This lapse from natural unity has not escaped notice, and nations from the earliest times have asked the meaning of the wonderful division of the spirit against itself. No such inward disunion is found in nature: natural things do nothing wicked. The Mosaic legend of the Fall of Man has preserved an ancient picture representing the origin and consequences of this disunion. The incidents of the legend form the basis of an essential article of the creed, the doctrine of original sin in man and his consequent need of succour. It may be well at the commencement of logic to examine the story which treats of the origin and the bearings of the very knowledge which logic has to discuss. For, though philosophy must not allow herself to be overawed by religion, or accept the position of existence on sufferance, she cannot afford to neglect these popular conceptions. The tales and allegories of religion, which have enjoyed for thousands of years the veneration of nations, are not to be set aside as antiquated even now. Upon a closer inspection of the story of the Fall we find, as was already said, that it exemplifies the universal bearings of knowledge upon the spiritual life. In its instinctive and natural stage, spiritual life wears the garb of innocence and confiding simplicity: but the very essence of spirit implies the absorption of this immediate condition in something higher. The spiritual is distinguished from the natural, and more especially from the animal, life, in the circumstance that it does not continue a mere stream of tendency, but sunders itself to self-realisation. But this position of severed life has in its turn to be suppressed, and the spirit has by its own act to win its way to concord again. The final concord then is spiritual; that is, the principle of restoration is found in thought, and thought only. The hand that inflicts the wound is also the hand which heals it.
