The moral or spiritual element in man is represented by the immortal steed which, like thumos in the Republic, always sides with the reason. Both are dragged out of their course by the furious impulses of desire. In the end something is conceded to the desires, after they have been finally humbled and overpowered. And yet the way of philosophy, or perfect love of the unseen, is total abstinence from bodily delights. 'But all men cannot receive this saying': in the lower life of ambition they may be taken off their guard and stoop to folly unawares, and then, although they do not attain to the highest bliss, yet if they have once conquered they may be happy enough. The language of the Meno and the Phaedo as well as of the Phaedrus seems to show that at one time of his life Plato was quite serious in maintaining a former state of existence. His mission was to realize the abstract; in that, all good and truth, all the hopes of this and another life seemed to centre. To him abstractions, as we call them, were another kind of knowledge--an inner and unseen world, which seemed to exist far more truly than the fleeting objects of sense which were without him. When we are once able to imagine the intense power which abstract ideas exercised over the mind of Plato, we see that there was no more difficulty to him in realizing the eternal existence of them and of the human minds which were associated with them, in the past and future than in the present. The difficulty was not how they could exist, but how they could fail to exist. In the attempt to regain this 'saving' knowledge of the ideas, the sense was found to be as great an enemy as the desires; and hence two things which to us seem quite distinct are inextricably blended in the representation of Plato.
