Friedrich Wilhelm Nietzsche (弗里德里希·威廉·尼采):

Reading history makes people wise, poetry witty, mathematics thoughtful, science profound, ethics solemn, logic and rhetoric makes people eloquent.

读史使人明智,读诗使人灵秀,数学使人周密,科学使人深刻,伦理学使人庄重,逻辑修辞之学使人善辩;凡有所学,皆成性格。

Aristotle (亚里士多德):

I have learned this through philosophy: I act out of self-consciousness, others act only because of fear of the law.

我通过哲学了解了这一点:我行事是出于自觉,他人行事只是因为害怕法律。
