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 ...
The philosopher Bryan Magee considered Popper's criticisms of logical positivism "devastating". In his view, Popper's most important argument against logical positivism is that, while it claimed to be a scientific theory of the world, its central tenet, the verification principle, effectively destroyed all of science.

The theory met critical objections to truth as correspondence and thereby rehabilitated it. The theory also seemed, in Popper's eyes, to support metaphysical realism and the regulative idea of a search for truth. According to this theory, the conditions for the truth of a sentence as well as the sentences themselves are part of a metalanguage ...
The apparent contradiction seen in the case of a true but falsifiable statement disappears once we know the technical definition. Falsifiability differs from verifiability, which was held as fundamental by many philosophers such as those of the Vienna Circle. In order to verify the claim "All swans are white" one would have to observe every ...
In philosophy of science and epistemology, the demarcation problem is the question of how to distinguish between science and non-science. [1] It also examines the boundaries between science, pseudoscience and other products of human activity, like art and literature and beliefs.
They are either falsifiable and thus empirical (in a very broad sense), or not falsifiable and thus non-empirical. Those claims to knowledge that are potentially falsifiable can then be admitted to the body of empirical science, and then further differentiated according to whether they are retained or are later actually falsified.
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".
