Discusses the philosophy of science and the process of scientific discovery, and looks at ethical issues such as genetic engineering, prolonging life through technology, and the role of the physician.

Sir Peter Medawar wasn't only a Nobel prize-winning immunologist but also a writer about science and scientists. This entertaining selection presents the best of his writing, with a new foreword by Stephen Jay Gould, one of his greatest admirers.

The attitudes of scientists towards the philosophy of science is mixed and includes considerable indifference and some hostility. This may be due in part to unrealistic expectation and to misunderstanding. Philosophy is unlikely directly to improve scientific practices, but scientists may find the attempt to explain how science works and what it achieves of considerable interest nevertheless. The present state of the philosophy of science is illustrated by recent work on the ‘truth hypothesis’, according to which, science is generating increasingly (...) accurate representations of a mind-independent and largely unobservable world. According to Karl Popper, although truth is the aim of science, it is impossible to justify the truth hypothesis. According to Thomas Kuhn, the truth hypothesis is false, because scientists can only describe a world that is partially constituted by their own theories and hence not mind-independent. The failure of past scientific theories has been used to argue against the truth hypothesis; the success of the best current theories has been used to argue for it. Neither argument is sound.

Eminent scientists are well-placed to bring the novel works of others, even if not in their own areas of expertise, to general attention. In so doing, they may be able to extend original accounts or introduce new terminologies, but they are basically messengers, not innovators. In the 1940s an evolutionary theory of biological aging was explained by Peter Medawar, and informational concepts relating to DNA were explained by Erwin Schrödinger. Both explanations were eventually traced back to the Victorian (...) polymath Samuel Butler—one by Medawar’s research associate Alex Comfort, and the other, albeit indirectly, by Schrödinger himself. In his time Butler’s works were too erudite for general readers and too laden with populist jargon for contemporary experts to take seriously. However, today it appears counterfactually plausible that an early acceptance of his ideas would have greatly quickened the pace of research. (shrink)

When do two sentences say the same thing, that is, express the same content? We defend two-component (2C) semantics: the view that propositional contents comprise (at least) two irreducibly distinct constituents, (1) truth-conditions, and (2) subject-matter. We contrast 2C with one-component (1C) semantics, focusing on the view that subject-matter is reducible to truth- conditions. We identify exponents of this view and argue in favor of 2C. An appendix proposes a general formal template for propositional 2C semantics.

Berkeley’s likeness principle is the claim that “an idea can be like nothing but an idea”. The likeness principle is intended to undermine representationalism: the view (that Berkeley attributes to thinkers like Descartes and Locke) that all human knowledge is mediated by ideas in the mind which represent material objects. Yet, Berkeley appears to leave the likeness principle unargued for. This has led to several attempts to explain why Berkeley accepts it. In contrast to ‘metaphysical’ and ‘epistemological’ interpretations available in (...) the literature, in this paper I defend a ‘conceptual’ interpretation. I argue that Berkeley accepts the likeness principle on the basis of (i) his commitment to the transparency of ideas, and (ii) his account of resemblance which he sets out in his works on vision. Thus, I provide an explanation for Berkeley’s reasons for accepting the likeness principle which, appropriately, focuses on his views concerning ideas and likeness. (shrink)

Originally published in 1969. This book explains what is wrong with the traditional methodology of "inductive" reasoning and shows that the alternative scheme of reasoning associated with Whewell, Pierce and Popper can give the scientist a useful insight into the way he thinks.

Margaret Macdonald was at the institutional heart of analytic philosophy in Britain in the mid-twentieth century. Yet, her views on the nature of philosophical theories diverge quite considerably from those of many of her contemporaries. In this paper, I focus on her 1953 article ‘Linguistic Philosophy and Perception’, a provocative paper in which Macdonald argues that the value of philosophical theories is more akin to that of poetry or art than science or mathematics. I do so for two reasons. First, (...) because it reveals just how far Macdonald’s meta- philosophical views diverged from those of many of her contemporaries. Second, because the discussion in LPP pre-empts recent literature on the nature of philosophical inquiry and the efficacy of philosophical arguments. Indeed, Macdonald’s paper is just as likely to provoke discussion today as it was in the 1950s. (shrink)

Since its original publication in 1975, this groundbreaking work has awakened millions of people to the existence of "speciesism"—our systematic disregard of nonhuman animals—inspiring a worldwide movement to transform our attitudes to animals and eliminate the cruelty we inflict on them. In Animal Liberation, author Peter Singer exposes the chilling realities of today’s "factory farms" and product-testing procedures—destroying the spurious justifications behind them, and offering alternatives to what has become a profound environmental and social as well as moral issue. (...) An important and persuasive appeal to conscience, fairness, decency, and justice, it is essential reading for the supporter and the skeptic alike. (shrink)

It is argued that causal understanding originates in experiences of acting on objects. Such experiences have consistent features that can be used as clues to causal identification and judgment. These are singular clues, meaning that they can be detected in single instances. A catalog of 14 singular clues is proposed. The clues function as heuristics for generating causal judgments under uncertainty and are a pervasive source of bias in causal judgment. More sophisticated clues such as mechanism clues and repeated interventions (...) are derived from the 14. Research on the use of empirical information and conditional probabilities to identify causes has used scenarios in which several of the clues are present, and the use of empirical association information for causal judgment depends on the presence of singular clues. It is the singular clues and their origin that are basic to causal understanding, not multiple instance clues such as empirical association, contingency, and conditional probabilities. (shrink)

In this important new book in the IPPP series, a group of leading thinkers in psychiatry, psychology, and philosophy offer alternative perspectives that address both the scientific and clinical aspects of psychiatric validation, emphasizing throughout their philosophical and historical considerations.

Prospect Theory: For Risk and Ambiguity, provides a comprehensive and accessible textbook treatment of the way decisions are made both when we have the statistical probabilities associated with uncertain future events and when we lack them. The book presents models, primarily prospect theory, that are both tractable and psychologically realistic. A method of presentation is chosen that makes the empirical meaning of each theoretical model completely transparent. Prospect theory has many applications in a wide variety of disciplines. The material in (...) the book has been carefully organized to allow readers to select pathways through the book relevant to their own interests. With numerous exercises and worked examples, the book is ideally suited to the needs of students taking courses in decision theory in economics, mathematics, finance, psychology, management science, health, computer science, Bayesian statistics, and engineering.

William Molyneux was born in Dublin, studied in Trinity College Dublin, and was a founding member of the Dublin Philosophical Society (DPS), Ireland’s counterpart to the Royal Society in London. He was a central figure in the Irish intellectual milieu during the Early Modern period and – along with George Berkeley and Edmund Burke – is one of the best-known thinkers to have come out of that context and out of Irish thought more generally. In 1688, when Molyneux wrote the (...) letter to Locke in which he posed the now famous question about a man born blind made to see, he was an active member of the DPS and was on familiar terms with several other key figures in Irish philosophy at the time. For the most part, Irish thinkers in the seventeenth and eighteenth centuries answered “no” to Molyneux’s question of whether a blind man made to see could distinguish, by sight alone, between a cube and a sphere.

This book examines the complex and varied ways in which fictions relate to the real world, and offers a precise account of how imaginative works of literature can use fictional content to explore matters of universal human interest. While rejecting the traditional view that literature is important for the truths that it imparts, the authors also reject attempts to cut literature off altogether from real human concerns. Their detailed account of fictionality, mimesis, and cognitive value, founded on the methods of (...) analytical philosophy, restores to literature its distinctive status among cultural practices. The authors also explore metaphysical and skeptical views, prevalent in modern thought, according to which the world itself is a kind of fiction, and truth no more than a social construct. They identify different conceptions of fiction in science, logic, epistemology, and make-believe, and thereby challenge the idea that discourse per se is fictional and that different modes of discourse are at root indistinguishable. They offer rigorous analyses of the roles of narrative, imagination, metaphor, and "making" in human thought processes. Both in their methods and in their conclusions, Lamarque and Olsen aim to restore rigor and clarity to debates about the values of literature, and to provide new, philosophically sound foundations for a genuine change of direction in literary theorizing.

P.F. Strawson's essay traces some formal characteristics of logic and grammar to their roots in general features of thought and experience.

This paper provides a philosophical evaluation of the concept of handedness prevalent but largely unspoken in the scientific literature. This literature defines handedness as the preference or ability to use one hand rather than the other across a range of common activities. Using the philosophical discipline of phenomenology, I articulate and critique this conceptualization of handedness. Phenomenology shows defining a concept of handedness by focusing on hand use leads to a right hand biased concept. I argue further that a phenomenological (...) model based in spatial orientation rather than hand use provides a more inclusive concept of handedness. (shrink)

In my contribution to this Concise Collection on Margaret Cavendish, I focus on teaching Cavendish’s work in the context of philosophy (and, more specifically, Early Modern Philosophy). I have three aims. First, to explain why teaching women from philosophy’s history is crucially important to the discipline. Second, to outline my own reflections on teaching Cavendish’s philosophy. Third, to defend a specific claim about the benefits of teaching Cavendish to philosophy students; namely, that introducing biographical detail alongside philosophical ideas enriches the (...) learning experience.

Originally published in 1957, The Uniqueness of the Individual is a collection of 9 essays published from the ten years preceding publication. The essays deal with some of the central problems of biology. These are among the questions put and answered from the standpoint of modern experimental biology. What is ageing and how is it measured? What theories have been held to account for it, and with what success? Did ageing evolve, and if so how? Is Lamarckism and adequate explanation (...) of evolutionary process? Does evolution sometimes go wrong? Do human beings evolve in a way peculiar to themselves? Other essays touch upon the problems of scientific method and of growth and transformation. This book will be of interest to natural historians, evolutionists and anthropologists. (shrink)

In this article I intend to justify six theses: (1) Temporal becoming is founded in an intuition-form of self-intuition, whereas physical space-time is independent of any form of intuition; (2) communicable thoughts are, as Kant says, products of self-consciousness; (3) both roots of idealism are connected by the tensed form of predication; (4) the thinking subject is, as Kant says, an appearance for itself; (5) the subject has, in virtue of this nature, the capacity of mental causality; and (6) mental (...) causality is a sufficient basis for a Kantian “causality from freedom”.

The problem with authenticity—the idea of being “true to one’s self”—is that its somewhat checkered reputation garners a complete range of favorable and unfavorable reactions. In educational settings, authenticity is lauded as one of the top two traits students desire in their teachers. Yet, authenticity is criticized for its tendency towards narcissism and self-entitlement. So, is authenticity a good or a bad thing? The purpose of this article is to develop an intimate understanding of authenticity by investigating its current interpretation (...) and criticisms, its struggle with narcissism and relation to freedom. Examining authenticity as multilayered self-exploration reveals a composite of understanding, care, and acceptance. While a side current of acceptable tension shifts our understanding of authenticity from the security of self-determination to the messy interplay involved in being “true to one’s self” and being “in-the-world”.

In der genannten Epoche werden Grundentscheidungen gefällt, welche die Fundamentalfrage der Philosophie, die Seinsfrage, in die Krisis führen, in den Nihilismus unter ontologischem, metaphysischem, epistemologischem, axiologischem Aspekt. Den Extrempositionen der Systemdenker Hegel, Schopenhauer und Schelling erwachsen in den Hegelkritikern Feuerbach, Br. Bauer, Marx und Stirner Kontrapositionen, die das Wahrheitsproblem der Beliebigkeit unterstellen. Kierkegaard klagt unter existentiellem Aspekt das Problem der Wahrheit ein. Nietzsche überholt durch Abschaffung der Wahrheit alle Positionen,was seinen Standort in der europäischen Denkgeschichte ausmacht und als Ergebnis der (...) problemgeschichtlichen Analysen zu charakterisieren ist. Die Rückgewinnung des Vernunfthorizontes setzen erst die Problemdenker N. Hartmann und M. Heidegger ins Werk durch kritische Erneuerung der Seinsfrage. (shrink)
