A Critique of Instrumental Reason in Economics

Abstract

There are, broadly speaking, two ways to think about rationality, as defined in the following passage: ‘Reason’ for a long time meant the activity of understanding and assimilating the eternal ideas which were to function as goals for men. Today, on the contrary, it is not only the business but the essential work of reason to find means for the goals one adopts at any given time. (Horkheimer, 1974, p. vii) To use what Horkheimer called objective reason, and what others have called expressive or non–instrumental reason, is to reflect on one's goals, to attempt to determine what preferences one ought to hold. On the other hand, to use what Horkheimer called subjective reason is to ‘be concerned with means and ends, with the adequacy of procedures for purposes more or less taken for granted’ (1947, p. 3), that is, to be instrumentally rational. This contrast between non-instrumental and instrumental reason is at the heart of many contemporary social and philosophical disputes.1

Homo economicus and the reconstruction of political economy: six theses on the role of values in economics

“…And for many this has a 9 See Hirschman (1985, p.15). 10 For more on this relationship between means and ends see Stewart (1995). 11 For an excellent account of the inadequacy of this defence see Blackburn (1998, chapter 6).…”

“…The same could be said for the current opposition to globalisation in the manner that it is proceeding. Stewart (1995) for instance has argued that we can understand Canadian opposition to NAFTA in part because of a desire to preserve a less competitive environment. Once more the recent research on 32 Ginsborg (2003, pp.…”

A Framework for Discussing Normative Theories of Business Ethics

“…19 This has been questioned; in the context of business ethics, di Norcia (1998) questions whether actual corporations try to maximize shareholder wealth; he suggests that survival of the firm takes priority. 20 Hamish Stewart (1995), for example, argues that economic theory needs to consider constitutive issues of welfare, as well as the instrumental issues of efficiency and productivity. 21 For an extended defense of strict separation of government and business responsibilities along these lines, see Jacobs 1992.…”

Chaos TheoryVersusHeisenberg's Uncertainty: Risk, Uncertainty and Economic Theory

“…As the agent tries to define the magnitude of self-ability, the ability undergoes developmental change. Such a self-defining process is the basis of what Herbert Simon (1976) names "procedural rationality" as opposed to the neoclassical "substantive rationality," or what Shaun Hargreaves Heap (1989) calls "expressive rationality" as opposed to the neoclassical "instru mental rationality" (see also Stewart, 1995).4…”
