Karl Popper saw demarcation as a central problem in the philosophy of science. 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 'metaphysical' systems on the other, I call the problem of demarcation."

Popper's Philosophy of Science phenomena to be penetrated with their help, renders it inevitable that so much research effort - it will be 'theoretical' as well as experimen-tal - is spent in the manner described. And in general, the expec-tations we develop with the theory's help are, when observationally

It is an important historiographical contribution, particularly because it leads us to reevaluate our tradition of painting Kuhn as an epistemological radical, when that title more properly belongs to Popper. Karl Popper's philosophy of science uses modus tolens as the central method of disconfirming, or falsifying, scientific hypotheses. Scientists start with a current scientific theory and use the usual methods of deductive reasoning to derive specific conclusions, of which some are "predictions". Popper’s View of the Scientific Method. Popper’s method may be considered as an “anti-inductivist version of the hypothetico-deductive method” (Sankey 2010, 253). His model is based on two stages.

It is an important historiographical contribution, particularly because it leads us to reevaluate our tradition of painting Kuhn as an epistemological radical, when that title more properly belongs to Popper. To begin, Karl popper’s philosophical view of science is often referred to falsificationism, something to be proven false. This is shown through this example: If Socrates is a god, then Socrates is immortal. Socrates is not immortal. Therefore, Socrates is not a god.

Famously, Popper argued that science cannot verify theories but can only refute them, and this is how science makes progress.

Karl popper philosophy of science

Popper generalized his philosophy of science of falsificationism to arrive at a new conception of rationality – critical rationalism – the key methodological idea of Popper’s profound critical exploration of politi- cal and social issues in his The Open Society and Its Enemies(1966a) and The Poverty of Historicism(1961). Echoing the intellectual concerns of other philosophers, Sir Karl Popper was initially motivated to draw a line of demarcation between science and pseudo-science (Popper 2002, 344).

Karl Poppers philosophy of science has this modus tollens logic at its core. If a scientific hypothesis can have this logic applied then it is a science, if not it is a pseudo-science.

Karl Popper believed that scientific knowledge is provisional – the best we can do at the moment. Popper is known for his attempt to refute the classical positivist account of the scientific method, by replacing induction with the falsification principle. The Falsification Principle, proposed by Karl Popper, is a way of demarcating science from non-science. The Philosophy of Science of Karl Popper "It is the non-normal scientist, the daring, the critical scientist, who breaks through the barriers of normality, who opens the windows and lets in fresh air, who does not think about the impression he/she makes, but tries to be well understood." (Karl Popper in "Reason or Revolution?") Karl Popper's philosophy of science uses modus tolens as the central method of disconfirming, or falsifying, scientific hypotheses.

He made significant contributions to debates concerning general scientific methodology and theory choice, the demarcation of science from non-science, the nature of probability and quantum mechanics, and the methodology of the social sciences. The Falsification Principle, proposed by Karl Popper, is a way of demarcating science from non-science. It suggests that for a theory to be considered scientific it must be able to be tested and conceivably proven false.
