A vulgar man is captious and jealous; eager and impetuous about trifles. He suspects himself to be slighted, and thinks everything that is said meant at him.

One should always think of what one is about; when one is learning one should not think of play; and when one is at play, one should not think of one's learning.

The manner of a vulgar man has freedom without ease, and the manner of a gentleman has ease without freedom.

Loud laughter is the mirth of the mob, who are only pleased with silly things; for true wit or good sense never excited a laugh since the creation of the world. A man of party and fashion, therefore, is only seen to smile, but never heard to laugh.

A weak mind is like a horoscope, which magnifies trifling things but cannot receive great ones.

The vulgar only laugh, but never smile; whereas well-bred people often smile, but seldom laugh.

Knowledge may give weight, but accomplishments give lustre, and many more people see than weigh.

Maintain a clean and strong character.

Knowledge of the world is only to be acquired in the world, and not in the closet.

If you can engage people's pride, love, pity, ambition (or whatever is their prevailing passion) on your side, you need not fear what their reason can do against you.
