Ian Hacking uses the looping effect to describe how classificatory practices in the human sciences interact with the classified people. While arguably this interaction renders the affected human kinds unstable and hence different from natural kinds, realists argue that also some prototypical natural kinds are interactive and human kinds in general are stable enough to support explanations and predictions. I defend a more fine-grained realist interpretation of interactive human kinds by arguing for an explanatory domain account of the looping effect. First, I argue that knowledge of the feedback mechanisms that mediate the looping effect can supplement, and help to identify, the applicability domain over which a kind and its property variations are stably explainable. Second, by applying this account to cross-cultural case studies of psychiatric disorders, I distinguish between congruent feedback mechanisms that explain matches between classifications and kinds, and incongruent feedback mechanisms that explain mismatches. For example, congruent mechanisms maintain Western auditory experiences in schizophrenia, whereas exporting diagnostic labels inflicts incongruence by influencing local experiences. Knowledge of the mechanisms can strengthen explanatory domains, and thereby facilitate classificatory adjustments and possible interventions on psychiatric disorders.

In this paper, I explore what gives collective testimony its epistemic credentials, through a critical discussion of three competing accounts of the epistemology of collective testimony. According to the first view, collective testimony inherits its epistemic credentials from the beliefs the testimony expresses—where this can be seen either as the beliefs of all or some of the group’s members, or as the beliefs of group itself. The second view denies any necessary connection to belief, claiming instead that the epistemic credentials of collective testimony derive from the reliability or truth-conduciveness of the statement that expresses the testimony. Finally, the third view claims that the epistemic credentials of collective testimony derive from the fact that it involves undertaking a collective commitment to trustworthiness, which makes the group susceptible to rebuke and blame if its testimony is not trustworthy. I argue that this last account holds the most promise for preserving what is distinctive about testimonial knowledge while still underwriting a robust epistemology of collective testimony.

Organisations are computing systems. The university’s sports centre is a computing system for managing sports teams and facilities. The tenure committee is a computing system for assigning tenure status. Despite an increasing number of publications in group ontology, the computational nature of organisations has not been recognised. The present paper is the first in this debate to propose a theory of organisations as groups structured for computing. I begin by describing the current situation in group ontology and by spelling out the thesis in more detail. I then present the example of a sports centre to illustrate why one might intuitively think of organisations as computing systems. To substantiate the thesis, I introduce Piccinini’s restrictive analysis of physical computation. As I show, organisations meet all criteria for being computing systems. Organisations are structured groups with the function of manipulating medium-independent vehicles according to rules. Furthermore, I argue for the modal claim that this is a necessary feature of organisations. Having sketched the computational account of organisations, I compare it to other proposals in the literature.

The suggestions outlined here include the following. Money is a bundle of institutionally sustained causal powers. Money is an institutional universal instantiated in generic currencies and particular money tokens. John Searle’s account of institutional facts is not helpful for understanding the nature of money as an institution (while it may help to illuminate aspects of the nature of currencies and money particulars). The money universal is not a social convention in David Lewis’s sense (while currencies and money particulars are characterized by high degrees of conventionality). The existence of the money universal is dependent on a larger institutional structure and cannot be understood in terms of collective belief or acceptance or agreement separately focusing on money. These claims have important implications for realism about money.

The folk conception of money as an object is not a promising starting point to develop general, explanatory metaphysical accounts of the social world. A theory of institutions as rules in equilibrium is more consistent with scientific theories of money, is able to shed light on the folk view, and side-steps some unnecessary puzzles.

The advent of virtual currencies such as bitcoin raises a pressing question for lawmakers, regulators, and judges: should bitcoin and other virtual currencies be classified as money or currency for legal and regulatory purposes? I examine two different approaches to answering this question—a descriptive approach and a normative approach. The descriptive approach says that bitcoin and other virtual currencies should be classified as money or currency just in case they really are money or currency, whereas the normative approach says that this question of classification should be answered on the basis of substantive normative considerations. I argue against the descriptive approach and in favor of the normative approach.

Teleological thinking about money reasons from what money is for to both how it ought to be used and what forms it should take. One type, found in Aristotle’s argument against usury, takes teleological considerations alone to decisively settle normative questions. Another type, found in Locke’s argument about monetary durability, takes teleological considerations to contribute to the settling of normative questions, but sees them as one consideration among many. This paper endorses the type made by Locke while rejecting the type made by Aristotle, and identifies further teleological tendencies in the work of Adam Smith and other philosophers.

The traditional Lockean justification of property rights has been argued to be no longer valid in a world in which much wealth does not derive from acquisitions of natural resources, and in which much property, such as money, is intangible. This means that libertarians need to reconsider whether and why property rights are justified for objects that fall outside of the scope of the Lockean justification. This paper gives a justification of property rights in relation to modern money, which uses the self-ownership principle as its central premise. Since modern money is a form of credit, I start with a justification of credit property rights. I then consider both money under gold convertibility and present-day fiat systems, showing that the justification of credit property rights remains valid under these conditions.
