and that it lies between two faulty states, one in the way of excess and another in the way of defect, and that it is so because it has an aptitude to aim at the mean both in feelings and actions, all this has been set forth fully and sufficiently.
And so it is hard to be good: for surely hard it is in each instance to find the mean, just as to find the mean point or centre of a circle is not what any man can do, but only he who knows how: just so to be angry, to give money, and be expensive, is what any man can do, and easy: but to do these to the right person, in due proportion, at the right time, with a right object, and in the right manner, this is not as before what any man can do, nor is it easy; and for this cause goodness is rare, and praiseworthy, and noble.
Therefore he who aims at the mean should make it his first care to keep away from that extreme which is more contrary than the other to the mean; just as Calypso in Homer advises Ulysses,

because of the two extremes the one is always more, and the other less, erroneous; and, therefore, since to hit exactly on the mean is difficult, one must take the least of the evils as the safest plan; and this a man will be doing, if he follows this method.
1109bWe ought also to take into consideration our own natural bias; which varies in each man's case, and will be ascertained from the pleasure and pain arising in us.

But in all cases we must guard most carefully against what is pleasant, and pleasure itself, because we are not impartial judges of it.
We ought to feel in fact towards pleasure as did the old counsellors towards Helen, and in all cases pronounce a
