On its publication in 1957, _The Poverty of Historicism_ was hailed by Arthur Koestler as 'probably the only book published this year which will outlive the century.' A devastating criticism of fixed and predictable laws in history, Popper dedicated the book to all those 'who fell victim to the fascist and communist belief in Inexorable Laws of Historical Destiny.' Short and beautifully written, it has inspired generations of readers, intellectuals and policy makers. One of the most important books on the (...) social sciences since the Second World War, it is a searing insight into the ideas of this great thinker. (shrink)

The author draws on arguments from contemporary philosophy of mind to provide an argument for sociological collectivism. This argument for nonreductive individualism accepts that only individuals exist but rejects methodological individualism. In Part I, the author presents the argument for nonreductive individualism by working through the implications of supervenience, multiple realizability, and wild disjunction in some detail. In Part II, he extends the argument to provide a defense for social causal laws, and this account of social causation does not require (...) any commitment to intentionality or agency on the part of individuals.

In Part I, the author argued for nonreductive individualism (NRI), an account of the individual-collective relation that is ontologically individualist yet rejects methodological individualism. However, because NRI is ontologically individualist, social entities and properties would seem to be only analytic constructs, and if so, they would seem to be epiphenomenal, since only real things can have causal power. In general, a nonreductionist account is a relatively weak defense of sociological explanation if it cannot provide an account of how social properties (...) can participate in causal relations. In this article, the author extends NRI to address this weakness and provides an account of social causation that he refers to as supervenient causation. Key Words: individualism • collectivism • social realism • social causation. (shrink)

Popper’s theory of World 3 is often regarded as incongruent with his defense of methodological individualism. This article criticizes this widespread view. Methodological individualism is said to be at odds with three crucial assumptions of the theory of World 3: the impossibility of reducing World 3 to subjective mental states because it exists objectively, the view that the mental functions cannot be explained by assuming that individuals are isolated atoms, and the idea that World 3 has causal power and influences (...) both individual minds and actions. This article demonstrates that the inconsistency thesis stems from a confusion between methodological individualism as understood by Popper and reductionism. The reasons for this confusion are analyzed and clarified. It is argued that two variants of methodological individualism can be distinguished, and that unlike psychologistic individualism, Popper’s nonatomistic individualism is fully consistent with his theory of World 3.

“Di Iorio offers a new approach to Hayek’s Sensory Order, linking neuroscience to the old Verstehen tradition and to contemporary theories of self-organizing systems; this should be on the reading list of everyone who is interested in Hayek’s thought.” Barry Smith University at Buffalo, editor of The Monist “This impressive and well-researched book breaks new ground in our understanding of F.A. Hayek and of methodological individualism more generally. It shows that methodological individualism sanctions neither an atomistic view of society nor (...) a mechanical determinism. The book carefully analyzes an important tradition in the social sciences, and compares it to many important philosophical, sociological and economic systems of thought. This is an enlightening book for all scholars interested in the methodological problems of the social sciences.” Mario J. Rizzo New York University “One of Hayek’s most important contributions is his linking of complex methodological individualism, which deals with the emergence of spontaneous orders and unintended collective structures in complex self-organizing social systems, with a cognitive psychology. What makes Francesco Di Iorio’s book of great interest is that, by building on Hayek’s seminal book The Sensory Order, it deepens the connections between cognition and rules of just conduct, taking into account relevant theories on subjectivity and consciousness such as phenomenology, hermeneutics and enactivism.” Jean Petitot École des Hautes Études en Sciences Sociales, EHESS, Paris “In this thoughtful and enlightening book Francesco Di Iorio uses Hayek’s cognitive psychology as the starting point for investigation of the relationship between the autonomy of the agent and socio-cultural influences within methodological individualism. The book provides an illuminating and innovative analysis of a central issue in the philosophy of social science by setting Hayek’s view on mind and action in fruitful relation to approaches such as Gadamer’s hermeneutics, Merleau-Ponty’s phenomenology, Varela’s and Maturana’s enaction, Boudon’s interpretative sociology, Popper’s fallibilism and Mises’ praxeology. One of the most interesting aspects of this book is its argument that hermeneutics and fallibilism refer not to two different methods but to the same one.” Dario Antiseri Emeritus Professor at LUISS University, Rome “Francesco Di Iorio’s book explores, in an original way, the connections between Hayek’s methodological individualism and his fascinating idea that human mind is both an interpretative device and a self-organizing system. It is a brilliant, clearly written work, characterized by a certain intellectual courage, which makes a remarkable contribution to the sociology of knowledge.” Gérald Bronner Paris Diderot University.

Discusses the importance and development of analytical sociology, emphasizing the centrality of mechanisms in explaining social life.

Some argue, following Bertrand Russell, that because general truths are not entailed by particular truths, general facts must be posited to exist in addition to particular facts. I argue on the contrary that because general truths (globally) supervene on particular truths, general facts are not needed in addition to particular facts; indeed, if one accepts the Humean denial of necessary connections between distinct existents, one can further conclude that there are no general facts. When entailment and supervenience do not coincide (...) it is only failure of supervenience, not failure of entailment, that carries ontological import. (shrink)

The anthropocentric view holds that the social world is a projection of mental states and attitudes onto the real world. However, there is more to a society of individuals than their psychological make up. In The Ant Trap, Epstein hints at the possibility that collective intentionality can, and should, be discarded as a pillar of social ontology. In this commentary I argue that this claim is motivated by an outdated view of the nature and structure of collective attitudes. If we (...) aim at a good theory of social ontology, we need a good theory of collective intentionality. (shrink)

The distinction between anchors and grounds is one of the most innovative contributions of The Ant Trap. In this commentary I will argue that the distinction suffers from an ambiguity between tokens and types. This leads Epstein to endorse pluralism about anchors and grounds, a position that is not justified in the book and to which there are plausible alternatives.
