By playing at Chess then, we may learn: First: Foresight... Second: Circumspection... Third: Caution...And lastly, we learn by Chess the habit of not being discouraged by present bad appearances in the state of our affairs, the habit of hoping for a favorable chance, and that of persevering in the secrets of resources

Wise men learn by others' harms, fools scarcely by their own.

Virtue and Happiness are Mother and Daughter.

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.

None are deceived but they that confide.

As often as we do good, we sacrifice.

Be not disturbed at trifles, or at accidents common or unavoidable.
