This article presents a critical analysis of the main modern approaches to the problem of meta-argumentation and suggests a method for developing a general conception of meta-argumentation. A set of theoretical-methodological difficulties (aporias) along this path is revealed. Overcoming these aporias would constitute the main steps toward developing the body of a theory of meta-argumentation.Keywords: argumentation, theory of argumentation, metatheory, metaargumentation, models of meta-argumentation, aporia, aporias of metaargumentation.The recent article by Hasmik Hovhannisyan in Metaphilosophy suggested an important clarification of the guidelines for the Rhodian and Platonic models of meta-argumentation, showed their areas of application, and conducted an analysis of contemporary conceptions of meta-argumentation (Hovhannisyan 2015). To further the development of a general theory of metaargumentation, in the present article we place the emphasis on the set of major difficult theoretical-methodological questions (aporias) encountered in the process of constructing a theory of meta-argumentation.One can point to three main interpretations of the term "metaargumentation" in the works of contemporary researchers:(1) Meta-argumentation as the study of models of a general theory of meta-argumentation (Brutian
