ASPECTS OF WALTON'S THEORY OF ARGUMENTATION SCHEMES

This paper seeks to further develop the study of argument schemes by focussing on some of the fundamental questions in scheme theory: the relationships between argument types (kinds), argument schemes, and arguments. It is proposed that we can distinguish schemes associated with argument types (generally) and schemes associated with normative types. This distinction has consequences for how we can use schemes for argument evaluation. I attempt to locate Doug Walton's impactful contributions to scheme theory by identifying the particular choices he made.
