In Chapter 4 of Science and Subjectivity, I offered several arguments critical of Professor Thomas Kuhn's views as expressed in his influential book The Structure of Scientific Revolutions. His recent replies to these criticisms seem to me so inadequate as to suggest that he, and therefore others as well, may have failed to grasp their full import. Accordingly, I shall, in the first part of this paper, briefly recapitulate my earlier arguments and offer a short rejoinder to Professor Kuhn's replies. (...) The second part of the paper will expand upon my earlier discussion to consider the basic metaphors of vision and revolution, offered by Kuhn to replace the traditional notion of deliberation. My argument here will be that these new metaphors are incongruous in critical respects, and my discussion will conclude by considering their relations to the contrast between understanding and accepting a theory.
