I assess Churchland's views on folk psychology and conceptual thinking, with particular emphasis on the connection between these topics.

(This insularity was further promoted by the guileless duplicity of scholars in other fields, who were all too prepared to bequeath "the problem of ...

In this sequence of philosophical essays about natural science, the author argues that fundamental explanatory laws, the deepest and most admired successes of modern physics, do not in fact describe regularities that exist in nature. Cartwright draws from many real-life examples to propound a novel distinction: that theoretical entities, and the complex and localized laws that describe them, can be interpreted realistically, but the simple unifying laws of basic theory cannot.

First published in 1978, this reissue presents a seminal philosophical work by professor Putnam, in which he puts forward a conception of knowledge which makes ethics, practical knowledge and non-mathematic parts of the social sciences just as much parts of 'knowledge' as the sciences themselves. He also rejects the idea that knowledge can be demarcated from non-knowledge by the fact that the former alone adheres to 'the scientific method'. The first part of the book consists of Professor Putnam's John Locke (...) lectures, delivered at the University of Oxford in 1976, offering a detailed examination of a 'physicalist' theory of reference against a background of the works of Tarski, Carnap, Popper, Hempel and Kant. The analysis then extends to notions of truth, the character of linguistic enquiry and social scientific enquiry in general, interconnecting with the great metaphysical problem of realism, the nature of language and reference, and the character of ourselves.

A study in the philosophy of science, proposing a strong form of the doctrine of scientific realism' and developing its implications for issues in the philosophy of mind.

This paper develops lines of criticism directed at two currently popular versions of anti-realism: the putnam-rorty-kuhn version that is centered on an acceptance theory of truth, and the van fraassen version that is centered on empiricist strictures over warranted beliefs. the paper continues by elaborating and extending a stance, called "the natural ontological attitude", that is neither realist nor anti-realist.

We have seen that the operational imperative is a prescriptive thesis about formulations of theories which imposes restrictions on the sorts of theories science may employ. We assessed the operational imperative by investigating a number of relationships holding between theory formulations, theories, physical systems, and phenomena, and then applying our findings to the operational imperative. These applications showed that the operational definitions required by the operational imperative were not definitions at all, being rather statements of putative empirical regularities holding between (...) particulars which in effect are formulations of empirically true or false theories. From this fact it followed that the supposed epistemic pay-offs of following the operational imperative fail to accrue: Operational definitions do not enable one to go deductively from knowledge of observables to knowledge of unobservables, and operational definitions do not provide a means for testing theories about unobservable phenomena. As such the operational imperative should be rejected in both its weak and strong versions. However, we did discover a grain of truth in the observational imperative — namely that theories with non-observable parameters are testable only if these parameters have observable manifestations. But that grain of truth does not lead to the operational imperative as typically advanced unless one embraces certain epistemological theories about observation which recent work on observation makes highly doubtful.
