Abstract

This paper considers criticisms of the author's Science and Scepticism advanced by Fred D' Agostino, Graham Oddie, Elie Zahar, Alan Musgrave, and John Worrall. The criticisms concern the following topics: the aim of science, unified theoryhood, the empirical basis, corroboration by already known evidence, the idea that scientific theories need be no more than possibly true, and the pragmatic problem of induction. Various clarifications and improvements result, and on the last topic the author significantly modifies his position
