they follow nature as the most perfect guide to a good life. - Cicero

While there are two ways of contending, one by discussion, the other by force, the former belonging properly to man, the latter to beasts, recourse must be had to the latter if there be no opportunity for employing the former.

Omnium autem rerum, ex quibus aliquid adquiritur, nihil est agri cultura melius, nihil uberius, nihil dulcius, nihil homine libero dignius.

The mind becomes accustomed to things by the habitual sight of them, and neither wonders nor inquires about the reasons for things it sees all the time.
