The rapid progress of the sciences makes me sorry, at times, that I was born so soon. Imagine the power that man will have over matter, a few hundred years from now. We may learn how to remove gravity from large masses, and float them over great distances. Agriculture will double its produce with less labor. All diseases will surely be cured... even old age. If only the moral sciences could be improved as well. Perhaps men would cease to be wolves to one another... and human beings could learn to be human.

... there is much truth in the Italian saying, 'Make yourselves sheep, and the wolves will eat you.'

Since thou are not sure of a minute, throw not away an hour.

Virtue and Happiness are Mother and Daughter.

Who is strong? He that can conquer his bad habits.

Leisure is the time for doing something useful. This leisure the diligent person will obtain the lazy one never.

If passion drives you, let reason hold the reins.
