Persisting in a charge which one does not know to be true, is simply malicious slander.

I planted myself upon the truth, and the truth only, so far as I knew it, or could be brought to know it.

In this sad world of ours, sorrow comes to all; and, to the young, it comes with bitterest agony, because it takes them unawares.

Many people, especially ignorant people, want to punish you for speaking the truth, for being correct, for being you. Never apologize for being correct, or for being years ahead of your time. If you're right and you know it, speak your mind. Speak your mind. Even if you are a minority of one, the truth is still the truth.

Debates conceal rather than reveal the truth. Truth is revealed in solitude.

Truth is as hard as adamant and tender as a blossom.
