Once the people begin to reason, all is lost

"I can't" isn't a reason to give up, it's a reason to try harder

Many are destined to reason wrongly; others, not to reason at all; and others, to persecute those who do reason.

Faith consists in believing what reason cannot.

What is madness? To have erroneous perceptions and to reason correctly from them

Prejudices are what fools use for reason.
