Further, without a limiting Good there would be no reason in the world at large. This is founded on Aristotle's experience that reason is embedded in order and that it is the property of reason to have a limit. We have returned to the original proposition that reason discovers itself as part of human existence. Possibly, modern psychic disturbances are not caused by loss of the closed cosmos, but rather by the loss of truth in existence. Intellect is the instrument of self-interpretation as well as part of the structure interpreted.
Existence has noetic structure.
Intellect can transcend existence in various directions in search of knowledge. He is not the maker of this field of existents. Through illumination and transcendence, man finds himself in the situation from which questions of the origin and end of existence will arise. We must interpret the phenomenon of questioning itself. This analysis deals only with the demonstrations of classical and scholastic metaphysics, not with the whole structure of existence.
