Causal Eliminativism

In this work, I analyze our concept of cause in the face of criticism of Bertrand Russell in his article “On the Notion of Cause”. For Russell, there is an estrangement between the notion of cause and mature science of physics. The word cause (and its correlates) would not be used in physics, thus eliminating the main justification of philosophy for his job—the foundation of science. Thus, the various causal notions and the principle of causality should be abandoned by philosophers (...) as something outdated. The aim of this study is to assess the extent to which our notion of cause, with its asymmetric nature, can be explained by physics and investigate the question of the existence of causes in our world.

There is a huge chasm between the notion of lawful determination that figures in fundamental physics, and the notion of causal determination that figures in the "folk physics" of everyday objects. In everyday life, we think of the behavior of an ordinary object as being determined by a small set of simple conditions. But in fundamental physics, no such conditions suffice to determine an ordinary object's behavior. What bridges the chasm is that fundamental physical laws make the folk picture of (...) the world approximately true in certain domains. How? In part, by entailing that many objects are approximately isolated from most of their environments. Dynamical laws yield this result only in conjunction with appropriate statistical assumptions about initial conditions. (shrink)

What would it be for a process to happen backwards in time? Would such a process involve different causal relations? It is common to understand the time reversal invariance of a physical theory in causal terms, such that whatever can happen forwards in time (according to the theory) can also happen backwards in time. This has led many to hold that time reversal symmetry is incompatible with the asymmetry of cause and effect. This paper critiques the causal reading of time (...) reversal. First, I argue that the causal reading requires time-reversal-related models to be understood as representing distinct possible worlds, and on such a reading causal relations are compatible with time reversal symmetry. Second, I argue that the former approach does however raise serious sceptical problems regarding the causal relations of paradigm causal processes, and as a consequence there are overwhelming reasons to prefer a non-causal reading of time reversal whereby time reversal leaves causal relations invariant. On the non-causal reading, time reversal symmetry poses no significant conceptual nor epistemological problems for causation. -/- . (shrink)

Review of 'Causal Reasoning in Physics' by Mathias Frisch for British Journal for Philosophy of Science.

Bertrand Russell famously argued that causation is not part of the fundamental physical description of the world, describing the notion of cause as “a relic of a bygone age”. This paper assesses one of Russell’s arguments for this conclusion: the ‘Directionality Argument’, which holds that the time symmetry of fundamental physics is inconsistent with the time asymmetry of causation. We claim that the coherence and success of the Directionality Argument crucially depends on the proper interpretation of the ‘ time symmetry’ (...) of fundamental physics as it appears in the argument, and offer two alternative interpretations. We argue that: if ‘ time symmetry’ is understood as the time -reversal invariance of physical theories, then the crucial premise of the Directionality Argument should be rejected; and if ‘ time symmetry’ is understood as the temporally bidirectional nomic dependence relations of physical laws, then the crucial premise of the Directionality Argument is far more plausible. We defend the second reading as continuous with Russell’s writings, and consider the consequences of the bidirectionality of nomic dependence relations in physics for the metaphysics of causation.

Causal realism is the view that causation is a structural feature of reality; a power inherent in the world to produce effects, independently of the existence of minds or observers. This article suggests that certain problems in the philosophy of mind are artefacts of causal realism; because they presuppose the existence or possibility of a mind-independent causal nexus between the ‘physical’ and the ‘mental’. These dilemmas include the 'hard problem' of consciousness, and the problems of free will and mental causality. (...) Since the ostensible causal nexus cannot be directly perceived, it is sublimated into obscure and elusive phenomena along the purported mental causal chain. The antithesis of causal realism, and the proposed solution to the problems above, is causal anti-realism: the view that causation is not a fundamental property of the world, but of how observers purposively interpret ‘the world’. Causal anti-realism is compatible with causal pragmatism, which allows for the practical use of causal terms. Causal anti-realism denies the possibility of ontological reduction and is therefore incompatible with materialism. The article concludes that causal anti-realism is at least prima facie reconcilable with idealism. (shrink)

A number of philosophers have argued that causation is not an objective feature of the microphysical world but rather is a perspectival phenomenon that holds only between “coarse-grained” entities such as those that figure in the special sciences. This view seems to pose a problem for arguments for physicalism that rely on the alleged causal completeness of physics. In this paper, I address this problem by arguing that the completeness of physics has two components, only one of which is causal. (...) These two components of completeness can be used in an argument for physicalism that is supported by strong inductive evidence even in the absence of microphysical causation. (shrink)

Physicalism is sometimes portrayed by its critics as a dogma, but there is an empirical argument for the position, one based on the accumulation of diverse microphysical causal explanations in physics, chemistry, and physiology. The canonical statement of this argument was presented in 2001 by David Papineau. The goal of this paper is to demonstrate a tension that arises between this way of understanding the empirical case for physicalism and a view that is becoming practically a received position in philosophy (...) of physics: that microphysics does not support the existence of causal facts (and so does not support causal explanations). Indeed this is a conclusion embraced in recent work by Papineau himself. This paper examines a range of natural ways of avoiding this tension and reconciling the empirical case for physicalism with the rejection of microphysical causation. (shrink)

The difference between cause and effect seems obvious and crucial in ordinary life, yet missing from modern physics. Almost a century ago, Bertrand Russell called the law of causality 'a relic of a bygone age'. In this important collection 13 leading scholars revisit Russell's revolutionary conclusion, discussing one of the most significant and puzzling issues in contemporary thought.

We discuss Russell's 1913 essay arguing for the irrelevance of the idea of causation to science and its elimination from metaphysics as a precursor to contemporary philosophical naturalism. We show how Russell's application raises issues now receiving much attention in debates about the adequacy of such naturalism, in particular, problems related to the relationship between folk and scientific conceptual influences on metaphysics, and to the unification of a scientifically inspired worldview. In showing how to recover an approximation to Russell's conclusion (...) while explaining scientists' continuing appeal to causal ideas (without violating naturalism by philosophically correcting scientists) we illustrate a general naturalist strategy for handling problems around the unification of sciences that assume different levels of naïveté with respect to folk conceptual frameworks. We do this despite rejecting one of the premises of Russell's argument, a version of reductionism that was scientifically plausible in 1913 but is not so now. (shrink)

A specter is haunting Hume scholarship: the specter of the “New Hume.” Contrary to more traditional interpretations, according to which Hume rejects belief in any conception of causation that invokes (metaphysically) necessary connections between distinct existences, proponents of the New Hume hold that Hume at the least allowed for the possibility of such connections—it’s just that he thought we couldn’t know much, if anything, about them, if we assume that they do exist. -/- I will argue that the views of (...) the “New Humers” (as I shall call them) are mistaken. I will begin by discussing their reading of Hume on causation, using Galen Strawson as a foil. I then examine the relation between Hume’s view of relations (pun intended) and his account of “necessary connexions”. Next, I argue that this account, once properly understood, shows that he did not believe in what we would think of as necessary connections while at the same time explaining why, as the New Humers point out, Hume sometimes writes in ways that can make it sound like he does, as well as reconciling Hume’s two definitions of causation. After that, I answer objections, and then raise some doubts about Hume’s account before finally concluding the paper. (shrink)
