If you would not be known to do anything, never do it.

Stand guard at the portal of your mind.

To different minds, the same world is a hell, and a heaven.

If a man knew anything, he would sit in a corner and be modest; but he is such an ignorant peacock, that he goes bustling up and down, and hits on extraordinary discoveries.

Knowledge is the antidote to fear

Heaven often protects valuable souls charged with great secrets, great ideas, by long shutting them up with their own thoughts.

It is long ere we discover how rich we are. Our history, we are sure, is quite tame: we have nothing to write, nothing to infer. But our wiser years still run back to the despised recollections of childhood. . . .
