Our minds are lazier than our bodies.

No man can love a second time the person whom he has once truly ceased to love.

Self-love is the love of a man's own self, and of everything else for his own sake. It makes people idolaters to themselves, and tyrants to all the world besides.

Perfect courage is to do without witnesses what one would be capable of doing with the world looking on.

Passion makes idiots of the cleverest men, and makes the biggest idiots clever.

We should often feel ashamed of our best actions if the world could see all the motives which produced them.

One kind of flirtation is to boast we never flirt.
