Who knows for what we live, and struggle, and die?... Wise men write many books, in words too hard to understand. But this, the purpose of our lives, the end of all our struggle, is beyond all human wisdom.
The wise find pleasure in water; the virtuous find pleasure in hills. The wise are active; the virtuous are tranquil. The wise are joyful; the virtuous are long-lived.
Academic chairs are many, but wise and noble teachers are few; lecture-rooms are numerous and large, but the number of young people who genuinely thirst after truth and justice is small
It is a wise thing to be polite; consequently, it is a stupid thing to be rude. To make enemies by unnecessary and willful incivility, is just as insane a proceeding as to set your house on fire. For politeness is like a counter--an avowedly false coin, with which it is foolish to be stingy.
When I want to think about what would be the right thing to do, the fair thing to do, the wise thing to do, I can just think of my grandmother. I can always hear her say, "Now sister, you know what's right. Just do right!"
There are three sorts of pleasures which are advantageous, and three which are injurious. Finding pleasure in the discriminating study of ceremonies and music, finding pleasure in discussing the good points in the conduct of others, and finding pleasure in having many wise friends, these are advantageous. But finding pleasure in profligate enjoyments, finding pleasure in idle gadding about, and finding pleasure in feasting, these are injurious.
