Scientific Discovery: That-Whats and What-Thats

Abstract

In this paper I defend Kuhn’s view of scientific discovery, which involves two central tenets, namely (i) that a scientific discovery always requires a discovery-that (i.e., the observation of X) and a discovery-what (i.e., the correct conceptualisation of X); and (ii) that there are two kinds of scientific discovery, resulting from the temporal order of the discovery-that and the discovery-what. I identify two problems with Kuhn’s ac- count and offer solutions to them from a realist stance. I also discuss alternatives to Kuhn’s account.
