“There is no knowledge so hard to acquire as the knowledge of how to live this life well and naturally.”

“Real wisdom is not the knowledge of everything, but the knowledge of which things in life are necessary, which are less necessary, and which are completely unnecessary to know. Among the most necessary knowledge is the knowledge of how to live well, that is, how to produce the least possible evil and the greatest goodness in one’s life. At present, people study useless sciences, but forget to study this, the most important knowledge.”

“Learning isn't acquiring knowledge so much as it is trimming information that has already been acquired.”

“... a knowledge of how to live was a knowledge of how to die.”

“The only real science is the knowledge of how a person should live his life. And this knowledge is open to everyone.”

“How dangerous is the acquirement of knowledge and how much happier that man is who believes his native town to be the world, than he who aspires to be greater than his nature will allow.”
