1. Introduction

You probably shouldn’t steal. Common sense tells us that stealing is wrong. But sometimes stealing seems less wrong, or not wrong at all, after we discover the cause of the stealing behavior. For example, if the fact that your family is starving causes you to steal a loaf of bread, many would say that you are not as blameworthy as someone who steals out of greed or spite. And imagine a kleptomaniac who cannot control her stealing behavior. We probably shouldn’t blame her for those actions (though we might encourage her to consult a therapist about her condition).

But why shouldn’t we blame the kleptomaniac? That is to say, how are we justified in holding the kleptomaniac morally responsible? One good reason not to blame the kleptomaniac is that she cannot help her behavior. She possesses a psychological problem that is out of her control. That’s why some defendants are acquitted on grounds of insanity. If you are not in control of your actions, you are not responsible for those actions.

But what if every one of our actions is actually out of our control. That is, what if only seems as if we have the freedom to choose between actions, but we are in fact as undeserving of blame as, say, the severely mentally ill?

There are many philosophically interesting answers to this question, and they deal with some famous and famously difficult problems surrounding the concept of free will. The concept of free will brings with it the idea that at least some of our choices are ours alone—we are fully in control of them, and therefore we are fully responsible for them. Free will is the basis for moral responsibility, or so many have argued.

Philosophers commonly say that ‘ought’ implies ‘can.’ So what does this mean? To justifiably tell someone that she (morally) ought to do something, it would also have to be the case that she can do that thing. Suppose I tell you that you ought to cure cancer. If you did cure cancer, you could prevent large amounts of suffering and many premature deaths. It would be a really good thing. Nonetheless, given that, in all likelihood, it would be impossible for you to cure cancer, it seems absurd to say that you have a moral responsibility to do so, or that you ought to. Importantly, then, you are not blameworthy for your failure to cure cancer. It seems that we are only justified in blaming (or praising) people for their actions—or believing that they are responsible for their actions—when they are able to freelychoose one action over others. But as we have seen, this freedom is the subject of extensive philosophical analysis, and our everyday sense of moral responsibility hangs in the balance.1

2. Libertarian Free Will

Those who claim that we have libertarian free will argue that we make free choices when it is possible that we could have done otherwise.2 When this condition obtains, we are justified in blaming (or praising) the person who made the choice. That is, we are justified in holding that person morally responsible for the action. The idea that we possess free will has a lot of intuitive force behind it, but philosophers have struggled with the question of what could allow for free will in the face of concerns about the causal laws of the world.

3. Determinism

The determinist appeals to the causal laws of the world in order to challenge the claim that we have free will. Everything that happens can be fully explained by the causal history of what happened before. Though it seems as if we have choices, it is always the case that, for any choice we are faced with, only one of the seemingly available paths will ultimately be taken, and the other paths were never truly available.3 To suggest that we have free will is to suggest that we are somehow outside of and unaffected by the causal chain of events—that we can be the sole source of our actions—but the determinist argues that this is unsupported by facts about how the world works.4

3. Compatibilism

The determinist may then find this to be proof that moral responsibility is an illusion, or she may attempt to retain a viable sense of moral responsibility in the face of determinism. Compatibilists argue for the latter. They claim that determinism and moral responsibility are actually compatible.5 By appealing to claims about an agent’s internal state, the compatibilist will argue that agents can be held responsible when they are acting according to certain sort of disposition. And others have pointed out that we still have strong intuitions of responsibility even about cases that are explicitly deterministic.6

4. Revisionism/Illusionism

The power of these intuitions of responsibility cause some determinists to argue for a revisionist approach. They accept that appeals to moral responsibility are theoretically unjustified, but they nonetheless assert that we are pragmatically justified in accepting the illusion that people actually have moral responsibility, because practices of praising and blaming are still useful, and abandoning them could lead to chaos.7

5. Incompatibilism

Finally, there are those who maintain that determinism and moral responsibility are utterly incompatible. Importantly, both determinists and libertarians about free will may hold this view. The libertarian can then tout this incompatibility as a virtue of his view. If the two really are incompatible, then only libertarian free will allows us to retain our very commonsense intuitions of moral responsibility.8 The hard determinist will bite the bullet and claim that, if the two really are incompatible, then we are being intellectually dishonest by maintaining practices of moral responsibility, given that we can always trace the causes of an action to something that is ultimately fully outside of the control of the agent.9

This is an ancient philosophical problem that has given rise to an expanding and ever more nuanced set of views. But we can all agree that anyone who grapples with the problem of free will must also take seriously questions of moral responsibility.

not free. Of course, quantum mechanics is only concerned with the smallest scales of reality, and atthe macro scale we are familiar with the orderly progress of causal determinism still makes sense.For example, although atomic decay is inherently unpredictable, given a large enough number of particles the average rate of decay can be calculated  this is what is known as the half-life of anelement. The human body operates on a scale high above quantum mechanical interactions, and soto establish whether humans are exempt from the deterministic laws that govern other large bodiesrequires a different kind of investigation.The psychologist Benjamin Libet conducted experiments on human subjects to test exactly when it isthat we become consciously aware of willing to do an action (Libet, 1999). His aim was to discover if we are consciously in control of the biological processes which lead to our actions, specifically thosewhich lead to muscle movements. He found that readiness potential  the electrical build-up in thebrains motor region which precedes a muscle movement  begins to increase 350-400ms before aperson actually reports being aware of the intention to act. He concluded that human volitions, atleast with regard to movement, are initiated unconsciously. He argues that this does not precludeconscious control over actions as long as we can prevent ourselves from doing things 50ms beforethey occur, so our freedom could be a kind of vetoing power. However, this hardly fits with ournormal view of freedom  we do not see ourselves as unpredictable machines, waiting for volitionsto appear and then deciding in less than a fifth of a second whether or not to go through with it. Wehave a distinct feeling that our own conscious mind and will are the actuators of our movements andthe source of our thoughts.One of the philosophical cases against freedom is raised by Daniel Wegner. He argues that our senseof having a free will is an illusion. He makes a distinction between the experience of consciouslywilling an action and the actual causation of the action. The tendency to confuse them, he says, isthe source of the illusion of conscious will (Wegner,


004). He builds on a Humean thesis whichstates that our experience of willing an action is mistakenly thought to be the cause of our deliberateactions because it always occurs in causal conjunction with them. We have a natural propensity toinfer rational principles from empirical experiences, and the experience of two things alwaysoccurring in conjunction makes us assume there is a causal relation between them. However, this isnot a rationally qualified inference, and Libets experiments suggest that our assumption that ourdeliberate actions are caused by our conscious volitions is a mistake.There are strong reasons to be worried about the determinist thesis, however, since it seems tothreaten the commonplace notions of personal accountability and self-control which are central tomany of our moral practices such as blame and punishment. For this reason there are many thinkerswho have argued against determinism in favour of human liberty of indifference. Jean-Paul Sartre,for example, argued that agents are consciously responsible for the constraints they place onthemselves by failing to render past resolutions effective  for example, a person with a gamblingaddiction is fully responsible for whether or not they will fulfil their past resolutions to stopgambling. It is by our own conscious willing that we allow our circumstances to constrain us.However, one might argue that determinism does not threaten ordinary moral concepts andpractices. In fact, it is even possible to argue that determinism is


to make morality arealistic idea. To elaborate, if we imagine that people were in fact free agents who could actindependently of causes, they would be inherently unpredictable. The ordinary practices of praise
