A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.
Karl Popper - Conjectures and Refutations: The Growth of Scientific Knowledge / 





Our knowledge can only be finite, while our ignorance must necessarily be infinite.
Karl Popper / 





Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.
Karl Popper / 





The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities—perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there.
Karl Popper





We must plan for freedom, and not only for security, if for no other reason than that only freedom can make security secure.
Karl Popper





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