All religions are inconsistent with mental freedom. Shakespeare is my bible, Burns my hymn-book.

In the presence of death I affirm and reaffirm the truth of all that I have said against the superstitions of the world. I would say that much on the subject with my last breath.

There may or may not be a Supreme Ruler of the universe-but we are certain that man exists, and we believe that freedom is the condition of progress; that it is the sunshine of the mental and moral world, and that without it man will go back to the den of savagery, and wll become the fit associate of wild and ferocious beasts.

Epithets are not arguments. Abuse does not persuade.

I would rather be a beggar and spend my money like a king, than be a king and spend money like a beggar.

When the will defies fear, when duty throws the gauntlet down to fate, when honor scorns to compromise with death - that is heroism.
