Publisher’s Note: This volume consists of fourteen chapters that focus on a trio of interrelated themes. First: what are the powers and limits of appeals to intuition in supporting or refuting various sorts of claims? Second: what are the cognitive consequences of engaging with content that is represented as imaginary or otherwise unreal? Third: what are the implications of these issues for the methodology of philosophy more generally? These themes are explored in a variety of cases, including thought experiments in science and philosophy, early childhood pretense, self?deception, cognitive and emotional engagement with fiction, mental and motor imagery, automatic and habitual behavior, and social categorization.
Formal Languages in Logic: A Philosophical and Cognitive Analysis
Formal languages are widely regarded as being above all mathematical objects and as producing a greater level of precision and technical complexity in logical investigations because of this. Yet defining formal languages exclusively in this way offers only a partial and limited explanation of the impact which their use (and the uses of formalisms more generally elsewhere) actually has. In this book, Catarina Dutilh Novaes adopts a much wider conception of formal languages so as to investigate more broadly what exactly is going on when theorists put these tools to use. She looks at the history and philosophy of formal languages and focuses on the cognitive impact of formal languages on human reasoning, drawing on their historical development, psychology, cognitive science and philosophy. Her wide-ranging study will be valuable for both students and researchers in philosophy, logic, psychology and cognitive and computer science.
The Ontology of Mind: Events, Processes, and States
Publisher’s Note: This book puts forward a radical critique of the foundations of contemporary philosophy of mind, arguing that it relies too heavily on insecure assumptions about the nature of some of the sorts of mental entities it postulates: the nature of events, processes, and states. The book offers an investigation of these three categories, clarifying the distinction between them, and argues specifically that the assumption that states can be treated as particular, event-like entities has been a huge and serious mistake. The book argues that the category of token state should be rejected, and develops an alternative way of understanding those varieties of causal explanation which have sometimes been thought to require an ontology of token states for their elucidation. The book contends that many current theories of mind are rendered unintelligible once it is seen how these explanations really work. A number of prominent features of contemporary philosophy of mind token identity theories, the functionalists conception of causal role, a common form of argument for eliminative materialism, and the structure of the debate about the efficacy of mental content are impugned by the book’s arguments. The book concludes that the modern mind-body problem needs to be substantially rethought.
The Justification of Deduction
Abstract: It is often taken for granted by writers who propose – and, for that matter, by writers who oppose – ‘justifications’ of inductions, that deduction either does not need, or can readily be provided with, justification. The purpose of this paper is to argue that, contrary to this common opinion, problems analogous to those which, notoriously, arise in the attempt to justify induction, also arise in the attempt to justify deduction.
Philosophy of Logics
Publisher’s Note: The first systematic exposition of all the central topics in the philosophy of logic, Susan Haack’s book has established an international reputation (translated into five languages) for its accessibility, clarity, conciseness, orderliness, and range as well as for its thorough scholarship and careful analyses. Haack discusses the scope and purpose of logic, validity, truth-functions, quantification and ontology, names, descriptions, truth, truth-bearers, the set-theoretical and semantic paradoxes, and modality. She also explores the motivations for a whole range of nonclassical systems of logic, including many-valued logics, fuzzy logic, modal and tense logics, and relevance logics.
The Degree of Epistemic Justification and the Conjunction Fallacy
Abstract: This paper describes a formal measure of epistemic justification motivated by the dual goal of cognition, which is to increase true beliefs and reduce false beliefs. From this perspective the degree of epistemic justification should not be the conditional probability of the proposition given the evidence, as it is commonly thought. It should be determined instead by the combination of the conditional probability and the prior probability. This is also true of the degree of incremental confirmation, and I argue that any measure of epistemic justification is also a measure of incremental confirmation. However, the degree of epistemic justification must meet an additional condition, and all known measures of incremental confirmation fail to meet it. I describe this additional condition as well as a measure that meets it. The paper then applies the measure to the conjunction fallacy and proposes an explanation of the fallacy.
Critical notice: Telling and trusting: Reductionism and anti-reductionism in the epistemology of testimony
Abstract: In this review I focus on the arguments advanced by Coady in the main task to which he addresses himself in Testimony: arguing the case against the reductive position, and in favour of a non-reductive conception of testimonial knowledge. I introduce some distinctions which I believe enable the subject to taken further.
Against Gullibility
Summary: This paper refutes the PR thesis according to which the hearer has such a special presumptive right to trust the speaker’s assertion. The refutation consists of 1) arguing against that it is not possible for a hearer to obtain independent confirmation that a given speaker is trustworthy – that what she says will be true; 2) a full rejection to various positive arguments for a PR which may be made.
Chance, Possibility and explanation
Summary: In this paper the author argues against the common and influential view that non-trivial chances arise only when the fundamental laws are indeterministic. The problem with this view, she claims, is not that it conflicts with some antecedently plausible metaphysics of chance or that it fails to capture our everyday use of ‘chance’ and related terms, but rather that it is unstable. Any reason for adopting the position that non-trivial chances arise only when the fundamental laws are indeterministic is also a reason for adopting a much stronger, and far less attractive, position. Emery suggests an alternative account, according to which chances are probabilities that play a certain explanatory role: they are probabilities that explain associated frequencies.
Belief Contexts and Epistemic possibility
Abstract: Although epistemic possibility figures in several debates, those debates have had relatively little contact with one another. G. E. Moore focused squarely upon analyzing epistemic uses of the phrase, ‘It’s possible that p’, and in doing so he made two fundamental assumptions. First, he assumed that epistemic possibility statements always express the epistemic position of a community, as opposed to that of an individual speaker. Second, he assumed that all epistemic uses of ‘It’s possible that p’ are analyzable in terms of knowledge, not belief. A number of later theorists, including Keith DeRose, provide alternative accounts of epistemic possibility, while retaining Moore’s two assumptions. Neither assumption has been explicitly challenged, but Jaakko Hintikka’s analysis provides a basis for doing so. Drawing upon Hintikka’s analysis, I argue that some epistemic possibility statements express only the speaker’s individual epistemic state, and that contra DeRose, they are not degenerate community statements but a class in their own right. I further argue that some linguistic contexts are belief- rather than knowledge-based, and in such contexts, what is possible for a speaker depends not upon what she knows, but upon what she believes.
