“Metaphor is the currency of knowledge. I have spent my life learning incredible amounts of disparate, disconnected, obscure, useless pieces of knowledge, and they have turned out to be, almost all of them, extremely useful.”

“Generally in life, knowledge is acquired to be used. But school learning more often fits Freire's apt metaphor: knowledge is treated like money, to be put away in a bank for the future.”

“I feel that all knowledge should be in the free-trade zone. Your knowledge, my knowledge, everybody's knowledge should be made use of. I think people who refuse to use other people's knowledge are making a big mistake. Those who refuse to share their knowledge with other people are making a great mistake, because we need it all. I don't have any problem about ideas I got from other people. If I find them useful, I'll just ease them right in and make them my own.”

“All knowledge is spendable currency, depending on the market.”

“This morning I looked at the books on my shelves and thought that they have no knowledge of my existence. They come to life because I open them and turn their pages, and yet they don't know that I am their reader.”

“It is better to fill your head with useless knowledge than no knowledge at all.”
