"No notion of primitive man's concept of the external world, his analysis of himself, of the nature of the godhead, etc., is possible unless it be recognized that, as among us, there exist, roughly speaking, two general types of temperament: the man of action and the thinker. ...the man of action predominates overwhelmingly. But this predomination carries with it a far greater significance among primitive people than among us for the very simple reason that the population in any specific group is so small. ...neither the man of action nor the thinker has much understanding of and still less sympathy for the other... The man of action, broadly characterized, is oriented toward the object, interested primarily in practical results, and indifferent to the claims and stirrings of his inner self. ...The thinker ...although he, too, is definitely desirous of practical results ...is nevertheless impelled by his whole nature to spend considerable time in analyzing his subjective states and attaches great importance both to their influence upon his actions and to the explanations ...The former is satisfied that the world exists and that things happen. Explanations are of secondary importance. ...He prefers an explanation in which the purely mechanical relation ...is specifically stressed. His mental rhythm ...is characterized by a demand for endless repetition ...or, at best, of events all of which are of the same general level. Change for him means essentially some abrupt transformation. Monotony holds no terrors for him. ...his mentality is written over the vast majority of myths and magical incantations. ...Now the rhythm of the thinker is quite different. ...He insists on a description couched either in terms of a gradual progress and evolution from one to many and from simple to complex, or on the postulation of a cause and effect relation."
