This critical appraisal of Juan Comesaña’s Being Rational and Being Right is divided into three sections: Section I describes the fundamental features of “Experientialism,” the theory of basic rationality developed and defended in the book; Section II briefly indicates how the chapters of the book unfold; and Section III describes and examines one problematic issue concerning how Experientialism interacts with the liberalism/conservatism debate in the theory of justification.
