If a man had begun to hate an object of his love, so that love is thoroughly destroyed, he will, causes being equal, regard it with more hatred than if he had never loved it, and his hatred will be in proportion to the strength of his former love.

Things which are accidentally the causes either of hope or fear are called good or evil omens.

I saw that all things I feared, and which feared me, had nothing good or bad in them save insofar as the mind was affected by them.

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.

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

Reason connot defeat emotion, an emotion can only be displaced or overcome by a stronger emotion.

Many errors, of a truth, consist merely in the application of the wrong names of things.
