§81.1Fr. 81
Οὐκ, εἰ δή που τοῦτο τῷ γένει τιμώτερον, ἤδη καὶ, ὁτιοῦν ἂν ᾖ μέρος τούτου, πρὸς τὸ τηλίκον θατέρου συγκρινόμενον, αἱρετὸν ἔσται.
It is not the case that, if indeed this thing is more valuable by kind, immediately also whatever part of it there may be, when compared to a certain size of the other, will be more desirable.
Λέγω δὲ οἷον, οὐ καὶ χρυσίον τιμιώτερον χαλκοῦ καὶ τηλίκον τοῦ χρυσίου πρὸς τὸ τηλίκον χαλκοῦ μέγεθος ἀντιπαραβαλλόμενον πλέον δόξει;
I mean, for example: is not gold also more valuable than bronze? And will a gold piece of such a size, when compared to a bronze mass of such a size, seem to be more?
ἀλλὰ ποιήσει τινὰ ῥοπὴν καὶ τὸ πλῆθος καὶ τὸ μέγεθος.
Rather, both quantity and size will carry some weight.
