To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further.

That is what I am, and who can dispute it in the years of life that still remain for me?

Because people have no thoughts to deal in, they deal cards, and try and win one another’s money. Idiots!

The heavy armor becomes the light dress of childhood; the pain is brief, the joy unending.
