There is in fact a true law namely right reason, which is in accordance with nature, applies to all men and is unchangeable and eternal. ... It will not lay down one rule at Rome and another at Athens, nor will it be one rule today and another tomorrow. But there will be one law eternal and unchangeable binding all times and upon all peoples.
No man can be brave who thinks pain the greatest evil; nor temperate, who considers pleasure the highest god.
[Lat., Fortis vero, dolorem summum malum judicans; aut temperans, voluptatem summum bonum statuens, esse certe nullo modo potest.]
Friendship makes prosperity brighter, while it lightens adversity by sharing its griefs and anxieties.
[Lat., Secundas res splendidiores facit amicitia, et adversas partiens communicansque leviores.]
Nihil est incertius vulgo, nihil obscurius voluntate hominum, nihil fallacius ratione tota comitiorum. (Nothing is more unpredictable than the mob, nothing more obscure than public opinion, nothing more deceptive than the whole political system.)
Nothing in oratory is more important than to win for the orator the favour of his hearer, and to have the latter so affected as to be swayed by something resembling an impulse of the spirit impetu quodam animi or emotion perturbatione, rather than by judgment or deliberation. For men decide far more problems by hate, or love, or lust, or rage, or sorrow, or joy, or hope, or fear, or illusion, or some other inward emotion aliqua permotione mentis, than by reality or authority, or any legal standard, or judicial precedent or statute.
