Abstract

Like most philosophers, Laudan [7] believes that by and large science makes cognitive progress and that the development of science is more or less rational. His book deals with two major problems:(a)In what sense does science progress? What is scientific progress?(b)Wherein lies the rationality of the growth of science? What is scientific rationality?In the main body of this paper, I first summarize and evaluate some of Laudan’s criticisms of his predecessors. Then I outline and criticize Laudan’s own theory of scientific progress and scientific rationality. In the Postscript I sketch my own views concerning the issue of changes in the canons of scientific rationality and the problem of using history to evaluate normative theories of scientific rationality.
