Abstract

On September 17, 1994, Karl Popper died at the age of 92.He was described as the official opposition of the “ Vienna Circle”, the philosophical club which in the inter-war period was glamorous and which espoused the then popular doctrine of logical positivism, so-called. His relations with that club were friendly-hostile, to use the term with which he liked to characterize the relations between scientific researchers. He is the last of that generation (unless it is Carl G. Hempel, who, however, sees himself as too young to belong there). The public aspect of Popper’s friendly-hostile relations with his Viennese peers was unfortunately more hostile than friendly. Somehow, philosophers have managed to keep the accounts open for too long. The end of the era is the time to close accounts so as to be able to go on with the job at hand, since the intermingling of personal affairs with objective knowledge is unhealthy. Yet most of the leading heirs of the “ Vienna Circle” still coast around the issues raised by Popper, and so they can neither overlook him nor quote him correctly. If past evidence is reliable here, then this will alter just about now. Is it?
