A Neglected Route to Realism About Quantum Mechanics

Bell's Theorem assumes that hidden variables are not influenced by future measurement settings. The assumption has sometimes been questioned, but the suggestion has been thought outlandish, even by the taxed standards of the discipline. (Bell thought that it led to fatalism.) The case for this reaction turns out to be surprisingly weak, however. We show that QM easily evades the standard objections to advanced action. And the approach has striking advantages, especially in avoiding the apparent conflict between Bell's Theorem and special relativity. The second part of the paper considers the broader question as to why advanced action seems so counterintuitive. We investigate the origins of our ordinary intuitions about causal asymmetry. It is argued that the view that the past does not depend on the future is largely anthropocentric, a kind of projection of our own temporal asymmetry. Many physicists have also reached this conclusion, but have thought that if causation has no objective direction, there is no objective content to an advanced action interpretation of QM. This turns out to be a mistake. From the ordinary subjective perspective, we can distinguish two sorts of objective world: one "looks as if" it contains only forward causation, the other ``looks as if'' it involves a mix of backward and forward causation. This clarifies the objective core of an advanced action interpretation of QM, and shows that there is an independent symmetry argument in favour of the approach.Comment: 35 pages, LaTex (forthcoming in MIND, July 1994; written for a philosophical audience, but perhaps of some interest here

What Might a Theory of Causation Do for Sport?

The purpose of this research is to articulate how a theory of causation might be serviceable to a theory of sport. This article makes conceptual links between Bernard Suits’ theory of game-playing, causation, and theories of causation. It justifies theories of causation while drawing on connections between sport and counterfactuals. It articulates the value of theories of causation while emphasizing possible limitations. A singularist theory of causation is found to be more broadly serviceable with particular regard to its analysis of sports

Mechanisms, counterfactuals and laws

In this chapter we examine the relation between mechanisms and laws/counterfactuals by revisiting the main notions of mechanism found in the literature. We distinguish between two different conceptions of ‘mechanism’: mechanisms-of underlie or constitute a causal process; mechanisms-for are complex systems that function so as to produce a certain behavior. According to some mechanists, a mechanism fulfills both of these roles simultaneously. The main argument of the chapter is that there is an asymmetrical dependence between both kinds of mechanisms and laws/counterfactuals: while some laws and counterfactuals must be taken as primitive (non-mechanistic) facts of the world, all mechanisms depend on laws/counterfactuals

Causality in concurrent systems

Concurrent systems identify systems, either software, hardware or even biological systems, that are characterized by sets of independent actions that can be executed in any order or simultaneously. Computer scientists resort to a causal terminology to describe and analyse the relations between the actions in these systems. However, a thorough discussion about the meaning of causality in such a context has not been developed yet. This paper aims to fill the gap. First, the paper analyses the notion of causation in concurrent systems and attempts to build bridges with the existing philosophical literature, highlighting similarities and divergences between them. Second, the paper analyses the use of counterfactual reasoning in ex-post analysis in concurrent systems (i.e. execution trace analysis).Comment: This is an interdisciplinary paper. It addresses a class of causal models developed in computer science from an epistemic perspective, namely in terms of philosophy of causalit

What Taylor Swift and Beyoncé Teach Us About Sex and Causes

In the consolidated cases Altitude Express v. Zarda, Bostock v. Clayton County, and R.G. & G.R. Harris Funeral Homes v. EEOC, the Supreme Court will decide whether or not Title VII prohibits discrimination on the basis of sexual orientation or gender identity. Although the parties disagree as to the appropriate formulation of a but-for test to determine whether or not there was a discriminatory outcome, all parties do agree to the use of such a test, which asks “whether the evidence shows ‘treatment of a person in a manner which but for that person’s sex would be different.’” City of Los Angeles, Dep’t. of Water and Power v. Manhart, 435 U.S. 702, 711 (1978). However, but-for tests confuse more than they clarify the inquiry; a discriminatory outcome cannot be explained by appeal to just a discrete characteristic of a particular person. Individuals are not discriminated against because of these characteristics per se. Rather, they are discriminated against because of the social meanings and expectations that attach to these characteristics. Beyoncé and Taylor Swift illustrate the difference between individual-level causation and social explanation in two separate songs, “If I Were a Boy” and “The Man.” The explanation for why the counterfactual ‘male’ Beyoncé and Swift are evaluated differently than their current ‘female’ versions does not lie in individual-level features considered apart from the social world, but in social-level roles and expectations associated with those features. For this reason, a social explanation test—one that asks whether the social meanings of sex characteristics, rather than the characteristics per se, explain the outcome in question—is more suitable for determining whether or not Title VII has been violated

The metaphysics of Machian frame-dragging

The paper investigates the kind of dependence relation that best portrays Machian frame-dragging in general relativity. The question is tricky because frame-dragging relates local inertial frames to distant distributions of matter in a time-independent way, thus establishing some sort of non-local link between the two. For this reason, a plain causal interpretation of frame-dragging faces huge challenges. The paper will shed light on the issue by using a generalized structural equation model analysis in terms of manipulationist counterfactuals recently applied in the context of metaphysical enquiry by Schaffer (2016) and Wilson (2017). The verdict of the analysis will be that frame-dragging is best understood in terms of a novel type of dependence relation that is half-way between causation and grounding
