but many of our writers come to life with preconceived ideas deeply affecting their delineation of it. The picture no longer seems true because we feel that a false theory has prevented the artist from viewing life concretely and clearly. We could, for example, accept as natural and inevitable the ending of _Tess of the D'Urbervilles_, if Hardy had not presented it as an illustration of the cruel sport of the gods. As it stands with the author's commentary, we suspect that the girl's fate might have been different,--that perhaps he gave it this turn in order to prove his theory of life. This fault is especially flagrant in the theory-ridden fiction of to-day. Determination through the past is overemphasized as against the influence of present, novel factors in a growing experience; heredity is given undue weight as against the inborn originality of personality and the uniqueness acquired through unique experiences; the influence of sensual motives is stressed at the expense of the moral; and so on through all the other abstractions and insufficiencies of "scientific" novel writing. The writer may well profit by everything he can learn from science; but he should not let his knowledge prevent him from seeing life concretely and as a whole. The literary man's science and philosophy are bound to be condemned by the expert, but his concrete delineations of life based on direct observation and vivid sympathy and imagination are impeccable. His theories may be false, but these will always be true. Nothing can take their place in fiction. It is they which give enduring value to such tales as _Morte d'Arthur_, despite all the crudity of the intellectual background. Reflections upon life may become matter for literature in the essay, quite apart from any story. But the essay, like the story, unless it is to compete at a disadvantage with science and philosophy, must rely upon first-hand personal acquaintance with life, and artistic expression. The more abstract and theoretical it becomes, the more precarious its worth. I do not mean that the essayist may not generalize, but his generalizations should be limited to the scope of his experience of life. I do not mean that he should not philosophize, but his philosophy should be, like Goethe's or Emerson's, an expression of intuition and faith. Properly, the literary essay is a distinct artistic genre--the expression of a concrete _thinking_ personality, and its value consists in the living wisdom it contains. Such essays as those of a Montaigne or a La Rochefoucauld make excellent materials for the social sciences, and can never be displaced by them as sources of knowledge of life.
