One could pile up illustrations without limit; but this is enough to make clear the point, that it is perfectly futile to attempt to talk about "divine" rules for human conduct. Regardless of any ideas you may hold, or any wishes, you are forced at every hour of your life to apply your reason to the problems of your life, and you have no escape from the task of judging and deciding. All that you do is to judge right or to judge wrong; and if you judge wrong, you inflict misery upon yourself and upon all who come into contact with you. How much more sensible, therefore, to recognize the fact of moral and intellectual responsibility; to investigate the data of life with which you have to deal, the environment by which you are surrounded, and to train your judgment so that you will be able to fit yourself to it with quickness and certainty! "But," the believer in religion will say, "this leaves mankind without any guide or authority. How can human beings act, how can they deal with one another, if there are no laws, no permanent moral codes?" The answer is that to accept the idea of the evolution of morality does not mean at all that there will be no permanent laws and working principles. Many of the facts of life are fixed for all practical purposes--the purposes not merely of your life and my life, but the life of many generations. We are not likely to see in our time the end of the ancient Hebrew announcement that "the sins of the father are visited upon the children"; therefore it is possible for us to study out a course of action based upon the duty of every father to hand down to his children the gift of a sound mind in a sound body. The Catholic Church has had for a thousand years or more the "mortal sin" of gluttony upon its list; and today comes experimental science with its new weapons of research, and discovers autointoxication and the hardening of the arteries, and makes it very unlikely that the moral codes of men will ever fail to list gluttony as a mortal sin. Indeed, science has added to gluttony, not merely drunkenness, but all use of alcoholic liquor for beverage purposes; we have done this in spite of the manifest fact that the drinking of wine was not merely an Old Testament virtue, but a New Testament religious rite.
