Regulating criticism: some comments on an argumentative complex JONATHAN POTTER, DEREK EDWARDS and MALCOLM ASHMORE ABSTRACT This commentary identifies a range of flaws and contradictions in Parker’s critical realist position and his critique of relativism. In par- ticular we highlight: (1) a range of basic errors in formulating the nature of relativism; (2) contradictions in the understanding and use of rhetoric; (3) problematic recruitment of the oppressed to support his argument; (4) tensions arising from the distinction between working in and against psychology. We conclude that critical realism is used to avoid doing empirical work, on the one hand, and to avoid scholarly interdisciplinary engagement, on the other. Key words critical realism, interdisciplinary engagement, psychology, relativism, rhetoric INTRODUCTION For some time now Ian Parker and colleagues have been developing a dis- tinctive and complex position in psychology. It has become something of a discrete perspective in critical psychology, with its own publications, workshops, courses and now a house journal.
