Courage is a mean Between cowardice and rashness; liberality, between prodigality and meanness; proper pride, between vanity and humility; ready wit, between buffoonery and boorishness; modesty, between bashfulness and shamelessness.

Context

“That aptly is put on.
We now come to the famous doctrine of the golden mean. Every virtue is a mean between two extremes, each of which is a vice. This is proved by an examination of the various virtues. Courage is a mean Between cowardice and rashness; liberality, between prodigality and meanness; proper pride, between vanity and humility; ready wit, between buffoonery and boorishness; modesty, between bashfulness and shamelessness. Some virtues do not seem to fit into this scheme; for instance, truthfulness. Aristotle says that this is a mean between boastfulness and mock-modesty (1108a) , but this only applies to truthfulness about oneself.” source
