Whatever be his origin, man comes upon the stage of being bearing within him a great and far-reaching destiny. There is in him, as Browning says, 'a tendency to God.' He is not simply what he is now, but all that he is yet to be. II. Assuming, then, the inherent spirituality of man, we may now proceed to examine his moral consciousness with a view to seeing how its various constituents form what we have called the substratum of the Christian life. {61} 1. We must guard against seeming to adopt the old and discredited psychology which divides man into a number of separate and independent faculties. Man is not made like a machine, of a number of adjusted parts. _He is a unity_, a living organism, in which every part has something of all the others; and all together, animated by one spirit, constitute a Living whole which we call personality. While the Bible is rich in terms denoting the different constituents of man, neither the Old Testament nor the New regards human nature as a plurality of powers. A bind of unity or hierarchy of the natural faculties is assumed, and amid all the difference of function and variety of operation it is undeniable that the New Testament writers generally, and particularly St. Paul, presuppose a unity of consciousness--a single ego, or Soul. It is unnecessary to discuss the question, much debated by Biblical psychologists, as to whether the apostle recognises a threefold or a twofold division of man.[14] Our view is that he recognised only a twofold division, body and soul, which, however, he always regarded as constituting a unity, the body itself being psychical or interpenetrated with spirit, and the spirit always acting upon and working through the physical powers. Man is a unique phenomenon in the world. Even on his physical side he is not a piece of dead matter, but is instinct through and through with spirit. And on his psychical side he is not an unsubstantial wraith, but a being inconceivable apart from outward embodiment. Perhaps the most general term which we may adopt is _psyche_ or Soul--the living self or vital and animating principle which is at once the seat of all bodily sensation and the source of the higher cognitive faculties.
