________ 2 z T H E M E S Norman Fairclough, Bob Jessop, Andrew Sayer Critical Realism and Semiosis This paper explores the mutual implication of critical realism and semiosis. At least three major sets of questions can be posed in this regard. 1 First, we consider whether critical realism can afford to ignore semiosis, provisionally defined as the intersubjective production of meaning, 2 in its more general approach to social relations, their reproduction and transformation (see Section I). In discussing this issue we interpret social relations broadly to include not only individual actions and interactions but also the emergent properties of institutional orders and the domain of the lifeworld. Apart from addressing the closely related, controversial, but nonetheless analytically distinct, issue of whether reasons can also be causes, critical realists have paid little attention to the nature and significance of semiosis. Prioritising the former at the expense of the latter is quite unjustified because reasons are merely one (albeit important) aspect of the causal efficacy of semiosis. In addition, their effectiveness can only be understood in and through the operation of semiosis. Second, and equally important for our purposes, we inquire into the social preconditions and broader social context of semiosis. This set of problems is well suited to the application of critical discourse analysis because the latter can contextualise the production, communication, and reception of semiosis (see Chouliaraki and Fairclough 1999). But we also show that, depending on the explanandum, it may be necessary to supplement critical discourse analysis (hereafter CDA) through more concrete-complex analyses of extra-discursive domains. This implies that, insofar as semiosis has been studied in isolation from its context, this is bound to lead to an incomplete account of social causation and therefore risks committing one or more kinds of reductionism (see Section II). Finally, we turn to a third set of questions. These concern the nature of semiotic structures, their emergence from texts and textual practices, and their role in social structuration (see Section III). We exemplify these issues by drawing on critical semiotic analysis (especially CDA), which is a form of text analysis that is not only compatible with critical realism but also provides major insights into the role of semiosis in social structuration (see Section IV). Overall these two Sections seek to show that semiosis involves mechanisms that are intelligible from a critical realist point of view. Our concluding Section draws these different themes together to argue that semiotic analysis might benefit from paying attention to other aspects of critical realism and that critical realism might benefit from paying more attention to semiosis when exploring the social world. Addressing these three sets of questions involves identifying and exploring the real mechanisms of semiosis as a first step towards making progress on the larger problem of mind-body-semiosis-sociality-materiality. This is clearly an ambitious project and we do not expect to produce a solution in this paper. Moreover, since critical realism qua philosophy does not entail commitments to any particular substantive social or psychological theory, alternative critical realist accounts of semiosis could also be advanced. If so, we hope our own proposals will stimulate fellow critical realists to present them. I. WHY CRITICAL REALISM MUST ADDRESS SEMIOSIS Critical realism has tended to take semiosis for granted. For example, its practitioners often defend the claim that reasons can be causes without making any substantial reference to semiosis as such. Our first objective is to oppose this neglect. We will then demonstrate how a critical realist approach might be used to illuminate semiosis. Social theorists and discourse analysts routinely defend semiotic analysis on the grounds that semiosis has real effects on social practice, social institutions, and social order. They argue, in short, that semiosis is performative. Though it is certainly possible for us to communicate unintentionally, we normally speak or write in order to produce some kind of response. Yet answers to the question of how semiosis produces effects are generally conspicuous by their absence. This could well be due to the many uncertainties and/or controversies over the nature of explanation in the social sciences. For some social theorists, explaining how semiosis produces effects would require a causal explanation that first identifies what it is that produces observed effects and then attributes causal responsibility thereto in terms of an underlying causal mechanism (or mechanisms). But many other theorists reject causal explanation as being wholly inappropriate to the study of semiosis. For example, hermeneutics is generally taken to reject causal explanation (erklären) in favour of interpretive understanding (verstehen). Its advocates deny that semiosis and its effects can be explained in the same way as the production of chemical reactions and their effects; all that is possible (and all that is required) is to elucidate what a specific text ‘means’. This rejection of erklären in favour of verstehen is often tied to a Humean account of causal explanation in terms of ‘constant conjunctions’ between causes and effects. 3 Thus advocates of verstehen argue that, because such regularities either do not characterise communication or are irrelevant to its understanding, causal explanation is either totally excluded or simply redundant. Given the semiotic character of reasons (see below), this argument is linked to their conclusion that reasons are not to be treated as causes of behaviour. Instead, according to advocates of verstehen, reasons are propositions that precede or accompany behaviour and must simply be ‘understood’. If this line of reasoning were to be accepted, however, it would be
