of abstract universals, which are in one sense everywhere and in another nowhere, in one sense at all times and in another at no time, the things about which the historian reasons are not abstract but concrete, not universal but individual, not indifferent to space and time but having a where and a when of their own, though the where need not be here and the when cannot be now. History, therefore, cannot be made to square with theories according to which the object of knowledge is abstract and changeless, a logical entity towards which the mind may take up various attitudes.
