It is as it stands now the frank confession of what one man of the early Twentieth Century has found in life and himself, a confession just as frank as the limitations of his character permit; it is his metaphysics, his religion, his moral standards, his uncertainties and the expedients with which he has met them. On every one of these departments and aspects I write--how shall I put it?--as an amateur. In every section of my subject there are men not only of far greater intellectual power and energy than I, but who have devoted their whole lives to the sustained analysis of this or that among the questions I discuss, and there is a literature so enormous in the aggregate that only a specialist scholar could hope to know it. I have not been unmindful of these professors and this literature; I have taken such opportunities as I have found, to test my propositions by them. But I feel that such apology as one makes for amateurishness in this field has a lesser quality of self-condemnation than if one were dealing with narrower, more defined and fact-laden matters. There is more excuse for one here than for the amateur maker of chemical theories, or the man who evolves a system of surgery in his leisure. These things, chemistry, surgery and so forth, we may take on the reputation of an expert, but our own fundamental beliefs, our rules of conduct, we must all make for ourselves. We may listen and read, but the views of others we cannot take on credit; we must rethink them and "make them our own." And we cannot do without fundamental beliefs, explicit or implicit. The bulk of men are obliged to be amateur philosophers,--all men indeed who are not specialized students of philosophical subjects,--even if their philosophical enterprise goes no further than prompt recognition of and submission to Authority.
