Quote by Paul Feyerabend

"Science is not a collection of laws, a catalogue of unrelated items, but is an interpretation of nature."

"The only principle that does not inhibit progress is: anything goes."

"Knowledge is a human activity, and the most human of all."

"Facts are not independent of interpretation."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
