Inspirational Karl Popper Quotes

Karl Popper (28 July 1902 – 17 September 1994) was an Austrian-British philosopher and professor. This post features some Inspirational Karl Popper Quotes.

He is generally regarded as one of the greatest philosophers of science of the 20th century. Popper is known for his rejection of the classical inductivist views on the scientific method, in favour of empirical falsification: A theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can and should be scrutinized by decisive experiments.

― Karl Popper

“For myself, I am interested in science and in philosophy only because I want to learn something about the riddle of the world in which we live, and the riddle of man’s knowledge of that world. And I believe that only a revival of interest in these riddles can save the sciences and philosophy from an obscurantist faith in the expert’s special skill and in his personal knowledge and authority.”
Karl Popper quotes

“Philosophy is a necessary activity because we, all of us, take a great number of things for granted, and many of these assumptions are of a philosophical character; we act on them in private life, in politics, in our work, and in every other sphere of our lives — but while some of these assumptions are no doubt true, it is likely, that more are false and some are harmful. So the critical examination of our presuppositions — which is a philosophical activity — is morally as well as intellectually important.”
― Karl Popper

“In so far as a scientific statement speaks about reality, it must be falsifiable: and in so far as it is not falsifiable, it does not speak about reality.”
― Karl Popper
