"There is more hope of a fool than of him." Which I take to mean that self-conceit is the rankest form of folly, a sort of triple armor of defence against counter-statement and rebutting argument.

So far as my experience goes to prove a disheartening proposition,--all fools are wise (to themselves) in their own conceit.

The first evidence of true wisdom is humility.

One may be ignorant without being foolish.

Lack of knowledge because the opportunity for acquiring it has been withheld, induces in the human mind such conditions as we find in a sponge that has been cleaned and dried.
