Sympathy constitutes friendship but in love there is a sort of antipathy, or opposing passion. Each strives to be the other, and both together make up one whole.

Love, friendship and respect do not unite people as much as a common hatred for something.

In friendship as well as love, ignorance very often contributes more to our happiness than knowledge.

Opposition is true friendship.
