What men have called friendship is only a social arrangement, a mutual adjustment of interests, an interchange of services given and received it is, in sum, simply a business from which those involved propose to derive a steady profit for their own self-love.
Passion makes idiots of the cleverest men, and makes the biggest idiots clever.
We always love those who admire us, but we do not always love those whom we admire.
We are nearer loving those who hate us than those who love us more than we wish.
We may sooner be brought to love them that hate us, than them that love us more than we would have them do.
Love can no more continue without a constant motion than fire can and when once you take hope and fear away, you take from it its very life and being.
It is with true love as it is with ghosts everyone talks about it, but few have seen it.
In friendship as well as love, ignorance very often contributes more to our happiness than knowledge.
