Abstract

This paper aims to discuss the philosophical roles of common sense in Thomas Reid’s thought. I argue that there is not only one way of appealing to common sense in attempt of discovering truth and allowing knowledge. According to my understanding, Reid makes at least three distinct uses of common sense: (1) the foundational use, in which common sense is taken as the foundation upon which knowledge must be built; (2) the methodological use, in which common sense arises as a source of methodo-logical presuppositions of philosophical investigations; (3) the instrumental use, in which common sense, in the light of the emotion of ridicule, is used as an instrument to refute philosophical principles and conclusions.
