Education and morals will be found almost the whole that goes to make a good man.

. . . the man is free, we say, who exists for his own sake and not for another's.

It is the mark of an educated mind to be able to entertain a thought without accepting it.

...happiness is an activity and a complete utilization of virtue, not conditionally but absolutely.

The ensouled is distinguished from the unsouled by its being alive. Now since being alive is spoken of in many ways, even if only one of these is present, we say that the thing is alive, if, for instance, there is intellect or perception or spatial movement and rest or indeed movement connected with nourishment and growth and decay. It is for this reason that all the plants are also held to be alive . . .

No excellent soul is exempt from a mixture of madness.

Since the branch of philosophy on which we are at present engaged differs from the others in not being a subject of merely intellectual interest — I mean we are not concerned to know what goodness essentially is, but how we are to become good men, for this alone gives the study its practical value — we must apply our minds to the solution of the problems of conduct.
