In this book van Fraassen develops an alternative to scientific realism by constructing and evaluating three mutually reinforcing theories.

This essay contains a partial exploration of some key concepts associated with the epistemology of realist philosophies of science. It shows that neither reference nor approximate truth will do the explanatory jobs that realists expect of them. Equally, several widely-held realist theses about the nature of inter-theoretic relations and scientific progress are scrutinized and found wanting. Finally, it is argued that the history of science, far from confirming scientific realism, decisively confutes several extant versions of avowedly 'naturalistic' forms of scientific (...) realism.

The modern discussion on the concept of truthlikeness was started in 1960. In his influential Word and Object, W. V. O. Quine argued that Charles Peirce's definition of truth as the limit of inquiry is faulty for the reason that the notion 'nearer than' is only "defined for numbers and not for theories". In his contribution to the 1960 International Congress for Logic, Methodology, and Philosophy of Science at Stan­ ford, Karl Popper defended the opposite view by defining a compara­tive (...) notion of verisimilitude for theories. The concept of verisimilitude was originally introduced by the Ancient sceptics to moderate their radical thesis of the inaccessibility of truth. But soon verisimilitudo, indicating likeness to the truth, was confused with probabilitas, which expresses an opiniotative attitude weaker than full certainty. The idea of truthlikeness fell in disrepute also as a result of the careless, often confused and metaphysically loaded way in which many philosophers used - and still use - such concepts as 'degree of truth', 'approximate truth', 'partial truth', and 'approach to the truth'. Popper's great achievement was his insight that the criticism against truthlikeness - by those who urge that it is meaningless to speak about 'closeness to truth' - is more based on prejudice than argument.

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

The concept of metaphor as primarily a vehicle for conveying ideas, even if unusual ones, seems to me as wrong as the parent idea that a metaphor has a special meaning. I agree with the view that metaphors cannot be paraphrased, but I think this is not because metaphors say something too novel for literal expression but because there is nothing there to paraphrase. Paraphrase, whether possible or not, inappropriate to what is said: we try, in paraphrase, to say it (...) another way. But if I am right, a metaphor doesn't say anything beyond its literal meaning . This is not, of course, to deny that a metaphor has a point, nor that that point can be brought out by using further words. . . . My disagreement is with the explanation of how metaphor works its wonders. To anticipate: I depend on the distinction between what words mean and what they are used to do. I think metaphor belongs exclusively to the domain of use. It is something brought off by the imaginative employment of words and sentences and depends entirely on the ordinary meanings of those words and hence on the ordinary meanings of the sentences they comprise.

1. It is a commonplace that contemporary empiricism, or antimetaphysical philosophy, at least in this country, is a re-statement of the essentials of Hume's position with the aid of the more complete analysis of a priori reasoning provided by logicians within the last fifty years; what logical empiricism has most substantially added to Hume's sceptical method is the means of stating and applying his distinction between purely analytic sentences and sentences conveying information about matters of fact more precisely than he (...) was able to state or apply it. It was Hume's governing purpose in every part of his writing to defend what is now generally called the language of common-sense, which is essentially what he called natural belief, against every kind of philosophical theory, whether rationalist or professedly sceptical. By “philosophical theory” is meant in this context any attempt by the use of logical or a priori arguments either to justify or to amend our common-sense beliefs or assertions; Hume tries to show that all such attempts are mistaken in logic and ineffective in fact. The work of the genuine sceptic, who is the true philosopher, is repeatedly to draw attention to the limits of human reason; to draw attention to the limits of human reason is to point to the logical impossibility of answering philosophical demands for some general, and therefore non-empirical, justification of our natural beliefs; such demands involve the substituting of some single, imposed criterion of justification in the place of the various and shifting criteria which we in fact habitually use.
