This is untranslateable. As the Greek phrase, [Greek: echein logon tinos], really denotes substituting that person’s [Greek: logos] for one’s own, so the Irrational nature in a man of self-control or perfected self-mastery substitutes the orders of Reason for its own impulses. The other phrase means the actual possession of mathematical truths as part of the mental furniture, i.e. knowing them.

[Greek: xin] may be taken as opposed to [Greek: energeian], and the meaning will be, to show a difference between Moral and Intellectual Excellences, that men are commended for merely having the latter, but only for exerting and using the former.

Which we call simply virtue.

For nature must of course supply the capacity.
