In Hindu philosophy, the term Advaita refers to its idea that the true self, Atman, is the same as the highest metaphysical Reality (Brahman). More specifically, what is identical in God, according to Aquinas, is God's essence and God's actus essendi.[6] At about the same time, the nominalist philosopher William of Ockham argued, in Book I of his Summa Totius Logicae (Treatise on all Logic, written some time before 1327), that Categories are not a form of Being in their own right, but derivative on the existence of individuals. ./cache/en-wikipedia-org-4632.html ./txt/en-wikipedia-org-4632.txt
