karl popper

Sir Karl Raimund Popper (28 July 1902 – 17 September 1994) was an Austrian–British philosopher, academic and social commentator. One of the 20th century's most influential philosophers of science, Popper is known for his rejection of the classical inductivist views on the scientific method in favour of empirical falsification. According to Popper, a theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can (and should) be scrutinised with decisive experiments. Popper was opposed to the classical justificationist account of knowledge, which he replaced with critical rationalism, namely "the first non-justificational philosophy of criticism in the history of philosophy".
In political discourse, he is known for his vigorous defence of liberal democracy and the principles of social criticism that he believed made a flourishing open society possible. Popper’s political thought would seem to fit most comfortably within the liberal camp, broadly understood. Reason, toleration, nonviolence and individual freedom formed the core of his political values, and he identified modern liberal democracies as the best-to-date embodiment of an open society. Popper himself acknowledged that his primary interest was nature and not politics.
