Scholars often assert that Plato and Aristotle share the view that discursive thought is internal speech. However, there has been little work to clarify or substantiate this reading. In this paper I show Plato and Aristotle share some core commitments about the relationship of thought and speech, but cash out TIS in different ways. Plato and Aristotle both hold that discursive thinking is a process that moves from a set of doxastic states to a final doxastic state. The resulting judgments (...) can be true or false. Norms govern these final judgments and, in virtue of that, they govern the process that arrives at those judgments. The principal norm is consistency. However, the philosophers differ on the source of this norm. For Plato, persuasiveness and accuracy ground non-contradiction because internal speech is dialogical. For Aristotle, the Principle of Non-Contradiction grounds a Doxastic Thesis that no judgment can contradict itself. For Aristotle, metaphysics grounds non-contradiction because internal speech is monological. (shrink)

Sophist 255c14 distinguishes καθ’ αὑτά and πρὸς ἄλλα (in relation to others). Many commentators identify this with the ‘absolute’ and ‘relative’ category distinction. However, terms such as ‘same’ cannot fit into either category. Several reliable manuscripts read πρὸς ἄλληλα (in relation to each other) for πρὸς ἄλλα. I show that πρὸς ἄλληλα is a palaeographically plausible reading which accommodates the problematic terms. I then defend my reading against objections.

Abstractabstract:Diodorus Cronus reportedly denied that there are truths about present kinēsis (change or movement) but affirmed that there are truths about past kinēsis. Although scholars have argued that Diodorus's atomism about bodies, place, and time supports his rejection of present spatial movement of simple bodies, I argue that Diodorus rejected a broader range of present changes, including qualitative and existential change. I also argue that Diodorus rejected these three sorts of change not only for simples but also for complexes. Furthermore, (...) philosophers since antiquity have claimed that denying truths about present change is incompatible with accepting truths about past change, since each past truth about change corresponds to some present truth about change. I argue that this objection can be overcome. I conclude that Diodorus's arguments against present change are both broader and more successful than is usually maintained. (shrink)

This book explores how ancient philosophers, particularly Plato, Aristotle, the Stoics, and Sextus Empiricus, understood relativity and how their theories of the phenomenon affected, and were affected by, their broader philosophical outlooks.

AtCategories7, 6a36-7 Aristotle defines relatives, but at 8a13-28 worries that the definition may include some substances. Aristotle introduces a second account of relatives to solve the problem. Recent commentators have held that Aristotle intends to solve the extensional adequacy worry by restricting the extension of relatives. That is, R2 counts fewer items as relative than R1. However, this cannot explain Aristotle’s attitude to relatives, since he immediately returns to using R1. I propose a non-extensional reading. R1 and R2 do not (...) specify different sets of relatives, but rather different ways to understand each relative. (shrink)

A relative change occurs when some item changes a relation. This Element examines how Plato, Aristotle, Stoics and Sextus Empiricus approached relative change. Relative change is puzzling because the following three propositions each seem true but cannot be true together: No relative changes are intrinsic changes; Only intrinsic changes are proper changes; Some relative changes are proper changes. Plato's Theaetetus and Phaedo property relative change. I argue that these dialogues assume relative changes to be intrinsic changes, so denying. Aristotle responds (...) differently, by denying that relative change is proper change. The Stoics claimed that some non-intrinsic changes are changes ). Finally, I discuss Sextus' argument that relative change shows that there are no relatives at all. (shrink)

ABSTRACT McCabe [2021: 137–40] identifies a crucial ambiguity in the terms ‘learns’ and ‘knows’. Such terms can be read as either ‘perfective’ or ‘imperfective’. This is an aspect difference. The former indicates a settled state, the latter a directed process. McCabe uses this insight to show how Socrates can rebut the sophists’ view of meaning, render compelling Socrates’ self-refutation arguments, and explain the Socratic connections between learning, knowledge, and how one should live. In the final section of the Euthydemus, Euthydemus (...) offers the ‘Omniscience Sophism’, and the related, rather cheeky, ‘Father Sophisms’. McCabe [ibid.: 140–2] suggests that the Omniscience Sophism might be addressed by identifying an aspect ambiguity, but does not follow up her point in detail. In this response, I argue that McCabe’s instinct is good and that a relative term, such as ‘knowledgeable’, can be understood as having two senses. That distinction is between what I call ‘fine-grained’ and ‘coarse-grained’ senses of ‘knowledgeable’. I suggest that this distinction that tracks McCabe’s aspect distinction between senses of ‘learns’ and best explains the fallacy committed in the Omniscience Sophism. (shrink)

(1) If a deductive argument is valid, then the conclusion is not novel. (2) If the conclusion of an argument is not novel, the argument is not useful. So, (3) if a deductive argument is valid, it is not useful. This conclusion, (3), is unacceptable. Since the argument is valid, we must reject at least one premise. So, should we reject (1) or (2)? This puzzle is usually known as the ‘scandal of deduction’. Analytic philosophers have tried to reject (1) (...) but have assumed premise (2). I argue here that Aristotle would deny (2). Aristotle thinks that at least some deductive arguments are useful, even though they present no new conclusions. Thus, Aristotle’s view contrasts with analytic philosophers of logic, who assume that all useful deductive arguments present novel conclusions. I don’t claim that Aristotle ‘solves’ the problem: it was never posed in Aristotle’s time. Rather, I suggest that Aristotle does not face the problem because he assumes deductions can be useful, without presenting novel conclusions. Aristotle’s view of deduction tames the scandal.

In Metaphysics Theta 3 Aristotle attributes to the Megarics and unknown others a notorious modal thesis: (M) something can φ only if it is φ-ing. Aristotle does not tell us what motivated (M). Almost all scholars take Aristotle’s report to indicate that the Megarics defended (M) as a highly counterintuitive doctrine in modal metaphysics. But this reading faces several problems. First: what would motivate the Megarics to hold such a counterintuitive view? The existing literature tries, in various ways, to motivate (...) (M) in a way neither trivial nor absurd. But, as we will argue, the main approaches end up attributing an unsustainable position to the Megarics. Second: most historical evidence for the Megaric lineage presents the group’s philosophical practice as dialectical or negative. So why think that the claim reported in Theta 3 presents a positive, and highly controversial, metaphysical claim? This paper addresses these problems by proposing a dialectical (or negative) reading of the Megarics in Theta 3. By ‘dialectical’ we here mean a mode of philosophizing that neither seeks to establish the truth or falsity of certain theses, nor takes a skeptical stance. There are different reasons why a philosopher might want to take up such a mode; in the case of the Megarics we argue that they might have wanted to put pressure on Aristotle’s idea of possibility and the ‘test’ for possibility that Aristotle mentions in several works. Reading, as we do, (M) as (part of) a paradox about possibility and actuality, we argue that the Megarics’ dialectical approach here aims to highlight a shortcoming of an intuitive conception of possibility, which underpins Aristotle’s idea of possibility and which features in his test for possibility.

Infinite regress arguments are a powerful tool in Aristotle, but this style of argument has received relatively little attention. Improving our understanding of infinite regress arguments has become pressing since recent scholars have pointed out that it is not clear whether Aristotle’s infinite regress arguments are, in general, effective or indeed what the logical structure of these arguments is. One obvious approach would be to hold that Aristotle takes infinite regress arguments to be per impossibile arguments, which derive an infinite (...) sequence. Due to his finitism, Aristotle then rejects such a sequence as impossible. This paper argues that this obvious approach does not work, even for its most amenable cases. The paper argues instead that infinite regress arguments involve domain-specific infinities, and so there is not a general finitism which underpins infinite regress arguments in Aristotle, but rather domain-specific reasons that there cannot be an infinite number of entities in each domain in which Aristotle invokes an infinite regress argument.

In this book, Matthew Duncombe argues that Plato, Aristotle, certain Stoics, and Sextus Empiricus each held a broadly "constitutive" view of relativity. According to constitutive accounts, a "relative" is constituted by the relation that it bears to its "correlative". Such treatments of relativity sharply contrast with more familiar nonconstitutive accounts, according to which standing in some relation suffices for being a relative. On such a view, versions of which many scholars have assumed to be at work in antiquity, (...) Alcibiades counts as a relative because he is related to Socrates through the "is more beautiful than" relation. On... (shrink)

Suppose we consider knowledge to be valuable because of the role known propositions play in practical reasoning. This, I argue, does not provide a reason to think that knowledge is valuable in itself. Rather, it provides a reason to think that true belief is valuable from one standpoint, and that justified belief is valuable from another standpoint, and similarly for other epistemic concepts. The value of the concept of knowledge is that it provides an economical way of talking about many (...) epistemic concepts that are valuable in itself from one standpoint or another. In this way knowledge is like a Swiss Army Knife; a Swiss Army Knife is not useful as such on any occasion, but it provides an efficient way of carrying around different tools that are useful in themselves on different occasions.

Postcolonial science studies entails ostensibly contradictory critical and empirical commitments. Science studies scholars influenced by Bruno Latour and Isabelle Stengers embrace forms of realist, radical empiricism, while postcolonial studies scholars influenced by Jacques Derrida trace the limits of the knowable. This essay takes their common use of the term cosmopolitics as an unexpected point of departure for reconciling Derrida’s program with Stengers’s and Latour’s. I read Derrida’s critique of hospitality and Stengers’s and Latour’s ontological politics as necessary complements for conceiving (...) a care-oriented subalternist cosmopolitics, a process of composing common worlds that remains attentive to the limits of representation.

In Plato’s Symposium, the mysterious Apollodorus recounts to an unnamed comrade, and to us, Aristodemus’ story of just what happened at Agathon’s drinking party. Since Apollodorus did not attend the party, however, it is unclear what relevance he could have to our understanding of Socrates’ speech, or to the Alcibiadean “satyr and silenic drama” (222d) that follows. The strangeness of Apollodorus is accentuated by his recession into the background after only two Stephanus pages. What difference—if any—does Apollodorus make to the (...) Symposium? Does his inclusion call the dramatic and philosophical unity of the work into question? I argue that despite initial appearances, Plato has important philosophical reasons for including Apollodorus as a character. Far from being an odd appendage to an otherwise complete narrative, the figure of Apollodorus is useful for our understanding of Socrates’s conception of eros later in the work. (shrink)

In Nicomachean Ethics X.7–8, Aristotle defends a striking view about the good for human beings. According to Aristotle, the single happiest way of life is organized around philosophical contemplation. According to the narrowness worry, however, Aristotle's contemplative ideal is unduly Procrustean, restrictive, inflexible, and oblivious of human diversity. In this paper, I argue that Aristotle has resources for responding to the narrowness worry, and that his contemplative ideal can take due account of human diversity.

Is the cultural evolution of morality fairly contingent? Could cultural evolution have easily led humans to moral norms and judgments that are mostly false by our present lights? If so, does it matter philosophically? Yes, or so we argue. We empirically motivate the contingency of cultural evolution and show that it makes two major philosophical contributions. First, it shows that moral objectivists cannot explain the reliability of our moral judgments and thus strengthens moral debunking arguments. Second, it shows that the (...) reliability of our moral judgments is evidence for theism over metaphysical naturalism. (shrink)

What are the epistemological implications of the cognitive science of religion (CSR)? The lion’s share of discussion fixates on whether CSR undermines (or debunks or explains away) theistic belief. But could the field offer positive support for theism? If so, how? That is our question. Our answer takes the form of an evidential argument for theism from standard models and research in the field. According to CSR, we are naturally disposed to believe in supernatural agents and these beliefs are constrained (...) in certain ways. The three main theories of this supernatural disposition are byproduct theories, adaptationist theories, and hybrid theories. We argue that our supernatural disposition—as understood by any of the main theories—is more surprising and improbable given naturalism than theism and thus serves as evidence for theism over naturalism.

Conspiracy theories are a popular topic of conversation in everyday life but are often frowned upon in academic discussions. Looking at the recent spate of philosophical interest in conspiracy theories, The Philosophy of Conspiracy Theories looks at whether the assumption that belief in conspiracy theories is typically irrational is well founded.

Artistic activism intervenes in, and through, culture to animate ideas with emotions—charge them with affect—to motivate action, and change material conditions. Artistic activism also animates lived experience through emotions and, through its representation, gives rise to ideas and ideals. Yet we have no theory of change for how this might work. This article provides a model to think through and reflect upon “artistic activism,” or whatever name it goes by, as a complex practice that combines the affective power of the (...) arts with the effective aims of activism. This gives us a wide-angle lens with which to see how artistic activism might create change. The model is then applied to a real-world creative activism example: the Undocubus, an intervention by young undocumented immigrants in the southern United States. The model’s macro view aids with thinking through and assessing more specific and necessarily contextual micro theories of change that are applied, consciously or unconsciously, by artistic activists and those they work with. The applied micro-view tests out its alignment with an example of practice. Most importantly, a comprehensive theory of change for artistic activism can provide clarity and direction as to where to intervene to maximize change. (shrink)

On the one hand, Hume accepts the view -- which he attributes primarily to Stoicism -- that there exists a determinate best and happiest life for human beings, a way of life led by a figure whom Hume calls "the true philosopher." On the other hand, Hume accepts that view -- which he attributes to Scepticism -- that there exists a vast plurality of good and happy lives, each potentially equally choiceworthy. In this paper, I reconcile Hume's apparently conflicting commitments: (...) I argue that Hume's "Sceptical" pluralism about the character of the happiest life need not conflict with his "Stoic" advocacy of the supreme happiness of the true philosopher, given Hume's flexible understanding of how one might live as a true philosopher.

I issue a challenge for the view that deciding‐to‐A is rendered intentional by an intention or other pro‐attitude towards deciding. Either such an attitude cannot rationalize my deciding specifically to A for a reason I take to support doing A, or, fixing for this, cannot accommodate deciding without entertaining alternatives. If successful, the argument motivates the search for an account that does not source the intentionality of deciding in a rationalizing pro‐attitude.

This paper attempts to explain what a protest is by using the resources of speech-act theory. First, we distinguish the object, redress, and means of a protest. This provided a way to think of atomic acts of protest as having dual communicative aspects, viz., a negative evaluation of the object and a connected prescription of redress. Second, we use Austin’s notion of a felicity condition to further characterize the dual communicative aspects of protest. This allows us to distinguish protest from (...) some other speech acts which also involve a negative evaluation of some object and a connected prescription of redress. Finally, we turn to Kukla and Lance’s idea of a normative functionalist analysis of speech acts to advance the view that protests are a complex speech act constituted by dual input normative statuses and dual output normative statuses.

Traditionally, Aristotle is held to believe that philosophical contemplation is valuable for its own sake, but ultimately useless. In this volume, Matthew D. Walker offers a fresh, systematic account of Aristotle's views on contemplation's place in the human good. The book situates Aristotle's views against the background of his wider philosophy, and examines the complete range of available textual evidence. On this basis, Walker argues that contemplation also benefits humans as perishable living organisms by actively guiding human life activity, (...) including human self-maintenance. Aristotle's views on contemplation's place in the human good thus cohere with his broader thinking about how living organisms live well. A novel exploration of Aristotle's views on theory and practice, this volume will interest scholars and students of both ancient Greek ethics and natural philosophy. It will also appeal to those working in other disciplines including classics, ethics, and political theory. (shrink)

This book addresses a range of relevant theoretical issues, including the possibility of an interpersonally comparable measure of well-being, or “utility” metric; the moral value of equality, and how that bears on the form of the social welfare function; social choice under uncertainty; and the possibility of integrating considerations of individual choice and responsibility into the social-welfare-function framework. This book also deals with issues of implementation, and explores how survey data and other sources of evidence might be used to calibrate (...) both a utility metric and a social welfare function, and whether distributive goals are ever best pursued through regulation rather than the tax system. In working through this range of theoretical and practical issues, the book draws from a wide variety of literatures, including philosophical scholarship on equality, responsibility, the nature of well-being, and personal identity over time; the social choice literature within economics; applied economic literatures concerning the measurement of inequality and poverty; legal and policy-analysis scholarship on cost-benefit analysis, environmental justice, and the choice between regulation and taxation; and the burgeoning field of “happiness studies”.

This chapter offers a complete account of Aristotle’s underexplored treatment of the virtue of wittiness (eutrapelia) in Nicomachean Ethics IV.8. It addresses the following questions: (1) What, according to Aristotle, is this virtue and what is its structure? (2) How do Aristotle’s moral psychological views inform Aristotle’s account, and how might Aristotle’s discussions of other, more familiar virtues, enable us to understand wittiness better? In particular, what passions does the virtue of wittiness concern, and how might the virtue (and its (...) attendant vices) be related to the virtue of temperance (and its attendant vices)? (3) How does wittiness, as an ethical virtue, benefit its possessor? (4) How can Aristotle resolve some key tensions that his introducing a virtue of wittiness apparently generates for his ethics? In addition to exploring these questions, this chapter challenges some commonly accepted accounts of Aristotle’s views on the nature of the laughable. (shrink)

Using the example of recent attempts to engineer the concept of conspiracy theory, I argue that philosophers should be far more circumspect in their approach to conceptual engineering than we have been – in particular, that we should pay much closer attention to the history behind and context that surrounds our target concept in order to determine whether it is a site of what I have elsewhere called ‘conceptual domination’. If it is, we may well have good reason to avoid (...) engineering. In their recent ‘What is a Conspiracy Theory?’, M. Giulia Napolitano and Kevin Reuter argue that the disagreement between generalists and particularists in the literature on conspiracy theories is best characterized as a set of dueling conceptual engineering projects. While I agree with their turn to this metaphilosophical literature, I give a very different account of its applicability. Particularists, on my account, are better read as aiming to diagnose the ways in which many discussions of the concept of conspiracy theories are a form of conceptual domination, where this broader context should then prompt us to abandon or block any concept of conspiracy theory that treats its referents as inherently defective. Broader metaphilosophical lessons are drawn. (shrink)

By scholarly consensus, extant fragments from, and testimony about, Aristotle’s lost dialogue Eudemus provide strong evidence for thinking that Aristotle at some point defended the human soul’s unqualified immortality (either in whole or in part). I reject this consensus and develop an alternative, deflationary, speculative, but textually supported proposal to explain why Aristotle might have written a dialogue featuring arguments for the soul’s unqualified immortality. Instead of defending unqualified immortality as a doctrine, I argue, the Eudemus was most likely offering (...) a dramatically engaging propaedeutic to the sort of philosophical inquiry about the soul and its prospects that Aristotle pursues more scientifically in the De anima and Parva naturalia.

I claim that consciousness, just as thought or action, is only to be found at the personal level of explanation. Dennett's account is often taken to be at odds with this view, as it is seen as explicating consciousness in terms of sub-personal processes.

To see this, however, we need to understand better what content (...) ascription at the sub-personal level actually means. When we do we can see how Dennett presents both a philosophical account of consciousness and informed empirical speculation on the nature of its sub-personal underpinnings. Consciousness is a product of certain capacities that are intelligible only at the personal level, capacities that are neither present at the sub-personal level of brain mechanism nor present in 'sub-persons', e.g. some, if not all, non-human animals.

Matthew Arnold was born at Laleham-on-Thames on 24 December 1822 as the eldest son of Dr Thomas Arnold and his wife Mary. He was educated at Winchester College, his father's old school; Rugby, where his father was headmaster; and Oxford. In 1851 he was appointed Inspector of Schools, pursuing this taxing career to support his wife and family until his retirement in 1886. He published his first volume of verse, The Strayed Reveller, and other Poems, in 1849 followed by (...) Empedocles on Etna, and other Poems (1852) and five further collections which appeared, with a diminishing number of new poems in each, between 1853 and 1867, after which his creative gift appeared to dwindle still further and he published little poetry. His career as a writer of prose began to take over after his election to the Professorship of Poetry at Oxford in 1857. Stimulated by preparing his lectures, many of the earliest published in 1865 as Essays in Criticism (First Series), he turned increasingly to the vigorous and widely ranging polemical commentaries on culture, religion, and society which were to make him known at home and abroad as the foremost critic of his day. He died suddenly of heart failure on 15 April 1888 while awaiting at Liverpool the arrival of his married daughter from America. (shrink)

A response to Lee Basham's 'The Need for Accountable Witnesses: A Reply to Dentith'.

Surprisingly little has been written about hedged assertion. Linguists often focus on semantic or syntactic theorizing about, for example, grammatical evidentials or epistemic modals, but pay far less attention to what hedging does at the level of action. By contrast, philosophers have focused extensively on normative issues regarding what epistemic position is required for proper assertion, yet they have almost exclusively considered unqualified declaratives. This essay considers the linguistic and normative issues side-by-side. We aim to bring some order and clarity (...) to thinking about hedging, so as to illuminate aspects of interest to both linguists and philosophers. In particular, we consider three broad questions. 1) The structural question: when one hedges, what is the speaker’s commitment weakened from? 2) The functional question: what is the best way to understand how a hedge weakens? And 3) the taxonomic question: are hedged assertions genuine assertions, another speech act, or what? (shrink)

Ideal theory has been extensively contested on the grounds that it is ideology: namely, that it performs the distorting social role of reifying and enforcing unjust features of the status quo. Indeed, a growing number of philosophers adopt a nonideal methodology—which dispenses with ideal theory—because of this ideology critique. I argue, however, that such philosophers are confused about the ultimate dialectical upshot of this critique even if it succeeds. I do so by constructing a parallel—equally plausible—ideology critique of nonideal methodology; (...) specifically, I argue that capitalist and managerial social attitudes have commodified people’s conception of justice and induced suspicion of ideal theory, which is not construed as having direct practical value. Consequently, nonideal methodology performs the distorting role of reifying and enforcing the hegemonies of capitalism and managerialism. Ideal theory and nonideal methodology are, therefore, in symmetrically bad positions. (shrink)
