money, but they act like people who refuse to run because they might stumble, or to throw because they might throw wide of the mark, or object to sing altogether because they might make a false note. For as in sounds music does not create melody by the banishment of sharps and flats, and as in bodies the art of the physician procures health not by the doing away of cold and heat but by their being blended in due proportions and quantities, so is victory won in the soul by the powers and motions of the passions being reduced by reason to moderation and due proportion. For excessive grief or fear or joy in the soul (I speak not of mere joy grief or fear), resembles a body swollen or inflamed. And Homer when he says excellently, "The brave man's colour never changes, nor Is he much frightened,"[245] does not take away all fear but only excessive fear, that bravery may not become recklessness, nor confidence foolhardiness. So also in regard to pleasure we must do away with excessive desire, and in regard to vengeance with excessive hatred of evil. For so in the former case one will not be apathetic but temperate, and in the latter one will not be savage or cruel but just. But if the passions were entirely removed, supposing that to be possible, reason would become in many duller and blunter, like the pilot in the absence of a storm. And no doubt it is from having noticed this that legislators try to excite in states ambition and emulation among their townsmen, and stir up and increase their courage and pugnacity against enemies by the sound of trumpets and flutes. For it is not only in poems, as Plato says, that he that is inspired by the Muses, and as it were possessed by them, will laugh to shame the plodding artist, but also in fighting battles passion and enthusiasm will be irresistible and invincible, such as Homer makes the gods inspire men with, as in the line, "Thus speaking he infused great might in Hector, The shepherd of the people."[246] and, "He is not mad like this without the god,"[247]
