This is a note which appeals forcibly to every noble youth. It has been struck by the Hebrew Prophets and the Christian Apostles: by Savonarola and Fichte, and a host of heroic souls; but by no one more clearly and constrainingly than by Plato. It is the note of earnest and aggressive righteousness; without which no personality can be either sound or strong. The man who has never heard this summons to go forth and conquer the evils of the world without and of his own heart within him, in the name of a righteousness high above both his own attainment and the attainment of the world about him as the heavens are higher than the earth, is still in the nursery stage of personal development. On the other hand, there is danger in the very sharpness of the antithesis which Platonism makes between the higher and the lower. For the most part this danger is latent in Plato himself; though even in him it came out in his tendency to regard family life and private property as detrimental rather than serviceable to that development of character on which the larger devotion to the state, and the ideal order, must ultimately rest. In Neoplatonism, in the many forms of mysticism, in certain aspects of Christian asceticism, and notably in the numerous phases of what calls itself "New Thought" to-day, what was for the most part latent in Plato, becomes frankly explicit. In general it is a loosening of the ties that hold us to drudgery and homely duty; a weakening of the bonds that bind us to the men and women by our side, in order to gaze more serenely on the ineffable beyond the clouds. This developed Platonism admits that we must live after a fashion in this very imperfect world; but says our real conversation all the time must be in heaven. Individual people are but faulty, imperfect copies of the pattern of the perfect good laid up on high. We must buy and sell, work and play, laugh and cry, love and hate down here among the shadows; but we must all the time feed our souls on the good, the true, the beautiful, which these distorted human shadows only serve to hide. These Platonic lovers of something better than their husbands or wives, or associates or friends, go through the world with a serene smile, and an air of other-worldliness which, if we do not inquire too closely into their domestic life and business efficiency, we cannot but admire. They undoubtedly exert a tranquillising influence in their way, especially on those who are so fortunate as to behold them from a little distance. But they are not the most comfortable people to live with, as husband or wife, colleague or business partner. Louisa Alcott had this Platonic type in mind when she defined a philosopher as a man up in a balloon, with his family and friends having hold of the ropes, trying to pull him down to earth.
