Existence and Essence. How is it possible for this thing (a tree, or a piece of wood) which is being and nothing but being, to be opposed or totally different from that thing (man, or bird) which also is being and nothing but being? Every finite being is subject to two affirmations or principles of being which are real, incomplete parts, yet essentially unified and related as ACT and Potency.

(Memory is only the remembrance of the moment in time that we recall that the perception has occurred.) This image stored in the Imagination, is still material, particular, an individual copy of the material object witnessed. We would call it a change in chemical and neurological reactions in the brain. Aristotle knew that it was not an immaterial or spiritual phenomenon yet in its progress toward ideation or
