Falsifiability (or refutability) is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the philosopher of science Karl Popper in his book The Logic of Scientific Discovery (1934). [B] A theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test.
The philosopher Paul Ricœur endorsed "procedures of invalidation" similar to Popper's criteria for falsifiability. [6] The historian Peter Gay described the work as "an important treatise in epistemology". [7] The philosopher Bryan Magee considered Popper's criticisms of logical positivism "devastating".

[ 6 ] [ 7 ] [ 8 ] One of the 20th century's most influential philosophers of science , [ 9 ] [ 10 ] [ 11 ] Popper is known for his rejection of the classical inductivist views on the scientific ...
Karl Popper considered demarcation as a major problem of the philosophy of science. Popper articulates the problem of demarcation as: Popper articulates the problem of demarcation as: The problem of finding a criterion which would enable us to distinguish between the empirical sciences on the one hand, and mathematics and logic as well as ...
The founder of critical rationalism: Karl Popper. In the mid-twentieth century, several important philosophers began to critique the foundations of logical positivism.In his work The Logic of Scientific Discovery (1934), Karl Popper, the founder of critical rationalism, argued that scientific knowledge grows from falsifying conjectures rather than any inductive principle and that ...
This led Popper to his falsifiability criterion. Popper wrote about critical rationalism in many works, including: The Logic of Scientific Discovery (1934/1959), [ 1 ] The Open Society and Its Enemies (1945), [ 2 ] Conjectures and Refutations (1963), [ 3 ] Unended Quest (1976), [ 4 ] and The Myth of the Framework (1994).
Karl Popper argues that a preference for simple theories need not appeal to practical or aesthetic considerations. Our preference for simplicity may be justified by its falsifiability criterion: we prefer simpler theories to more complex ones "because their empirical content is greater; and because they are better testable". [39]
In Popper's philosophy of science, scientific statements are always provisional, they have limits of application, and they could always be wrong. If a statement cannot even in principle be proved wrong, it cannot be a scientific statement. Thus, in Popper's eyes, the falsifiability criterion clearly demarcates "science" from "non-science". This ...
