I honestly believe it iz better tew know nothing than tew know what ain't so.

Knowledge is folly, except grace guide it.

Knowledge is two-fold, and consists not only in an affirmation of what is true, but in the negation of that which is false.

Tis not knowing much, but what is useful, that makes a wise man.

Knowledge-that is, education in its true sense- is our best protection against unreasoning prejudice and panic-making fear, whether engendered by special interest, illiberal minorities, or panic-stricken leaders.

To know is not to be wise. To know how to use knowledge is to have wisdom.

Knowledge is the antidote to fear.

The public have an insatiable curiosity to know everything, except what is worth knowing.

The acquisition of knowledge always involves the revelation of ignorance-almost is the revelation of ignorance.

When you know a thing, to hold that you know it, and when you do not know a thing, to allow that you do not know it: this is knowledge.
