The last decade has seen an increasing number of references to quantum mechanics in the humanities and social sciences. This development has in particular been driven by Karen Barad’s agential realism: a theoretical framework that, based on Niels Bohr’s interpretation of quantum mechanics, aims to inform social theorizing. In dealing with notions such as agency, power, and embodiment as well as the relation between the material and the discursive level, the influence of agential realism in fields such as feminist science (...) studies and posthumanism has been profound. However, no one has hitherto paused to assess agential realism’s proclaimed quantum mechanical origin including its relation to the writings of Niels Bohr. This is the task taken up here. We find that many of the implications that agential realism allegedly derives from a Bohrian interpretation of quantum mechanics dissent from Bohr’s own views and are in conflict with those of other interpretations of quantum mechanics. Agential realism is at best consistent with quantum mechanics and consequently, it does not capture what quantum mechanics in any strict sense implies for social science or any other domain of inquiry. Agential realism may be interesting and thought provoking from the perspective of social theorizing, but it is neither sanctioned by quantum mechanics nor by Bohr’s authority. This conclusion not only holds for agential realism in particular, it also serves as a general warning against the other attempts to use quantum mechanics in social theorizing. (shrink)

Hilbert's axiomatization program of physical theories met an interesting challenge when it confronted the rise of quantum mechanics in the mid-twenties. The novelty of the mathematical apparatus of the then newly born theory was to be matched only by its substantial lack of any definite physical interpretation. The early attempts at axiomatization, which are described here, reflect all the difficulty of the task faced by Jordan, Hilbert, von Neumann and others. The role of von Neumann is examined in considerable detail (...) as he can be viewed here as the most outstanding of Hilbert's heirs. Von Neumann, especially in his work devoted to the proof of the impossibility of hidden variables, not only continued Hilbert's program but pushed it to its very limits, blending axiomatic rigor and interpretative commitment.

Due to the intense selection pressure against inbreeding, humans are expected to possess psychological adaptations that regulate mate choice and avoid inbreeding. From a gene’s-eye perspective, there is little difference in the evolutionary costs between situations where an individual him/herself is participating in inbreeding and inbreeding among other close relatives. The difference is merely quantitative, as fitness can be compromised via both routes. The question is whether humans are sensitive to the direct as well as indirect costs of inbreeding. Using (...) responses from a large population-based sample (27,364 responses from 2,353 participants), we found that human motivations to avoid inbreeding closely track the theoretical costs of inbreeding as predicted by inclusive-fitness theory. Participants were asked to select in a forced choice paradigm, which of two acts of inbreeding with actual family members they would want to avoid most. We found that the estimated fitness costs explained 83.6% of participant choices. Importantly, fitness costs explained choices also when the self was not involved. We conclude that humans intuit the indirect fitness costs of mating decisions made by close family members and that psychological inbreeding avoidance mechanisms extend beyond self-regulation.

Bastiat's great contribution to economics, in his own view, was his identification of service as the source of economic value. What is anything worth to anybody? In the cases where we are not dealing with what our fellow men do for us, the answer is to be found in its utility - how much the thing contributes to our satisfaction. In the case where we deal with our fellows, we are interested specifically in what they can do for us, that (...) is, how much service they can render us - how much they can or could, by their actions, contribute to the purchaser's satisfactions. If the providers are free beings, then the recipient will obtain those satisfactions only by agreement with that provider. It is to be assumed that the purchaser will get the best outcome he can: he will pay the lowest price feasible, for the option that is better than any known alternative. (shrink)

In this encyclopedia entry I canvass the current interpretations of John Locke's concept of Real Essence and the role it plays in his philosophy.

ABSTRACTBased on an overview of the ways in which politics and the political have been thought in critical discourse analysis, the author calls for a focus on the metapolitical dimension of discourse. The author develops his notion of metapolitics on the basis of post-foundational insights into politics, the political and processes of politicization. Metapolitics refers to projects and struggles where conflicting modes and models of politics clash. Metapolitical debates potentially reshape the structure of the public realm as well as the (...) entities, borders and processes that constitute it. The author differentiates his descriptive and analytic use of the term from the way this signifier has been used programmatically by the anti-democratic New Right and its heirs. He demonstrates that metapolitical projects can be democratic as well as anti-democratic. In order to facilitate discourse analyses of metapolitical projects, debates and struggles, the author suggests that the metapolitical dimension of contemporary debates can be explored further by integrating insights from governmentality studies, studies of political rationality and the discourse theoretical logics approach with CDA. Moreover, a further exploration of the linguistic and textual underpinnings of metapolitics constitutes a promising pathway for future investigation. The study of metapolitics should be part and parcel of the transdisciplinary domain of critical discourse studies so that our understanding of the linguistic and non-linguistic features of metapolitical projects can be developed in equal measure at multiple levels of abstraction.

This paper explores the fact that linear opinion pooling can be represented as a Bayesian update on the opinions of others. It uses this fact to propose a new interpretation of the pooling weights. Relative to certain modelling assumptions the weights can be equated with the so-called truth-conduciveness known from the context of Condorcet's jury theorem. This suggests a novel way to elicit the weights.

It is widely thought that Robert Nozick’s views on rectification of past injustices are of critical importance to his theory of distributive justice, even perhaps justifying wholesale redistributive taxes in the present because of the undoubted injustices that have pervaded much past history. This essay undertakes to correct this impression—not mostly by disagreeing with Nozick’s claims, but nevertheless proceeding on basic libertarian theory. Of enormous importance is the role of putative innocents, who are defrauded by miscreants carefully covering their tracks (...) so that these recipients have no reason to think they are buying stolen property. But of equal importance is simply that the duty to rectify past injustices is not comparable to the original duty to respect property rights in the first place. (shrink)

Some modern philosophers have retrieved the old idea that the identification of facts and events is dependent on language. For instance, Davidson holds that ...

This paper discusses ἐπιβολαὶ τῆς διανοίας, which later Epicureans are supposed to have elevated to a fourth criterion of truth to complement perceptions, preconceptions and feelings. By examining Epicurus’ extant writings, the paper distinguishes three different senses of the term: ‘thought in general’, ‘act of attention’ and ‘mental perception’. It is argued that only the sense ‘mental perception’ yields a plausible reading of ἐπιβολαί as a criterion of truth. The paper then turns to the textual evidence on ἐπιβολαί in later (...) authors. While the term ἐπιβολή is not used by Cicero, Lucretius and Philodemus in the sense of mental perception, it is argued that this still is the most plausible way of understanding ἐπιβολή as a criterion of truth.

In the literature, regress arguments often take one of two different forms: either they conclude that a given solution fails to solve any problem of a certain kind (the strong conclusion), or they conclude that a given solution fails to solve all problems of a certain kind (the weaker conclusion). This gives rise to a logical problem: do regresses entail the strong or the weaker conclusion, or none? In this paper I demonstrate that regress arguments can in fact take both (...) forms, and clearly set out the logical difference between them. Throughout the paper, I confine myself to metaphysical examples from the early Russell. Only now that we know they are valid can we start to discuss whether they are sound. (shrink)

L’inquiétude de la totalité de la vie, qui s’éveille chez certains esprits, les amène à créer des représentations canoniques, types de vie stylisée et unifiée. Les philosophes sont des créateurs de « canons » de vie philosophique ; mais on peut se demander s’il est possible de dresser un tableau idéal du philosophe qui pourrait lui servir en même temps de norme et de critère. Non, car la vie philosophique est un mouvement, un « acte imparfait » dont la fin (...) nous échappe ; nous la poursuivons par des voies profondément personnelles ; c’est pourquoi on ne saurait « canoniser » un philosophe.
