From the 1910s through the 1930s, the American naturalist and photographer Arthur C. Pillsbury made time-lapse and microscopic films documenting what he, in common parlance, called the “miracles of plant life”. While these films are now mostly lost, they were part of Pillsbury’s prolific work as a conservationist and traveling film lecturer who used his cameras everywhere from Yosemite National Park to Samoa to promote both public understanding of plants and a desire to protect the natural world. Guiding this work (...) was Pillsbury’s belief that the nonhuman optics of the film camera, which revealed the animacy of plants, could also incite viewers to sympathize with them. In the context of the early American conservation movement, that sympathy stemmed in complicated ways from longstanding transcendental and pastoral ideas of nature that were entangled with imperialist visions of controlling nature. With an eye to that context, I show that Pillsbury’s filmmaking was not simply about using motion picture technologies to shape attitudes toward plants and nature more broadly; it was also about using nature to think through the techno-scientific possibilities of the cinema in the early part of the twentieth century.

In a well-known paper, Timothy Williamson claimed to prove with a coin-flipping example that infinitesimal-valued probabilities cannot save the principle of Regularity, because on pain of inconsistency the event ‘all tosses land heads’ must be assigned probability 0, whether the probability function is hyperreal-valued or not. A premise of Williamson’s argument is that two infinitary events in that example must be assigned the same probability because they are isomorphic. It was argued by Howson that the claim of isomorphism (...) fails, but a more radical objection to Williamson’s argument is that it had been, in effect, refuted long before it was published.

Timothy Williamson has claimed to prove that regularity must fail even in a nonstandard setting, with a counterexample based on tossing a fair coin infinitely many times. I argue that Williamson’s argument is mistaken, and that a corrected version shows that it is not regularity which fails in the non-standard setting but a fundamental property of shifts in Bernoulli processes.

Philosophers cannot agree on whether the rule of Countable Additivity should be an axiom of probability. Edwin T. Jaynes attacks the problem in a way which is original to him and passed over in the current debate about the principle: he says the debate only arises because of an erroneous use of mathematical infinity. I argue that this solution fails, but I construct a different argument which, I argue, salvages the spirit of the more general point Jaynes makes. I argue (...) that in Jaynes’s objective Bayesianism we might have good reasons to adopt Countable Additivity, and some of the major problems this adoption is known to entail need not worry us. In particular, I propose to adopt this new angle on Countable Additivity in Jon Williamson’s version of objective Bayesianism. (shrink)

Timothy Williamson claimed to prove with a coin-tossing example that hyperreal probabilities cannot save the principle of regularity. A premise of his argument is that two specified infinitary events must be assigned the same probability because, he claims, they are isomorphic. But as has been pointed out, they are not isomorphic. A way of framing Williamson’s argument that does not make it depend on the isomorphism claim is in terms of shifts in Bernoulli processes, the usual mathematical model (...) of sequential coin tossing. But even so framed, the argument still fails. (shrink)

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

Vagueness provides the first comprehensive examination of a topic of increasing importance in metaphysics and the philosophy of logic and language. Timothy Williamson traces the history of this philosophical problem from discussions of the heap paradox in classical Greece to modern formal approaches such as fuzzy logic. He illustrates the problems with views which have taken the position that standard logic and formal semantics do not apply to vague language, and defends the controversial realistic view that vagueness is a (...) kind of ignorance--that there really is a grain of sand whose removal turns a heap into a non-heap, but we cannot know which one it is.

In the mid-eighteenth century David Hume argued that successful prediction tells us nothing about the truth of the predicting theory. But physical theory routinely predicts the values of observable magnitudes within very small ranges of error. The chance of this sort of predictive success without a true theory suggests that Hume's argument is flawed. However, Colin Howson argues that there is no flaw and examines the implications of this disturbing conclusion; he also offers a solution to one of the (...) central problems of Western philosophy, the problem of induction.

When I take off my glasses, the world looks blurred. When I put them back on, it looks sharpedged. I do not think that the world really was blurred; I know that what changed was my relation to the distant physical objects ahead, not those objects themselves. I am more inclined to believe that the world really is and was sharp-edged. Is that belief any more reasonable than the belief that the world really is and was blurred? I see more (...) accurately with my glasses on than off, so visual appearances when they are on have some cognitive priority over visual appearances when they are off. If I must choose which kind of visual appearance to take at face value, I will choose the sharp-edged look. But what should I think when I see a mist, which looks very blurred however well I am seeing? Indeed, why choose to take any of the looks at face value? Why not regard all the choices as illegitimate projections of ways of seeing the world onto the world itself? (shrink)

The second volume in the _Blackwell Brown Lectures in Philosophy_, this volume offers an original and provocative take on the nature and methodology of philosophy. Based on public lectures at Brown University, given by the pre-eminent philosopher, Timothy Williamson Rejects the ideology of the 'linguistic turn', the most distinctive trend of 20th century philosophy Explains the method of philosophy as a development from non-philosophical ways of thinking Suggests new ways of understanding what contemporary and past philosophers are doing.

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

Aimed at philsophy graduates this book investigates mental content in a systematic way and advances a number of claims about how mental content states are related to the body and the world. Internalism is the thesis that they are; externalism is the theory that they are not.

The paper clarifies and defends the orthodox view that counterfactual conditionals with impossible antecedents are vacuously true against recent criticisms. It argues that apparent counterexamples to orthodoxy result from uncritical reliance on a fallible heuristic used in the processing of conditionals. A comparison is developed between such counterpossibles and vacuously true universal generalizations.

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)

This volume provides a guide to the discussion among biologists and philosophersabout the role of concepts such as function and design in an evolutionary understanding oflife.

The epistemic position of an agent often depends on their position in a larger network of other agents who provide them with information. In general, agents are better off if they have diverse and independent sources. Sullivan et al. [19] developed a method for quantitatively characterizing the epistemic position of individuals in a network that takes into account both diversity and independence; and presented a proof-of-concept, closed-source implementation on a small graph derived from Twitter data [19]. This paper reports on (...) an open-source reimplementation of their algorithm in Python, optimized to be usable on much larger networks. In addition to the algorithm and package, we also show the ability to scale up our package to large synthetic social network graph profiling, and finally demonstrate its utility in analyzing real-world empirical evidence of ‘echo chambers’ on online social media, as well as evidence of interdisciplinary diversity in an academic communications network.

In recent years there has been a resurgence of interest in the work of Emmanuel Levinas, widely recognized as one of the most important yet difficult philosophers of the 20th century. In this much-needed introduction, Davis unpacks the concepts at the centre of Levinas's thought - alterity, the Other, the Face, infinity - concepts which have previously presented readers with major problems of interpretation. Davis traces the development of Levinas's thought over six decades, describing the context in which he worked, (...) and the impact of his writings. He argues that Levinas's work remains tied to the ontological tradition with which he wants to break, and demonstrates how his later writing tries to overcome this dependency by its increasingly disruptive, sometimes opaque, textual practice. He discusses Levinas's theological writings and his relationship to Judaism, as well as the reception of his work by contemporary thinkers, arguing that the influence of his work has led to a growing interest in ethical issues among poststructuralist and postmodernist thinkers in recent years. Comprehensive and clearly written, this book will be essential reading for students and researchers in continental philosophy, French studies, literary theory and theology. (shrink)

This chapter presents an overview of the major interpretations of probability followed by an outline of the objective Bayesian interpretation and a discussion of the key challenges it faces. I discuss the ramifications of interpretations of probability and objective Bayesianism for the philosophy of mathematics in general.

Pragmatism is America's best-known native philosophy. It espouses a practical set of beliefs and principles that focus on the improvement of our lives. Yet the split between classical and contemporary pragmatists has divided the tradition against itself. Classical pragmatists, such as John Dewey and William James, believed we should heed the lessons of experience. Neopragmatists, including Richard Rorty, Hilary Putnam, and Jürgen Habermas, argue instead from the perspective of a linguistic turn, which makes little use of the idea of experience. (...) Can these two camps be reconciled in a way that revitalizes a critical tradition? -/- Colin Koopman proposes a recovery of pragmatism by way of "transitionalist" themes of temporality and historicity which flourish in the work of the early pragmatists and continue in contemporary neopragmatist thought. "Life is in the transitions," James once wrote, and, in following this assertion, Koopman reveals the continuities uniting both phases of pragmatism. Koopman's framework also draws from other contemporary theorists, including Michel Foucault, Pierre Bourdieu, Bernard Williams, and Stanley Cavell. By reflecting these voices through the prism of transitionalism, a new understanding of knowledge, ethics, politics, and critique takes root. Koopman concludes with a call for integrating Dewey and Foucault into a model of inquiry he calls genealogical pragmatism, a mutually informative critique that further joins the analytic and continental schools.

In this study of the nature of philosophy, Colin McGinn shows us how philosophy can maintain its connection to the past while looking forward to a bright future.

McGinn's latest brings together moral philosophy and literary analysis in a way that illuminates both. Setting out to enrich the domain of moral reflection by showing the value of literary texts as sources of moral illumination, McGinn starts by setting out an uncompromisingly realist ethical theory, arguing that morality is an area of objective truth and genuine knowledge. He goes on to address such subjects as the nature of goodness, evil character, and the meaning of monstrosity in the context of (...) an aesthetic theory of virtue, which maintains that goodness of character is the same thing as beauty of soul. Looking at such literary works as Billy Budd, Lolita, The Picture of Dorian Gray, and Frankenstein, as well as examples from film and painting, Ethics, Evil, and Fiction is an original and compelling book by a leading philosopher who is also a critic and novelist.

Imagine a philosophy conference in Presocratic Greece. The hot question is: what are things made of? Followers of Thales say that everything is made of water, followers of Anaximenes that everything is made of air, and followers of Heraclitus that everything is made of fire. Nobody is quite clear what these claims mean, and some question whether the founders of the respective schools ever made them. But amongst the groupies there is a buzz about all the recent exciting progress. The (...) mockers and doubters make plenty of noise too. They point out that no resolution of the dispute between the schools is in sight. They diagnose Thales, Anaximenes and Heraclitus as suffering from a tendency to overgeneralize. We can intelligibly ask what bread is made of, or what houses are made of, but to ask what things in general are made of is senseless, some suggest, because the question is posed without any conception of how to verify an answer; language has gone on holiday. Paleo-pragmatists invite everyone to relax, forget their futile pseudo-inquiries and do something useful instead. (shrink)

The long eighteenth century is a crucial period in the history of ethics, when our moral relations to God, ourselves and others were minutely examined and our duties, rights and virtues systematically and powerfully presented. Colin Heydt charts the history of practical morality - what we ought to do and to be - from the 1670s, when practical ethics arising from Protestant natural law gained an institutional foothold in England, to early British responses to the French Revolution around 1790. (...) He examines the conventional philosophical positions concerning the content of morality, and utilizes those conventions to reinterpret the work of key figures including Locke, Hume, and Smith. Situating these positions in their thematic and historical contexts, he shows how studying them challenges our assumptions about the originality, intended audience, and aims of philosophical argument during this period. His rich and readable book will appeal to a range of scholars and students. (shrink)

Schopenhauer repeatedly claims that suicide is both foolish and futile. But while many commentators have expressed sympathy for his charge of foolishness, most regard his charge of futility as indefensible even within his own system. In this paper, I offer a defense of Schopenhauer’s futility charge, based on metaphysical and psychological considerations. On the metaphysical front, Schopenhauer’s view implies that psychological connections extend beyond death. Drawing on Parfit’s discussion of personal identity, I argue that those connections have personal significance, such (...) that suicide does not allow one, as Hamlet hopes, simply “not to be.” On the psychological front, I argue that a distinction between agents’ intentions and underlying desires makes room for Schopenhauer to claim that paradigmatic suicidal agents ultimately desire the opposite of what suicide accomplishes. I conclude by showing how the resulting account of futility can buttress the charge of foolishness as well. My interpretation still leaves Schopenhauer vulnerable to certain objections, but shows that his account is significantly more defensible than previous commentators have realized. (shrink)

This chapter begins with an overview of John Rawls's four‐stage sequence account of how to apply justice as fairness to institutions. It focuses on the facets of institutional design: (i) How should basic democratic institutions and processes be structured so as to realize the fair value of the basic political liberties? (ii) What kinds of educational and health institutions are needed to secure fair equality of opportunity? (iii) How do principles of justice apply to the family? (iv) What implications does (...) the difference principle have for the structure of a market economy? Rawls's extension of the original position via the four‐stage sequence proceeds against the background of three kinds of pluralism. According to Rawls, occupational choice means that there is a diversity of positions open to all citizens, and no one is forced to hold or pursue specific kinds of employment. (shrink)

Metaphysical modalities are definable from counterfactual conditionals, and the epistemology of the former is a special case of the epistemology of the latter. In particular, the role of conceivability and inconceivability in assessing claims of possibility and impossibility can be explained as a special case of the pervasive role of the imagination in assessing counterfactual conditionals, an account of which is sketched. Thus scepticism about metaphysical modality entails a more far-reaching scepticism about counterfactuals. The account is used to question the (...) significance of the distinction between a priori and a posteriori knowledge. (shrink)

Many weaknesses of game theory are cured by new models that embody simple cognitive principles, while maintaining the formalism and generality that makes game theory useful. Social preference models can generate team reasoning by combining reciprocation and correlated equilibrium. Models of limited iterated thinking explain data better than equilibrium models do; and they self-repair problems of implausibility and multiplicity of equilibria.

Plato’s Theaetetus, Sophist, and Statesman exhibit several related dialectical methods relevant to Platonic education: maieutic in Theaetetus, bifurcatory division in Sophist and Statesman, and non-bifurcatory division in Statesman, related to the ‘god-given’ method in Philebus. I consider the nature of each method through the letter or element paradigm, used to reflect on each method. At issue are the element’s appearances in given contexts, its fitness for communing with other elements like it in kind, and its own nature defined through its (...) relations to others. These represent stages of inquiry for the Platonic student inquiring into the sources of knowledge. (shrink)

Henry More argues that materialism cannot account for cases where a single subject or perceiver has multiple perceptions simultaneously. Since we clearly do have multiple perceptions at the same time--for example, when we see, hear, and smell simultaneously--More concludes that we are not wholly material. In response to More's argument, Margaret Cavendish adopts a two-fold strategy. First, she argues that there is no general obstacle to mental unification in her version of materialism. Second, Cavendish appeals to the mind or rational (...) matter--terms she often uses interchangeably—to explain the integration of sensory input from multiple senses. When the mind integrates perceptions across modalities, the different parts of rational matter share their knowledge so that they all come to perceive alike. When rational parts successfully communicate their knowledge, each part knows what all the others know. They pool their knowledge; they perceive alike. Thus, when someone hears, sees, and tastes, each part of her mind hears, sees, and tastes alike, in parallel and in unison. The Cavendishian mind, in short, approximates simplicity by achieving uniformity or homogeneity of perceptions across its parts. (shrink)

According to Jago (2014a), logical omniscience is really part of a deeper paradox. Jago develops an epistemic logic with principles of indeterminate closure to solve this paradox, but his official semantics is difficult to navigate, it is motivated in part by substantive metaphysics, and the logic is not axiomatized. In this paper, I simplify this epistemic logic by adapting the hyperintensional semantic framework of Sedlár (2021). My first goal is metaphysical neutrality. The solution to the epistemic paradox should not require (...) appeal to a metaphysics of truth-makers, situations, or impossible worlds, by contrast with Jago’s official semantics. My second goal is to elaborate on the proof theory. I show how to axiomatize a family of logics with principles of indeterminate epistemic closure. (shrink)

Consider the distinctive qualitative property grass visually appears to have when it visually appears to be green. This property is an example of what I call sensuous color. Whereas early modern mechanists typically argue that bodies are not sensuously colored, Margaret Cavendish (1623–73) disagrees. In cases of veridical perception, she holds that grass is green in precisely the way it visually appears to be. In defense of her realist approach to sensuous colors, Cavendish argues that (i) it is impossible to (...) conceive of colorless bodies, (ii) the very possibility of color experience requires that bodies are sensuously colored, and (iii) the attribution of sensuous colors to bodies provides the best explanation of color constancy. Although some passages might suggest that Cavendish endorses a reductive account of sensuous color, according to which sensuous color reduces to a body's microscopic surface texture (or some other mechanistically respectable property), I argue that she accepts a nonreductive account, on which sensuous color is not thus reducible.

Religion and the Rebel, Colin Wilson's second volume from his internationally acclaimed Outsider Cycle, is a casebook about and for rebels. With inspirational wisdom and engaging clarity, Wilson shows us that the purpose of religion, of our personal relationship with the sacred and the all-pervading mystery of existence, is to expand our consciousness and intensify our sense of life. Wilson heroically claims that the power to create meaning resides in our mental and spiritual discipline. Examining the lives and works (...) of Nietzsche, Kierkegaard, Rilke, Shaw, Pascal, Swedenborg, Rimbaud and Scott Fitzgerald, among others, Wilson explores the main existential questions and shows how these remarkable writers, scientists, philosophers and poets faced their need for transcendence. Like many of us, they were driven by a need to become more than men. Religion and the Rebel is an outstanding and enjoyable book that combines philosophical analysis, historical interest, and religious insight. (shrink)

This chapter aims to attempt no more than to make some informal and unsystematic remarks on the transformation of analytic philosophy. It deals with a few sketchy remarks on the historiography of recent analytic philosophy. Writing in 1981, David Lewis described “a reasonable goal for a philosopher” as bringing one’s opinions into stable equilibrium. A natural comparison is between Lewis’s Quinean or at least post‐Quinean methodology and the methodology of Peter Strawson, Quine’s leading opponent from the tradition of ordinary language (...) philosophy. Analytic epistemology provides a good case study of the philosophical application of Gricean pragmatics outside the philosophy of language. On Michael Dummett picture of the history of philosophy, Descartes had made epistemology first philosophy, the engine for the rest of philosophy, and then Frege had replaced epistemology by the philosophy of language as first philosophy. The chapter suggests that philosophy sometimes already uses an abductive methodology and ought to use it more in the future. (shrink)

The heart of this book is the reciprocal relationship between philosophical theories of mind and empirical studies of animal cognition.

Many, including Marx, Rawls, and the contemporary 'Black Lives Matter' movement, embrace the ambition to secure terms of co-existence in which the worth of people's lives becomes a lived reality rather than an empty boast. This book asks whether, as some believe, the philosophical idea of human dignity can help achieve that ambition. Offering a new fourfold typology of dignity concepts, Colin Bird argues that human dignity can perform this role only if certain traditional ways of conceiving it are (...) abandoned. Accordingly, Bird rejects the idea that human dignity refers to the inherent worth or status of individuals, and instead reinterprets it as a social relation, constituted by affects of respect and the modes of mutual attention which they generate. What emerges is a new vision of human dignity as a vital political value, and an arresting vindication of its role as an agent of critical reflection on politics. (shrink)
