Intuitively, a question is indeterminate just in case it is unsettled, not merely epistemically, but metaphysically. We ordinarily ascribe indeterminacy by saying that there is no fact of the matter. We say for instance that there is no fact of the matter how many clouds exist. The distribution of water droplets in the sky would appear to settle that there are some clouds, but not how many. ;On the one hand, it seems obvious that certain questions are indeterminate. On the (...) other hand, it seems easy to reduce an arbitrary ascription of indeterminacy to absurdity: Suppose that it is indeterminate---that is, metaphysically unsettled---whether Jud is bald. Because it is true that Jud is bald only if it is metaphysically settled that he is bald, and because it is true that Jud is not bald only if it is metaphysically settled that he is not bald, it is not true that Jud is bald and not true that Jud is not bald. Because Jud is bald only if it is true that he is bald, and because Jud is not bald only if it is true that he is not bald, Jud is not bald and Jud is not not bald. This is a contradiction. Hence, our supposition is false. Moreover, because the issue of whether Jud is bald was chosen arbitrarily, the argument generalizes: indeterminacy is impossible. ;We are faced with a dilemma: take the anti-indeterminacy argument at face value and look for a way to explain away our pro-indeterminacy intuitions, or take our intuitions at face value and look for a way to reject the argument. Many philosophers are inclined toward the latter route, but I want to take the first step toward justifying the former. ;After emphasizing the costs of rejecting the preceding sort of argument, I show how five of the most salient phenomena that give rise to pro-indeterminacy intuitions can be accounted for without postulating genuine indeterminacy. I examine explicitly incomplete definitions, hidden relativity, vagueness, comparatives, and subjunctive conditionals. In each case I suggest a way to account for the phenomenon without postulating indeterminacy. (shrink)

On an optimistic version of realist moral epistemology, a significant range of ordinary moral beliefs, construed in realist terms, constitute knowledge—or at least some weaker positive epistemic status, such as epistemic justification. The “debunking challenge” to this view grants prima facie justification but claims that it is “debunked” (i.e., defeated), yielding the final verdict that moral beliefs are ultima facie unjustified. Notable candidate “debunkers” (i.e., defeaters) include the so-called “evolutionary debunking arguments,” the “Benacerraf-Field Challenge,” and persistent moral disagreement among epistemic (...) peers. Such defeaters are best treated as higher-order evidence—viz., evidence contesting the merits of the first-order evidence on which moral beliefs are based. This chapter first develops a theory of higher-order defeat in general, which it then applies to debunking in particular. The result: the challenge fails entirely on epistemic grounds—regardless of whether or not its empirical and metaphysical presuppositions are correct. An advantage of this purely epistemic defense over alternative strategies is that the former extends even to laypersons who themselves lack the expertise necessary to formulate an adequate response. However, this leaves open the prospects for non-epistemological interpretations of debunking (e.g., moral or ontological). The chapter therefore concludes with brief suggestions in that direction.

This chapter defines "epistemology," introduces the key epistemological questions, and briefly outlines how the field has evolved over time. It serves as the introduction to the edited collection, Introduction to Philosophy: Epistemology (a volume in the Introduction to Philosophy open textbook series edited by Christina Hendricks).

A common view among nontheists combines the de jure objection that theism is epistemically unacceptable with agnosticism about the de facto objection that theism is false. Following Plantinga, we can call this a “proper” de jure objection—a de jure objection that does not depend on any de facto objection. In his Warranted Christian Belief, Plantinga has produced a general argument against all proper de jure objections. Here I first show that this argument is logically fallacious (it makes subtle probabilistic fallacies (...) disguised by scope ambiguities), and proceed to lay the groundwork for the construction of actual proper de jure objections.

An action is unratifiable when, on the assumption that one performs it, another option has higher expected utility. Unratifiable actions are often claimed to be somehow rationally defective. But in some cases where multiple options are unratifiable, one unratifiable option can still seem preferable to another. We should respond, I argue, by invoking a graded notion of ratifiability.

According to the traditional analysis of propositional knowledge (which derives from Plato's account in the Meno and Theaetetus), knowledge is justified true belief. This chapter develops the traditional analysis, introduces the famous Gettier and lottery problems, and provides an overview of prospective solutions. In closing, I briefly comment on the value of conceptual analysis, note how it has shaped the field, and assess the state of post-Gettier epistemology.

The question of whether all living things are really just complex physical ones, or whether instead there are biological entities or characteristics that cannot be fully characterized in physical terms, has historical roots buried centuries deep. Carl Hempel considers this question as an empirical one for modern science to address. Hempel’s concern is not with the answer to the question, but rather with the methods by which it may be evaluated. He considers the position of those he calls “mechanists,” that (...) all living things and their biological characteristics are nothing more than complex physical systems, as equivalent to the view that in some significant sense all accurate biological theories are implied by physical ones. In so doing, Hempel seeks to draw conclusions regarding the unity of science more broadly. This paper argues that Hempel’s account, though perhaps succeeding in a crucial first step, fails on numerous points afterwards. Using the morals that may be draw from these failures, I suggest rough outlines of some alternative accounts of intertheoretic reduction. (shrink)

When it comes to contentious conversations, the call for civility is commonplace. Rarely do we hear a call for nonviolence in communication. This is unfortunate, since nonviolence is a better standard than civility (a standard I critiqued in part one of this three-part series). Part of the problem is that a framework for communicative nonviolence has not (to my knowledge) been fully developed. Mohandas (“Mahatma”) Gandhi, the “father of nonviolence,” is widely known for nonviolence, but primarily in the realm of (...) noncommunicative action. However, there is a natural line of development in that direction from elements in his thought: Gandhi derives his commitment to nonviolence ("ahimsa" in Sanskrit) from his "law of Truth," which directs us to follow “Truth in thought, Truth in speech, and Truth in action." Inspired by Gandhi among others, Marshall B. Rosenberg developed what he termed "Nonviolent Communication" (NVC). Valuable though NVC is, it is most applicable to particular conversational contexts. It is but one part of a broader nonviolent framework, which I’ll call "ahimsic communication" (AC) to distinguish it from NVC. In this second installment of the series, I develop a framework for AC.

Introduction to Philosophy: Epistemology engages first-time philosophy readers on a guided tour through the core concepts, questions, methods, arguments, and theories of epistemology—the branch of philosophy devoted to the study of knowledge. After a brief overview of the field, the book progresses systematically while placing central ideas and thinkers in historical and contemporary context. The chapters cover the analysis of knowledge, the nature of epistemic justification, rationalism vs. empiricism, skepticism, the value of knowledge, the ethics of belief, Bayesian epistemology, social (...) epistemology, and feminist epistemologies. Along the way, instructors and students will encounter a wealth of additional resources and tools: chapter learning outcomes, key terms, images of philosophers and related art, useful diagrams and tables, boxes containing excerpts and other supplementary material, questions for reflection, suggestions for further reading, and a glossary. For an undergraduate survey epistemology course, Introduction to Philosophy: Epistemology is ideal when used as a main text paired with primary sources and scholarly articles. For an introductory philosophy course, select book chapters are best used in combination with chapters from other books in the Introduction to Philosophy open textbook series (edited by Christina Hendricks).

In parts one and two of this three-part series, I developed a framework for ahimsic (nonviolent) communication (AC) as an alternative to the standard communicative norm of civility. The framework presented for AC offers various categories of resistance to violence, including nonviolent forms of negotiation, compromise, protest, verbal force, verbal distraction, argumentation, and communicative satyagraha (Gandhian nonviolence applied to communication). I also provided a range of real-life examples of successful AC resistance, including the stories of Derek Black, Daryl Davis, James (...) Lawson, and Antoinette Tuff. These examples demonstrate that AC “works” even against neo-Nazis, KKK grand wizards, angry punch-throwing bikers, and active school shooters. In this third and final installment, I will explain why AC works—better than any form of violent communication (VC). My main claim is that AC derives strategic power from its moral power. As various components of my argument are drawn from the nonviolence tradition more generally, what follows will double as a primer on the morality of nonviolence. However, we will also see significant differences in how we must adapt nonviolent strategy and morality to the case of communication. (shrink)

A concise open-access textbook intended for an undergraduate audience, which brings together essential selections from Gandhi on nonviolence with supplementary materials, including: a preface; boxes providing examples, historical notes, extended explanations, and related philosophical work; overviews of post-Gandhian developments in nonviolence; diagrams, tables, and photos; discussion questions; reading and viewing suggestions; and a glossary.

The two standard theories of vagueness—vagueness-as-ignorance and vagueness-asindeterminacy—agree on the following principle: if you are certain that it is clearly vague whether p, then you clearly should not believe p and you clearly should not believe not-p. I argue against the principle, and thus against the two standard theories. I offer an explanation of the initial appeal of the principle. And I show how a rival principle helps to better explain a recalcitrant trio of widely accepted data.

Higher-order evidence is, roughly, evidence of evidence. The idea is that evidence comes in levels. At the first, or lowest, evidential level is evidence of the familiar type—evidence concerning some proposition that is not itself about evidence. At a higher evidential level the evidence concerns some proposition about the evidence at a lower level. Only in relatively recent years has this less familiar type of evidence been explicitly identified as a subject of epistemological focus, and the work on it remains (...) relegated to a small circle of authors and a short stack of published articles—far disproportionate to the attention it deserves. It deserves to occupy center stage for several reasons. First, higher-order evidence frequently arises in a strikingly diverse range of epistemic contexts, including testimony, disagreement, empirical observation, introspection, and memory, among others. Second, in many of the contexts in which it arises, such evidence plays a crucial epistemic role. Third, the precise role it plays is complex, gives rise to a number of interesting epistemological puzzles, and for these reasons remains controversial and is not yet fully understood. As such, higher-order evidence merits systematic investigation. This thesis undertakes such an investigation. It aims to produce a thorough account of higher-order evidence—what it is, how it works, and its epistemic consequences. Chapter 1 serves as a general introduction to the topic and an overview of the existing literature, but primarily aims to further elucidate the concept of higher-order evidence and build a theoretical framework for later chapters. Chapter 2 develops an account of what I call “higher-order support”: the bearing higher-order evidence has, not on corresponding “lower-order evidence” (roughly, the evidence the higher-order evidence is about), but on corresponding “object-level propositions” (roughly, the propositions the higher-order evidence alleges the lower-order evidence to be about). Chapter 3 develops an account of “levels interaction”: the effect on overall support when the different evidential levels combine. Chapter 4 identifies important consequences of the theoretical results of the previous two chapters and applies the theory to four select cases of current epistemological controversy—testimony, memory, the closure of inquiry, and disagreement.

Despite there being deep lines of convergence between the philosophies of Alfred North Whitehead, C. S. Peirce, William James, John Dewey, and other classical American philosophers, it remains an open question whether Whitehead is a pragmatist, and conversation between pragmatists and Whitehead scholars have been limited. Indeed, it is difficult to find an anthology of classical American philosophy that includes Whitehead’s writings. These camps began separately, and so they remain. This volume questions the wisdom of that separation, exploring their connections, (...) both historical and in application. The essays in this volume embody original and creative work by leading scholars that not only furthers the understanding of American philosophy, but seeks to advance it by working at the intersection of experience and reality to incite novel and creative thought. This exploration is long overdue. Specific questions that are addressed are: Is Whitehead a pragmatist? What contrasts and affinities exist between American pragmatism and Whitehead’s thought? What new questions, strategies, and critiques emerge by juxtaposing their distinct perspectives? -/- . (shrink)

In "The Philosophy of Nature," Brian Ellis provides a clear and forthright general summation of, and introduction to, the new essentialist position. Although the theory that the laws of nature are immanent in things, rather than imposed on them from without, is an ancient one, much recent work has been done to revive interest in essentialism and "The Philosophy of Nature" is a distinctive contribution to this lively current debate. Brian Ellis exposes the philosophical and scientific credentials of (...) the prevailing Humean metaphysic as less than compelling and makes the case for new essentialism as an alternative metaphysical perspective in lucid and unambiguous terms. This book develops this alternative metaphysic and considers the consequences for philosophy, and for some other areas of investigation, of working with such a metaphysic. Ellis argues that these consequences are profound and that a new essentialism provides a comprehensive new philosophy of nature for a modern scientific understanding of the world. (shrink)

I argue that, unlike your brain, you are not composed of other things: you are simple. My argument centers on what I take to be an uncontroversial datum: for any pair of conscious beings, it is impossible for the pair itself to be conscious. Consider, for instance, the pair comprising you and me. You might pinch your arm and feel a pain. I might simultaneously pinch my arm and feel a qualitatively identical pain. But the pair we form would not (...) feel a thing.1 Pairs of people themselves are incapable of experience. Call this The Datum. What explains The Datum? I think the following exhaust the reasonable options. (1) Pairs of people lack a sufficient number of immediate parts. (2) Pairs of people lack immediate parts capable of standing in the right sorts of relations to each other and their environment. (3) Pairs of people lack immediate parts of the right nature. (4) Pairs of people are not structures (they are unstructured collections of their two immediate parts). (5) Some combination of (1) – (4). Finally, (6) pairs of people are not simple. (shrink)

The “scientific essentialist” doctrine asserts that the following are examples of a posteriori necessary identities: water is H2O; gold is the element with atomic number 79; and heat is the motion of molecules. Evidence in support of this assertion, however, is difficult to find. Both Hilary Putnam and Saul Kripke have argued convincingly for the existence of a posteriori necessities. Furthermore, Kripke has argued for the existence of a posteriori necessary identities in regard to a particular class of statements involving (...) proper names. Neither Kripke nor Putnam, however, has argued convincingly that sentences containing syntactically complex terms or descriptive phrases can express a posteriori necessary identities. I will argue by way of a hypothetical example that ‘water is H2O’ does not express a necessary identity. My argument is unique in that it attacks the relevant sufficiency claim needed to underwrite this putative necessary identity.1 That is, even if we grant that water is necessarily composed of H2O, we should not accept that H2O necessarily forms water.

This edition of G. E. Moore's notes taken at Wittgenstein's seminal Cambridge lectures in the early 1930s provides, for the first time, an almost verbatim record of those classes. The presentation of the notes is both accessible and faithful to their original manuscripts, and a comprehensive introduction and synoptic table of contents provide the reader with essential contextual information and summaries of the topics in each lecture. The lectures form an excellent introduction to Wittgenstein's middle-period thought, covering a broad range (...) of philosophical topics, ranging from core questions in the philosophy of language, mind, logic, and mathematics, to illuminating discussions of subjects on which Wittgenstein says very little elsewhere, including ethics, religion, aesthetics, psychoanalysis, and anthropology. The volume also includes a 1932 essay by Moore critiquing Wittgenstein's conception of grammar, together with Wittgenstein's response. A companion website offers access to images of the entire set of source manuscripts. (shrink)

Stephen Schiffer claims (in the present collection) that vagueness is essentially a psychological phenomenon. According to him, vagueness should not be explicated in terms of absent truth values or incurable ignorance—that is, as a semantic or an epistemic phenomenon—but rather in terms of a peculiar new type of propositional attitude. Schiffer introduces the notion of a vagueness-related partial belief and bases upon it both a novel analysis of the notion of a borderline case and a novel solution to the sorites (...) paradox. He defines standard partial beliefs (SPBs) as partial beliefs which can under suitable idealization be identified with subjective probability (p. 221). He defines vagueness-related partial beliefs (VPBs) as partial beliefs which cannot be so identified (p. 223). He adds that VPBs, by contrast to SPBs, do not measure uncertainty or generate corresponding likelihood beliefs (p. 223). He defines a paradigm VPB (VPB*) as a VPB held by an ideally rational thinker who knows, with certainty, that she is in ideal epistemic conditions with respect to the content of her VPB (p. 227). Schiffer then analyzes the notion of a borderline case as follows: x is to some extent a borderline case of being F just in case someone could have a VPB* that x is F. Near the end of his paper, Schiffer suggests the possibility of reformulating his analysis in.. (shrink)

On two standard views of vagueness, vagueness as to whether Harry is bald entails that nobody knows whether Harry is bald—either because vagueness is a type of missing truth, and so there is nothing to know, or because vagueness is a type of ignorance, and so even though there is a truth of the matter, nobody can know what that truth is. Vagueness as to whether Harry is bald does entail that nobody clearly knows that Harry is bald and that (...) nobody clearly knows that Harry is not bald. But it does not entail that nobody knows that Harry is bald or that nobody knows that Harry is not bald. Hence, the two standard views of vagueness are mistaken. (shrink)

When making substituted judgments for incapacitated patients, surrogates often struggle to guess what the patient would want if they had capacity. Surrogates may also agonize over having the (sole) responsibility of making such a determination. To address such concerns, a Patient Preference Predictor (PPP) has been proposed that would use an algorithm to infer the treatment preferences of individual patients from population-level data about the known preferences of people with similar demographic characteristics. However, critics have suggested that even if such (...) a PPP were more accurate, on average, than human surrogates in identifying patient preferences, the proposed algorithm would nevertheless fail to respect the patient’s (former) autonomy since it draws on the ‘wrong’ kind of data: namely, data that are not specific to the individual patient and which therefore may not reflect their actual values, or their reasons for having the preferences they do. Taking such criticisms on board, we here propose a new approach: the Personalized Patient Preference Predictor (P4). The P4 is based on recent advances in machine learning, which allow technologies including large language models to be more cheaply and efficiently ‘fine-tuned’ on person-specific data. The P4, unlike the PPP, would be able to infer an individual patient’s preferences from material (e.g., prior treatment decisions) that is in fact specific to them. Thus, we argue, in addition to being potentially more accurate at the individual level than the previously proposed PPP, the predictions of a P4 would also more directly reflect each patient’s own reasons and values. In this article, we review recent discoveries in artificial intelligence research that suggest a P4 is technically feasible, and argue that, if it is developed and appropriately deployed, it should assuage some of the main autonomy-based concerns of critics of the original PPP. We then consider various objections to our proposal and offer some tentative replies. (shrink)

As sociologists deepen their examinations of human rights in their teaching, research, and thinking, it is essential that such work is conducted in a manner that is both mindful and critical of the knowledge we are building upon in sociology and human rights. As the authors of this volume reveal, creating sociological knowledge that examines human rights for the expansion of human rights is something that sociologists are well equipped to undertake, whether through the use of mathematics, comparative-historical analysis, the (...) study of emotions, conversations, or social psychology. In these chapters you will find the roots of the study of human rights deep within sociological research and thinking as well as emerging techniques that will push the discipline as it seeks to expand understanding of human rights together with so many other aspects of the social condition.

Graeme Forbes (2011) raises some problems for two-dimensional semantic theories. The problems concern nested environments: linguistic environments where sentences are nested under both modal and epistemic operators. Closely related problems involving nested environments have been raised by Scott Soames (2005) and Josh Dever (2007). Soames goes so far as to say that nested environments pose the “chief technical problem” for strong two-dimensionalism. We call the problem of handling nested environments within two-dimensional semantics “the nesting problem”. We show that the two-dimensional (...) semantics for attitude ascriptions developed in Chalmers (2011a) has no trouble accommodating certain forms of the nesting problem that involve factive verbs such as “know” or “establish”. A certain form of the nesting problem involving apriority and necessity operators does raise an interesting puzzle, but we show how a generalized version of the nesting problem arises independently of two-dimensional semantics—it arises, in fact, for anyone who accepts the contingent a priori. We, then, provide a two-dimensional treatment of the apriority operator that fits the two-dimensional treatment of attitude verbs and apply it to the generalized nesting problem. We conclude that two-dimensionalism is not seriously threatened by cases involving the nesting of epistemic and modal operators. (shrink)

David DeGrazia’s stated purposes for Taking Animals Seriously are to apply a coherentist methodology to animal ethics, to do the philosophical work necessary for discussing animal minds, and to fill in some of the gaps in the existing literature on animal ethics.

In this first installment of a three-part series, I focus on the critique of civility. In so doing, I do not defend incivility. In fact, part of my critique of civility extends equally to incivility. My position is that we must move our normative discourse beyond both the thesis of civility and the antithesis of incivility to a synthesis that reframes the discussion in terms of nonviolence.

A natural view of testimony holds that a source's statements provide one with evidence about what the source believes, which in turn provides one with evidence about what is true. But some theorists have gone further and developed a broadly analogous view of memory. According to this view, which this essay calls the “diary model,” one's memory ordinarily serves as a means for one's present self to gain evidence about one's past judgments, and in turn about the truth. This essay (...) rejects the diary model's analogy between memory and testimony from one's former self, arguing first that memory and a diary differ with respect to their psychological roles, and second that this psychological difference underwrites important downstream epistemic differences. The resulting view stands opposed to prominent discussions of memory and testimony, which either, like the diary model, treat memory by analogy to what we naively wish to say about testimony, or which instead attempt to extend to testimony the epistemically preservative role of memory.

This paper critically examines currently influential transparency accounts of our knowledge of our own beliefs that say that self-ascriptions of belief typically are arrived at by “looking outward” onto the world. For example, one version of the transparency account says that one self-ascribes beliefs via an inference from a premise to the conclusion that one believes that premise. This rule of inference reliably yields accurate self-ascriptions because you cannot infer a conclusion from a premise without believing the premise, and so (...) you cannot infer from a premise that you believe the premise unless you do believe it. I argue that this procedure cannot be a source of justification, however, because one can be justified in inferring from p that q only if p amounts to strong evidence that q is true. This is incompatible with the transparency account because p often is not very strong evidence that you believe that p. For example, unless you are a weather expert, the fact that it will rain is not very strong evidence that you believe it will rain. After showing how this intuitive problem can be made precise, I conclude with a broader lesson about the nature of inferential justification: that beliefs, when justified, must be underwritten by beliefs, when justified, must be underwritten by evidential relationships between the facts or propositions which those beliefs represent.

Evidence suggests that psychedelics bring about their therapeutic outcomes in part through the subjective or qualitative effects they engender and how the individual interprets the resulting experiences. However, psychedelics are contraindicated for individuals who have been diagnosed with certain mental illnesses, on the grounds that these subjective effects may be disturbing or otherwise counter-therapeutic. Substantial resources are therefore currently being devoted to creating psychedelic substances that produce many of the same biological changes as psychedelics, but without their characteristic subjective effects. (...) In this article, we consider ethical issues arising from the prospect of such potential “nonsubjective” psychedelics. We are broadly supportive of efforts to produce such substances for both scientific and clinical reasons. However, we argue that such nonsubjective psychedelics should be reserved for those special cases in which the subjective effects of psychedelics are specifically contraindicated, whereas classic psychedelics that affect subjective experience should be considered the default and standard of care. After reviewing evidence regarding the subjective effects of psychedelics, we raise a number of ethical concerns around the prospect of withholding such typically positive, meaningful, and therapeutic experiences from most patients.
