Abstract:This paper explores the contrast between mentalistic and behaviouristic interpretations of decision theory. The former regards credences and utilities as psychologically real, while the latter regards them as mere representations of an agent's preferences. Philosophers typically adopt the former interpretation, economists the latter. It is argued that the mentalistic interpretation is preferable if our aim is to use decision theory for descriptive purposes, but if our aim is normative then the behaviouristic interpretation cannot be dispensed with.

Many philosophers have claimed that Bayesianism can provide a simple justification for hypothetico-deductive inference, long regarded as a cornerstone of the scientific method. Following up a remark of van Fraassen, we analyze a problem for the putative Bayesian justification of H-D inference in the case where what we learn from observation is logically stronger than what our theory implies. Firstly, we demonstrate that in such cases the simple Bayesian justification does not necessarily apply. Secondly, we identify a set of sufficient conditions for the mismatch in logical strength to be justifiably ignored as a "harmless idealization''. Thirdly, we argue, based upon scientific examples, that the pattern of H-D inference of which there is a ready Bayesian justification is only rarely the pattern that one actually finds at work in science. Whatever the other virtues of Bayesianism, the idea that it yields a simple justification of a pervasive pattern of scientific inference appears to have been oversold.

This volume explores from multiple perspectives the subtle and interesting relationship between the theory of rational choice and Darwinian evolution. In rational choice theory, agents are assumed to make choices that maximize their utility; in evolution, natural selection 'chooses' between phenotypes according to the criterion of fitness maximization. So there is a parallel between utility in rational choice theory and fitness in Darwinian theory. This conceptual link between fitness and utility is mirrored by the interesting parallels between formal models of evolution and rational choice. The essays in this volume, by leading philosophers, economists, biologists and psychologists, explore the connection between evolution and rational choice in a number of different contexts, including choice under uncertainty, strategic decision making and pro-social behaviour. They will be of interest to students and researchers in philosophy of science, evolutionary biology, economics and psychology.

In a recent paper replying to the inductive sceptic, Samir Okasha says that the Humean argument for inductive scepticism depends on mistakenly construing inductive reasoning as based on a principle of the uniformity of nature. I dispute Okasha's argument that we are entitled to the background beliefs on which (he says) inductive reasoning depends. Furthermore, I argue that the sorts of theoretically impoverished contexts to which a uniformity-of-nature principle has traditionally been restricted are exactly the contexts relevant to the inductive sceptic's argument, and (pace Okasha) are not at all remote from actual scientific practice. I discuss several scientific examples involving such contexts

It seems hard to comprehend how, during mood experience, the ‘inner’ meets the ‘outer’. The objective of this paper is to show that a currently popular attempt at providing a neat solution to that problem fails. The attempt comes under the heading of representationalism, according to which the phenomenal aspects of mood are exhausted by its representational content. I examine three accounts of intentionality developed within the representationalist camp, and I show that they incur phenomenological and metaphysical costs.

Playwright, novelist, political theorist, literary critic and philosopher, Jean-Paul Sartre remains an iconic figure. This book examines his philosophical ideas and methods. It is an introductory guide for the student who wishes to understand Sartre's philosophical argumentation. It reconstructs in plain language key instances of Sartre's philosophical reasoning at work and shows how certain questions arise for Sartre and what philosophical tools he uses to address those questions. Each chapter considers a range of issues in the Sartrean corpus including his conception of phenomenology, the question of self-identity, the Sartrean view of conscious beings, his understanding of the self, his theory of value, human action as both the originator and the outcome of social processes, dialectical reason, and his conception of artistic activity. Hatzimoysis uncovers the philosophical argumentation, identifies Sartre's most important philosophical ideas and addresses the arguments in which those ideas are employed. Readers are able to get a real understanding of Sartre's approach to the activity of philosophising and how his method favours certain types of philosophical analysis

The Republic rarely speaks of piety; yet religious concerns inform more of its treatment of poetry than readers acknowledge. A pair of tripartite rankings in Book 10 has puzzled interpreters: first the triad Form-couch-painting, then the ostensibly equivalent triad of a flute’s or bridle’s user-maker-imitator. The tripartitions work better together if one recognizes the divinity at work behind Athena’s gifts the flute and bridle. This mythic reading reveals the imitator to stand, yet again, in opposition to the gods; but it also points toward an ambiguity about knowledge that Plato has forcibly excluded from his discussion.

Two great evaluative questions about The Birth of Tragedy ask how accurate the book is about Greece’s “tragic age,” and how nostalgic it is for that age. Wilamowitz raised the question of accuracy as soon as the book was published, and the issue has never gone away. As for nostalgia, even without accepting extreme versions of the charge, you can still worry that BT portrays Socrates as such a calamity—a monstrosity, and therefore a freakish birth, something that did not have to happen—as to invite the pious wish that he had never come along, and that the tragic age of Greece could have lived a little longer.Both evaluative questions are implicated in a perennial interpretive question: who is Nietzsche’s god ..

When the Phaedrus produces an account of eros that goes beyond earlier oversimplifying terms, it rests its analysis on a distinction between human and divine. The dialogue’s attempts to articulate this distinction repeatedly fail. In part they rest on the difference between right and left, but in ways that problematize that difference as well. In the end this difficulty in definition casts a shadow over the prospect of the effective reciprocation of love, because the loved one will not be able to tell the difference between a lover in pursuit crazed by divine eros and the lover who is crazed in the ordinary and destructive fashion.

Plato, often cited as a founding father of Western philosophy, set out ideas in the Republic regarding the nature of justice, order, and the character of the just individual, that endure into the modern day. The Routledge Guidebook to Plato’s Republic introduces the major themes in Plato’s great book and acts as a companion for reading the work, examining: The context of Plato’s work and the background to his writing Each separate part of the text in relation to its goals, meanings and impact The reception the book received when first seen by the world The relevance of Plato’s work to modern philosophy, its legacy and influence. With further reading included throughout, this text follows Plato’s original work closely, making it essential reading for all students of philosophy, and all those wishing to get to grips with this classic work

_Menexenus_ is one of the least studied among Plato's works, mostly because of the puzzling nature of the text, which has led many scholars either to reject the dialogue as spurious or to consider it as a mocking parody of Athenian funeral rhetoric. In this book, Pappas and Zelcer provide a persuasive alternative reading of the text, one that contributes in many ways to our understanding of Plato, and specifically to our understanding of his political thought. The book is organized into two parts. In the first part the authors offer a synopsis of the dialogue, address the setting and its background in terms of the Athenian funeral speech, and discuss the alternative readings of the dialogue, showing their weaknesses and strengths. In the second part, the authors offer their positive interpretation of the dialogue, taking particular care to explain and ground their interpretive criteria and method, which considers Plato's text not simply as a de-contextualized collection of philosophical arguments but offers a theoretically reading of the text that situates it firmly within its historical context. The book will become a reference point in the debate about the _Menexenus_ and Plato's political philosophy more generally and marks an important contribution to our understanding of ancient thought and classical Athenian society.

The existence of singularities alerts that one of the highest priorities of a centennial perspective on general relativity should be a careful re-thinking of the validity domain of Einstein’s field equations. We address the problem of constructing distinguishable extensions of the smooth spacetime manifold model, which can incorporate singularities, while retaining the form of the field equations. The sheaf-theoretic formulation of this problem is tantamount to extending the algebra sheaf of smooth functions to a distribution-like algebra sheaf in which the former may be embedded, satisfying the pertinent cohomological conditions required for the coordinatization of all of the tensorial physical quantities, such that the form of the field equations is preserved. We present in detail the construction of these distribution-like algebra sheaves in terms of residue classes of sequences of smooth functions modulo the information of singular loci encoded in suitable ideals. Finally, we consider the application of these distribution-like solution sheaves in geometrodynamics by modeling topologically-circular boundaries of singular loci in three-dimensional space in terms of topological links. It turns out that the Borromean link represents higher order wormhole solutions.
