A theory in its scientific context is not a static museum piece, but is always being extended and modified to account for new phenomena. - Mary Hesse

One of the main functions of an analogy or model is to suggest extensions of the theory by considering extensions of the analogy, since more is known about the analogy than is known about the subject matter of the theory itself... A collection of observable concepts in a purely formal hypothesis suggesting no analogy with anything would consequently not suggest either any directions for its own development.

This of course has always been the method of empirical science, which has been suspicious of deductive argumentation unchecked by reference to experiment; but in a more general sense, and outside the practice of science itself, scientists have sometimes been the greatest offenders in adhering to dogmatic ideas against all the evidence, especially when they have tended to limit 'experience' to laboratory experiment.
