By injustice I mean the dominion of anger and fear, pleasure and pain, envy and desire, in the soul, whether doing harm or not: by justice I mean the rule of the opinion of the best, whether in states or individuals, extending to the whole of life; although actions done in error are often thought to be involuntary injustice.

No controversy need be raised about names at present; we are only desirous of fixing in our memories the heads of error.

And the pain which is called fear and anger is our first head of error; the second is the class of pleasures and desires; and the third, of hopes which aim at true opinion about the best;--this latter falls into three divisions (i.e.( 1) when accompanied by simple ignorance, (2) when accompanied by conceit of wisdom combined with power, or (3) with weakness), so that there are in all five.
