A general introduction by John Dillon. An annotated Russian translation of theIntroduction to Arithmetic and Manual of Harmonics by Neopythagorean philosopher Nicomachus of Gerasa, prepared by Andrej Schetnikov [Introduction], Timothy Myakin, and Ludmila Alexandrova [Manual]. These short treatises, important for the history of ancient mathematics and musical theory, is completely translated into Russian for the first time.

What does 'if' mean? Timothy Williamson presents a controversial new approach to understanding conditional thinking, which is central to human cognitive life. He argues that in using 'if' we rely on psychological heuristics, fast and frugal methods which can lead us to trust faulty data and prematurely reject simple theories.

Two opposing tendencies in the philosophy of language go by the names of ‘referentialism’ and ‘inferentialism’ respectively. In the crudest version of the contrast, the referentialist account of meaning gives centre stage to the referential semantics for a language, which is then used to explain the inference rules for the language, perhaps as those which preserve truth on that semantics (since a referential semantics for a language determines the truth-conditions of its sentences). By contrast, the inferentialist account of meaning gives (...) centre stage to the inference rules for the language, which are then used to explain its referential semantics, perhaps as the semantics on which the rules preserve truth. On pain of circularity, we cannot combine both directions of explanation. (shrink)

Improbable knowing is knowing something even though it is almost certain on one’s evidence at the time that one does not know that thing. Once probabilities on the agent’s evidence are introduced into epistemic logic in a very natural way, it is easy to construct models of improbable knowing, some of which have realistic interpretations, for instance concerning agents like us with limited powers of perceptual discrimination. Improbable knowing is an extreme case of failure of the KK principle, that is, (...) of a case of knowing something even though one does not know at the time that one knows that thing. A generalization of the argument yields cases of improbable rationality, in which it is rational for one to do something even though it is almost certain on one’s evidence at the time that it is not rational for one to do that thing. When the models are elaborated to represent appearances and beliefs as well as knowledge, they turn out to contain Gettier cases. Neglect of the possibility of improbable knowing may cause some sceptical claims and claims of the non-closure of knowledge under competent deduction to look more plausible than they deserve to. A formal appendix explores the closely related question of the conditions under which a reflection principle is violated. The principle says that the evidential probability of a proposition conditional on the evidential probability of that proposition’s being c is itself c. (shrink)

Abstract: Some proponents of “experimental philosophy” criticize philosophers' use of thought experiments on the basis of evidence that the verdicts vary with truth-independent factors. However, their data concern the verdicts of philosophically untrained subjects. According to the expertise defence, what matters are the verdicts of trained philosophers, who are more likely to pay careful attention to the details of the scenario and track their relevance. In a recent article, Jonathan M. Weinberg and others reply to the expertise defence that there (...) is no evidence for such expertise. They now receive a reply in this article, which argues that they have misconstrued the dialectical situation. Since they have produced no evidence that philosophical training is less efficacious for thought experimentation than for other cognitive tasks for which they acknowledge that it produces genuine expertise, such as informal argumentation, they have produced no evidence for treating the former more sceptically than the latter.

Assertions are praised as true, informative, relevant, sincere, warranted, well-phrased, or polite. They are criticized as false, uninformative, irrelevant, insincere, unwarranted, ill-phrased, or rude. Sometimes they deserve such praise or criticism. If any respect in which performances of an act can deserve praise or criticism is a norm for that act, then the speech act of assertion has many norms. So has almost any act; jumps can deserve praise as long or brave, criticism as short or cowardly. But it is (...) natural to suppose that some norms are more intimately connected to the nature of asserting than any norm is to the nature of jumping. One might suppose, for example, that someone who knowingly asserts a falsehood has thereby broken a rule of assertion, much as if he had broken a rule of a game; he has cheated. On this view, the speech act, like a game and unlike the act of jumping, is constituted by rules. Thus, not all norms for assertion are on a par. Norms such as relevance, good phrasing, and politeness are just applications of more general cognitive or social norms to the specific act of assertion. Perhaps the norm of informativeness results from a more complex interaction between a general norm of cooperativeness and the nature of assertion as a source of information. But on this view, not all norms for assertion derive from more general norms; otherwise nothing would differentiate it from other speech acts. (shrink)

Is philosophy a unique discipline, or are its methods more like those of other sciences than many philosophers think? Timothy Williamson explains clearly and concisely how contemporary philosophers think and work, and reflects on their powers and limitations.

We discuss three varieties of affective dynamics. In each case, we suggest how these affective dynamics should be operationalized and measured in daily life using time-intensive methods, like ecological momentary assessment or ambulatory assessment, and recommend time-sensitive analyses that take into account not only the variability but also the temporal dependency of reports. Studies that explore how these affective dynamics are associated with psychological disorders and symptoms are reviewed, and we emphasize that these affective processes are within a nexus of (...) other components of emotion regulation.

The harms associated with wireless mobile devices (e.g. smartphones) are well documented. They have been linked to anxiety, depression, diminished attention span, sleep disturbance, and decreased relationship satisfaction. Perhaps what is most worrying from a moral perspective, however, is the effect these devices can have on our autonomy. In this article, we argue that there is an obligation to foster and safeguard autonomy in ourselves, and we suggest that wireless mobile devices pose a serious threat to our capacity to fulfill (...) this obligation. We defend the existence of an imperfect duty to be a ‘digital minimalist’. That is, we have a moral obligation to be intentional about how and to what extent we use these devices. The empirical findings already justify prudential reasons in favor of digital minimalism, but the moral duty is distinct from and independent of prudential considerations. (shrink)

Broadly speaking, the contemporary scientific realist is concerned to justify belief in what we might call theoretical truth, which includes truth based on ampliative inference and truth about unobservables. Many, if not most, contemporary realists say scientific realism should be treated as ‘an overarching scientific hypothesis’ (Putnam 1978, p. 18). In its most basic form, the realist hypothesis states that theories enjoying general predictive success are true. This hypothesis becomes a hypothesis to be tested. To justify our belief in the (...) realist hypothesis, realists commonly put forward an argument known as the ‘no-miracles argument’. With respect to the basic hypothesis this argument can be stated as follows: it would be a miracle were our theories as successful as they are, were they not true; the only possible explanation for the general predictive success of our scientific theories is that they are true.

The author argues that all forms of life are interconnected and that no being, construct, or object can exist independently from the ecological entanglement, nor does "nature" exist as an entity separate from the uglier or more synthetic elements of life. Realizing this interconnectedness is what the author calls the ecological thought. He investigates the philosophical, political, and aesthetic implications of this interconnectedness.

Critics of persuasive advertising argue that it undermines the autonomy of consumers by manipulating their desires in morally problematic ways. My aim is this paper is to refine that argument by employing a conception of autonomy that is not at odds with certain forms of manipulation. I argue that the charge of manipulation is not sufficient for condemning persuasive advertising. On my view, manipulation of an agent’s desires through advertising is justifiable in cases where the agent accepts the process through (...) which the desires were developed. I show how the standard manipulation objection proves too much as it would also condemn cases of that kind. I argue that this distinction is especially important when we consider the implications of “new media.” In addition to increasing vulnerability to manipulation, new media have considerable impacts on well-being. By siding with the traditional autonomy argument, we would be compelled to take an implausible stand against all forms of manipulation through advertising, but I suggest that only a proper subset of those cases are morally problematic. This conclusion opens up a space for persuasive advertising that is permissible while nevertheless condemning cases that violate consumers’ autonomy. (shrink)

Four people with radically different views meet on a train and talk about what they believe. Each starts off convinced that he or she is right; then doubts creep in. Timothy Williamson uses a fictional conversation to explore the philosophical debate over whether one point of view can be right and the other wrong. He invites the reader to decide.

A striking feature of the traditional armchair method of philosophy is the use of imaginary examples: for instance, of Gettier cases as counterexamples to the justified true belief analysis of knowledge. The use of such examples is often thought to involve some sort of a priori rational intuition, which crude rationalists regard as a virtue and crude empiricists as a vice. It is argued here that, on the contrary, what is involved is simply an application of our general cognitive capacity (...) to handle counterfactual conditionals, which is not exclusively a priori and is not usefully conceived as a form of rational intuition. It is explained how questions of metaphysical possibility and necessity are equivalent to questions about counterfactuals, and the epistemology of the former (in particular, the role of conceiving or imagining) is a special case of the epistemology of the latter. A non-imaginary Gettier case is presented in order to show how little difference it makes. (shrink)

The paper criticizes epistemological conceptions of analytic or conceptual truth, on which assent to such truths is a necessary condition of understanding them. The critique involves no Quinean scepticism about meaning. Rather, even granted that a paradigmatic candidate for analyticity is synonymy with a logical truth, both the former and the latter can be intelligibly doubted by linguistically competent deviant logicians, who, although mistaken, still constitute counterexamples to the claim that assent is necessary for understanding. There are no analytic or (...) conceptual truths in the epistemological sense. The critique is extended to purportedly analytic inference rules. An alternative account is sketched on which understanding a word is a matter of participation in a linguistic practice, while synonymy and concept identity consist in sameness of truth-conditional semantic properties. Although there are philosophical questions about concepts, the idea that philosophical questions in general are conceptual questions generates only an illusion of insight into philosophical methodology.

In this paper, I give an explanation and defense of Kant’s claim that we cannot comprehend how freedom is possible. I argue that this is a significant point that has been underappreciated in the secondary literature. My conclusion has a variety of implications both for Kant scholars and for those interested in Kantian ideas more generally. Most notably, if Kant is right that there are principled reasons why freedom is beyond our comprehension, then this would release his ethical views from (...) an undesirable explanatory burden. It would be a boon for Kantians if they could ground their lofty claims about the unique, elevated status of rational agency without committing to an implausible view of libertarian freedom. I also suggest that there are certain debates concerning moral motivation and transcendental idealism that might have to change in response to Kant’s claims about the incomprehensibility of freedom.

In the paper, titled ‘Choosing death in unjust conditions: hope, autonomy and harm reduction,’ Wiebe and Mullin argue that people living in unjust social conditions are sufficiently autonomous to request medical assistance in dying (MAiD). The ethical issue is that some people may request MAiD primarily because of unjust social conditions, not their illness, disease, disability or decline in capability. It is easily agreed that people living in unjust social conditions can be autonomous. Nevertheless, Wiebe and Mullin fail to appreciate (...) that autonomy is only a necessary condition for MAiD. In addition to autonomy, one must decide that providing assisted dying to a patient because they are living in unjust social conditions is ethical. Central to making this ethical decision is the principle of non-maleficence, famously articulated as ‘do no harm.’ The authors admit that performing MAiD in response to unjust social circumstances is harmful, but they justify this harmful action by appealing to the principle of harm reduction. A fundamental flaw of their approach is that it relies on the legislative definition of intolerable suffering, which is based on circular reasoning and given that 99.2% of patients that have applied for MAiD satisfied this criterion, it is essentially equivalent to no standard/criterion. Canadian society is struggling with the ethical implications of its permissive MAiD programme, and, fundamental to this debate, will be determining the proper balance between autonomy and non-maleficence for people living in unjust social conditions.

The paper outlines and explores a possible strategy for defending both the action/omission distinction and the principle of double effect. The strategy is to argue that there are degrees of actionhood, and that we are in general less responsible for what has a lower degree of actionhood, because of that lower degree. Moreover, what we omit generally has a lower degree of actionhood than what we actively do, and what we do under known-but-not-intended descriptions generally has a lower degree of (...) actionhood than what we do under known-and-intended descriptions. Therefore, we are in general less responsible for what we omit than for what we do—which is just what AOD says. And we are in general less responsible for what we do under known-but-not-intended descriptions than for what we do under known-and-intended descriptions—which is just what PDE says. (shrink)

If anti-realism is defined as the principle that all truths are knowable, then anti-realists have a reason to revise logic. For an argument first published by Fitch seems to reduce anti-realism to absurdity within classical but not constructivist logic. One might try to sever this link between anti-realism and revisionism in logic by giving either a modified version of anti-realism not vulnerable to Fitch's argument within classical logic or a modified version of Fitch's argument to which anti-realism is vulnerable within (...) constructivist logic.

This chapter contains sections titled: The concept of phenomenal character is closely related to that of a phenomenal quality. If phenomenal characters are just maximally specific phenomenal qualities, it would follow that there are no phenomenal characters either. The first section gives reasons for fearing that observational predicates are susceptible to sorites paradoxes, but denies that predicates such as “painful” are perfectly observational. They are instead phenomenal, in a sense developed in the second section. The third section considers and rejects (...) a final attempt to revive a sorites paradox for painful. The fourth section tentatively places these thoughts against a background of a general account of sorites paradoxes, on which they may reflect either speakers' ignorance or semantic indeterminacy or both, depending on the facts of the particular case. The arguments of this chapter therefore have parallels for the paradox of small numbers. (shrink)

According to standard scientific realism, science seeks truth and we can justifiably believe that our successful theories achieve, or at least approximate, that goal. In this paper, I discuss the implications of the following competitor thesis: Any theory we may favor has competitors such that we cannot justifiably deny that they are approximately true. After defending that thesis, I articulate three specific threats it poses for standard scientific realism; one is epistemic, the other two are axiological (that is, pertaining to (...) the claim that science seeks truth). I also flag an additional axiological “challenge,” that of how one might justify the pursuit of a primary aim, such as truth. Bracketing epistemic realism, I argue that the axiological threats can be addressed by embracing a refined realist axiological hypothesis, one that specifies a specific subclass of true claims sought in science. And after identifying three potential responses to the axiological “challenge,” I contend that, while standard axiological realism appears to lack the resources required to utilize any of the responses, the refined realist axiology I embrace is well suited to each.

Carruthers argues that knowledge of our own propositional attitudes is achieved by the same mechanism used to attain knowledge of other people's minds. This seems incompatible with "privileged access"---the idea that we have more reliable beliefs about our own mental states, regardless of the mechanism. At one point Carruthers seems to suggest he may be able to maintain privileged access, because we have additional sensory information in our own case. We raise a number of worries for this suggestion, concluding that (...) Carruthers's new theory cannot clearly preserve the superior reliability of our beliefs about our own attitudes. (shrink)

In this global introduction to philosophy of religion you begin not with a single tradition, but with religious philosophies from East Asia, South Asia, West Africa, and Native North America, alongside the classical Abrahamic and modern European traditions. Matching this diversity of traditions, chapters are organized around questions that acknowledge there is no single understanding of any god or ultimate reality. Instead you approach six different traditions of philosophizing about religion by asking questions about the journeys of both the self (...) and the cosmos such as "What is my path?" and "Where did the cosmos come from?" Accompanied by introductory materials and an extensive glossary, each chapter includes learning objectives, questions for discussion, and suggested primary and secondary sources. The categories of religion and philosophy are interrogated throughout. Equipped with study tools and universal questions about the self and the cosmos, Philosophies of Religion: A Global and Critical Introduction shows you how to philosophize about religions around the world.

This book presents in translation writings by six medieval philosophers which bear on the subject of conscience. Conscience, which can be considered both as a topic in the philosophy of mind and a topic in ethics, has been unduly neglected in modern philosophy, where a prevailing belief in the autonomy of ethics leaves it no natural place. It was, however, a standard subject for a treatise in medieval philosophy. Three introductory translations here, from Jerome, Augustine and Peter Lombard, present the (...) loci classici on which subsequent discussions drew; there follows the first complete treatise on conscience, by Philip the Chancellor, while the two remaining translations, from Bonaventure and Aquinas, have been chosen as outstanding examples of the two main approaches which crystallised during the thirteenth century.

The influential public health ethics framework proposed by Childress et al. includes five “justificatory conditions,” two of which are “necessity” and “least infringement.” While the framework points to important moral values, we argue it is redundant for it to list both necessity and least infringement because they are logically equivalent. However, it is ambiguous whether Childress et al. would endorse this view, or hold the two conditions distinct. This ambiguity has resulted in confusion in public health ethics discussions citing the (...) Childress et al. framework, as demonstrated by debate between Resnik and Wilson and Dawson. We analyse this debate to resolve these ambiguities. Finally, we argue that the necessity/least infringement principle of the Childress et al. framework applies only in cases in which only one intervention is to be implemented to achieve one specific goal. In other cases, it is not essential to require that only the least infringing intervention be implemented. (shrink)

Can some contingent truths be known a priori?: when this question is raised in modern philosophy — as, following Kripke, it often has been — it generally introduces a discussion of certain examples which seem to turn on indexical or indexical-like words . Sometimes the indexicality is quite obvious, as in 'I am here now', sometimes it appears only on analysis, as in 'If anyone uniquely invented the zip, Julius did', where by stipulation 'Julius' rigidly designates the inventor of the (...) zip , for the rigidity of 'Julius' can be expressed by means of the 'actually' operator, which is at least formally analogous to an indexical . Moreover, this indexicality has been exploited in a well known argument that what is known a priori can be contingent only in a superficial way pp. 161-89; technical details are omitted, since deep and superficial contingency coincide for sentences, such as those considered below, without 'actually' or similar operators). The purpose of this note is to argue that there are deeply contingent a priori truths which in no way turn on indexicals. I do not deny that there are also contingent a priori truths which do turn on indexicals, but we are unlikely to get clear on the contingent a priori in-general if we take it to be essentially tied up with indexicals when in fact it is not.
