A dissertation in the tradition of logical positivism includes a discussion of the functions and methods of philosophy and a critique of ethics and theology.

This book traces the development of formal logic from its origins in ancient Greece to the present day. The authors first discuss the work of logicians from Aristotle to Frege, showing how they were influenced by the philosophical or mathematical ideas of their time. They then examine developments in the present century.

Robert Hanna presents a fresh view of the Kantian and analytic traditions that have dominated continental European and Anglo-American philosophy over the last two centuries, and of the connections between them. But this is not just a study in the history of philosophy, for out of this emerges Hanna's original approach to two much-contested theories that remain at the heart of contemporary philosophy. Hanna puts forward a new 'cognitive-semantic' interpretation of transcendental idealism, and a vigorous defense of Kant's theory of (...) analytic and synthetic necessary truth, making this compelling reading for all who are interested in these fundamental philosophical issues.

Early paper on the nature of the a priori in Kant and its relationship to modality.

The fundamental task of philosophy since the seventeenth century has been to determine whether the essential principles of both knowledge and action can be discovered by human beings unaided by an external agency. No one philosopher contributed more to this enterprise than Kant, whose Critique of Pure Reason shook the very foundations of the intellectual world. Kant argued that the basic principles of the natural sciences are imposed on reality by human sensibility and understanding, and thus that human beings are (...) also free to impose their own free and rational agency on the world. This volume is the only systematic and comprehensive account of the full range of Kant 's writings available, and the first major overview of his work to be published in more than a dozen years. An internationally recognized team of Kant scholars explore Kant 's conceptual revolution in epistemology, metaphysics, philosophy of science, moral and political philosophy, aesthetics, and the philosophy of religion. The volume also traces the historical origins and consequences of Kant 's work. (shrink)

Kant’s distinction between analytic and synthetic judgments is best known through his metaphoric definition of an analytic judgment as one in which “the predicate B belongs to the subject A, as something which is contained in this subject A”. Although this is the most famous formulation of Kant’s distinction, what strikes a student most forcefully about Kant’s discussion of analyticity is the variety of different ways in which he explains the idea. One can identify passages which seem to make analyticity (...) depend upon containment, identity, contradiction, our way of knowing the judgment in question, our way of thinking the judgment in question, the function or role of the judgment in question. In addition to these six prima facie different conceptions of analyticity, there is also a question whether Kant intends his distinction to range over all judgments or only over subject-predicate judgments; if we apply these two alternatives to the six conceptions of analyticity, we have a total of twelve theories of analyticity contained in or suggested by Kant’s discussion. This is a bewildering situation indeed, and it is no wonder that subsequent discussions of analyticity have often lacked the decisiveness that one might wish for in matters of logic. (shrink)

I defend Kant’s definition of analyticity in terms of concept “containment”, which has engendered widespread scepticism. Kant deployed a clear, technical notion of containment based on ideas standard within traditional logic, notably genus/species hierarchies formed via logical division. Kant’s analytic/synthetic distinction thereby undermines the logico-metaphysical system of Christian Wolff, showing that the Wolffian paradigm lacks the expressive power even to represent essential knowledge, including elementary mathematics, and so cannot provide an adequate system of philosophy. The results clarify the extent to (...) which analyticity sensu Kant can illuminate the problem of a priori knowledge generally. (shrink)

Officially, for Kant, judgments are analytic iff the predicate is "contained in" the subject. I defend the containment definition against the common charge of obscurity, and argue that arithmetic cannot be analytic, in the resulting sense. My account deploys two traditional logical notions: logical division and concept hierarchies. Division separates a genus concept into exclusive, exhaustive species. Repeated divisions generate a hierarchy, in which lower species are derived from their genus, by adding differentia(e). Hierarchies afford a straightforward sense of containment: (...) genera are contained in the species formed from them. Kant's thesis then amounts to the claim that no concept hierarchy conforming to division rules can express truths like '7+5=12.' Kant is correct. Operation concepts ( ) bear two relations to number concepts: and are inputs, is output. To capture both relations, hierarchies must posit overlaps between concepts that violate the exclusion rule. Thus, such truths are synthetic. (shrink)

This edition contains the Critique of Aesthetic Judgement and Critique of Teleological Judgement. The introductions and notes that accompanied the translations in the original two volumes have now been dropped in order to make the translations available in a single volume.

James Van Cleve examines the main topics from Kant's Critique of Pure Reason, such as transcendental idealism, necessity and analyticity, space and time, substance and cause, noumena and things-in-themselves, problems of the self, and rational theology. He also discusses the relationship between Kant's thought and that of modern anti-realists, such as Putnam and Dummett. Because Van Cleve focuses upon specific problems rather than upon entire passages or sections of the Critique, he makes Kant's work more accessible to the serious student (...) and scholar. (shrink)
