Yet surely, I said, this ferocity only comes from spirit, which, if rightly educated, would give courage, but, if too much intensified, is liable to become hard and brutal. That I quite think. On the other hand the philosopher will have the quality of gentleness. And this also, when too much indulged, will turn to softness, but, if educated rightly, will be gentle and moderate. True. And in our opinion the guardians ought to have both these qualities? Assuredly. And both should be in harmony? Beyond question. And the harmonious soul is both temperate and courageous? Yes. And the inharmonious is cowardly and boorish? Very true. And, when a man allows music to play upon him and to pour into his soul through the funnel of his ears those sweet and soft and melancholy airs of which we were just now speaking, and his whole life is passed in warbling and the delights of song; in the first stage of the process the passion or spirit which is in him is tempered like iron, and made useful, instead of brittle and useless. But, if he carries on the softening and soothing process, in the next stage he begins to melt and waste, until he has wasted away his spirit and cut out the sinews of his soul; and he becomes a feeble warrior. Very true. If the element of spirit is naturally weak in him the change is speedily accomplished, but if he have a good deal, then the power of music weakening the spirit renders him excitable;--on the least provocation he flames up at once, and is speedily extinguished; instead of having spirit he grows irritable and passionate and is quite impracticable. Exactly. And so in gymnastics, if a man takes violent exercise and is a great feeder, and the reverse of a great student of music and philosophy, at first the high condition of his body fills him with pride and spirit, and lie becomes twice the man that he was. Certainly. And what happens? if he do nothing else, and holds no con-a verse with the Muses, does not even that intelligence which there may be in him, having no taste of any sort of learning or enquiry or thought or culture, grow feeble and dull and blind, his mind never waking up or receiving nourishment, and his senses not being purged of their mists? True, he said. And he ends by becoming a hater of philosophy, uncivilized, never using the weapon of persuasion,--he is like a wild beast, all violence and fierceness, and knows no other way of dealing; and he lives in all ignorance and evil conditions, and has no sense of propriety and grace. That is quite true, he said. And as there are two principles of human nature, one the spirited and the other the philosophical, some God, as I should say, has given mankind two arts answering to them (and only indirectly to the soul and body), in order that these two principles (like the strings of an instrument) may be relaxed or drawn tighter until they are duly harmonised. That appears to be the intention.
