The Informal Core of Formal Logic

Abstract

In this chapter I want to carry on with issues raised in its predecessor. The position that I take here is that if informal logic can lay claim to a coherent research programme it is incumbent on its practitioners to display the programme concretely. In the preceding chapter I argued that a degree of formality is needed for informal logic. In the present chapter I return the compliment, claiming that informality is an irreducible part of formal logic.
