Does theorising always presuppose a programme of justification? Does the Critical Theory of Adorno and Horkheimer do so? Do they claim it does? The answer should be a resounding ‘no’ to all three questions. In regard to the second and third question, I have sketched an argument to that effect in an earlier paper in this journal. In this paper, I offer a rejoinder to the critical reply offered by Stefan Müller-Doohm und Roman Yos on behalf of the Habermasian mainstream (...) in Frankfurt School Critical Theory. This rejoinder depends on giving a negative answer also to the first question. In rejecting the Habermasian idea of a programme of justification, I stand accused of dogmatism and, consequently, decisionism. I show that this accusation itself betrays a certain dogmatism – insofar as it accepts that such a programme of justification is undeniably possible and required, without consideration of evidence or arguments to the contrary. Self-reflective and critical theorising about society can, indeed must, take other forms. (shrink)
