The warning is not directed against a man of straw. The attempt to derive the state, or any other social institution, from strictly “psychological” data is in point. Appeal to a gregarious instinct to account for social arrangements is the outstanding example of the lazy fallacy. Men do not run together and join in a larger mass as do drops of quicksilver, and if they did the result would not be a state nor any mode of human association. The instincts, whether named gregariousness, or sympathy, or the sense of mutual dependence, or domination on one side and abasement and subjection on the other, at best account for everything in general and nothing in particular. And at worst, the alleged instinct and natural endowment appealed to as a causal force themselves represent physiological tendencies which have previously been shaped into habits of action and expectation by means of the very social conditions they are supposed to explain. Men who have lived in herds develop attachment to the horde to which they have become used; children who have perforce lived in dependence grow into habits of dependence and subjection. The inferiority complex is socially acquired, and the “instinct” of display and mastery is but its other face. There are structural organs which physiologically manifest themselves in vocalizations as the organs of a bird induce song. But the barking of dogs and the song of birds are enough to prove that these native tendencies do not generate language. In order to be converted into language, native vocalization requires transformation by extrinsic conditions, both organic and extra-organic or environmental: formation, be it noted, not just stimulation. The cry of a baby can doubtless be described in purely organic terms, but the wail becomes a noun or verb only by its consequences in the responsive behavior of others. This responsive behavior takes the form of nurture and care, themselves dependent upon tradition, custom and social patterns. Why not postulate an “instinct” of infanticide as well as one of guidance and instruction? Or an “instinct” of exposing girls and taking care of boys?
