He who receives a benefit should never forget it; he who bestows should never remember it.

Pleasure and pain, though directly opposite are contrived to be constant companions.

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.

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

God, Nature, the wise, the world, preach man, exhort him both by word and deed to the study of himself.

He who receives a benefit should never forget it; he who bestows should never remember it.

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.
