Abstract

In the late forties and in the fifties, what was then known as the Oslo School of Philosophy, that is, Arne Naess and his students, received some fame, or notoriety, for its empirical investigations of lay uses of various epistemological terms, such as 'true', 'certain', 'probable'. It is less known that Arne Naess, in 1953, opened up a series of investigations into conceptual frameworks, the comparability of conceptual frameworks, and the senses, if any, in which a conceptual framework can be said to represent knowledge. In the course of these investigations Arne Naess, together with some of his students, developed views that are strikingly close to those of Ludwig Wittgenstein in ber Gewissheit. This paper examines some of those similarities and a few dissimilarities.
