"The learning and knowledge that we have, is, at the most, but little compared with that of which we are ignorant."

"No tools will make a man a skilled workmen, or master of defense, or be of any use to him who has not learned how to handle them and has never bestowed any attention on them."

"No man should bring children into world who is unwilling to persevere to the end in their nature and education."

"Does not every man love that which he deems noble and just and good, and hate the opposite of them? people regard the same things, some as just and others as unjust, about these they dispute; and so there arise wars and fightings among them."

"If a man neglects education, he walks lame to the end of his life."
