Everything is united and unified in the Ego, and the Ego unites and unifies everything in man. Therein lies the profound problem of the human Ego. Man certainly has a mind. He also has a body. Contradictory attributes seem to exist in one and the same Ego.
Man is, in many respects, like a jigsaw puzzle.
Yet the two major portions of the complete picture, namely, body and mind synthesized in the Ego, do not seem to match. Philosophers, by a large, find it extremely difficult to effect the synthesis. The problem is, without doubt, not an easy one to solve. Many solutions have been offered. The best way to arrive at the correct solution will be to view the problem in its historical setting.
