|Positivism, philosophy: modern positivism represents the demand to trace back statements with a claim to explanation to differences which can be ascertained in the objects of investigation. What is ascertainable is, in this case, relativized to a framework theory and its methods. This is intended to exclude foreign and non-verifiable statements. See also empiricism, internal/external, truth, provability.|
