"The children now love luxury. They have bad manners, contempt for authority; they show disrespect for elders and love chatter in place of exercise."

"The unexamined life is not worth living."

"I cannot teach anybody anything. I can only make them think"

"The only true wisdom is in knowing you know nothing."

"I only know that I know nothing"
