He belongs to both worlds, the natural and the spiritual.
He cannot shake off the natural and remain a man--to separate the two means death to man as we know him.

But there is a great difference between his position in the natural world and his position in the spiritual world.

He seems to be the last word in the world of nature, he has reached heights far beyond those reached by any other flesh and blood.

He is, so far as we know, the culminating point of natural evolution--the final possibility in the natural world.

But the stage of nature only represents the first stage in the development of the universe.
There is an infinitely higher stage of life, the spiritual life.
