Because we cannot discover God’s throne in the sky with a radiotelescope or establish (for certain) that a beloved father or mother is still about in a more or less corporeal form, people assume that such ideas are “not true.” I would rather say that they are not “true” enough, for these are conceptions of a kind that have accompanied human life from prehisotric times, and that still break through into consciousness at any provocation.
Modern man may assert that he can dispense with them, and he may bolster his opinion by insisting that there is no scientifc evidence of their truth. Or he may even regret the loss of his convictions. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no means of proving immortality), why should we bother about evidence? Even if we did not know by reason our need for salt in our food, we should nonetheless profit from it’s use. We might argue that the use of salt is a mere illusion of taste or a superstition, but it would still constribute to our well-being. Why, then, should we deprive ourselves of views that would prove helpful in crises and would give a meaning to our existence?
And how do we know that such ideas are not true? Many people would agree with me if I stated flatly that such ideas are probably illusions. What they fail to realize is that the denial is as impossible to “prove” as the assertion of religious belief. We are entirely free to choose which point of view we take; it will in any case be an arbitrary decision.
There is, however, a strong empirical reason why we should cultivate thoughts that can never be proved. It is that they are known to be useful. Man positively needs general ideas and convictions that will give meaning to his life and enable him to find a place for himself in the universe. He can stand the most incredible hardships when he is convinced that they make sense; he is crushed when, on top of all his misfortunes, he has to admit that he is taking part in a “tale told by an idiot.”
