French
Une théorie qui n'est réfutable par aucun événement qui se puisse concevoir n'est pas scientifique. Pour les théories, l'irréfutabilité n'est pas (comme on l'imagine souvent) vertu mais défaut.

German
Eine Theorie, die durch kein denkbares Ereignis widerlegt werden kann, ist unwissenschaftlich. Unwiderlegbarkeit ist nicht, wie oft angenommen wird, eine Stärke einer Theorie, sondern eine Schwäche.

Karl Popper also said...


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





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.





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.





No rational argument will have a rational effect on a man who does not want to adopt a rational attitude.
