Man perfected by society is the best of all animals; he is the most terrible of all when he lives without law, and without justice.

It must not be supposed that happiness will demand many or great possessions; for self-sufficiency does not depend on excessive abundance, nor does moral conduct, and it is possible to perform noble deeds even without being ruler of land and sea: one can do virtuous acts with quite moderate resources. This may be clearly observed in experience: private citizens do not seem to be less but more given to doing virtuous actions than princes and potentates. It is sufficient then if moderate resources are forthcoming; for a life of virtuous activity will be essentially a happy life.

In the perfect state the good man is absolutely the same as the good citizen; whereas in other states the good citizen is only good relatively to his own form of government.

Virtue also depends on ourselves. And so also does vice. For where we are free to act we are also free to refrain from acting, and where we are able to say No we are also able to say Yes; if therefore we are responsible for doing a thing when to do it right, we are also responsible for not doing it when not to do it is wrong, and if we are responsible for rightly not doing a thing, we are also responsible for wrongly doing it.

Men acquire a particular quality by constantly acting in a particular way.

... the science we are after is not about mathematicals either none of them, you see, is separable.

For legislators make the citizens good by forming habits in them, and this is the wish of every legislator, and those who do not effect it miss their mark, and it is in this that a good constitution differs from a bad one.
