Another test of the genuineness of what is expressed in literature is its truth to life. Here again we tread upon ground somewhat uncertain, since truth is as elusive as a sunbeam, and to no two human beings the same. Yet while the meaning of life is not the same to any two who walk under the heavens, there are certain broad principles which all men recognize. The eternal facts of life and of death, of love and of hate, the instinct of self-preservation, the fear of pain, the respect for courage, and the enthrallment of passion,--these are laws of humanity so universal that we assume them to be known to all mankind. We cannot believe that any mortal can find that true to his imagination which ignores these unvarying conditions of human existence. He who writes what is untrue to humanity cannot persuade us that he writes what is true to himself. We are sure that those impossible heroes of Ouida, with their superhuman accomplishments, those heroines of beauty transcendently incompatible with their corrupt hearts, base lives, and entire defiance of all sanitary laws, were no more real to their author than they are to us. Conviction springs from the imagination, and imagination is above all else the realizing faculty. It is idle to say that a writer imagines every extravagant and impossible whimsy which comes into his head. He imagines those things, and those things only, which are real to his inner being; so that in judging literature the question to be settled is: Does this thing which the author tells, this emotion which he expresses, impress us as having been to him when he wrote actual, true, and absolutely real? To unimaginative persons it might seem that I am uttering nonsense. It is not possible for a man without imagination to see how things which are invented by the mind should by that same mind, in all sanity, be received as real. Yet that is precisely what happens. No one, I believe, produces real or permanent literature who is not capable of performing this miracle; who does not feel to be true that which has no other being, no other place, no other significance save that which it derives from the creative power of his own inner sense, working upon the material furnished by his perception of the world around him. This is the daily miracle of genius; but it is a miracle shared to some extent by every mortal who has the faintest glimmer of genuine imagination.
