[email protected] ABSTRACT: Perelman’s discussion about the distinction and relation between the rational and the reason- able could be seen as an attempt to bring forward a new understanding of rationality. In light of the concep- tion of situated reason, this paper argues that Perelman’s explication of the dialectic of the rational and the reasonable highlights the balance of universality and contexuality, and could contribute a fuller conception of rationality to establishing a solid philosophical foundation for Johnson’s informal logic. KEYWORDS: argumentation theory, Johnson, informal logic, Perelman, rationality, reasonableness, situ- ated reason.
