A man who examines each subject from a philosophical standpoint cannot neglect them: he has to omit nothing, and state the truth about each topic.

Since the whole city has one end, it is manifest that education should be one and the same for all, and that it should be public, and not private - not as at present, when every one looks after his own children separately, and gives them separate instruction of the sort which he thinks best; the training in things which are of common interest should be the same for all. Neither must we suppose that any one of the citizens belongs to himself, for they all belong to the state, and are each of them a part of the state, and the care of each part is inseparable from the care of the whole.

For through wondering human beings now and in the beginning have been led to philosophizing.

One citizen differs from another, but the salvation of the community is the common business of them all. This community is the constitution; the virtue of the citizen must therefore be relative to the constitution of which he is a member.

The virtue of the good man is necessarily the same as the virtue of the citizen of the perfect state.

Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit.

A goal gets us motivated,while a good habit keeps us stay motivated.
