I only study the things I like; I apply my mind only to matters that interest me. They'll be useful-or useless-to me or to others in due course, I'll be given-or not given-the opportunity of benefiting from what I've learned. In any case, I'll have enjoyed the inestimable advantage of doing things I like doing and following my own inclinations.

Thought consoles us for all, and heals all. If at times it does you ill, ask it for the remedy for that ill and it will give it to you.

Knowledge is boundless,--human capacity, limited.

Most benefactors are like unskillful generals who take the city and leave the citadel intact.

Women of the world crave excitement.

Marriage follows on love as smoke on flame.

Whoever is not a misanthrope at forty can never have loved mankind.
