The writer of this book spent nine years of his life in colleges and universities; also he was brought up in a church. So he knows the orthodox teachings, he can say that he has given to the recognized wise men of the world every opportunity to tell him what they know. Then, being dissatisfied, he went to the unrecognized teachers, the enthusiasts and the "cranks" of a hundred schools. Finally, he thought for himself; he was even willing to try experiments upon himself. As a result, he has not found what he claims is ultimate or final truth; but he has what he might describe as a rough working draft, a practical outline, good for everyday purposes. He is going to have confidence enoughin you, the reader, to give you the hardest part first; that is, to begin with the great fundamental questions. What is life, and how does it come to be? What does it mean, and what have we to do with it? Are we its masters or its slaves? What does it oweus, and what do we owe to it? Why is it so hard, and do we have to stand its hardness? And can we really know about all these matters, or will we be only guessing? Can we trust ourselves to think about them, or shall we be safer if we believe what we aretold? Shall we be punished if we think wrong, and how shall we be punished? Shall we be rewarded if we think right, and will the pay be worth the trouble? Such questions as these I am going to try to answer in the simplest language possible. I would avoidlong words altogether, if I could; but some of these long words mean certain definite things, and there are no other words to serve the purpose. You do not refuse to engage in the automobile business because the carburetor and the differential are words offour syllables. Neither should you refuse to get yourself straight with the universe because it is too much trouble to go to the dictionary and learn that the word "phenomenon" means something else than a little boy who can play the piano or do long division in his head.
