This paper responds to a recent claim by Shrader-Frechette that current particle physics, with its essentially atomist paradigm, is in a state of Kuhnian crisis. We respond to Shrader-Frechette's claim in two ways: first, we argue directly against much of the evidence used by Shrader-Frechette as indicators of Kuhnian crisis; second, we question Shrader-Frechette's application of Kuhnian categories to current research in general, pointing out the dangers inherent in such an analysis.

Popper’s three world doctrine, it has been argued by Peyerahend and Krige, is a rejection of the type of critical dualism of facts and norms articulated in The Open Society. Peyerabend argues further that world 3 acts as a methodological prison designed to restrict the free decision of the individual theoretical scientist. It is my position that Popper's concept of world 3 is not a rejection of critical dualism but rather an attempt to allow for the existence of free normative (...) decisions within the context of a binding tradition. The key to understanding this move is the notion of an objective norm. Specifically I argue that Popper's pluralistic epistemology is based on a traditional many-levelled semantics developed originally to combat psychologism and used now to place the issue of the choice of methodological norms within the framework of a theory of tradition.
