One may, moreover, in agreement with Dr. Grasset, and also with the facts and common sense, admit that there are mentally sick persons, and that these persons vary as to the degree to which they are affected, that is to say, they are more or less conscious, more or less able to resist their impulses. The hypothesis of determinism cannot make us forget all the visible shades of difference between the normal individual and the typical madman. The normal man receives varied impressions, external and internal; some impel him to action, others hold him back: he establishes an equilibrium. Normal life is nothing but that,--a state of equilibrium, a static condition. The man who is termed abnormal is, on the contrary, more or less constantly out of balance. He is impelled by one force that is not counterbalanced by another: he falls. When the wind blows always from the same direction upon a row of pines, it bends them all in the same direction. If the wind, though violent, blows alternately from opposite directions, the trees remain erect. These rows of pines will provide us, not with the image, but with the schema of the normal and the abnormal man. Neither one nor the other,--and the man as little as the tree,--is responsible either for the origin, or the power, or the direction of the wind which bends them and straightens them in turn or, on the contrary, breaks them forever as if they were mere reeds; there remains however, the fact, that while the one kept itself erect in a healthy posture, despite occasionally rude shocks, the other, subjected to a constant pressure, bent over from day to day with its head nearer to the ground, or even, as the result of a more than usually violent tempest, broke altogether. It is a fact, and one must keep it in mind when he passes judgment upon trees or upon men. It is a fact, and that is all. Nevertheless, if the tree has been uprooted by a violent tempest, there is nothing left but to call the wood-cutters, who are the judges of trees. If they inquire into the cause of the disaster, it will be through pure curiosity; their business does not lie there; they know their duty and will perform it.
