The most ancient parts of truth . . . also once were plastic. They also were called true for human reasons. They also mediated between still earlier truths and what in those days were novel observations. Purely objective truth, truth in whose establishment the function of giving human satisfaction in marrying previous parts of experience with newer parts played no role whatsoever, is nowhere to be found. The reasons why we call things true is the reason why they are true, for to be true means only to perform this marriage-function.

William JamesThe war-function has grasped us so far; but the constructive interests may some day seem no less imperative, and impose on the individual a hardly lighter burden.
