Aristotle, Nicomachean Ethics
H. Rackham, Ed.

the defect, in others the excess, is more opposed to the mean; for example Cowardice, which is a vice of deficiency, is more opposed to Courage than is Rashness which is a vice of excess; but Profligacy, or excess of feeling, is more opposed to Temperance than is Insensibility, or lack of feeling. [7] This results from either of two causes. One of these arises from the thing itself; owing to one extreme being nearer to the mean and resembling it more, we count not this but rather the contrary extreme as the opposite of the mean; for example, because Rashness seems to resemble Courage more than Cowardice does, and to be nearer to it, we reckon Cowardice rather than Rashness as the contrary of Courage; for those extremes which are more remote from the mean are thought to be more contrary to it. [8] This then is one cause, arising out of the thing itself. The other cause has its origin in us: those things appear more contrary to the mean to which we are ourselves more inclined by nature. For example, we are of ourselves more inclined to pleasure, which is why we are prone to Profligacy [more than to Propriety].¹ We therefore rather call those things the contrary of the mean, into which we are more inclined to lapse; and hence Profligacy, the excess, is more particularly the contrary of Temperance
