Naturalism holds that there is no higher access to truth than empirically testable hypotheses. Still it does not repudiate untestable hypotheses. They fill out interstices of theory and lead to further hypotheses that are testable.A hypothesis is tested by deducing, from it and a background of accepted theory, some observation categorical that does not follow from the background alone. This categorical, a generalized conditional compounded of two observation sentences, admits in turn of a primitive experimental test.The observation sentences themselves, like (...) ape cries and bird calls, are in holophrastic association with ranges of neural intake. Denotation of determinate objects figures neither in this association nor in deducing the categorical from the scientific hypotheses. Hence the indeterminacy of reference; ontology is purely auxiliary to the structure of theory. Truth, however, is seen still as transcendent at least in this sense: we say of a superseded scientific theory not that it ceased to be true, but that it is found to have been false. (shrink)

[From the article's Introduction]: The main topic of the article is the Western metaphilosophy of the last hundred years or so. But that topic is broached via a sketch of some earlier Western metaphilosophies. (In the case of the sketch, ‘Western’ means European. In the remainder of the article, ‘Western’ means European and North American. On Eastern meta­philosophy, see the entries filed under such heads as ‘Chinese philosophy’ and ‘Indian philosophy’.) Once that sketch is in hand, the article defines the (...) notion of metaphilosophy and distinguishes between explicit and implicit metaphilosophy. Then there is a consideration of how metaphilosophies might be categorized and an outline of the course of the remainder of the article. (shrink)

QUINE'S PHILOSOPHICAL WRITINGS are for the most part contained in two collections of essays, From a Logical Point of View and recently The Ways of Paradox, and in an important book, Word and Object. The present survey will be restricted to views expressed in these three volumes, although Quine's work in logic is continuous with his work in philosophy. The present Part One describes and defends Quine's views about meaning. The following Part Two does the same for his views on (...) other subjects, especially ontology and epistemology. The two parts are related in a way to be explained in Part Two. (shrink)

The qualities that distinguished him in any discussion are on clear display in this volume, which features him in dialogue with his predecessors and peers, his ...

SummaryMetatheory may be pursued immanently, i.e., within the object language, or transcendently in metalanguages. Immanently, the hierarchy of metalanguages gives way to a hierarchy of predicates. The immanent approach accentuates the symmetry between Russell's paradox and Cantor's theorem: class shortage versus predicate shortage. Appeal to metatheoretic models, in defining logical truth, gives way to appeal to substitutions of expressions of the object language. Can this be said also of set‐theoretic truth, despite predicate shortage? Equivalently: is substitutional quantification unscathed by predicate (...) shortage? Anyway substitutional quantification balks at impredicative cases. (shrink)

This chapter compares and contrasts Quine’s naturalism with the versions of two post-Quineans on the nature of science, logic, and mathematics. The role of indispensability in the philosophy of mathematics is treated in detail.

At its origins, analytic philosophy is an interest in language, science, logic, analysis, and a systematic rather than a historical approach to philosophical problems. Early analytic philosophers were famous for making clear conceptual distinctions and for couching them in comprehensible and lucid sentences. It is argued that this situation is changing, that analytic philosophy is turning into its mirror image and is thereby becoming more like the kind of philosophy that it used to oppose.
