Abstract
This article explores manner by which Karl Popper sees relation between scientific method and democracy. This connection is one of the foundations of Popper's thought.
For adequate understanding it is necessery to put Popper in historical context within developement of liberal thought and show possible links between his and Schumpeter's redefinition of democracy. Main point, however, is interpretation of basic Popper's epistemological presumptions - concept of temporality of scientific knowledge and ratio negativa.
Primary aim of the article is contextualization of these presumptions with their sociological a politological consequenses. Those can be seen not only in Popper's refusal of positivism and esentialism, but also if his preference of electoral and party systems.
At the end, concepts of critical rationalism, values and open society si elaborated according to possible objections to Popper's theory.
