William James, The Varieties of Religious Experience (1902):
The wisest of critics is an altering being, subject to the better insight of the morrow, and right at any moment, only “up to date” and “on the whole.” When larger ranges of truth open, it is surely best to be able to open ourselves to their reception, unfettered by our previous pretensions. “Heartily know, when half-gods go, the gods arrive.”
The fact of diverse judgments about religious phenomena is therefore entirely unescapable, whatever may be one’s own desire to attain the irreversible. But apart from that fact, a more fundamental question awaits us, the question whether men’s opinions ought to be expected to be absolutely uniform in this field. Ought all men to have the same religion? Ought they to approve the same fruits and follow the same leadings? Are they so like in their inner needs that, for hard and soft, for proud and humble, for strenuous and lazy, for healthy-minded and despairing, exactly the same religious incentives are required? Or are different functions in the organism of humanity allotted to different types of man, so that some may really be the better for a religion of consolation and reassurance, whilst others are better for one of terror and reproof? It might conceivably be so; and we shall, I think, more and more suspect it to be so as we go on. And if it be so, how can any possible judge or critic help being biased in favor of the religion by which his own needs are best met? He aspires to impartiality; but he is too close to the struggle not to be to some degree a participant, and he is sure to approve most warmly those fruits of piety in others which taste most good and prove most nourishing to him.
I am well aware of how anarchic much of what I say may sound. Expressing myself thus abstractly and briefly, I may seem to despair of the very notion of truth. But I beseech you to reserve your judgment until we see it applied to the details which lie before us. I do indeed disbelieve that we or any other mortal men can attain on a given day to absolutely incorrigible and unimprovable truth about such matters of fact as those with which religions deal. But I reject this dogmatic ideal not out of a perverse delight in intellectual instability. I am no lover of disorder and doubt as such. Rather do I fear to lose truth by this pretension to possess it already wholly. That we can gain more and more of it by moving always in the right direction, I believe as much as any one, and I hope to bring you all to my way of thinking before the termination of these lectures. Till then, do not, I pray you, harden your minds irrevocably against the empiricism which I profess.
