" On contact with sensuous experience, the intellect is able to generate first principles, and, with their help, it gradually builds up what it knows. But it is thus able to construct truth only because it is itself a participation in Truth. The mind is the light of divine truth -- analogically speaking, by way of participation. It is a participated likeness of the uncreated light in which the ideas of all things dwell. "
