All credibility, all good conscience, all evidence of truth come only from the senses.

The truth will set you free, but first it will make you miserable.

I believe that it is better to tell the truth than a lie. I believe it is better to be free than to be a slave. And I believe it is better to know than to be ignorant.

Experience has shown, and a true philosophy will always show, that a vast, perhaps the larger portion of the truth arises from the seemingly irrelevant.

Stand upright, speak thy thoughts, declare The truth thou hast, that all may share Be bold, proclaim it everywhere: They only live who dare.
