Abstract
Bergmann advocated a universal realism different from that of Plato. His universals are different, and the fundamental tie connecting universals to particulars is also in many respects different from Plato's participation. Since Bergmann takes universals to be perceptible, it makes sense to argue empirically for the existence of the fundamental tie of exemplification. He holds that exemplification ties universals and particulars together into facts. However, finally he drops fundamental ties and attributes to diads of diversity the togetherness of universals and particulars, though he is very reluctant to give up the principle that complexes need ties to give them unity. Analyzing the ontological tradition, Bergmann claims that it mostly mistook a function for a fundamental tie.
