Robert Louis Stevenson on Philosophy

"All human beings, as we meet them, are commingled out of good and evil."

"There is no duty we so much underrate as the duty of being happy."

"When things fall out opportunely for the person concerned, he is not apt to be critical about the how or why, his own immediate personal convenience seeming a sufficient reason for the strangest oddities and revolutions in our sublunary things."

"Falling in love is the one illogical adventure, the one thing of which we are tempted to think as supernatural, in our trite and reasonable world. The effect is out of all proportion with the cause. Two persons, neither of them, it may be, very amiable or very beautiful, meet, speak a little, and look a little into each other's eyes. That has been done a dozen or so of times in the experience of either with no great result. But on this occasion all is different. They fall at once into that state in which another person becomes to us the very gist and centrepoint of God's creation, and demolishes our laborious theories with a smile; in which our ideas are so bound up with the one master-thought that even the trivial cares of our own person become so many acts of devotion, and the love of life itself is translated into a wish to remain in the same world with so precious and desirable a fellow-creature."

"For there is a fellowship more quiet even than solitude, and which, rightly understood, is solitude made perfect."
