What everyone wants from life is continuous and genuine happiness.

When a man is prey to his emotions, he is not his own master.

Men who are ruled by reason desire nothing for themselves which they would not wish for all mankind.

He whose honor depends on the opinion of the mob must day by day strive with the greatest anxiety, act and scheme in order to retain his reputation. For the mob is varied and inconsistent, and therefore if a reputation is not carefully preserved it dies quickly.

Emotion, which is suffering, ceases to be suffering as soon as we form a clear and precise picture of it.

From what has been said we can clearly understand the nature of Love and Hate. Love is nothing else but pleasure accompanied by the idea of an external cause: Hate is nothing else but pain accompanied by the idea of an external cause. We further see, that he who loves necessarily endeavors to have, and to keep present to him, the object of his love; while he who hates endeavors to remove and destroy the object of his hatred.

A man is as much affected pleasurably or painfully by the image of a thing past or future as by the image of a thing present.
