“ They are all judgements, and that, too, judgements about things that lie outside the province of moral purpose, assumed to be good or evil. Let a man but transfer his judgements to matters that lie within the province of the moral purpose, and I guarantee that he will be steadfast, whatever be the state of things about him. ”

“ And so, therefore, when a man has an attack of vertigo, it is not the arts and the virtues that are thrown into confusion, but the spirit in which they exist; and when this grows steady again, so do they too. ”

“ After that is over we go out, and if we see a man in grief, we say, "It is all over with him"; if we see a Consul, we say, "Happy man"; if we see an exile, "Poor fellow"; or a poverty-stricken person, "Wretched man, he has nothing with which to get a bite to eat." These, then, are the vicious judgements which we ought to eradicate ”

“ It is chiefiy with this principle in mind that a man must exercise himself. Go out of the house at early dawn, and no matter whom you see or whom you hear, examine him and then answer as you would to a question. ”
