Crassum videbamus. Quo in genere versutissimum et patientissimum Lacedaemonium Lysandrum accepimus, contraque Callicratidam, qui praefectus classis proximus post Lysandrum fuit; itemque in sermonibus alium [quemque], quamvis[100] praepotens sit, efficere, ut unus de multis esse videatur; quod in Catulo, et in patre et in filio, itemque in Q. Mucio† Mancia[101] vidimus. Audivi ex maioribus natu hoc idem fuisse in P. Scipione Nasica, contraque patrem eius, illum qui Ti. Gracchi conatus perditos vindicavit, nullam comitatem habuisse sermonis [ne Xenocratem quidem, severissimum philosophorum,][102] ob eamque rem ipsam magnum et clarum fuisse. Innumerabiles aliae dissimilitudines sunt naturae morumque, minime tamen vituperandorum. [97] _volumus_ A B^1 H^1 b; _volemus_ B^2 H^2, Bt., Heine; _velimus_ L; _vellemus_ c.

But it is essential to every inquiry about duty that we keep before our eyes how far superior man is by nature to cattle and other beasts: they have no thought except for sensual pleasure and this they are impelled by every instinct to seek; but man's mind is nurtured by study and meditation; he is always either investigating or doing, and he is captivated by the pleasure of seeing and hearing. #(4) pleasure.# Nay, even if a man is more than ordinarily inclined to sensual pleasures, provided, of course, that he be not quite on a level with the beasts of the field (for some people are men only in name, not in fact)--if, I say, he is a little too susceptible to the attractions of pleasure, he hides the fact, however much he may be caught in its toils, and for very shame conceals his appetite.
