In 'The Empirical Stance' Bas C. van Fraassen sets out to uncover the spirit of empiricism: “what is empiricism, and what it could be, if it is to be a viable philosophy today?” (2002, p. 31). In answer to this question van Fraassen rejects the canonical characterization of empiricism as a philosophical position established on a thesis (such as all knowledge comes from sense experience), and argues that we must endorse empiricism as a philosophical position established in a stance. But what the empirical stance is or entails exactly, van Fraassen has failed to make clear. The purpose of this thesis is to analyze and philosophically evaluate empiricism as a stance. In light of my analysis, however, I will argue that van Fraassen has not provided a concrete characterization of stance empiricism (or indeed stances in general), and that the concept remains problematically vague.
