It is a false dichotomy to think of Nature and Man. Mankind is a factor in Nature which exhibits in its most intense form the plasticity of Nature. - Alfred North Whitehead

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.

A duration is a concrete slab of nature limited by simultaneity which is an essential factor disclosed in sense-awareness.

No member of a crew is praised for the rugged individuality of his rowing.
