Quote by Feyerabend, Paul

"Science is an essentially anarchistic enterprise: theoretical anarchism is more humanitarian and more likely to encourage progress than its law-and-order alternatives."

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

"Knowledge so obtained is power, and power is always directed to some end that is of interest to the being that possesses it."

"A theory is accepted not because it has been proven correct but because it is useful."

"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."
