The advice of friends must be received with a judicious reserve; we must not give ourselves up to it and follow it blindly, whether right or wrong.

To owe an obligation to a worthy friend is a happiness, and can be no disparagement.

Gratitude is a duty none can be excused from, because it is always at our own disposal.

Pleasure and pain, though directly opposite, are yet so contrived by nature as to be constant companions; and it is a fact that the same motions and muscles of the face are employed both in laughing and crying.

Riches should be admitted into our houses, but not into our hearts; we may take them into our possession, but not into our affections.

Mutability is the badge of infirmity. It is seldom that a man continues to wish and design the same thing two days alike. Now he is for marrying; and now a mistress is preferred to a wife. Now he is ambitious and aspiring; presently the meanest servant is not more humble than he. This hour he squanders his money away; the next he turns miser. Sometimes he is frugal and serious; at other times profuse, airy, and gay.

Wise men mingle mirth with their cares, as a help either to forget or overcome them; but to resort to intoxication for the ease of one's mind is to cure melancholy by madness.
