Rationality, Reason and the History of Thought

Philosophers over the course of the last century, including Edmund Husserl, Chaim Perelman, and Jacques Derrida, have attempted to unravel the tangled relationship between the rational and the reasonable in order to understand how the history of thought progresses. Critical political theorists, including Michel Foucault and Ernesto Laclau have also investigated this issue from a range of perspectives, especially as it relates to the relationship between ideational limits and their transgression and the universal and the particular. This essay compares these perspectives to locate the rational dimensions of the reasonable, and to relate that “meta-reason” to the irrational and unreasonable aspects of identity formation and the unfolding of world history.
