important cultural moment.

Supporting Hamilton’s inclusive fitness theory, archival analyses of inheritance patterns in wills have revealed that people invest more of their estates in kin of closer genetic relatedness. Recent classroom experiments have shown that this genetic relatedness effect is stronger for relatives of direct lineage (children, grandchildren) than for relatives of collateral lineage (siblings, nieces, nephews). In the present research, multilevel modeling of more than 1,000 British Columbian wills revealed a positive effect of genetic relatedness on proportions of estates allocated to (...) relatives. This effect was qualified by an interaction with lineage, such that it was stronger for direct than for collateral relatives. Exploratory analyses of the moderating role of benefactors’ sex and estate values showed the genetic relatedness effect was stronger among female and wealthier benefactors. The importance of these moderators to understanding kin investment in modern humans is discussed. (shrink)

Philosophers often find themselves in disagreement with contemporary philosophers they know full well to be their epistemic superiors on the topics relevant to the disagreement. This looks epistemically irresponsible. I offer a detailed investigation of this problem of the reflective epistemic renegade. I argue that although in some cases the renegade is not epistemically blameworthy, and the renegade situation is significantly less common than most would think, in a troublesome number of cases in which the situation arises the renegade is (...) blameworthy in her disagreement with recognized epistemic superiors. I also offer some thoughts on what it would mean for philosophical practice for us to refrain from being renegades. Finally, I show how a new kind of radical skepticism emerges from modest theses regarding the renegade. (shrink)

Regardless of who you are or how you live your life, you disagree with millions of people on an enormous number of topics from politics, religion and morality to sport, culture and art. Unless you are delusional, you are aware that a great many of the people who disagree with you are just as smart and thoughtful as you are - in fact, you know that often they are smarter and more informed. But believing someone to be cleverer or more (...) knowledgeable about a particular topic usually won’t change your mind. Should it? This book is devoted to exploring this quandary - what should we do when we encounter disagreement, particularly when we believe someone is more of an authority on a subject than we are? The question is of enormous importance, both in the public arena and in our personal lives. Disagreement over marriages, beliefs, friendships and more causes immense personal strife. People with political power disagree about how to spend enormous amounts of money, about what laws to pass, or about wars to fight. If only we were better able to resolve our disagreements, we would probably save millions of lives and prevent millions of others from living in poverty. The first full-length text-book on this philosophical topic, Disagreement provides students with the tools they need to understand the burgeoning academic literature and its perspectives. Including case studies, sample questions and chapter summaries, this engaging and accessible book is the perfect starting point for students and anyone interested in thinking about the possibilities and problems of this fundamental philosophical debate.

This is a short essay that presents what I take to be the main questions regarding the epistemology of disagreement.

If you retain your belief upon learning that a large number and percentage of your recognized epistemic superiors disagree with you, then what happens to the epistemic status of your belief? I investigate that theoretical question as well has the applied case of philosophical disagreement—especially disagreement regarding purely philosophical error theories, theories that do not have much empirical support and that reject large swaths of our most commonsensical beliefs. I argue that even if all those error theories are false, either (...) (a) the average philosopher’s true commonsensical beliefs are epistemically impoverished, or (b) a good portion of philosophy is bunk and philosophers should give up most of their error theories despite the fact that their supporting arguments are generally as good as or even better than other philosophical arguments. (shrink)

This article argues, first, that there is plenty of agreement among philosophers on philosophically substantive claims, which fall into three categories: reasons for or against certain views, elementary truths regarding fundamental notions, and highly conditionalized claims. This agreement suggests that there is important philosophical progress. It then argues that although it's easy to list several potential kinds of philosophical progress, it is much harder to determine whether the potential is actual. Then the article attempts to articulate the truth that the (...) deniers of philosophical progress are latching on to. Finally, it comments on the significance of the agreement and progress.

In _The Sources of Normativity_, Christine M. Korsgaard argues that unconditional obligation can be accounted for in terms of practical identity. My argument in this paper is that practical identity cannot play this foundational role. More specifically, I interpret Korsgaard's argument as beginning with something analogous to Kant's fact of reason, viz. with the fact that our minds are reflective. I then try to show that her determination of this fact is inadequate and that this causes the argument concerning practical (...) identity to fail. Finally, I argue that a conception of the fact of reason more in line with what I take to be Kant's own is necessary to account for unconditional obligation. (shrink)

A new kind of skepticism about philosophy is articulated and argued for. The key premise is the claim that many of us are well aware that in the past we failed to have good responses to substantive objections to our philosophical beliefs. The conclusion is disjunctive: either we are irrational in sticking with our philosophical beliefs, or we commit some other epistemic sin in having those beliefs.

I’m going to argue for a set of restricted skeptical results: roughly put, we don’t know that fire engines are red, we don’t know that we sometimes have pains in our lower backs, we don’t know that John Rawls was kind, and we don’t even know that we believe any of those truths. However, people unfamiliar with philosophy and cognitive science do know all those things. The skeptical argument is traditional in form: here’s a skeptical hypothesis; you can’t epistemically neutralize (...) it, you have to be able to neutralize it to know P; so you don’t know P. But the skeptical hypotheses I plug into it are “real, live” scientific-philosophical hypotheses often thought to be actually true, unlike any of the outrageous traditional skeptical hypotheses (e.g., ‘You’re a brain in a vat’). So I call the resulting skepticism Live Skepticism. Notably, the Live Skeptic’s argument goes through even if we adopt the clever anti-skeptical fixes thought up in recent years such as reliabilism, relevant alternatives theory, contextualism, and the rejection of epistemic closure. Furthermore, the scope of Live Skepticism is bizarre: although we don’t know the simple facts noted above, many of us do know that there are black holes and other amazing facts. (shrink)

Those of us who take skepticism seriously typically have two relevant beliefs: (a) it’s plausible (even if false) that in order to know that I have hands I have to be able to epistemically neutralize, to some significant degree, some skeptical hypotheses, such as the brain-in-a-vat (BIV) one; and (b) it’s also plausible (even if false) that I can’t so neutralize those hypotheses. There is no reason for us to also think (c) that the BIV hypothesis, for instance, is plausible (...) or probably true. In order to take skepticism seriously it’s sufficient to hold (a) and (b); one need not hold (c). Indeed, philosophers who accept (a) and (b) never endorse (c). Show me a philosopher who suspects that he is a brain in a vat and I’ll show you someone who is deranged! That’s one thing that bothers undergraduates in philosophy. They object: why on earth do some philosophers take the BIV hypothesis to pose any threat at all to our beliefs given that those very same philosophers think that there’s no real chance that the BIV hypothesis is true? Sure, the BIV hypothesis is formally inconsistent with my belief that I have hands, so if the former is true then my belief is false. But so what? Why should that bare inconsistency matter so much? Is this strange attitude amongst philosophers the result of some logic fetish infecting the philosophical community? It is sometimes said that the skeptical hypotheses are not only inconsistent with our beliefs but are explanatory of our experiences, which is supposed to make them more of a threat. But students aren’t fooled: although the skeptical hypotheses may attempt to explain why our experience is as it is, it’s the kind of attempt appropriate for science fiction movies that are all special effects and virtually no plot. No one with any sense of reality will take the evil demon hypothesis to be even tenuously explanatory. (shrink)

Suppose you know that someone is your epistemic peer regarding some topic. You admit that you cannot think of any relevant epistemic advantage you have over her when it comes to that topic; you admit that she is just as likely as you to get P's truth-value right. Alternatively, you might know that she is your epistemic superior regarding the topic. And then after learning this about her you find out that she disagrees with you about P. In those situations (...) it appears that the confidence with which one holds one's belief should be significantly reduced. My primary goal in this essay is to present and reflect upon a set of cases of disagreement that have not been discussed in the literature but are vital to consider. I argue that in the new cases one is reasonable in not lowering one?s confidence in the belief. Then I articulate and defend an ambitious principle, the Disagreement Principle, meant to answer the question 'Under what conditions am I epistemically blameworthy in retaining my belief with the same level of confidence after I have discovered recognized peers or superiors who disagree with me?'.

Dignity, according to some recent arguments, is a useless concept, giving vague expression to moral intuitions that are better captured by other, better defined concepts. In this paper, I defend the concept of dignity against such skeptical arguments. I begin with a description of the defining features of the Kantian conception of dignity. I then examine one of the strongest arguments against that conception, advanced by Arthur Schopenhauer in On the Basis of Morality. After considering some standard accounts of dignity, (...) showing how they fail adequately to address Schopenhauer’s concern, I propose and defend a new account of dignity, drawing on the ontology of Jean-Luc Nancy.

For years philosophers argued for the existence of distinct yet materially coincident things by appealing to modal and temporal properties. For instance, the statue was made on Monday and could not survive being flattened; the lump of clay was made months before and can survive flattening. Such arguments have been thoroughly examined. Kit Fine has proposed a new set of arguments using the same template. I offer a critical evaluation of what I take to be his central lines of reasoning.

There is a long history of using facts about disagreement to argue that many of our most precious beliefs are false in a way that can make a difference in our lives. In this essay I go over a series of such arguments, arguing that the best arguments target beliefs that meet two conditions: (i) they have been investigated and debated for a very long time by a great many very smart people who are your epistemic superiors on the matter (...) and have worked very hard under optimal circumstances to figure out if the belief is true, and (ii) as far as you know these people have not come to any significant agreement on the belief and as far as you know those who agree with you are not, as a group, in a better position to judge the belief than those who disagree with you.

In this article I offer a three-pronged defense of Millian theories, all of which share the rough idea that all there is to a proper name is its referent, so it has no additional sense. I first give what I believe to be the first correct analysis of Kripke’s puzzle and its anti-Fregean lessons. The main lesson is that the Fregean’s arguments against Millianism and for the existence of semantically relevant senses (that is, individuative elements of propositions or belief contents (...) that are sensitive to our varying personal conceptions of the referents of those elements) are viciously circular. Thus, the Fregean must give new arguments for her central claims. Second, I offer an original, positive argument for the Millian idea that the thoughts that Cicero was bald and that Tully was bald are identical. Incredibly, the argument appeals to nothing but highly intuitive, pre-theoretical principles regarding folk psychological usage—traditionally the source of Fregean intuitions. Third, I examine one of the most important recent papers on Kripke’s puzzle, that by David Sosa (1996). Sosa claims to have found a way to turn the tables on Kripke’s puzzle by using it to argue against Millian theories. I argue that Sosa’s argument on behalf of the Fregean is question-begging. I conclude that Millian theories can be seriously defended without any use of theoretical constructs such as guises or Russellian propositions, and Fregeans need to start over arguing for their theory’s central claims.

"Under Magee's sensitive guidance a remarkably coherent interpretation of this period emerges."--Marshall Cohen, Listener. "The whole book has a marvellous air of casualness and clarity that makes it a delight to read."--Colin Wilson. Contemporary British philosophy is experiencing unprecedented openness to influences from abroad. New growth is evident in many areas of traditional philosophy which had been neglected by the logical positivists and the linguistic analysts. This sense of freedom permeates Magee's volume of conversations with leading British philosophers. Under Magee's (...) direction, the philosophers discuss other influential thinkers, such as Wittgenstein, Russell, Moore, and Austin, as well as ideas of universal interest, such as morality, art, religion, and social theory. As an introduction to contemporary British philosophy, a unique collection of candid commentaries by important thinkers, and study of fresh ideas, Modern British Philosophy is consistently lively and authoritative.

Fifteen dialogues drawn from the highly acclaimed BBC series review the tenets and theories of moral philosophy, poliitcal philosophy, the philosophy of language, and the philosophy of science.

In the early modern period, contempt emerged as a persistent theme in moral philosophy. Most of the moral philosophers of the period shared two basic commitments in their thinking about contempt. First, they argued that we understand the value of others in the morally appropriate way when we understand them from the perspective of the morally relevant community. And second, they argued that we are naturally inclined to judge others as contemptible, and that we must therefore interrupt that natural movement (...) of sense-bestowal in order to value others in the morally appropriate way. In this paper I examine in detail the arguments of Nicolas Malebranche and Immanuel Kant concerning the wrongness of contempt, emphasizing the ways in which they depend on conceptions of community and of the interruption of moral sense-bestowal. After showing how each of these arguments fails to comprehend the nature and the wrongness of contempt, I argue that we can find the resources for a more adequate account in the work of Jean-Luc Nancy, and specifically in his reflections on ontology and on the meaning of community.

According to Immanuel Kant, moral experience is made possible by respect, an absolutely unique feeling in which the sensible and the intelligible are given immediately together. This paper argues that Kant's moral philosophy underemphasizes the role of this sensibility at the heart of moral experience and that a more rigorous conception of respect, grounded in Michel Serres's concepts of the parasite, the excluded/included third, and noise would yield a moral philosophy more consistent with Kant's own basic insights.

In this paper I examine the conception of evil and the prescriptions for its mitigation that Michel Serres has articulated in his recent works. My explication of Serres’s argument centers on the claim, advanced in many different texts, that practices of exclusion, motivated by what he calls “the terrifying concupiscence of belonging,” are the primary sources of evil in the world. After explicating Serres’s argument, I examine three important objections, concluding that Serres overestimates somewhat the role of exclusion in perpetuating (...) evil and that his prescriptions for mitigating evil are excessively optimistic. (shrink)

In this paper I argue that a phenomenological account of moral sense-bestowal can provide valuable insight into the possibility of moral dilemmas. I propose an account of moral sense-bestowal that is grounded in the phenomenology of expression that Maurice Merleau-Ponty developed throughout the course of his philosophical work, and most explicitly in the period immediately following the publication of Phenomenology of Perception. Based on this Merleau-Pontian account of moral sense-bestowal, I defend the view that there are genuine moral dilemmas, i.e., (...) that we can be faced with situations of conflicting oughts that we cannot resolve without moral remainder. (shrink)

I argue in this paper that Maurice Merleau-Ponty provides a compelling account of alterity in The Prose of the World. I begin by tracing this account of alterity back to its roots in Phenomenology of Perception. I then show how the dynamic of expression articulated in The Prose of the World overcomes the limitations of the account given in the earlier work. After addressing an objection to the effect that the account given in The Prose of the World fails for (...) the same reason as the one given in Phenomenology of Perception, I argue that the key to Merleau-Ponty’s more successful account of alterity is provided by the phenomenon of orientation. (shrink)

I argue in this paper that Immanuel Kant's account of the moral wrongness of contempt in the Metaphysics of Morals provides important resources for our understanding of the nature of moral subjectivity. Although Kant typically emphasizes the subject's position as autonomous addressor of the moral law, his remarks on contempt bring into relief a dynamic relationship at the heart of practical subjectivity between the addressor and addressee positions. After tracing the development of reflection concerning the addressor and addressee positions in (...) early modern philosophy, beginning with Francisco Suarez and Samuel Pufendorf, I articulate and defend what I take to be a Kantian conception of the relation between those positions. More specifically, I argue that to be a moral subject at all is necessarily to position oneself as the addressor of the moral law, but that one must at the same time maintain oneself in the addressee position, resisting the full conversion to the addressor position that autonomy seems to demand.

We all can identify many contemporary philosophy professors we know to be theists of some type or other. We also know that often enough their nontheistic beliefs are as epistemically upstanding as the non-theistic beliefs of philosophy professors who aren’t theists. In fact, the epistemic-andnon-theistic lives of philosophers who are theists are just as epistemically upstanding as the epistemic-and-non-theistic lives of philosophers who aren’t theists. Given these and other, similar, facts, there is good reason to think that the pro-theistic beliefs (...) of theistic philosophers are frequently epistemically upstanding. Given their impeccable epistemic credentials on non-theistic matters, the amount of careful thought that lies behind their theism, the large size of the community of philosophical theists, as well as other, similar facts, it would be surprising if all or even most of their pro-theistic beliefs were epistemically blameworthy in some or other signicant sense tied to charges such as ‘He should know better than to believe that’ (so mere false belief need not be blameworthy in this sense; the use of ‘blameworthy’ will be claried below). Of course some of the pro-theistic beliefs of some theistic philosophers are epistemically blameworthy; the mere large numbers of fallible theistic philosophers almost guarantees it. My point here is that it would be unexpected if most of the pro-theistic beliefs of theistic philosophers were epistemically blameworthy. (shrink)

Content externalism is the dominant view in the philosophy of mind. Content essentialism, the thesis that thought tokens have their contents essentially, is also popular. And many externalists are supporters of such essentialism. However, endorsing the conjunction of those views either (i) commits one to a counterintuitive view of the underlying physical nature of thought tokens or (ii) commits one to a slightly different but still counterintuitive view of the relation of thought tokens to physical tokens as well as a (...) rejection of realist physicalism. In this essay I reveal the problem and articulate and adjudicate among the possible solutions. I will end up rejecting content essentialism. (shrink)

I argue in this paper that some of the most basic commitments of Kantian ethics can be understood as grounded in the dynamic of sense that Merleau-Ponty describes in his Phenomenology of Perception. Specifically, I argue that Merleau-Ponty’s account supports the importance of universalizability as a test for the moral permissibility of particular acts as well as the idea that the binding character of the moral law is given as something like a fact of reason. But I also argue that (...) Merleau-Ponty’s account of reversibility suggests an important dimension of moral experience that is given in the experience of contact and that is underthematized in moral philosophies like Kant’s that emphasize the role of universalizability. Finally, I advance a positive account of moral experience that is centered on the idea of tact as ambiguous imperative. (shrink)

One of the dominant themes structuring the trajectory of Jean-François Lyotard's philosophical work is his concern to think the event in a way that renders it intelligible, but that also respects the alterity and the uncanniness that are essential to it. In this paper I defend Lyotard's earlier understanding of the event, articulated most thoroughly in Discours, figure, from the criticisms of the later Lyotard, articulated most thoroughly in The Differend. More specifically, I attempt to demonstrate that the event, as (...) disruption of the stable system of signification, is given immediately with the signification that it disrupts. (shrink)

In The Troubadour of Knowledge, Michel Serres demonstrates, by means of an extended discussion of learning, that our capacity to adopt a position presupposes a kind of disorienting exposure to a dimension of pure possibility that both subtends and destabilizes that position. In this paper I trace out the implications of this insight for our understanding of obligation, especially as it is articulated in the moral philosophy of Immanuel Kant. Specifically, I argue that obligation is given along with a dimension (...) of moral possibility, and not, as Kant thought, as an unmediated fact of reason. (shrink)

According to Immanuel Kant, the objective validity of obligation is given as a fact of reason, which forces itself upon us and which requires no deduction of the kind that he had provided for the categories in the Critique of Pure Reason. This fact grounds a moral philosophy that treats obligation as a good that trumps all others and that presents the moral subject as radically responsible, singled out by an imperatival address. Based on conceptions of indifference and facticity that (...) Charles Scott has articulated in his recent work, I argue that these broadly Kantian commitments are mistaken. More specifically, I argue that the fact of obligation is given along with a dimension of indifference that disrupts the hierarchical relation between moral and non-moral goods and that renders questionable the unconditional character of responsibility. (shrink)

Philosophical expertise consists in knowledge, but it is controversial what this knowledge consists in. I focus on three issues: the extent and nature of knowledge of philosophical truths, how this philosophical knowledge is related to philosophical progress, and skeptical challenges to philosophical knowledge.

One of Moore’s paradoxical sentence types is ‘P, but I believe ~P’. Mooreans have assumed that all tokens of that sentence type are absurd in some way: epistemically, pragmatically, semantically, or assertively. And then they proceed to debate what the absurdity really is. I argue that if one has the appropriate philosophical views, then one can rationally assert tokens of that sentence type, and one can be epistemically reasonable in the corresponding compound belief as well.

In this essay I try to motivate and formulate the main epistemological questions to ask about the phenomenon of religious disagreement. I will not spend much time going over proposed answers to those questions. I address the relevance of the recent literature on the epistemology of disagreement. I start with some fiction and then, hopefully, proceed with something that has at least a passing acquaintance with truth.

By considering the epistemology and relations among certain philosophical problems, I argue for a disjunctive thesis: either (1) it is highly probable that there are (i) several (ii) mutually independent philosophical reductios of highly commonsensical propositions that are successful—so several aspects of philosophy have succeeded at refuting common sense—or (2) there is enough hidden semantic structure in even simple sentences of natural language to make philosophers highly unreliable at spotting deductive validity in some of the simplest cases—so we are much (...) worse at logic than we think and cannot, in general, know when our own arguments are valid. The untoward consequences of each disjunct are explained. (shrink)

Call the conventionalist challenge to natural rights theory the claim that natural rights theory fails to capture the fact that moral rights are shaped by social and legal convention. While the conventionalist challenge is a natural concern, it is less than clear what this challenge amounts to. This paper aims to develop a clear formulation strong enough to put pressure on the natural rights theorist and precise enough to clarify what an adequate response would require.

The Burge-Putnam thought experiments have generated the thesis that beliefs are not fixed by the constitution of the body. However, many philosophers have thought that if this is true then there must be another content-like property. Even if the contents of our attitudes such as the one in ‘believes that aluminum is a light metal’, do not supervene on our physical makeups, nevertheless people who are physical duplicates must be the same when it comes to evaluating their rationality and explaining (...) their actions. I argue that the considerations motivating this view are best handled with just the ordinary ‘that’-clause contents. (shrink)

Many philosophers have used premises about concepts and rationality to argue that the protagonists in the various Twin Earth thought experiments do not have the concepts that content externalists say they have. This essay argues that this popular internalist argument is flawed in many different ways, and more importantly it cannot be repaired in order to cast doubt on externalism.

We present a geometric construction that yields completeness results for modal logics including K4, KD4, GL and GL n with respect to certain subspaces of the rational numbers. These completeness results are extended to the bimodal case with the universal modality.
