A few quotes:

[The Straight Story]

“The tax which will be paid for the purpose of education is not more than the thousandth part of what will be paid to kings, priests and nobles who will rise up among us if we leave the people in ignorance”

“There is only one good, knowledge, and one evil, ignorance”

“Ignorant people see life as either existence or non-existence, but wise men see it beyond both existence and non-existence to something that transcends them both; this is an observation of the Middle Way.”

“Discussion is an exchange of knowledge; an argument an exchange of ignorance.”
