It may be that thus to interpret Plato is to do him an injustice. It has been sometimes said that his division of parts or kinds of soul—or his distinction between its fighting horses—tends to destroy the unity of mental life. But perhaps this was exactly what he wanted to convey. There are—we may paraphrase his meaning—three kinds of human being, three types of human life. There is the man or the life of appetite and the flesh: there is the man of noble emotion and energetic depth of soul: there is the life of reasonable pursuits and organised principle. Or, we may take his meaning to be that there are three elements or provinces of mental life, which in all except a few are but imperfectly coherent and do not reach a true or complete unity. Some unity there always is: but in the life of mere appetite and impulse, even when these impulses are our nobler sentiments of love and hatred, the unity falls very far short. Or, as he puts the theme elsewhere, the soul has a passion for self-completion, a love of beauty, which in most is but a misleading lust. It is the business of the philosophic life to re-create or to foster this unity: or philosophy is the persistent search of the soul for its lost unity, the search to see that unity which is always its animating principle, its inner faith. When the soul has reached this ideal—if it can be supposed to attain it (and of this the strong-souled ancient philosophers feel no doubt),—then a change must take place. The love of beauty is not suppressed; it is only made self-assured and its object freed from all imperfection. It is not that passion has ceased; but its nature is so transfigured, that it seems worthy of a nobler name, which yet we cannot give. To such a life, where battle and conflict are as such unknown, we cannot longer give the title of life: and we say that philosophy is in life a rehearsal of death(70). And yet if there be no battle, there is not for that reason mere inaction. Hence, as the Republic concludes, the true philosopher is the complete man. He is the truth and reality which the appetitive and emotional man were seeking after and failed to realise. It is true they at first will not see this. But the whole long process of philosophy is the means to induce this conviction. And for Plato it remains clear that through experience, through wisdom, and through abstract deduction, the philosopher will justify his claim to him who hath ears to hear and heart to understand. If that be so, the asceticism of Plato is not a mere war upon flesh and sense as such, but upon flesh and sense as imperfect truth, fragmentary reality, which suppose themselves complete, though they are again and again confuted by experience, by wisdom, and by mere calculation,—a war against their blindness and shortsightedness.
