[13] If the mina be taken at 15 oz. avoirdupois, (Dict. of G. and R. Antiquities, article _Talentum_,) we must be sadly degenerate in our gastric capacity. [14] The two are necessary, because since the reason itself may be perverted, a man must have recourse to an external standard; we may suppose his [Greek: logos] originally to have been a sufficient guide, but when he has injured his moral perceptions in any degree, he must go out of himself for direction. [15] This is one of the many expressions which seem to imply that this treatise is rather a collection of notes of a _vivâ voce_ lecture than a set formal treatise. “The table” of virtues and vices probably was sketched out and exhibited to the audience. [16] Afterwards defined as “All things whose value is measured by money.” [17] We have no term exactly equivalent; it may be illustrated by Horace’s use of the term _hiatus_: “Quid dignum tanto feret hic promissor hiatu?” Opening the mouth wide gives a promise of something great to come, if nothing great does come, this is a case of [Greek: chaunotes] or fruitless and unmeaning _hiatus_; the transference to the present subject is easy. [18] In like manner _we_ talk of laudable ambition, implying of course there may be that which is not laudable. [19] An expression of Bishop Butler’s, which corresponds exactly to the definition of [Greek: nemesis] in the Rhetoric. [20] That is, in the same genus; to be contraries, things must be generically connected: [Greek: ta pleiston allelon diestekota ton en to auto genei enantia orizontai]. Categories, iv. 15. [21] “[Greek: Deuteros plous] is a proverb,” says the Scholiast on the Phaedo, “used of those who do anything safely and cautiously inasmuch as they who have miscarried in their first voyage, set about then: preparations for the second cautiously,” and he then alludes to this passage. [22] That is, you must allow for the _recoil_. “Naturam expellas furca tamen usque recurret.” P. 43, l. 2. This illustration sets in so clear a light the doctrines entertained respectively by Aristotle, Eudoxus, and the Stoics regarding pleasure, that it is worth while to go into it fully. The reference is to Iliad iii. 154-160. The old counsellors, as Helen comes upon the city wall, acknowledge her surpassing beauty, and have no difficulty in understanding how both nations should have incurred such suffering for her sake still, fair as she is, home she must go, that she bring not ruin on themselves and their posterity. This exactly represents Aristotle’s relation to Pleasure he does not, with Eudoxus and his followers, exalt it into the Summum Bonum (as Paris would risk all for Helen), nor does he the the Stoics call it wholly evil, as Hector might have said that the woes Helen had caused had “banished all the beauty from her cheek,” but, with the aged counsellors, admits its charms, but aware of their dangerousness resolves to deny himself, he “feels her sweetness, yet defies her thrall.”
