[F]ertilisation of the soul is the reason for the necessity of art. - Alfred North Whitehead

[W]e cannot think first and act afterwards. From the moment of birth we are immersed in action, and can only fitfully guide it by taking thought.

The Reformation was a popular uprising, and for a century and a half drenched Europe in blood. The beginnings of the Scientific movement were confined to a minority among the intellectual elite.… [T]he worst that happened to men of science was that Galileo suffered an honorable detention and a mild reproof, before dying peacefully in his bed. The way in which the persecution of Galileo has been remembered is a tribute to the quiet commencement of the most intimate change in outlook which the human race had yet encountered. Since a babe was born in a manger, it may be doubted whether so great a thing has happened with so little stir.

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.
