One mark of the destructive forces of the Church was the revival of nominalism, for which William of Ockham is mainly responsible.

Universals, for Augustine, are essences which do not exist without being in the world, but which may be arrived at without a supposed existence.
William of Ockham takes an alternative approach called nominalism. He asserts that "no universal is a subject existing outside of the mind", maintaining...
