If any man seeks for greatness, let him forget greatness and ask for truth, and he will find both.

Great knowledge is requisite to instruct those who have been well instructed, but still greater knowledge is requisite to instruct those who have been neglected.

So, in the infinitely nobler battle in which you are engaged against error and wrong, if ever repulsed or stricken down, may you always be solaced and cheered by the exulting cry of triumph over some abuse in Church or State, some vice or folly in society, some false opinion or cruelty or guilt which you have overcome! And I beseech you to treasure up in your hearts these my parting words: Be ashamed to die until you have won some victory for humanity.

Do not think of knocking out another person's brains because he differs in opinion from you. It would be as rational to knock yourself on the head because you differ from yourself ten years ago.

There is a deeper pleasure in following truth to the scaffold or the cross, than in joining the multitudinous retinue, and mingling our shouts with theirs, when victorious error celebrates its triumphs.
