“The Steady State theory was what Karl Popper would call a good scientific theory: it made definite predictions, which could be tested by observation, and possibly falsified. Unfortunately for the theory, they were falsified.”

Stephen Hawking (1942–2018) British theoretical physicist, cosmologist, and author

The Beginning of Time (1996)

“An open society such as ours is based on the recognition that our understanding of reality is inherently imperfect. Nobody is in possession of the ultimate truth. As the philosopher Karl Popper has shown, the ultimate truth is not attainable even in science. All theories are subject to testing and the process of replacing old theories with better ones never ends.”

George Soros (1930) Hungarian-American business magnate, investor, and philanthropist

Speech at the National Press Club (2004)

“According to the most influential twentieth-century philosopher of science, Karl Popper, a theory is scientific only in so far as it is falsifiable, and should be given up as soon as it has been falsified. By this standard, the theories of Darwin and Einstein should never have been accepted.”

“What the founders of modern science … had to do, was not criticize and to combat certain faulty theories, and to correct or to replace them by better ones. They had to do something quite different. They had to destroy one world and replace it by another.”

Alexandre Koyré (1892–1964) French philosopher

"Galileo to Plato" in the Journal of the History of Ideas (1957).
Context: What the founders of modern science … had to do, was not criticize and to combat certain faulty theories, and to correct or to replace them by better ones. They had to do something quite different. They had to destroy one world and replace it by another. They had to reshape the framework of our intellect itself, to restate and to reform its concepts, to evolve a new approach to Being, a new concept of knowledge, and a new concept of science — and even to replace a pretty natural approach, that of common sense, by another which is not natural at all.

“(a) There is a general tendency towards integration in the various sciences, natural and social. (b) Such integration seems to be centered in a general theory of systems. (c) Such theory may be an important means of aiming at exact theory in the nonphysical fields of science. (d) Developing unifying principles running "vertically" through the universe of the individual sciences, this theory brings us nearer to the goal of the unity of sciences. (e) This can lead to a much needed integration in scientific education.”

Ludwig von Bertalanffy (1901–1972) austrian biologist and philosopher

Variant: Mayor aims of general theory: (1) There is a general tendency toward integration in the various sciences, natural and social. (2) Such integration seems to be centered in a general theory of systems. (3) Such theory may be an important means for aiming at exact theory in the nonphysical fields of science. (4) Developing unifying principles running "vertically" through the universe of the individual sciences, this theory brings us nearer the goal of the unity of science. (5) This can lead to a much-needed integration in scientific education.

“Until creationists accept that their claims must be falsifiable and show how they could be falsified, creationism cannot be said to be a scientific theory.”

“Science, especially evolutionary sciences, can only proceed from learning about theories of hypotheses that do not stand the test of time.”

Jeffrey H. Schwartz (1948) American anthropologist

Preface
What the Bones Tell Us (1997)

“The greater the number of conjectured theories that are confronted by the realities of the world, and the more speculative those conjectures are, the greater will be the chances of major advances in science.”
