It may be that I wish to do the things called good because I have been taught that I ought to do them. That teaching would be part of my environment Therefore the desire to be good, or better, and the knowledge that I can be good, or better, if I try, arise from and belong to heredity and environment. "But to try. Does not that show free will?" I have just proved that I try because I wish to succeed, and that environment has taught me that I cannot succeed without trying. "But does not the free will come in when I decide whether to do good or bad things?" No. For that has already been decided for me by heredity and environment, which have made me wish to do good things. So there is nothing wrong with that paragraph. The fault was in my critics, who had failed to understand the subject upon which they were trying to argue. A man can only try if heredity or environment causes him to want to try, and he can only keep on trying as long as heredity and environment cause him to keep on. One man is born with more talent than another. And one man is born with more industry, or with more ambition, or with more hope, patience, determination, than another. And the man who is more ambitious, or more patient, or more hopeful, or more determined, will try harder, and will try longer than the man who is less ambitious, or hopeful, or determined. Heredity settles that. But the man who has less of the qualities that make one try, may be spurred on by a teacher, a friend, or a powerful motive, and so may try harder and longer than the stronger man. As, for example, a man who has given up trying to succeed in some enterprise, may fall in love, and then the added desire to marry the woman he loves, may cause him to try harder than ever, and may lead him to succeed. But these things belong to his environment. Not only that, but they are a proof that environment can move a man when free will fails. For the man has a free will before he falls in love. But he loses heart, and does not succeed in his enterprise. But love, which is environment, supplies a new desire, and he does succeed. Why does he succeed? Because he wants to marry, and he cannot marry until he succeeds. This desire to marry comes of environment, and it rules the will, and compels the will to will a further effort. Is it not so? Although we say that man is the creature of heredity and environment, we do not say that he has no self-control. We only say that his self-control comes from heredity and environment, and is limited and controlled by heredity and environment. He can only "do as he likes" when heredity and environment cause him "to like," and he can only "do as he likes," so far and so long as heredity and environment enable him to go on. A man "can be good if he tries," but not unless heredity and environment cause him to wish to try.
