With regard to anger, the mean is good temper, and the extremes are irascibility and inirascibility. The mean between boastfulness and self-depreciation is truth. The mean between buffoonery and boorishness is wit. The mean between complaisance or flattery and quarrelsomeness is friendliness. A sense of shame is not a virtue.
Righteous indignation is a mean between envy and malicious gladness.
The person at either extreme of vice thinks that the virtuous person is at an extreme. A rash man, for example, thinks a brave man is a coward. Of the two vices on either extreme of virtue, one of them is more directly opposed to the virtue, while the other is merely a deficiency or excess. For example, cowardice is actually opposed to bravery, while rashness is an excess of bravery. A person aiming at the mean should avoid the vice which is more directly contrary to the mean, and also take into account the vices to which we are more inclined.
