Since the days of our racial childhood, our beliefs have been handed down from generation to generation, and they have persisted since in all ages it was forbidden to question their existence. Man has persuaded himself that it is so just because he has said it for so long and so often. The force of repetition is great; it is, in fact, taken by a vast majority of men as the equivalent of proof. Most men have to accept their religions ready made. Their daily tasks leave them no time or opportunity for a personal search. The toil for bread is incessant, there is not sufficient leisure to verify the sources of their religious beliefs. Moreover, the ecclesiastic's answers to the riddles of life are easier, by far, to grasp than the answers of science. These two factors, of innate mental inertia and force of repetition, are well manifested by the present tactics of advertising. The manufacturer of any product well knows that constant repetition and the dangling of his product before the eyes of the public will lead to a widespread acceptance of the advertising slogans propounded for his article. The force of so-called authority has aggravated this mental inertia. It takes a tremendous amount of will power and mental courage for any individual to assert an opinion that runs counter to the accepted mode of thinking. It is much easier and much more pleasant to give oneself passively to that delusion of grandeur, that delusion that pleasantly drugs the mind with the assumption that there is a supreme being who is personally interested in our well-being; a providence who, like a school master, at his pleasure dispenses rewards and punishments; as immortality, Heaven and Hell. So firmly has this become entrenched in the minds of men that the irrationalities which manifest themselves against such a conception make no impression. Schopenhauer well states, "Nothing is more provoking, when we are arguing against a man with reasons and explanations, and taking all pains to convince him, than to discover at last that he _will_ not understand, that we have to do with his _will_." The Martian, knowing the widespread extent of religious beliefs and their supposed influence in our daily lives, is prepared to find in our annals a vast literature that would attest to the overwhelming benefits that mankind had derived from his religious beliefs.
