Quote by Popper, Karl

"The true paradox is only the paradox that is true."

"I may not be smarter than you, but I can admit when I'm wrong."

"The more we learn about the world, and the deeper our learning, the more conscious, clear and definite will be our knowledge of what we do not know."

"Science may be described as the art of systematic over-simplification."

"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."
