In this paper we briefly examine and evaluate Quine’s physicalism. On the supposition, in accordance with Quine’s views, that there can be no change of any sort without a physical change, we argue that this point leaves plenty of room to understand and accept a limited autonomy of the special sciences and of other domains of disciplinary and common-sense inquiry and discourse. The argument depends on distinguishing specific, detailed programs of reduction from the general Quinean strategy of reduction by explication. (...) We argue that the details of the relations of particular sciences, disciplines and domains of discourse depend on empirical evidence and empirical-theoretical developments and that the generalized approach of reduction by explication is also subject to related empirical-theoretical constraints. So understood, physicalism lacks much of the controversial force and many of the implications sometimes associated with it. (shrink)

W. van Orman Quine is one of the leading philosophers in America today. His thinking, however, has received little attention from philosophers in continental Europe. This book is a systematic and critical account of Quine's philosophy which aims at isolating what is of lasting value in his work. Each of his major theses is submitted to a thorough examination both from within and from without his general standpoint. Quine's positions have changed a great deal over the years in response to (...) external criticism and to internal stresses and strains. These changes are described and assessed. Quine's rejection of the analytic-synthetic dichotomy is considered in the light of non-monotonic logic. The multi-farious versions of his holism are brought together and evaluated. Dummett's objection to the effect that holism is inconsistent with empiricism is refuted. lt is argued, however, that the controversial thesis of the indeterminacy of translation becomes implausible as soon as learnability constraints are brought to bear on the matter. Quine's new definition of logical truth in terms of grammatical structure is vindicated. It is shown how the apparent conflict between his earlier and his later views on ontology can be superseded. Can Quine hold a relativist view of ontology and at the same time maintain a non-relativist theory of truth? Can he hold that truth is internal to theories and claim that scientific theories are underdetermined by observational data without lending support to relativism? An affirmative answer to the first question is defended. It is argued, however, that Quine could not meet the second challenge. Quine's penetrating criticism of modal logic has prompted several research programs. Paul Gochet exhibits the interrelations between these programs and argues that Quine's objections against modal logic can be met without any commitment to doctrines such as essentialism. Of interest to: Philosophers, logicians, linguists. (shrink)

1. IMPORTANCE OF THE SUBJECT In 1900, in A Critical Exposition of the Philosophy of Leihniz, Russell made the following assertion: "That all sound philosophy should begin with an analysis of propositions is a truth too evident, perhaps, to demand a proof". 1 Forty years later, the interest aroused by this notion had not decreased. C. J. Ducasse wrote in the Journal of Philosophy: "There is perhaps no question more basic for the theory of knowledge than that of the nature (...) of 2 propositions and their relations to judgments, sentences, facts and inferences". Today, the great number of publications on the subject is proof that it is still of interest. One of the problems raised by propositions, the problem of deter mining whether propositions, statements or sentences are the primary bearers of truth and falsity, is even in the eyes of Bar-Hillel, "one of the major items that the future philosophy oflanguage will have to discuss". 3 gave a correct summary of the situation when he wrote in his Ph. Devaux Russell : Since Peano and Schroder who, in fact, adhered more faithfully to Boole's logic of classes, the logical and epistemological status of the proposition together with its analysis have not ceased to be the object of productive philosophical controversies. And especially so since the establishment of contemporary symbolic logic, the foundations 4 of which have been laid out by Russell and Whitehead. * 2. (shrink)

In this paper I shall examine the interrelationships holding between four of the main theses of Quine's philosophy. (1)Ho1ism (2)Underdetennination of scientific theories (3) Indeterminacy of translation (4) Ontological Relativity -/- These four doctrines have generated a lasting controversy: in one interpretation they seem to be false and in the other they are threatened to collapse into triviality. Moreover it has been claimed that they cannot be consistently upheld together. I shall argue, on the contrary, that they are true, original (...) and mutually consistent. (shrink)
