The Manipulation Argument and a Kantian account of freedom

AbstractOn Kant's view, we are rational beings who are morally responsible for our actions. The main goal of this paper is to show that this Kantian view of ourselves is not undermined by the Manipulation Argument, which is currently the biggest challenge to compatibilism. To this end, I argue that a Kantian account of freedom offers a new soft‐line reply to this argument. On this Kantian account, moral responsibility requires not only positive freedom but also negative freedom. An agent is free in the positive sense just in case the agent has the rational capacity to act in compliance with moral norms. And an agent lacks negative freedom regarding their actions when these actions are determined by internal or external factors beyond their rational control. Based on this Kantian account, I provide a principled explanation of why there is a significant difference between manipulated actions and merely causally determined actions regarding moral responsibility. In addition, I bring out the distinctive characteristics of my Kantian account further by comparing it with two competing conceptions of freedom: leeway freedom and sourcehood freedom.

Freedom, moral responsibility, and the failure of universal defeat

AbstractProponents of manipulation arguments against compatibilism hold that manipulation scope (how many agents are manipulated) and manipulation type (whether the manipulator intends that an agent perform a particular action) do not impact judgments about free will and moral responsibility. Many opponents of manipulation arguments agree that manipulation scope has no impact but hold that manipulation type does. Recent work by Latham and Tierney (2022, 2023) found that people's judgments were sensitive to manipulation scope: people judged that an agent was less free and responsible when a manipulation was existential (impacting at least one but not all agents) than when the manipulation was universal (impacting every agent). This study examines people's judgements about existential and universal manipulation cases that involve both intentional and non‐intentional outcomes. We found that manipulation scope also affects people's free will and responsibility judgments in manipulation cases involving both intentional and non‐intentional outcomes. Interestingly, we also found that manipulation type influences the effect that manipulation scope has on people's free will judgments but not their moral responsibility judgments, which indicates that people's free will and responsibility judgments can come apart. This puts pressure on the prevalent assumption that judgments about free will and moral responsibility are conceptually bound together.

“Free will” is vague

AbstractThis paper argues that “free will” is vague. The argument has two steps. First, I argue that free will is a matter of degrees and, second, that there are no sharp boundaries separating free decisions and actions and non‐free ones. After presenting the argument, I focus on one significant consequence of the thesis, although others are mentioned along the way. In short, considerations of vagueness help understand the logic behind so‐called manipulation arguments, but also show why these arguments are ultimately flawed.

Manipulation, machine induction, and bypassing

A common style of argument in the literature on free will and moral responsibility is the Manipulation Argument. These tend to begin with a case of an agent in a deterministic universe who is manipulated, say, via brain surgery, into performing some action. Intuitively, this agent is not responsible for that action. Yet, since there is no relevant difference, with respect to whether an agent is responsible, between the manipulated agent and a typical agent in a deterministic universe, responsibility is not compatible with the truth of determinism. In response, some theorists have argued that there is a relevant difference, and have developed two sorts of accounts of that difference: bypassing views, and manipulator-focused views. Manipulator-focused views suggest that the difference concerns the presence of a manipulator, whereas bypassing views suggest that the relevant difference concerns the fact that the action issues from attitudes that the manipulated agent acquired in a way that bypassed her capacities for control over her mental life. One sort of case used to decide between these sorts of accounts is a case of machine induction, which is just like a manipulation case, yet the change in the agent is the result of some natural force. Against the received view, Xiaofei Liu argues that such cases pose problems for bypassing views, and favor manipulator-focused views instead. This paper addresses Liu’s arguments, as well as a variety of cases, concluding that cases of machine induction do not provide motivation for a bypassing theorist to adopt a manipulator-focused view.

Why causal facts matter: a critique of Jeppsson’s hard-line reply to four-case manipulation arguments

ABSTRACT This paper poses a series of objections to Sofia Jeppsson’s hard-line reply to Pereboom’s four-case manipulation argument. According to Jeppsson, the compatibilist can resist Pereboom’s argument by disregarding facts about what caused an agent to act (the ‘causal perspective’) and focusing primarily on the agent’s own perspective of their action (the ‘agential perspective’). Jeppsson argues that we have an obligation to disregard the causal perspective. This is for two reasons: (I) we must disregard the causal facts of the agent’s action, including whether they have been manipulated, since the agent has reason to disregard them; and (II) the causal perspective is not obviously relevant to judgments of moral responsibility. In this paper, I show that both (I) and (II) can be undermined because the causal perspective provides information that is necessary for moral deliberations. This is because it would seem that at least one necessary condition for an agent to be considered morally responsible is that the agent’s actions are not fully controlled by someone else. Since this is information that we can only obtain via the causal perspective, we do not have an obligation to disregard this perspective and so need not accept the compatibilist’s hard-line account.

Why the manipulation argument fails: determinism does not entail perfect prediction

Determinism is frequently understood as implying the possibility of perfect prediction. This possibility then functions as an assumption in the Manipulation Argument for the incompatibility of free will and determinism. Yet this assumption is mistaken. As a result, arguments that rely on it fail to show that determinism would rule out human free will. We explain why determinism does not imply the possibility of perfect prediction in any world with laws of nature like ours, since it would be impossible for an agent to predict with certainty any future event that is causally influenced by events outside her own backward light cone yet inside the backward light cone of the future event. This is the light-cone limit and it undermines the Manipulation Argument or limits what this argument can tell us about the relevance of determinism to free will. We also respond to objections that the light-cone limit is irrelevant to the Manipulation Argument.

Defusing Existential and Universal Threats to Compatibilism

Many manipulation arguments against compatibilism rely on the claim that manipulation is relevantly similar to determinism. But we argue that manipulation is nothing like determinism in one relevant respect. Determinism is a "universal" phenomenon: its scope includes every feature of the universe. But manipulation arguments feature cases where an agent is the only manipulated individual in her universe. Call manipulation whose scope includes at least one but not all agents "existential manipulation." Our responsibility practices are impacted in different ways by universal and existential phenomena. And this is a relevant difference, especially on Strawsonian approaches to moral responsibility, which take facts about our responsibility practices to be deeply connected to the nature of responsibility itself. We argue that Strawsonian accounts of moral responsibility are immune to manipulation arguments, and no attempt to modify the scope of manipulation or determinism featured in these arguments will help incompatibilists secure their desired conclusion.

An Argument against the Methodology of the Manipulation Argument

Manipulation and Machine Induction

Abstract One type of soft-line reply to manipulation arguments, which I call ‘the another-agent reply’, focuses on the existence of some controlling agent(s) and how this can undermine the actor's moral responsibility. A well-known challenge to this type of reply is the so-called ‘machine induction’ case. This paper provides an argument for why ‘machine induction’ presents no real challenge to the another-agent reply. It further argues that any soft-liner who does not leave room for the existence of some controlling agent(s) in their explanation of why manipulation undermines responsibility will face a dilemma. Thus, instead of presenting a challenge to the another-agent reply, ‘machine induction’ actually presents a reason in support of it.

The U.S.–China trade imbalance and the theory of free trade: debunking the currency manipulation argument

ABSTRACT The U.S.–China trade imbalance is commonly attributed to a Chinese policy of currency manipulation. However, empirical studies failed to reach consensus on the RMB misalignment. We argue that this is not a consequence of poor measurement but of theory. At the most abstract level the conventional principle of comparative cost advantage suggests real exchange rates will adjust so as to balance trade. Therefore, the persistence of trade imbalances tends to be interpreted as arising from currency manipulation facilitated by foreign exchange interventions. By way of contrast, the absolute cost theory explains trade imbalances as the outcome of free trade among nations that have unequal real costs. We argue that a disparity in real costs is the root cause of the U.S.–China trade imbalance.

On the Compatibility of Rational Deliberation and Determinism: Why Deterministic Manipulation Is Not a Counterexample

Abstract This paper aims to defend deliberation-compatibilism against several objections, including a recent counterexample by Yishai Cohen that involves a deliberator who believes that whichever action she performs will be the result of deterministic manipulation. It begins by offering a Moorean-style proof of deliberation-compatibilism. It then turns to the leading argument for deliberation-incompatibilism, which is based on the presumed incompatibility of causal determinism and the ‘openness’ required for rational deliberation. The paper explains why this argument fails and develops a coherent account of how one can rationally deliberate and believe in causal determinism without inconsistency. The second half of the paper then takes up Cohen's proposed counterexample and his Four-Case Deliberation Argument (FCDA) against deliberation-compatibilism, which is meant to mirror Derk Pereboom's famous Four-Case Manipulation Argument. In response, the author defends a hard-line reply to FCDA but also argues that the notion of ‘sourcehood’ relevant to rational deliberation differs from that involved in free will.

Manipulation Arguments and Libertarian Accounts of Free Will

AbstractIn response to the increasingly popular manipulation argument against compatibilism, some have argued that libertarian accounts of free will are vulnerable to parallel manipulation arguments, and thus manipulation is not uniquely problematic for compatibilists. The main aim of this article is to give this point a more detailed development than it has previously received. Prior attempts to make this point have targeted particular libertarian accounts but cannot be generalized. By contrast, I provide an appropriately modified manipulation that targets all libertarian accounts of freedom and responsibility—an especially tricky task given that libertarian accounts are a motley set. I conclude that if manipulation arguments reveal any theoretical cost then it is one borne by all accounts according to which we are free and responsible, not by compatibilism in particular.

The manipulation argument and Frankfurt-style compatibilism

In the metaphysics of free will, the most intense debate at this time is that between Frankfurt-style compatibilists and proponents of the manipulation argument centred around the appropriate answer to the question of whether a compatibilisticaly defined agents can be morally responsible if they are a victim of manipulation? In this paper, I aim to explain the reasons behind the dispute as well as bring attention to certain tacit assumptions that underpin the concept of the manipulation argument and that Frankfurt-style compatibilists need to reject. For this reason, my conclusions is that Frankfurt-style compatibilists must accept the counter-intuitive possibility that agents can have moral responsibility for their actions despite being a victim of manipulation.

The agential perspective: a hard-line reply to the four-case manipulation argument

One of the most influential arguments against compatibilism is Derk Pereboom’s four-case manipulation argument. Professor Plum, the main character of the thought experiment, is manipulated into doing what he does; he therefore supposedly lacks moral responsibility for his action. Since he is arguably analogous to an ordinary agent under determinism, Pereboom concludes that ordinary determined agents lack moral responsibility as well. I offer a hard-line reply to this argument, that is, a reply which denies that this kind of manipulation is responsibility undermining. I point out that fully fleshed-out manipulated characters in fiction can seem morally responsible for what they do. This is plausibly because we identify with such characters, and therefore focus on their options and the reasons for which they act rather than the manipulation. I further argue that we ought to focus this way when interacting with other agents. We have no reason to trust the incompatibilist intuitions that arise when we regard manipulated agents from a much more detached perspective.

Self-Defense, Deterrence, and the Use Objection: A Comment on Victor Tadros’s Wrongs and Crimes

In Wrongs and Crimes, Victor Tadros argues that wrongdoers acquire special duties to those they’ve wronged, and from there he generates wrongdoers’ duties to contribute to general deterrence by being punished. In support, he contends that my manipulation argument against compatibilism fails to show that causal determination is incompatible with the proposed duties wrongdoers owe to those they’ve wronged. I respond that I did not intend my manipulation argument to rule out a sense of moral responsibility that features such duties, and that I don’t believe it does. In fact, I’m willing to accept a restricted version of Tadros’s proposal, and I explain how this addition modifies the self-defense-based position on deterrence that I’ve defended in the past.

Desperately seeking sourcehood

In a recent essay, Deery and Nahmias (Philos Stud 174(5):1255–1276, 2017) utilize interventionism about causation to develop an account of causal sourcehood in order to defend compatibilism about free will and moral responsibility from manipulation arguments. In this paper, we criticize Deery and Nahmias’s analysis of sourcehood by drawing a distinction between two forms of causal invariance that can come into conflict on their account. We conclude that any attempt to resolve this conflict will either result in counterintuitive attributions of moral responsibility or will undermine their response to manipulation arguments.

Double Defence Against Multiple Case Manipulation Arguments

The article aims to show that compatibilism can be defended against Pereboom’s ‘Four Case’ Manipulation Argument (Pereboom 2001), hereinafter referred to as 4-Case MA, by combining the soft-line and the hard-line replies. In the first section, I argue that the original version of the 4-Case MA was refuted by the soft-line reply, but Pereboom’s (2014) modified version of the argument can’t be refuted this way. In the second section, I analyse McKenna’s hard-line reply to the original Pereboom’s 4-Case MA and argue that it wasn’t completely successful. In section three, I present five new Pereboom-style cases. In section four, I argue that these new cases constitute a combination of the soft-line and hard-line defence against Pereboom’s modified multiple case manipulation argument.

Manipulators and Moral Standing

Manipulation arguments aim to show that compatibilism is false. Usually, they aim to undermine compatibilism by first eliciting the intuition that a manipulated agent is not morally responsible. Todd’s (Philosophers’ Imprint, 12(7): 1–18, 2012) Moral Standing Manipulation Argument instead aims to first elicit the intuition that a manipulator cannot blame her victim. Todd then argues that the best explanation for why a manipulator cannot blame her victim is that incompatibilism is true. In this paper, I present three lines of defence against this argument for those who agree a manipulator cannot blame her victim.

Manipulation and Degrees of Blameworthiness

We propose an original response to Derk Pereboom’s four-case manipulation argument. This response combines a hard-line and a soft-line. Like hard-liners, we insist that the manipulated agent is blameworthy for his wrongdoing. However, like soft-liners, we maintain that there is a difference in blameworthiness between the manipulated agent and the non-manipulated one. The former is less blameworthy than the latter. This difference is due to the fact that it is more difficult for the manipulated agent to do the right thing. We explain how we can make sense of this notion of difficulty in terms of Fischer and Ravizza’s notion of reasons-responsiveness.
