cause of the ignorance, under the notion that it was in their power to prevent their ignorance, because they might have paid attention.
But perhaps a man is of such a character that he cannot attend to such things: still men are themselves the causes of having become such characters by living carelessly, and also of being unjust or destitute of self-control, the former by doing evil actions, the latter by spending their time in drinking and such-like; because the particular acts of working form corresponding characters, as is shown by those who are practising for any contest or particular course of action, for such men persevere in the acts of working.
As for the plea, that a man did not know that habits are produced from separate acts of working, we reply, such ignorance is a mark of excessive stupidity.
Furthermore, it is wholly irrelevant to say that the man who acts unjustly or dissolutely does not wish to attain the habits of these vices: for if a man wittingly does those things whereby he must become unjust he is to all intents and purposes unjust voluntarily; but he cannot with a wish cease to be unjust and become just. For, to take the analogous case, the sick man cannot with a wish be well again, yet in a supposable case he is voluntarily ill because he has produced his sickness by living intemperately and disregarding his physicians.
