I believe there exists, & I feel within me, an instinct for the truth, or knowledge or discovery, of something of the same nature as the instinct of virtue, & that our having such an instinct is reason enough for scientific researches without any practical results ever ensuing from them.

Death is at any time blessed but it is twice blessed for a warrior who dies for his cause, that is, truth.

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.

Even if you are a minority of one, the truth is the truth.

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

A man of truth must ever be confident, if he has also equal need to be diffident.
