And secondly we must consider, each for himself, what we are most prone to—for different natures are inclined to different things—which we may learn by the pleasure or pain we feel. And then we must bend ourselves in the opposite direction; for by keeping well away from error we shall fall into the middle course, as we straighten a bent stick by bending it the other way.
But in all cases we must be especially on our guard against pleasant things, and against pleasure; for we can scarce judge her impartially. And so, in our behaviour towards her, we should imitate the behaviour of the old counsellors towards Helen, 32 and in all cases repeat their saying: if we dismiss her we shall be less likely to go wrong.
This then, in outline, is the course by which we shall best be able to hit the mean.
