Does another do me wrong? Let him look to it. He has his own disposition, his own activity. I now have what the universal nature wills me to have; and I do what my nature now wills me to do.
I consist of a little body and a soul. Now to this little body all things are indifferent, for it is not able to perceive differences. But to the understanding those things only are indifferent, which are not the works of its own activity. But whatever things are the works of its own activity, all these are in its power. And of these however only those which are done with reference to the present; for as to the future and the past activities of the mind, even these are for the present indifferent.
When thou wishest to delight thyself, think of the virtues of those who live with thee; for instance, the activity of one, and the modesty of another, and the liberality of a third, and some other good quality of a fourth. For nothing delights so much as the examples of the virtues, when they are exhibited in the morals of those who live with us and present themselves in abundance, as far as is possible. Wherefore we must keep them before us.
Where any work can be done conformably to the reason which is common to gods and men, there we have nothing to fear: for where we are able to get profit by means of the activity which is successful and proceeds according to our constitution, there no harm is to be suspected.
Not in passivity, but in activity lie the evil and the good of the rational social animal, just as his virtue and his vice lie not in passivity, but in activity.
Any one activity whatever it may be, when it has ceased at its proper time, suffers no evil because it has ceased; nor he who has done this act, does he suffer any evil for this reason that the act has ceased. In like manner then the whole which consists of all the acts, which is our life, if it cease at its proper time, suffers no evil for this reason that it has ceased; nor he who has terminated this series at the proper time, has he been ill dealt with.
