But the kind of definiteness and consistency introduced depends upon who introduces them. In a later passage [Footnote: op. cit., p. 133.] Dewey gives an example of how differently an experienced layman and a chemist might define the word metal. "Smoothness, hardness, glossiness, and brilliancy, heavy weight for its size … the serviceable properties of capacity for being hammered and pulled without breaking, of being softened by heat and hardened by cold, of retaining the shape and form given, of resistance to pressure and decay, would probably be included" in the layman's definition. But the chemist would likely as not ignore these esthetic and utilitarian qualities, and define a metal as "any chemical element that enters into combination with oxygen so as to form a base."
For the most part we do not first see, and then define, we define first and then see. In the great blooming, buzzing confusion of the outer world we pick out what our culture has already defined for us, and we tend to perceive that which we have picked out in the form stereotyped for us by our culture. Of the great men who assembled at Paris to settle the affairs of mankind, how many were there who were able to see much of the Europe about them, rather than their commitments about Europe? Could anyone have penetrated the mind of M. Clemenceau, would he have found there images of the Europe of 1919, or a great sediment of stereotyped ideas accumulated and hardened in a long and pugnacious existence? Did he see the Germans of 1919, or the German type as he had learned to see it since 1871? He saw the type, and among the reports that came to him from Germany, he took to heart those reports, and, it seems, those only, which fitted the type that was in his mind. If a junker blustered, that was an authentic German; if a labor leader confessed the guilt of the empire, he was not an authentic German.
