Karl Popper Quotes: 6

  • Science may be described as the art of systematic oversimplification.

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

  • 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.

  • No book can ever be finished. While working on it we learn just enough to find it immature the moment we turn away from it

  • While differing widely in the various little bits we know, in our infinite ignorance we are all equal.

  • The more we learn about the world, and the deeper our learning, the more conscious, specific, and articulate will be our knowledge of what we do not know; our knowledge of our ignorance. For this indeed, is the main source of our ignorance - the fact that our knowledge can be only finite, while our ignorance must necessarily be infinite.
