“Of course, science lives by confusing theories, but what were accepted as 'theories' even by the many professional psychologists and psychiatrists were very poor limitations of what physical scientists call a theory.”

Roy R. Grinker, Sr. (1900–1993) American psychiatrist and neurologist

If there be a third revolution (i.e. after the psychoanalytic and behavioristic), it is in the development of a general theory.

“The most beautiful fate of a physical theory is to point the way to the establishment of a more inclusive theory, in which it lives on as a limiting case.”

Albert Einstein (1879–1955) German-born physicist and founder of the theory of relativity

1910s

“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)

“The beginning of the twentieth century witnessed the breakdown of the mechanistic theory even within physics, the science where it was the most successful… Relativity took over in field physics, and the science of quantum theory in microphysics… In view of parallel developments in physics, chemistry, biology, sociology, and economics, many branches of the contemporary sciences became… ‘sciences of organized complexity’ — that is, systems sciences.”

Ervin László (1932) Hungarian musician and philosopher

“While the new physics was developing in the 20th century, the mechanistic Cartesian world view and the principles of Newtonian physics maintained their strong influence on Western scientific thinking, and even today many scientists still hold to the mechanistic paradigm, although physicists themselves have gone beyond it.
However, the new conception of the universe that has emerged from modern physics does not mean that Newtonian physics is wrong, or that quantum theory, or relativity theory, is right. Modern science has come to realize that all scientific theories are approximations to the true nature of reality; and that each theory is valid for a certain range of phenomena.”

“No fairer destiny could be allotted to any physical theory, than that it should of itself point out the way to the introduction of a more comprehensive theory, in which it lives on as a limiting case.”

Albert Einstein book Relativity: The Special and the General Theory

Es ist das schönste Los einer physikalischen Theorie, wenn sie selbst zur Aufstellung einer umfassenden Theorie den Weg weist, in welcher sie als Grenzfall weiterlebt.

“There were many Hayeks: Hayek, the political scientist; Hayek, the economist; Hayek, the philosopher of social science; Hayek, the psychologist. Even in these different roles, he played many parts.”
