One can tell a child everything, anything. I have often been struck by the fact that parents know their children so little. They should not conceal so much from them. How well even little children understand that their parents conceal things from them, because they consider them too young to understand! Children are capable of giving advice in the most important matters.

Every man looks out for himself, and he has the happiest life who manages to hoodwink himself best of all.

I've always considered myself smarter than everyone around me, and sometimes, believe me, I've been ashamed of it. At the least, all my life I've looked away and never could look people straight in the eye.

There is no virtue if there is no immortality.

...a condemned man who, at the hour of death, says or thinks that if the alternative were offered him of existing somewhere, on a height of rock or some narrow elevation, where only his two feet could stand, and round about him the ocean, perpetual gloom, perpetual solitude, perpetual storm, to remain there standing on a yard of surface for a lifetime, a thousand years, eternity! - rather would he live thus than die at once? Only live, live, live! - no matter how, only live!

The more I love humanity in general, the less I love man in particular.

To achieve perfection, one must first begin by not understanding many things! And if we understand too quickly, we may not understand well.
