The success of the imaginative experiment is always to be tested by the applicability of its results beyond the restricted locus from which it originated. In default of such extended application, a generalization started from physics, for example, remains merely an alternative expression of notions applicable to physics. The partially successful philosophic generalization will, if derived from physics, find applications in fields of experience beyond physics. It will enlighten observation in those remote fields, so that general principles can be discerned as in process of illustration, which in the absence of the imaginative generalization are obscured by their persistent exemplification.

Explicitly in the verbal sentence, or implicitly in the

tion includes demonstrative elements. In fact each word, and each sym-
bolic phrase, is such an element, exciting the conscious prehension of some
entity belonging to one of the categories of existence.
