All authority is in the throne; and what is the throne? This wooden frame covered with velvet? No, I am the throne.

If you find from your own experience that something is a fact and it contradicts what some authority has written down, then you must abandon the authority and base your reasoning on your own findings.

Whoever in discussion adduces authority uses not intellect but rather memory.

Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory.

I firmly believe that the army of persons who urge greater and greater centralization of authority and greater and greater dependence upon the Federal Treasury are really more dangerous to our form of government than any external threat that can possibly be arrayed against us.

Nothing strengthens authority so much as silence.
