History shows that there is nothing so easy to enslave and nothing so hard to emancipate as ignorance, hence it becomes the double enemy of civilization. By its servility it is the prey of tyranny, and by its credulity it is the foe of enlightenment.

And simple truth miscall’d simplicity,
And captive good attending captain ill.

I pity his ignorance and despise him.

Words are wise men’s counters, they do but reckon with them, but they are the money of fools.

All we know is still infinitely less than all that still remains unknown.
