though it might be clouded and forgotten, could never be entirely effaced. And when Plato tells us, at the close of his career, that God, far more than any individual man, is the measure of all things,[133] who can doubt that he had already learned to identify the human and divine essences in the common notion of a universal soul? The germ of this new dogmatism was present in Plato’s mind from the very beginning, and was partly an inheritance from older forms of thought. The _Apologia_ had reproduced one important feature in the positive teaching of Socrates—the distinction between soul and body, and the necessity of attending to the former rather than to the latter: and this had now acquired such significance as to leave no standing-room for the agnosticism with which it had been incompatible from the first. The same irresistible force of expansion which had brought the human soul into communion with absolute truth, was to be equally verified in a different direction. Plato was too much interested in practical questions to be diverted from them long by any theoretical philosophy; or, perhaps, we should rather say that this interest had accompanied and inspired him throughout. It is from the essential relativity of mind, the profound craving for intellectual sympathy with other minds, that all mystical imaginations and super-subtle abstractions take rise; so that, when the strain of transcendent absorption and ecstasy is relaxed under the chilling but beneficent contact of earthly experience, they become condensed into ideas for the reconstitution of life and society on a basis of reciprocity, of self-restraint, and of self-devotion to a commonwealth greater and more enduring than any individual, while, at the same time, presenting to each in objective form the principle by virtue of which only, instead of being divided, he can become reconciled with himself. Here we have the creed of all philosophy, whether theological, metaphysical, or positive, that there is, or that there should be, this threefold unity of feeling, of action, and of thought, of the soul, of society, and of universal existence, to win which is everlasting life, while to be without it is everlasting death. This creed must be re-stated and re-interpreted at every revolution of thought. We have to see how it was, for the first time, stated and interpreted by Plato.
