Let me here quote a noble sentence, which has often given me much-needed help, and served to remind me that thought is after all as real a thing as matter, when I have been tempted to feel otherwise. It was written by a very wise and tender philosopher, William James, who was never betrayed by his own severe standard of truth and reality into despising the common dreams and aspirations of simpler men. He wrote: "I find it preposterous to suppose that if there be a feeling of unseen reality, shared by numbers of the best men in their best moments, responded to by other men in their deep moments, good to live by, strength-giving--I find it preposterous, I say, to suppose that the goodness of that feeling for living purposes should be held to carry no objective significance, and especially preposterous if it combines harmoniously with an otherwise grounded philosophy of objective truth." That is a very large and tolerant utterance, both in its suspension of impatient certainties and in its beautiful sympathy with all ardent visions that cannot clearly and convincingly find logical utterance. What I am trying to say in this little book is not addressed to professional philosophers or men of science, who are concerned with intellectual investigation, but to those who have to live life as it is, as the vast majority of men must always be. What I rather beg of them is not to be alarmed and bewildered by the statements either of scientific or religious dogmatists. No doubt we should like to know everything, to have all our perplexities resolved; but we have reached that point neither in religion nor in philosophy, nor even in science. We must be content not to know. But because we do not know, we need not therefore refuse to feel; there is no excuse for us to thrust the whole tangle away and out of sight, and just to do as far as possible what we like. We may admire and hope and love, and it is our business to do all three. The thing that seems to me--and I am here only stating a personal view--both possible and desirable, is to live as far as we can by the law of beauty, not to submit to anything by which our soul is shamed and insulted, not to be drawn into strife, not to fall into miserable fault-finding, not to allow ourselves to be fretted and fussed and agitated by the cares of life; but to say clearly to ourselves, "that is a petty, base, mean thought, and I will not entertain it; this is a generous and kind and gracious thought, and I will welcome it and obey it."
