literal uniformity of nature requires. Activity-situations come, in short, each with an original touch. A 'principle' of free will if there were one, would doubtless manifest itself in such phenomena, but I never saw, nor do I now see, what the principle could do except rehearse the phenomenon beforehand, or why it ever should be invoked.

ED.] VII THE ESSENCE OF HUMANISM[105] Humanism is a ferment that has 'come to stay.'[106] It is not a single hypothesis or theorem, and it dwells on no new facts. It is rather a slow shifting in the philosophic perspective, making things appear as from a new centre of interest or point of sight. Some writers are strongly conscious of the shifting, others half unconscious, even though their own vision may have undergone much change. The result is no small confusion in debate, the half-conscious humanists often taking part against the radical ones, as if they wished to count upon the other side.[107] If humanism really be the name for such a shifting of perspective, it is obvious that the whole scene of the philosophic stage will change in some degree if humanism prevails. The emphasis of things, their foreground and background distribution, their sizes and values, will not keep just the same.[108] If such pervasive consequences be involved in humanism, it is clear that no pains which philosophers may take, first in defining it, and then in furthering, checking, or steering its progress, will be thrown away. It suffers badly at present from incomplete definition. Its most systematic advocates, Schiller and Dewey, have published fragmentary programs only; and its bearing on many vital philosophic problems has not been traced except by adversaries who, scenting heresies in advance, have showered blows on doctrines--subjectivism and scepticism, for example--that no good humanist finds it necessary to entertain. By their still greater reticences, the anti-humanists have, in turn, perplexed the humanists. Much of the controversy has involved the word 'truth.' It is always good in debate to know your adversary's point of view authentically. But the critics of humanism never define exactly what the word 'truth' signifies when they use it themselves. The humanists have to guess at their view; and the result has doubtless been much beating of the air. Add to all this, great individual differences in both camps, and it becomes clear that nothing is so urgently needed, at the stage which things have reached at present, as a sharper definition by each side of its central point of view.
