This book will be of great interest to students and researchers alike across the social sciences and particularly in philosophy, economics and sociology.

The connections between Adam Smith and Catholic Social Teaching raise several questions. The principle of subsidiarity adopted in CST, according to which higher associations should not replace subordinate organizations on what the latter can do, seems to be in line with the idea that governmental intervention in the market sphere should be restricted to the minimum required, in line with what is typically seen as Smith’s view. But the principle of the common good would also recommend intervention from political authorities (...) in order to ensure that the common good is achieved. Here I shall argue that this question must be addressed taking into account another principle of CST, the principle of solidarity, and also the basic principle of CST, regarding human dignity. To do so, it is necessary to understand how the various principles of CST spring from the notion of imago Dei in CST, which is behind the notion of human dignity. This leads to a relational conception of human beings which can be fruitfully articulated with Smith’s moral philosophy and political economy. (shrink)

Mainstream game theory explains cooperation as the outcome of the interaction of agents who permanently pursue their individual goals. Amartya Sen argues instead that cooperation can only be understood by positing a type of rule-following behaviour that can be out of phase with the pursuit of individual goals, due to the existence of a collective identity. However, Sen does not clarify the ontological preconditions for the type of social behaviour he describes. I will argue that Sen's account of collective identity (...) can be best interpreted in the light of John Searle's notion of collective intentionality, while Sen's explanation of rule-following behavior and agency is best understood using the critical realist transformational model of social activity.

In this article I draw upon the social ontologies developed by John Searle, Roy Bhaskar, Margaret Archer and Tony Lawson in order to distinguish between power and leadership. To do so, I distinguish the different organizing principles behind natural phenomena, collective phenomena and institutional phenomena, and argue that an understanding of those different organizing principles is essential to a clearer conceptualization of power and leadership. Natural power and cultural power, as I argue, depend upon the organizing principles of natural phenomena, (...) and differ depending on whether those organizing principles have been transformed by humans, in which case it becomes cultural power, or not, in which case it simply is natural power. Leadership emerges with the ability of making other humans share mental states through collective intentionality. Institutional power, in contrast, is connected to the creation of a deontology of rights and obligations that provide what Searle calls desire-independent reasons for action. (shrink)

In this paper the use of mathematics in economics will be discussed, by comparing two approaches to mathematics, a Cartesian approach, and a Newtonian approach. I will argue that while mainstream economics is underpinned by a Cartesian approach which led to a divorce between mathematics and reality, the contributions of key authors of the Cambridge tradition, like Marshall, Keynes and Sraffa, are characterised by a Newtonian approach to mathematics, where mathematics is aimed at a study of reality. Marshall was influenced (...) by the Newtonian approach that still characterised many aspects of the Cambridge Mathematical Tripos, where the emphasis was on geometrical and mechanical examples rather than on symbolic (Cartesian) mathematics. Keynes, who criticised (Cartesian) symbolic mathematics, was indeed an admirer of Newton and of his method. Sraffa's mathematical constructions are also in line with the Newtonian approach where arithmetic and geometry were strictly separated, since Sraffa's mathematical constructions typically use arithmetic without engaging in the mixture between geometry and arithmetic that occurs in the Cartesian approach.

Rom Harré criticizes critical realism for ascribing causal powers to social structures, arguing that it is human individuals, and not social structures, that possess causal powers, and that a false conception of structural causation undermines the emancipatory potential of critical realism. I argue that an interpretation of the category of process as the spatio-temporalization of the category of structure, which underpins much evolutionary theory, provides the conceptual tools to explain how the critical realist transformational model of social activity can escape (...) from Harré’s criticism, leading to a general conception of social development within which various types of evolutionary processes can be identified as particular cases. I then argue that Tony Lawson’s PVRS model provides an evolutionary perspective that enables the conceptualization of coercive power as selective pressure. (shrink)

In this article I address the question of whether corporations should be considered as part of the basic structure of society as defined in Rawls’s Theory of Justice. To do so, it becomes necessary to understand which institutions are crucial for defining Rawls’s basic structure of society. I will argue that a social ontology aimed at understanding how human institutions influence various aspects presupposed in Rawls’s basic structure of society can help addressing this topic. To do so, I shall draw (...) upon the social ontology elaborated by Searle, who follows an approach that is particularly suitable for showing how Rawls’s basic structure of society already contains an institutional setting that must take corporations into account in its very formulation, due to the implications of the activities of the corporation for distributive justice.

In his new book The Idea of Justice, Amartya Sen argues that political theory should not consist only in the characterisation of ideal situations of perfect justice. In so doing, Sen is making, within the context of political theory, a similar argument to another he also made in economic theory, when crtiticising what he called the ?rational fool? of mainstream economics. Sen criticised the ideal and fictitious agent of mainstream economics, while advocating for a return to an integrated view of (...) ethics and economics, which characterised many classical political economists who inspired Sen's theory of justice, from Adam Smith to Karl Marx. I will examine Sen's revival of classical political economy, and argue that a revival of classical political economy, which was undertaken earlier by Piero Sraffa, has much potential for bringing a more plural and realist perspective to economics.

Coevolution between two antagonistic species has been widely studied theoretically for both ecologically- and genetically-driven Red Queen dynamics. A typical outcome of these systems is an oscillatory behavior causing an endless series of one species adaptation and others counter-adaptation. More recently, a mathematical model combining a three-species food chain system with an adaptive dynamics approach revealed genetically driven chaotic Red Queen coevolution. In the present article, we analyze this mathematical model mainly focusing on the impact of species rates of evolution (...) (mutation rates) in the dynamics. Firstly, we analytically proof the boundedness of the trajectories of the chaotic attractor. The complexity of the coupling between the dynamical variables is quantified using observability indices. By using symbolic dynamics theory, we quantify the complexity of genetically driven Red Queen chaos computing the topological entropy of existing one-dimensional iterated maps using Markov partitions. Co-dimensional two bifurcation diagrams are also built from the period ordering of the orbits of the maps. Then, we study the predictability of the Red Queen chaos, found in narrow regions of mutation rates. To extend the previous analyses, we also computed the likeliness of finding chaos in a given region of the parameter space varying other model parameters simultaneously. Such analyses allowed us to compute a mean predictability measure for the system in the explored region of the parameter space. We found that genetically driven Red Queen chaos, although being restricted to small regions of the analyzed parameter space, might be highly unpredictable. (shrink)

Résumé Dans cet article, je discute de la manière dont le réalisme critique en économie peut contribuer à l’élaboration d’une théorie économique et sociale alternative. Les contributions de la tradition de Cambridge en économie, qui a également influencé le réalisme critique en économie, se révèleront précieuses dans ce contexte. Je ferai valoir que, même si une reprise précoce de l’économie politique classique dans la tradition de Cambridge se concentre sur la reproduction des structures économiques, le réalisme critique en l’économie s’est (...) intéressé, quant à lui, à la reproduction des structures sociales. Ce dernier permet ainsi la reprise d’un cadre qui existait au sein de l’économie politique classique, et qui fut porté à son stade le plus avancé par Marx. Ce cadre est axé sur la reproduction économique d’un surplus, et sur sa distribution (institutionnelle) à travers les différentes classes sociales sous une structure sociale. L’ontologie sociale du réalisme critique nous permet de comprendre pourquoi l’étude de la reproduction d’un système (relationnel) est le meilleur point de départ pour le développement de la théorie économique et sociale.
