Bunge (2000) distinguishes two main methodological approaches of holism and individualism, and associates with them policy prescriptions of centralism and laissez-faire. He identifies systemism as a superior approach to both the study and management of society. The present paper, seeking to correct and develop this line of thought, suggests a more complex relation between policy and methodology. There are two possible methodological underpinnings for laissez-faire: while writers such as Friedman and Lucas fit Bunge’s pattern, more sophisticated advocates of laissez-faire, such (...) as Smith and Hayek, base their policy prescription in a methodology quite divergent from the individualism Bunge describes.

In a world of partially overlapping and partially conflicting interests there is good reason to doubt that self-seeking behaviour at the micro-level will spontaneously lead to desirable social outcomes at the macro-level. Nevertheless, some sophisticated economic writers advocating a laissez-faire policy prescription have proposed various 'invisible hand' mechanisms which can supposedly be relied upon to 'educe good from ill'. Smith defended the 'simple system of natural liberty' as giving the greatest scope to the unfolding of God's will and the working (...) out of 'natural' providential processes free of interference by 'artificial' state intervention - the expression not of divine order but of fallible human reason. Hayek, adopting a similar policy stance, based it in an evolutionary process in which those institutional forms best adapted to reconciling individual interests would, he believed, spontaneously be selected for in the inter-group struggle for survival. Keynes shares the holistic approach of Smith and Hayek, but without their reliance on invisible hand mechanisms. If spontaneous processes cannot be relied upon to generate desirable social outcomes then we have to take responsibility for achieving this ourselves by establishing the appropriate institutional framework. Keynes takes a historical view of the role of capitalism and analyses its pathology as rooted in what we would now refer to as a multi-player prisoners' dilemma. The paper draws out the significance of his methodological standpoint here. Keynes's policy standpoint assigns a critical role to his own class, the 'educated bourgeoisie' in the reform process he maps out. A distinction, but also an intimate connection, is highlighted between, on the one hand, micro-level individualism (the 'Manchester System, and, on the other, the macro-level collective action ('planning') required to preserve it. Finally Keynes is considered in relation to the themes of laissez-faire, holism, reductionism, providentialism and the invisible hand. (shrink)

This thesis argues for the fundamental importance of the opposition between holistic and reductionistic world-views in economics. Both reductionism and holism may nevertheless underpin laissez-faire policy prescriptions. Scrutiny of the nature of the articulation between micro and macro levels in the writings of economists suggests that invisible hand theories play a key role in reconciling reductionist policy prescriptions with a holistic world. An examination of the prisoners' dilemma in game theory and Arrow's impossibility theorem in social choice theory sets the (...) scene. The prisoners' dilemma epitomises the collective irrationality coordination problems lead to. The source of the dilemma is identified as the combination of interdependence in content and independence in form of the decision making process. Arrovian impossibility has been perceived as challenging traditional views of the relationship between micro and macro levels in economics. Conservative arguments against the possibility in principle of a social welfare function are criticised here as depending on an illicit dualism. The thesis then reviews the standpoints of Smith, Hayek and Keynes. For Smith, the social desirability of individual self-seeking activity is ensured by the 'invisible hand' of a god who has moulded us so to behave, that the quantity of happiness in the world is always maximised. Hayek seeks to re-establish the invisible hand in a secular age, replacing the agency of a deity with an evolutionary mechanism. Hayek's evolutionary theory, criticised here as being based on the exploded notion of group selection, cannot underpin the desirability of spontaneous outcomes. I conclude by arguing that Keynes shares the holistic approach of Smith and Hayek, but without their reliance on invisible hand mechanisms. If spontaneous processes cannot be relied upon to generate desirable social outcomes then we have to take responsibility for achieving this ourselves by establishing the appropriate institutional framework to eliminate macroeconomic prisoners' dilemmas.
