II. The World Conception of the Greek Thinkers

With Aristotle's focus on a spiritual soul the perspective toward a spiritual world in general is naturally given. The world picture of Aristotle stands before our contemplative eye in such a way that we see below the life of things and events, thus presenting matter and idea; the higher we lift our eye, the more we see vanish whatever bears a material character. Pure spiritual essence appears, representing itself to man as idea, that is, the sphere of the world in which deity as pure spirituality that moves everything has its being. The spiritual soul of man belongs to this world sphere; before it is united with a body-soul entity, it does not exist as an individual being but only as a part of the world spirit. Through this connection it acquires its individual existence separated from the world spirit and continues to live after the separation from the body as a spiritual being. Thus, the individual soul entity has its beginning with the human earthly life and then lives on as immortal. A preexistence of the soul before earth life is assumed by Plato but not by Aristotle. The denial of the soul's preexistence is as natural to Aristotle, who has the idea exist in the thing, as the opposite view is natural to Plato, who conceives of the idea as hovering over the thing. Aristotle finds the idea in the thing, and the soul acquires in its body what it is to be in the spirit world as an individuality.
