"To lack intelligence is to be in the ring blindfolded."

Shake off all the fears and servile prejudices under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a god; because, if there be one, he must more approve the homage of reason, than that of blindfolded fear... Your own reason is the only oracle given you by heaven, and you are answerable not for the rightness but uprightness of the decision.

— Thomas Jefferson
