Whereas many philosophers take backwards causation to be impossible, the few who maintain its possibility either take it to be absent from the actual world or else confined to theoretical physics. Here, however, I argue that backwards causation is not only actual, but common, though occurring in the context of our social institutions. After juxtaposing my cases with a few others in the literature and arguing that we should take seriously the reality of causal cases in (...) these contexts, I consider several objections. These objections involve whether the cases should be reinterpreted, whether they are properly within the institution, whether they involve necessitation or else Cambridge changes, whether and how they involve changing the past, and whether this should call us to question institutional reality. I end by suggesting that it is a virtue of our institutions that they allow backwards causation, that this is a kind of technology that they are often built to incorporate. (shrink)

I argue that the past can be objectively chancy in cases of backwards causation, and defend a view of chance that allows for this. Using a case, I argue against the popular temporal view of chance, according to which chances are defined relative to times, and all chancy events must lie in the future. I then state and defend the causal view of chance, according to which chances are defined relative to causal histories, and all chancy events must (...) lie causally downstream. The causal view replicates the intuitively correct results of the temporal view in cases of ordinary forwards causation, while correctly handling cases of backwards causation. I conclude that objective chance is more closely related to the direction of causation than it is to the direction of time. (shrink)

argues that the success of the backward causation hypothesis in quantum mechanics would provide strong support for a version of Reichenbach's account of the direction of causal processes, which takes the direction of causation to rest on the fork asymmetry. He also criticises my perspectival account of the direction of causation, which takes causal asymmetry to be a projection of our own temporal asymmetry as agents. In this reply I take issue with Dowe's argument at three main (...) points: his claim that the backward causation hypothesis in QM is incompatible with my perspectival approach to the direction of causation; his defence of the fork asymmetry approach against a general criticism of mine based on the time-symmetry of microphysics; and his application of his preferred account of the direction of causal processes to the relevant cases in QM.

Here are some intuitions we have about the nature of space and time. There is something fundamentally different about the past, present, and future. What is definitive of the past is that the past events are fixed. What is definitive of the future is that future events are not fixed. What is definitive of the present is that it marks the objective ontological border between the past and the future and, by doing so, instantiates a particularly salient phenomenological property of (...) nowness. Call the combination of these intuitions according to which there exists an objective present, a fixed past, and an open future, the intuitive view. I argue that, given the intuitive view, the possibility of backwards causation—and hence, for instance, backwards time travel—is problematic. (shrink)

Sometimes also called retro causation. A common feature of our world seems to be that in all cases of causation, the cause and the effect are placed in time so that the cause precedes its effect temporally. Our normal understanding of causation assumes this feature to such a degree that we intuitively have great difficulty imagining things differently. The notion of backward causation, however, stands for the idea that the temporal order of cause and effect is (...) a mere contingent feature and that there may be cases where the cause is causally prior to its effect but where the temporal order of the cause and effect is reversed with respect to normal causation, i.e. there may be cases where the effect temporally, but not causally, precedes its cause. (shrink)

Can a present or future event bring about a past event? An answer to this question is demanded by many other interesting questions. Can anybody, even a god, do anything about what has already occurred? Should we plan for the past, as well as for the future? Can anybody precognise the future in a way quite different from normal prediction? Do the causal laws and the past jointly preclude free action? Does current physical theory entail a consistent version of (...) class='Hi'>backwards causation? Recent articles on the problem of backwards causation have drawn attention to the importance of the principle of the fixity of the past: that the past is now fixed. It can be shown that the standard argument against backwards causation (the bilking experiment) simply builds in the assumption of past fixity. A fixed past deprives future events of past efficacy. This has naturally led to the speculation that by abandoning past fixity real power over the past may be possible.In this paper I show that in order to have an interesting thesis of backwards causation it is not enough simply to drop past fixity. More must go. In particular, to ensure what could be called future-to-past efficacy we must abandon two entrenched principles of permanence: the principle of permanent fixity, and the principle of permanent truth. The only alternative for backwards causal theorists is to embrace real contradictions in nature. (shrink)

The ability to anticipate the future is of great benefit to any organism. Whenever such a foreseeing takes place, it typically happens because an organism has been able to learn about some regularity in the past and then uses this information to expect some happenings in the future. Modern human beings have perfected this capacity far beyond any other animal by getting to know the laws by which nature operates. But it is still based on past experience that even human (...) beings are able to say something about the future. So every form of anticipation of the future relies on inductive reasoning based on knowledge of causal processes in the past. Both these processes and the processes by which we learn to anticipate the future are common in the sense that it is always an earlier cause that brings about a later effect. The ability to anticipate depends on the fact that our cognitive faculties only work on information that stems from the past. Had it been possible for us to receive reliable information about the future, the ability of anticipation might not have existed or might have been less faulty than it sometimes is. (shrink)

According to David Albert, there are certain situations where we can cause events that lie in our past. In response to a well-known objection that we never observe backward causation, he argues that there are good reasons why we can’t tell when it obtains. However, I identify another difficulty with Albert’s view: at face value, it has the unattractive consequence that backward causation is not just possible, but rife. In this article, I show how this implication can be (...) blocked. I then use my analysis to defend Albert’s account from a second well-known objection, namely, that it allows us to control the past. (shrink)

We propose an analysis of backward causation in terms of interventionism that can avoid several problems typically associated with backward causation. Its main advantage over other accounts is that it allows for reducing the problematic task of supporting backward causal claims to the unproblematic task of finding evidence for several ordinary forward directed causal hypotheses.

Dowe (1996) argues that the success of the backward causation hypothesis in quantum mechanics would provide strong support for a version of Reichenbach's account of the direction of causal processes, which takes the direction of causation to rest on the fork asymmetry. He also criticises my perspectival account of the direction of causation, which takes causal asymmetry to be a projection of our own temporal asymmetry as agents. In this reply I take issue with Dowe's argument at (...) three main points: his claim that the backward causation hypothesis in QM is incompatible with my perspectival approach to the direction of causation; his defence of the fork asymmetry approach against a general criticism of mine based on the time-symmetry of microphysics; and his application of his preferred account of the direction of causal processes to the relevant cases in QM.

In our world we never observe an effect which is earlier than its cause. All of our experience is of future-directed causation. But many have thought that backwards causation is at least logically or metaphysically possible. Max Black famously argued against this thought. I think his argument fails, but it’s still instructive. The correct rejoinder to Black teaches us what backwards causation must be like in a world of free agents, and implies that we can (...) never have reason to bring about past events. (shrink)

Philosophers dispute whether an effect can be earlier than its cause (i.e. whether backwards causation can occur). For example, could a trainwreck cause a psychic to have earlier knowledge of it? Max Black tried to show backwards causation to be impossible but he failed to do so, or so I will argue. Nonetheless, his famous article can still teach us something important about certain cases of backwards causation.

Whether we’re reading H.G. Wells, Robert Heinlein, Ray Bradbury, or Kurt Vonnegut, time travel is a wonderful narrative trick, freeing a story from the normal ‘one damn thing after another’ progression of time. But many philosophers claim it can never be more than that because backwards causation in general, and time travel in particular, are logically impossible.In this paper I examine one type of argument commonly given for this disappointing conclusion: the time travel paradoxes. Happily for science fiction (...) fans, these arguments fall far short of showing what they are intended to show. Why they fail can be better understood in the light of an analogy between these arguments and some arguments libertarians offer against determinism. (shrink)

Bell’s theorem requires the assumption that hidden variables are independent of future measurement settings. This independence assumption rests on surprisingly shaky ground. In particular, it is puzzlingly time-asymmetric. The paper begins with a summary of the case for considering hidden variable models which, in abandoning this independence assumption, allow a degree of ‘backward causation’. The remainder of the paper clarifies the physical significance of such models, in relation to the issue as to whether quantum mechanics provides a complete description (...) of physical reality.

This paper consists of a combination of material from sections 3.2, 4.5, and 4.6 from the 1997 edition of Time, Tense, and Causation, together with material added to correct an error in that earlier discussion. The added material was then used in the revised, paperback edition of Time, Tense, and Causation (2000), partly in section 4.6.2, but mainly in the Appendix.

Since Michel Dummett published “Can an effect precede its cause?”, in which he argued for the logical consistency of backwards causation, the controversial concept has turned to a subject of all kinds of interpretations and misinterpretations. Some like Ben-yami, Peijnenburg and Gorovitz have wrongly ascribed to Dummett the view that the argument for the consistency of believing in backwards causation applies only in cases where the agent doesn’t know about the occurrence of the past effect. In (...) this paper I defend Dummett’s argument by clearing up the confusion caused by ascribing the ignorance condition to Dummett. (shrink)

Dummett and others have failed to show that an effect can precede its cause. Dummett claimed that 'backwards causation' is unproblematic in agentless worlds, and tried to show under what conditions it is rational to believe that even backwards agent-causation occurs. Relying on considerations originating in discussions of special relativity, I show that the latter conditions actually support the view that backwards agent-causation is impossible. I next show that in Dummett's agentless worlds explanation does (...) not necessitate backwards causation. I then show why even relative backwards causation is impossible in his and Tooley's scenarios of parallel processes in which causes apparently act in opposite temporal directions. We thus have good reasons for thinking that backwards causation is impossible. (shrink)

The recent operationalization of the famous Newcomb's game by Schmidt (1998) offers an interesting and thought-provoking look at the plausibility of backward causation in a Newtonian universe. Hereby we investigate two details of the Schmidt's scenario which may, at least in principle, invalidate his conclusion in two different domains: one dealing with the issue of Newtonian predictability in specific instance of human actions, and the other stemming from a possible strategy aimed at obviating the anthropically oriented view of backward (...) causation as applied to a judicial and ethical problem posed by a version of the scenario. We conclude that the scenario is at least to be more complex than originally presented in order to remain viable. However, it points to a very deep and delicate question of compatibility of backward causation with the conventional ethical standards. (shrink)

In this discussion paper I argue that Max Black's well-known bilking argument does not succeed in showing the impossibility of backwards causation.

David Lewis famously defends a counterfactual theory of causation and a non-causal, similarity-based theory of counterfactuals. Lewis also famously defends the possibility of backward causation. I argue that this combination of views is untenable—given the possibility of backward causation, one ought to reject Lewis's theories of causation and counterfactuals.

Resumo Neste texto, o autor concentra-se em dois artigos históricos: o de Max Black “Why cannot an effect precede its cause”? e o de Michael Dummett “Bringing about the Past”. O autor irá mostrar onde falha o “bilking argument” de Black, contra a possibilidade da causalidade invertida. Por conseguinte, o autor irá concordar com Dummett, na possibilidade de um agente actuar a fim de que algo possa ocorrer no passado, contudo, discordando da argumentação de Dummett face a um desafio céptico, (...) que tenta mostrar a inutilidade de afectar o passado. Palavras-chave : Black, causalidade invertida, Dummett, razões, tempoIn this discussion I focus on two classic articles: Max Black’s ‘Why cannot an effect precede its cause?’ and Michael Dummett’s ‘Bringing about the Past’. I argue that Black’s bilking argument against the possibility of backwards causation fails. I agree with Dummett that the idea of an agent acting in order that something should have happened in the past is not absurd, but I disagree with Dummett’s response to a sceptical challenge which attempts to show that it is pointless to attempt to affect the past. Keywords : backwards causation, Black, Dummett, reasons, time. (shrink)

Kenneth Silver has recently argued that backwards causation is common in the context of social institutions. I consider this claim in detail and conclude that backwards causation is not the most plausible interpretation of what is going on in the cases Silver considers. Nonetheless, I show that these cases can teach us some interesting lessons about institutional facts. In particular, I argue that in order to avoid contradiction due to conflicting declarations in these cases, we must (...) conclude that the properties involved in institutional facts are relational properties.

Although many philosophers think backwards causation possible, puzzles arise when we consider worlds containing both backwards causal chains and agents capable of intervening in, and initiating, such chains. In these worlds, agents have the power to bilk, that is, the power to prevent an event from occurring which, had it occurred, would have been the cause of an earlier event. I argue, appealing to Max Black’s example and one other, that this power is absurd and hence that (...) there are no worlds containing both agents and manipulable backwards causal chains. (shrink)

In order to explain why falling barometers don't cause rain, a "no-eclipsing" requirement needs to be added to the regularity account of causation. This refinement of the regularity account allows us to see how conclusions about deterministic causes can be based on statistical premises, and thus indicates a criticism of Wesley Salmon 's "statistical relevance" account of causation. The refinement also casts some light on the problem of backwards causation.

In this paper, criticisms are made of the main tenets of Professor Mellor's argument against ‘backwards’ causation. He requires a closed causal chain of events if there is to be ‘backwards’ causation, but this condition is a metaphysical assumption which he cannot totally substantiate. Other objections to Mellor's argument concern his probabilistic analysis of causation, and the use to which he puts this analysis. In particular, his use of conditional probability inequality to establish the ‘direction’ (...) of causation is shown to be in error. 1I am indebted to Drs H. Krips, L. O'Neill and to the anonymous referee for their suggestions and critical comments on earlier drafts. (shrink)

This book provides the reader with an analysis of backward causation. The notion of backward causation faces many different paradoxes that threaten to make the notion inconsistent or incoherent. The book denies that these pose a real threat. It developed a theory of causation according to which the orientation of causation is not dependent on the direction of time. In this process it takes issues with David Lewis' contrafactual analysis of causation, and denies that the (...) direction of time is determined by irreversible processes . Likewise the book argues that the conceptual possibility of backward causation requires that the future is just as real as the past and present. Finally the book considers what the physical processes may look like if backward causation not only a a conceptual possibility but also a physical possibility. The conclusion is that no normal matter can possibly participate in backward causal processes. Instead objects moving backwards in time seem to posses negative mass and energy, a kind of objects that would be different from both ordinary objects and hypothetical tachyons. (shrink)

In order to refute the widely held belief that the game known as ‘Newcomb's paradox’ is physically nonsensical and impossible to imagine (e.g. because it involves backward causation), I tell a story in which the game is realized in a classical, deterministic universe in a physically plausible way. The predictor is a collection of beings which are by many orders of magnitude smaller than the player and which can, with their exquisite measurement techniques, observe the particles in the player's (...) body so accurately that they can predict his choice (in much the same way as we can predict the motion of celestial bodies). I argue that the player, by choosing whether to take only one box or both boxes, influences whether or not, in the past, the predictor put a million pounds into the second box. Yet, I establish that no causal paradox can arise in this set-up. (shrink)

My aim in this paper is to investigate Hegel’s relation to Spinoza’s account of teleology by discussing Spinoza and Hegel’s stance to two straightforward objections against teleological views of reality: the anthropomorphism objection and the backward causation objection. I show that both argue against a teleological account that would be committed to the anthropomorphism objection by raising the same argument: such a divine intelligence would lack what it desires to realize. I then argue that their dealing with the backward (...) causation objection differs. Whereas Spinoza finds the backward causation objection against natural purposiveness to be valid, Hegel uses this objection to build his own case: natural purposiveness obtains to a different aspect of reality than effective causality. In contrast, Spinoza defends the backward causation objection because he believes there is only one fundamental principle that reality is subject to. Not only has the issue of Spinoza and Hegel’s relationship on teleology been neglected, I also argue that such a discussion can prove illuminating with respect to Hegel’s stance to monism, as, in contrast to Spinoza, Hegel must assume that there are different fundamental principles governing reality and not merely one.

Is it a "conceptual truth" or only a logically contingent fact that, in any given kind of case, an event x which asymmetrically causes ("produces") an event y likewise temporally precedes y or at least does not temporally succeed y? A bona fide physical example in which the cause retroproduces the effect would show that backward causation is no less conceptually possible than forward causation. And it has been claimed ([9], p. 151; [4], p. 41) that in Dirac's (...) classical electrodynamics (relativistic and non-relativistic), the preacceleration of charged particles before any forces are applied to them furnishes a genuine case of retrocausation by later forces. An exposition of the pertinent physics furnishes the basis for arguing the following: Whereas the non-zero acceleration of a neutral NEWTONIAN mass particle is, of course, causally connected as such to the simultaneously applied non-zero force, the non-zero acceleration of a DIRACIAN charged particle is not causally connected at all as such to the applied forces. A fortiori, in Dirac's electrodynamics, the applied forces do not qualify asymmetrically as the causes of a non-zero acceleration as such; nor does a non-zero acceleration as such qualify as an effect produced by forces. This is shown by means of two considerations as follows: (1) In Dirac's theory, no functional dependence of the value of a non-zero acceleration on the weighted time-average of the forces is vouchsafed as a matter of physical LAW alone without any value of a constant of integration, just as no Newtonian law(s) alone can guarantee a functional dependence of the non-zero value of the velocity of a Newtonian mass particle on the applied forces. Instead, both functional dependencies alike are vouchsafed only with the crucial aid of some de facto boundary condition pertaining to either the past or to the furute, so that (2) Non-zero preaccelerations of Diracian charged particles can no more be causally attributed as such to the retrocausal action of later forces than non-zero "prevelocities" of Newtonian mass particles can be held to be caused as such by later applied forces. The retrocausal interpretation of Dirac's preaccelerations is just as invalid as the retrocausal interpretation of Newtonian prevelocities. (shrink)

Lockeans, as well as their critics, have pointed out that the memory criterion is likely to mean that none of us were ever fetuses or even infants due to the lack of direct psychological connections between then and now. But what has been overlooked is that the memory criterion leads to either backward causation and a violation of Locke’s own very plausible principle that we can have only one origin, or backward causation and a number of overlapping people (...) where we thought there was just one. I will argue that such problems cannot be avoided by replacing direct psychological connections with overlapping chains of connectedness—what has been called “psychological continuity.”. (shrink)
