Nature in denying us perennial youth has at least invited us to become unselfish and noble.

The more rational an institution is the less it suffers by making concessions to others.

Trust the man who hesitates in his speech and is quick and steady in action, but beware of long arguments and long beards.

It would be hard to conceive a system of instincts more nicely adjusted, where the constituents should represent or support one another better. The husband has an interest in protecting the wife, she in serving the husband. The weaker gains in authority and safety, the wilder and more unconcerned finds a help-mate at home to take thought of his daily necessities. Parents lend children their experience and a vicarious memory; children endow their parents with a vicarious immortality.

... so in love the heart surrenders itself entirely to the one being that has known how to touch it. That being is not selected; it is recognised and obeyed.

One real world is enough.

Sex endows the individual with a dumb and powerful instinct, which carries his body and soul continually towards another, makes it one of the dearest employments of his life to select and pursue a companion, and joins to possession the keenest pleasure, to rivalry the fiercest rage, and to solicitude an eternal melancholy. What more could be needed to suffuse the world with the deepest meaning and beauty?
