Abstract Taking the integrated viewpoints of causal theory of reference, cognitive science and the notion of correspondence principles from physics, this paper addresses the problems of creativity, the nature of visual imagery and the manner in which science progresses.

I propose to support these replies with actual episodes in late nineteenth and twentieth century physics. The historical record reveals that meaning does change but not in the Kuhnian manner which is tied to descriptive theories of meaning. A necessary part of this discussion is commentary on realist versus antirealist conceptions of science.
