Perfect for students with no background in logic or philosophy, Simple Formal Logic provides a full system of logic adequate to handle everyday and philosophical reasoning. By keeping out artificial techniques that aren’t natural to our everyday thinking process, Simple Formal Logic trains students to think through formal logical arguments for themselves, ingraining in them the habits of sound reasoning. Simple Formal Logic features: a companion website with abundant exercise worksheets, study supplements (including flashcards for symbolizations and for deduction rules), (...) and instructor’s manual two levels of exercises for beginning and more advanced students a glossary of terms, abbreviations and symbols. This book arose out of a popular course that the author has taught to all types of undergraduate students at Loyola University Chicago. He teaches formal logic without the artificial methods–methods that often seek to solve farfetched logical problems without any connection to everyday and philosophical argumentation. The result is a book that teaches easy and more intuitive ways of grappling with formal logic–and is intended as a rigorous yet easy-to-follow first course in logical thinking for philosophy majors and non-philosophy majors alike.

Human Knowledge, 3/e, offers an unparalleled introduction to our ancient struggle to understand our own intellectual experience. (shrink)

What exactly are we conscious beings? Do we have immaterial souls, souls that are substances and can survive the destruction of our physical bodies? Richard Swinburne has recently given an affirmative answer to the latter question on the basis of a strikingly simple Cartesian argument. This paper shows why Swinburne’s argument ultimately fails, owing to an instructive dilemma concerning the logical possibility of conscious beings’ surviving bodily destruction. Perhaps we do have substantial immaterial souls, but Swinburne’s Cartesian argument, we shall (...) see, does not cogently deliver the conclusion that we do. (shrink)

The main purpose of this paper is to define and study a particular variety of Montague-Scott neighborhood semantics for modal propositional logic. We call this variety the first-order neighborhood semantics because it consists of the neighborhood frames whose neighborhood operations are, in a certain sense, first-order definable. The paper consists of two parts. In Part I we begin by presenting a family of modal systems. We recall the Montague-Scott semantics and apply it to some of our systems that have hitherto (...) be uncharacterized. Then, we define the notion of a first-order indefinite semantics, along with the more specific notion of a first-order uniform semantics, the latter containing as special cases the possible world semantics of Kripke. In Part II we prove consistency and completeness for a broad range of the systems considered, with respect to the first-order indefinite semantics, and for a selected list of systems, with respect to the first-order uniform semantics. The completeness proofs are algebraic in character and make essential use of the finite model property. A by-product of our investigations is a result relating provability in S-systems and provability in T-systems, which generalizes a known theorem relating provability in the systems S 2° and C 2.

This article applies the Kantian doctrine of respect for persons to the problem of sweatshops. We argue that multinational enterprises are properly regarded as responsible for the practices of their subcontractors and suppliers. We then argue that multinationalenterprises have the following duties in their off-shore manufacturing facilities: to ensure that local labor laws are followed; to refrain from coercion; to meet minimum safety standards; and to provide a living wage for employees. Finally, we consider and reply to the objection that (...) improving health and safety conditions and providing a living wage will cause greater harm than good. (shrink)

I argue that a certain type of naturalist should not accept a prominent version of the no-miracles argument (NMA). First, scientists (usually) do not accept explanations whose explanans-statements neither generate novel predictions nor unify apparently disparate established claims. Second, scientific realism (as it appears in the NMA) is an explanans that makes no new predictions and fails to unify disparate established claims. Third, many proponents of the NMA explicitly adopt a naturalism that forbids philosophy of science from using any methods (...) not employed by science itself. Therefore, such naturalistic philosophers of science should not accept the version of scientific realism that appears in the NMA. (shrink)

I provide an account of the cognitive attitude of trust that explains the role trust plays in the planning of rational agents. Many authors have dismissed choosing to trust as either impossible or irrational; however, this fails to account for the role of trust in practical reasoning. A can have therapeutic, coping, or corrective reasons to trust B to ${\phi}$ , even in the absence of evidence that B will ${\phi}$ . One can choose to engage in therapeutic trust to (...) inspire trustworthiness, coping trust to simplify one’s planning, or corrective trust to avoid doing a testimonial injustice. To accommodate such types of trust, without accepting doxastic voluntarism, requires an account of the cognitive attitude of trust broader than belief alone. I argue that trust involves taking the proposition that someone will do something as a premise in one’s practical reasoning, which can be a matter of believing or accepting the proposition. I defend this account against objections that it (i) provides insufficient rational constraints on trust, (ii) conflates trust and pretense of trust, and (iii) cannot account for the rationality of back-up planning.

Strawson's view on punishment has been either neglected or recoiled from in contemporary scholarship on ‘Freedom and Resentment’ (FR). Strawson's alleged retributivism has made his view suspect and troublesome. In this article, we first argue, against the mainstream, that the punishment passage is an indispensable part of the main argument in FR (section 1) and elucidate in what sense Strawson can be called ‘a retributivist’ (section 2). We then elaborate our own hypothesis of symbolic retribution to explain the continuum between (...) moral reactive attitudes and punishment that Strawson only adumbrates (section 3). After this justification of the punitive response to wrongdoing, we compare and contrast our specific kind of retributivist hypothesis with other positions in the so-called ‘new retributivism’ (section 4). Our hypothesis differs from other subvarieties of expressive retributivism in putting centre stage the idea of punishment as taking up a reverential stance towards the victim. (shrink)

Since anonymous agents can spread misinformation with impunity, many people advocate for greater accountability for internet speech. This paper provides a veritistic argument that accountability mechanisms can cause significant epistemic problems for internet encyclopedias and social media communities. I show that accountability mechanisms can undermine both the dissemination of true beliefs and the detection of error. Drawing on social psychology and behavioral economics, I suggest alternative mechanisms for increasing the trustworthiness of internet communication.

Modern scientific knowledge is increasingly collaborative. Much analysis in social epistemology models scientists as self-interested agents motivated by external inducements and sanctions. However, less research exists on the epistemic import of scientists’ moral concern for their colleagues. I argue that scientists’ trust in their colleagues’ moral motivations is a key component of the rationality of collaboration. On the prevailing account, trust is a matter of mere reliance on the self-interest of one’s colleagues. That is, scientists merely rely on external compulsion (...) to motivate self-interested colleagues to be trustworthy collaborators. I show that this self-interest account has significant limitations. First, it cannot fully account for trust by relatively powerless scientists. Second, reliance on self-interest can be self-defeating. For each limitation, I show that moral trust can bridge the gap—when members of the scientific community cannot rely on the self-interest of their colleagues, they rationally place trust in the moral motivations of their colleagues. Case studies of mid-twentieth-century industrial laboratories and exploitation of junior scientists show that such moral trust justifies collaboration when mere reliance on the self-interest of colleagues would be irrational. Thus, this paper provides a more complete and realistic account of the rationality of scientific collaboration. (shrink)

The Pessimistic Induction over the history of science argues that because most past theories considered empirically successful in their time turn out to be not even approximately true, most present ones probably aren’t approximately true either. But why did past scientists accept those incorrect theories? Kyle Stanford’s ‘Problem of Unconceived Alternatives’ is one answer to that question: scientists are bad at exhausting the space of plausible hypotheses to explain the evidence available to them. Here, I offer another answer, which I (...) call the ‘Problem of Misleading Evidence.’ I argue that this proposal is, in important respects, superior to Stanford’s. (shrink)

Ignorance of one’s privileges and prejudices is an epistemic problem. While the sources of ignorance of privilege and prejudice are increasingly understood, less clarity exists about how to remedy ignorance. In fact, the various causes of ignorance can seem so powerful, various, and mutually reinforcing that studying the epistemology of ignorance can inspire pessimism about combatting socially constructed ignorance. I argue that this pessimism is unwarranted. The testimony of members of oppressed groups can often help members of privileged groups overcome (...) their ignorance. This paper argues that a particular type of speaker’s trust—hopeful trust—can motivate hearers to become cognizant of their privilege and prejudice. I argue that hopeful trust is a powerful way of eliciting trust-responsiveness that can be an effective mechanism for challenging privilege and prejudice. To make this case, I draw on case studies of online attempts to challenge ignorance. While the problems of testimonial injustice, defensi... (shrink)

This paper argues that trustworthiness is an epistemic virtue that promotes objectivity. I show that untrustworthy imposture can be an arrogant act of privilege that silences marginalized voices. But, as epistemologists of ignorance have shown, sometimes trickery and the betrayal of epistemic norms are important resistance strategies. This raises the question: when is betrayal of trust epistemically virtuous? After establishing that trust is central to objectivity, I argue for the following answer: a betrayal is epistemically vicious when it strengthens or (...) promotes oppressive, exclusive networks of trust, and a betrayal is epistemically virtuous when it expands trust networks to involve the oppressed. These criteria correctly account for both the epistemic vice of a recent case of Internet imposture and the epistemic virtue of resistant tricksters. (shrink)

Suppose one believes that the historical record of discarded scientific theories provides good evidence against scientific realism. Should one adopt Kyle Stanford’s specific version of this view, based on the Problem of Unconceived Alternatives? I present reasons for answering this question in the negative. In particular, Stanford’s challenge cannot use many of the prima facie strongest pieces of historical evidence against realism, namely: superseded theories whose successors were explicitly conceived, and superseded theories that were not the result of elimination-of-alternatives inferences. (...) Attempts to accommodate and within Stanford’s framework are incompatible with other commitments Stanford holds, such as anti-realism being piecemeal instead of global. As separate lines of criticism, I argue that there are problems with Stanford’s claim that the PUA is the most important challenge to realism, and with his view of instrumentalist theory endorsement.

Recent scholarship indicates that Quine’s “Truth by Convention” does not present the radical critiques of analytic truth found fifteen years later in “Two Dogmas of Empiricism.” This prompts a historical question: what caused Quine’s radicalization? I argue that two crucial components of Quine’s development can be traced to the academic year 1940–1941, when he, Russell, Carnap, Tarski, Hempel, and Goodman were all at Harvard together. First, during those meetings, Quine recognizes that Carnap has abandoned the extensional, syntactic approach to philosophical (...) analysis, an approach espoused in Carnap’s 1934 Logical Syntax of Language, and which Quine endorsed his entire career. Second, Tarski presents Quine with a philosophically well-motivated reason to think that an apparently analytic discipline, arithmetic, could be synthetic; this reflects one of the central assertions found in “Two Dogmas” but not in “Truth by Convention.” I use this account of Quine’s development to resolve a dispute between Creath and Mancosu concerning the timeline for Quine’s evolving critiques of analyticity.

Scientific anti-realists who appeal to the pessimistic induction (PI) claim that the theoretical terms of past scientific theories often fail to refer to anything. But on standard views in philosophy of language, such reference failures prima facie lead to certain sentences being neither true nor false. Thus, if these standard views are correct, then the conclusion of the PI should be that significant chunks of current theories are truth-valueless. But that is semantic anti-realism about scientific discourse—a position most philosophers of (...) science, anti-realists included, consider anathema today. Therefore, proponents of the PI confront a dilemma: either accept semantic anti-realism or reject common semantic views. I examine strategies (with particular emphasis on supervaluations) for the PI proponent to either lessen the sting of this argument, or learn to live with it. 1 Introduction2 Designation Failure 2.1 Designation failure leads to truth-valueless sentences2.1.1 Direct reference theory2.1.2 Fregeanism2.1.3 Accounts of reference-fixing: why ‘phlogiston’ fails to designate 2.2 Objection: sentences exhibiting designation failure are false not truth-valueless 2.3 Avoiding truth-valuelessness via controversial semantic positions3 What to do?

The underdetermination of theory by data obtains when, inescapably, evidence is insufficient to allow scientists to decide responsibly between rival theories. One response to would-be underdetermination is to deny that the rival theories are distinct theories at all, insisting instead that they are just different formulations of the same underlying theory; we call this the identical rivals response. An argument adapted from John Norton suggests that the response is presumptively always appropriate, while another from Larry Laudan and Jarrett Leplin suggests (...) that the response is never appropriate. Arguments from Einstein for the special and general theories of relativity may fruitfully be seen as instances of the identical rivals response; since Einstein’s arguments are generally accepted, the response is at least sometimes appropriate. But when is it appropriate? We attempt to steer a middle course between Norton’s view and that of Laudan and Leplin: the identical rivals response is appropriate when there is good reason for adopting a parsimonious ontology. Although in simple cases the identical rivals response need not involve any ontological difference between the theories, in actual scientific cases it typically requires treating apparent posits of the various theories as mere verbal ornaments or computational conveniences. Since these would-be posits are not now detectable, there is no perfectly reliable way to decide whether we should eliminate them or not. As such, there is no rule for deciding whether the identical rivals response is appropriate or not. Nevertheless, there are considerations that suggest for and against the response; we conclude by suggesting two of them. (shrink)

Many have tackled the question ‘What (if anything) is analytic philosophy?’ I will not attempt to answer this vexed question. Rather, I address a smaller, more manageable set of interrelated questions: first, when and how did people begin using the label ‘analytic philosophy’? Second, how did those who used this label understand it? Third, why did many philosophers we today classify as analytic initially resist being grouped together under the single category of ‘analytic philosophy’? Finally, for the first generation who (...) described themselves as analytic philosophers, what was their intended contrast class? Relatedly, when did ‘continental philosophy’ become the standard opposition? Some evidence I present justifies received answers to these questions; other evidence supports surprising and unorthodox answers to these questions. (shrink)

Confused terms appear to signify more than one entity. Carnap maintained that any putative name that is associated with more than one object in a relevant universe of discourse fails to be a genuine name. Although many philosophers have agreed with Carnap, they have not always agreed among themselves about the truth-values of atomic sentences containing such terms. Some hold that such atomic sentences are always false, and others claim they are always truth-valueless. Field maintained that confused terms can still (...) refer, albeit partially, and offered a supervaluational account of their semantic properties on which some atomic sentences with confused terms can be true. After outlining many of the most important theoretical considerations for and against various semantic theories for such terms, we report the results of a study designed to investigate which of these accounts best accords with the truth-value judgments of ordinary language users about sentences containing these terms. We found that naïve participants view confused names as capable of successfully referring to one or more objects. Thus, semantic theories that judge them to involve total reference failure do not comport well with patterns of ordinary usage. (shrink)

Many commentators on Alfred Tarski have, following Hartry Field, claimed that Tarski's truth-definition was motivated by physicalism—the doctrine that all facts, including semantic facts, must be reducible to physical facts. I claim, instead, that Tarski did not aim to reduce semantic facts to physical ones. Thus, Field's criticism that Tarski's truth-definition fails to fulfill physicalist ambitions does not reveal Tarski to be inconsistent, since Tarski's goal is not to vindicate physicalism. I argue that Tarski's only published remarks that speak approvingly (...) of physicalism were written in unusual circumstances: Tarski was likely attempting to appease an audience of physicalists that he viewed as hostile to his ideas. In later sections I develop positive accounts of: (1) Tarski's reduction of semantic concepts; (2) Tarski's motivation to develop formal semantics in the particular way he does; and (3) the role physicalism plays in Tarski's thought.

The Pessimistic Induction (PI) states: most past scientific theories were radically mistaken; therefore, current theories are probably similarly mistaken. But mistaken in what way? On the usual understanding, such past theories are false. However, on widely held views about reference and presupposition, many theoretical claims of previous scientific theories are neither true nor false. And if substantial portions of past theories are truth-valueless, then the PI leads to semantic antirealism. But most current philosophers of science reject semantic antirealism. So PI (...) proponents face a difficult choice: accept either semantic antirealism or an unorthodox position on reference and presupposition. (shrink)

The logic of singular terms that refer to nothing, such as ‘Santa Claus,’ has been studied extensively under the heading of free logic. The present essay examines expressions whose reference is defective in a different way: they signify more than one entity. The bulk of the effort aims to develop an acceptable formal semantics based upon an intuitive idea introduced informally by Hartry Field and discussed by Joseph Camp; the basic strategy is to use supervaluations. This idea, as it stands, (...) encounters difficulties, but with suitable refinements it can be salvaged. Two other options for a formal semantics of multiply signifying terms are also presented, and I discuss the relative merits of the three semantics briefly. Finally, possible modifications to the standard logical regimentation of the notion of existence are considered. (shrink)

Peter Strawson makes a crucial distinction between reactive attitudes and the objective attitude. Reactive attitudes such as gratefulness, anger and indignation imply that we take each other seriously as responsible agents. The objective attitude implies that we stop taking each other seriously. Strawson argues that the objective attitude is not merely psychologically difficult: it is inconceivable that we would systematically refrain from taking each other seriously and stop discussing with each other or blaming ourselves or others. Strawson, however, only discusses (...) the reactive attitudes from a general point of view. In this paper, we argue that the reactive attitudes of remorse and moral indignation are forms of ”symbolic restoration’. Retributive punishment should also be interpreted from this perspective. Consequently, our concern with moral blame cannot be understood independently from a concern with the harm that has occurred. Our attitude to the outcome determines our attitude to the agent. The concern with the mental state is secondary: it is structured by its place within the practice of symbolic restoration. (shrink)

Utopianism aims at a global transformation in virtue of which both the external world and our own reality will develop in such ways as to be in greater harmony with our wishes. What utopianism does not take into account, however, is the existence of two important kinds of desire. In the first place, human beings have the need to react symbolically to what cannot be changed. In the second place, they also have a desire for recognition and for a significant (...) life. With these desires, human beings have aims that go beyond morality’s protective ideals. Offering the example of transhumanism as a paradigm case of utopianism in our own days, the present article illustrates how utopianism ignores the fact that human beings indirectly desire that certain of their objects of desire remain beyond their control.

In Physics 4.11, Aristotle says that changes are continuous because magnitude is continuous. I suggest that this is not Aristotle’s considered view, and that in Generation and Corruption 2.10 Aristotle argues that this leads to the unacceptable consequence that alterations can occur discontinuously. Physics 6.4 was written to amend this theory, and to argue that changes are continuous because changing bodies are so. I also discuss the question of Aristotle’s consistency on the possibility of discontinuous alterations, such as freezing.
