3. NOMINALISM AND REALISM.—Hand in hand with the whole development of Scholasticism, there was developed the opposition between Nominalism and Realism, an opposition whose origin is to be found in the relation of Scholasticism to the Platonic and Aristotelian philosophy. The Nominalists were those who held that the conceptions of the universal (the universalia) were simple names, _flatus vocis_, representations without content and without reality. According to them there are no universal conceptions, no species, no class; every thing which is, exists only as separate in its pure individuality; there is, therefore, no pure thinking, but only a representation and sensuous perception. The Realists, on the other hand, taking pattern from Plato, held fast to the objective reality of the universals (_universalia ante rem_). These opposite directions appeared first between _Roscellinus_, who took the side of Nominalism, and _Anselm_, who advocated the Realistic theory, and it is seen from this time through the whole period of Scholasticism, though from the age of _Abelard_ (born 1079) a middle view, which was both Nominalistic and Realistic, held with some slight modifications the prominent place (_universalia in re_). According to this view the universal is only something thought and represented, though as such it is not simply a product of the representing consciousness, but has also its objective reality in objects themselves, from which it was argued we could not abstract it if it were not essentially contained in them. This identity of thought and being, is the fundamental premise on which the whole dialectic course of the Scholastics rests. All their arguments are founded on the claim, that that which has been syllogistically proved is in reality the same as in logical thinking. If this premise is overthrown, so falls with it the whole basis of Scholasticism; and there remains nothing more for the thinker to do, who has gone astray in his objectivity, but to fall back upon himself. This self-dissolution of Scholasticism actually appears with _William of Occam_ (died 1347), the most influential reviver of that Nominalism which had been so mighty in the beginning of Scholasticism, but which now, more victorious against a decaying than then against a rising form of culture, plucked away its foundation from the framework of Scholastic dogmatism, and brought the whole structure into inevitable ruin.
