Indeterminists reject which premise of the following argument

Determinism is a thesis about the statements or propositions that are the laws of our world; it says nothing about whether these statements or propositions are knowable by finite beings, let alone whether they could, even in principle, be used to predict all future events. For more on the relation between determinism and predictability, see the Encyclopedia entry on Causal Determinism. Lewis ; Earman ; Loewer a; Beebee ; Schaffer to various kinds of necessitarian accounts S. Shoemaker ; Armstrong ; Carroll For critique, see Mackie a and Franklin Determinism understood according to either of the two definitions above is not a thesis about causation; it is not the thesis that causation is always a relation between events, and it is not the thesis that every event has a cause.

It is now generally accepted that it might be true that every event has a cause even though determinism is false and thus some events lack sufficient or deterministic causes. More controversially, it might be true that every event has a cause even if our world is neither deterministic nor probabilistic. If there can be causes without laws if a particular event, object, or person can be a cause, for instance, without instantiating a law , then it might be true, even at a lawless or partly lawless world, that every event has a cause Anscombe ; van Inwagen Whether it does depends on what the correct theory of causation is; in particular, it depends on what the correct theory says about the relation between causation and law.

What is clear, however, is that we should not make the assumption, almost universally made in the older literature, that the thesis that every event has a cause is equivalent to the thesis of determinism. This is an important point, because some of the older arguments in the literature against incompatibilism assume that the two claims are equivalent Hobart In the older literature, it was assumed that determinism is the working hypothesis of science, and that to reject determinism is to be against science.

This no longer seems plausible. Some people think that quantum physics has shown determinism to be false. This remains controversial Albert ; Loewer b; P.

Lewis , but it is now generally agreed that we can reject determinism without accepting the view that the behavior of human beings falls outside the scope of natural laws. If naturalism is the thesis that human behavior can be explained in the same kind of way—in terms of events, natural processes, and laws of nature—as everything else in the universe, then we can reject determinism without rejecting naturalism. Note, finally, that determinism neither entails physicalism nor is entailed by it.

There are possible worlds where determinism is true and physicalism false; e. And there are possible worlds perhaps our own where physicalism is true and determinism is false. So much for determinism. What about free will? How should we understand the disagreement between the compatibilist and the incompatibilist? Are we born with free will?

If not, when do we acquire it, and in virtue of what abilities or powers do we have it? What is the difference between acting intentionally and acting with free will? The free will thesis is a minimal claim about free will; it would be true if one person in the universe acted with free will acted freely, acted while possessing free will on one occasion. Since non-determinism is the negation of determinism, and since determinism is a contingent thesis, we can divide the set of possible worlds into two non-overlapping subsets: deterministic worlds and non-deterministic worlds.

Given this apparatus, we could define incompatibilism and compatibilism in the following way: incompatibilism is the thesis that no deterministic world is a free will world. Equivalently, incompatibilism is the claim that necessarily, if determinism is true, then the free will thesis is false. And we could define compatibilism as the denial of incompatibilism; that is, as the claim that some deterministic worlds are free will worlds.

Equivalently, compatibilism is the claim that possibly, determinism and the free will thesis are both true. This way of defining compatibilism is unproblematic. There are compatibilists who are agnostic about the truth or falsity of determinism, so a compatibilist need not be a soft determinist someone who believes that it is in fact the case that determinism is true and we have free will. But all compatibilists believe that it is at least possible that determinism is true and we have free will.

So all compatibilists are committed to the claim that there are deterministic worlds that are free will worlds. But this definition of incompatibilism has a surprising consequence. Suppose, as some philosophers have argued, that we lack free will because free will is conceptually or metaphysically impossible, at least for nongodlike creatures like us Taylor , []; G. Strawson , If these philosophers are right, there are no free will worlds.

And if there are no free will worlds, it follows that there are no deterministic free will worlds. So if free will is conceptually or metaphysically impossible, at least for creatures like us, it follows that incompatibilism as we have just defined it is true. If it is conceptually or metaphysically impossible for us to have free will, then we lack free will regardless of whether determinism is true or false.

And if that is so, then the incompatibilist cannot say the kind of things she has traditionally wanted to say: that the truth or falsity of determinism is relevant to the question of whether or not we have free will, that if determinism were true, then we would lack free will because determinism is true, and so on.

If we want to avoid this counter-intuitive result, there is a remedy. Instead of understanding compatibilism and incompatibilism as propositions that are contradictories, we can understand them as propositions that are contraries.

Compatibilism and incompatibilism are both false if a third claim, impossibilism, is true. Impossibilism is the thesis that free will is conceptually or metaphysically impossible for non-godlike creatures like us. If we accept this three-fold classification, we can define our terms as follows: Impossibilism is the thesis that there are no free will worlds. Incompatibilism is the thesis that there are free will worlds but no deterministic world is a free will world.

Compatibilism is the thesis that there are free will worlds and free will worlds include deterministic worlds. For some objections to this three-fold classification see McKenna and Mickelson a.

For defense, see Vihvelin and Theorists who defend impossibilism include Double , G. Strawson and , and Smilansky Another kind of impossibilist is the fatalist Taylor , []. In the older literature, there were just two kinds of incompatibilists—hard determinists and libertarians. A hard determinist is an incompatibilist who believes that determinism is in fact true or, perhaps, that it is close enough to being true so far as we are concerned, in the ways relevant to free will and because of this we lack free will Holbach ; Wegner A libertarian is an incompatibilist who believes that we in fact have free will and this entails that determinism is false, in the right kind of way van Inwagen But in the contemporary literature there are incompatibilists who avoid such risky metaphysical claims by arguing that free will is possible at worlds where some of our actions have indeterministic event causes Kane , , , , a; Ekstrom ; Balaguer or that free will is possible at worlds where some of our actions are uncaused Ginet Note that none of these three kinds of incompatibilists agent-causation theorists, indeterministic event-causation theorists, non-causal theorists need be libertarians.

They may reserve judgment about the truth or falsity of determinism and therefore reserve judgment about whether or not we in fact have free will. They might also be hard determinists because they believe that determinism is in fact true. But what they do believe—what makes them incompatibilists—is that it is possible for us to have free will and that our having free will depends on a contingent fact about the laws that govern the universe: that they are indeterministic in the right kind of way see the entry on incompatibilist theories of free will.

Given these definitions and distinctions, we can now take the first step towards clarifying the disagreement between compatibilists and incompatibilists. Both sides agree that it is conceptually and metaphysically possible for us to have free will; their disagreement is about whether any of the possible worlds where we have free will are deterministic worlds.

Arguments for incompatibilism must, then, be arguments for the claim that necessarily, if determinism is true, we lack the free will we might otherwise have.

It is easy to think that determinism implies that we have a destiny or fate that we cannot avoid, no matter what we choose or decide and no matter how hard we try. Man, when running over, frequently without his own knowledge, frequently in spite of himself, the route which nature has marked out for him, resembles a swimmer who is obliged to follow the current that carries him along; he believes himself a free agent because he sometimes consents, sometimes does not consent, to glide with the stream, which, notwithstanding, always hurries him forward.

Holbach []: ; see also Wegner It is widely agreed, by incompatibilists as well as compatibilists, that this is a mistake. But these threats to free will have nothing to do with determinism. Determinism is consistent with the fact that our deliberation, choices and efforts are part of the causal process whereby our bodies move and cause further effects in the world. Putting aside this worry, we may classify arguments for incompatibilism as falling into one of two main varieties:.

Someone who argues for incompatibilism in this way may concede that the truth of determinism is consistent with the causal efficacy of our deliberation, choices, and attempts to act. But, she insists, determinism implies that the only sense in which we are responsible for what we do is the sense in which a dog or young child is responsible. Moral responsibility requires something more than this, she believes. Moral responsibility requires autonomy or self-determination: that our actions are caused and controlled by, and only by , our selves.

To use a slogan popular in the literature: We act freely and are morally responsible only if we are the ultimate source of our actions. Each of us, when we act, is a prime mover unmoved. In doing what we do, we cause certain events to happen, and nothing—or no one—causes us to cause these events to happen. Chisholm Free will…is the power of agents to be the ultimate creators or originators and sustainers of their own ends or purposes…when we trace the causal or explanatory chains of action back to their sources in the purposes of free agents, these causal chains must come to an end or terminate in the willings choices, decisions, or efforts of the agents, which cause or bring about their purposes.

Kane 4. Arguments of the second kind focus on the notion of choice. To have a choice, it seems, is to have genuine options or alternatives—different ways in which we can act. The worry is that determinism entails that what we do is, always, the only thing we can do, and that because of this we never really have a choice about anything , as opposed to being under the perhaps inescapable illusion that we have a choice.

Someone who argues for incompatibilism in this way may concede that the truth of determinism is consistent with our making choices, at least in the sense in which a dog or young child makes choices, and consistent also with our choices being causally effective. But, she insists, this is not enough for free will; we have free will only if we have a genuine choice about what actions we perform, and we have a genuine choice only if there is more than one action we are able to perform.

A person has free will if he is often in positions like these: he must now speak or be silent, and he can now speak and can now remain silent; he must attempt to rescue a drowning child or else go for help, and he is able to attempt to rescue the child and able to go for help; he must now resign his chairmanship or else lie to the members; and he has it within his power to resign and he has it within his power to lie. Our choices include choices among purely mental actions to pay attention to a lecture or to spend the time deciding what to cook for dinner as well as choices about the actions we perform by moving our bodies.

We might question whether arguments based on self-determination and arguments based on choice are independent ways of arguing for incompatibilism for the following reason: I cause and control my actions in the self-determining way required for moral responsibility only if my actions are the product of my free will and my actions are the product of my free will only if I have the ability to do choose to do, decide to do, intend to do, try to do otherwise.

If determinism has the consequence that I never have the ability to do otherwise, it also has the consequence that I never cause my actions in the self-determining way required for moral responsibility Kane At one time, this link between moral responsibility, self-determination, and the ability to do otherwise was common ground between compatibilists and incompatibilists.

That is, everyone agreed that a person is morally responsible only if she has the right kind of control over what she does, and everyone assumed that a person has the right kind of control over something she does only if she is able to do or at least decide, choose, intend, or try otherwise.

Given this assumption, anyone hoping to defend the claim that moral responsibility is compatible with determinism had to first show that the ability to do otherwise is compatible with determinism. This debate was crippled by the fact that it took place at a time when counterfactuals were still poorly understood, before the advent of the Lewis-Stalnaker possible worlds semantics D.

Lewis For argument that this pessimism was premature, see Vihvelin and Frankfurt wanted to defend the claim that moral responsibility is compatible with determinism without having to defend the claim that the ability to do otherwise is compatible with determinism.

His strategy took the form of an ingenious thought experiment that was supposed to show that no matter how you understand ability to do otherwise—whether you are a compatibilist or an incompatibilist—you should agree that the possession of this ability is not a necessary condition of being morally responsible Frankfurt There were two steps to the thought experiment. In the first step he invited you to imagine a person, Jones, who has free will, and who acts freely and who satisfies all the conditions you think necessary and sufficient for moral responsibility.

You may imagine Jones in one of the scenarios van Inwagen describes, faced with a choice to speak or be silent, to try to rescue the child or go for help, to resign his chairmanship or to lie, and to imagine that Jones deliberates and decides, for his own reasons, in favor of one of his contemplated alternatives, and then successfully acts on his decision.

In the second step you are invited to add to the story the existence of a powerful being, Black, who takes a great interest in what Jones does, including how he deliberates and decides. You may fill in the details however you like, but you must imagine that Black has the power to interfere with Jones in a way that ensures that Jones does exactly what Black wants him to do.

By lucky co-incidence, Jones did exactly what Black wanted him to do. He even deliberated and decided the way Black wanted him to deliberate and decide.

So Black remained on the sidelines and only watched. Because Black never laid a finger on Jones, or interfered in any way, it seems that Jones is as morally responsible in the second step of the story as he is in the first step.

How can Black, sitting on the sidelines, deprive Jones of the ability to deliberate, decide, or try otherwise? But Black never exercises his power. There is a difference between the existence of a power and the exercise of a power. The truth about Jones is not that Black robs him of the ability to do otherwise; it is the more complicated truth that Black puts him at constant risk of losing the ability to do otherwise.

His thought experiment was a failure; while most compatibilists were convinced, most incompatibilists were not. Compatibilists who were not convinced include Smith , ; Campbell ; Fara ; Vihvelin These incompatibilists insisted, though not for the reason given above, that Black does not succeed in robbing Jones of all his freedom; there is something that remains up to Jones Widerker ; Ginet ; Kane The critics of the argument rejected this charge, arguing that Jones retains a morally relevant ability to do otherwise, thus resurrecting the very debate that Frankfurt had hoped to undermine.

But there has been a cost. Our interest in free will is not limited to our interest in moral responsibility. The literature on the traditional problem of free will and determinism is dominated by incompatibilists. There is a growing consensus that the incompatibilist is right: if our universe is a deterministic one, we never have the ability to choose and do anything other than what we actually do. Before we ask whether this pessimism about the compatibility of free will with determinism is warranted, we should pause to ask whether there really is a substantive disagreement between compatibilists and incompatibilists.

When an incompatibilist says that determinism would rob us of the free will we think we have, including genuine choices and the ability to do otherwise, and when the compatibilist denies this, are they asserting and denying the same proposition?

Or is the incompatibilist asserting one thing while the compatibilist is denying something else? Some of the things said in the literature suggest that there is no substantive debate.

And one leading semantic proposal might seem to support the claim that there is no real dispute. Lewis , Kratzer For a different kind of contextualist proposal see Hawthorne ; for criticism, see Feldman So the proposition denied by the incompatibilist is not the proposition asserted by the compatibilist.

The debate, he says, is about whether determinism has the consequence that no one is ever able to do otherwise equivalently, that no one ever has it in their power to do otherwise given what ordinary speakers mean, in the contexts in which they use these words.

The contexts to which he is referring are the contexts of deliberation and choice in which we consider our options, while believing that we are able to pursue each of them. The proposition asserted by the compatibilist is the proposition denied by the incompatibilist. Citing David Lewis as his example of a compatibilist opponent, van Inwagen says that he and Lewis cannot both be right.

One of them is wrong, but neither is muddled or making a simple mistake van Inwagen In what follows, we will assume that the debate about free will including, but not necessarily limited to, genuine choice and the ability to do otherwise and determinism is a substantive debate, and not one that can be dissolved by appeal to different senses or contexts of utterance.

We will now turn to the arguments. These are arguments that appeal primarily to our intuitions. There are many variations on this way of arguing for incompatibilism, but the basic structure of the argument is usually something like this:.

If determinism is true, we are like: billiard balls, windup toys, playthings of external forces, puppets, robots, victims of a nefarious neurosurgeon who controls us by directly manipulating the brain states that are the immediate causes of our actions. Billiard balls windup toys, etc.

Most of these intuition-based arguments are not very good. Billiard balls, toys, puppets, and simple robots lack minds, and having a mind is a necessary condition of having free will. For discussion of cases involving more subtle kinds of manipulation, see Section 3. The No Forking Paths argument van Inwagen ; Fischer ; Ekstrom begins by appealing to the idea that whenever we make a choice we are doing or think we are doing something like what a traveler does when faced with a choice between different roads.

The only roads the traveler is able to choose are roads which are a continuation of the road she is already on. By analogy, the only choices we are able to make are choices which are a continuation of the actual past and consistent with the laws of nature. But if determinism is true, then our journey through life is like traveling in one direction only on a road which has no branches.

There are other roads, leading to other destinations; if we could get to one of these other roads, we could reach a different destination. So if determinism is true, our actual future is our only possible future ; we are never able to choose or do anything other than what we actually do.

But several crucial assumptions have been smuggled into this picture: assumptions about time and causation and assumptions about possibility.

These assumptions are all controversial; on some theories of time and causation the four-dimensionalist theory of time, a theory of causation that permits time travel and backwards causation , they are all false D.

Lewis ; Horwich ; Sider ; Hoefer The assumption about possibility is that possible worlds are concrete spatio-temporal things in the way that roads are and that worlds can overlap literally share a common part in the way that roads can overlap.

But most possible worlds theorists reject the first assumption and nearly everyone rejects the second assumption Adams ; D. T Multiple Choice Correct answers are marked with an asterisk. John Locke.

A primary reason for concern over this question relates to moral responsibility. If we cannot make free choices, how can we be held accountable for our actions? We will consider moral actions in depth in the next module, on Ethics. For now, keep in mind that there is a lot stake as we look at the issue of free will.

Determinism is the view that all things are determined by antecedent prior conditions. Everything physical is bound by the laws of cause and effect. Every event, including human actions , is brought about by previous events in accordance with universal causal laws that govern the world.

A supplemental resource bottom of page explores the distinction between determinism and predictability. Indeterminism holds that some events, including human actions, are not necessarily determined by previous events in accordance with universal causal laws. Some indeterminist theories assert the possibility of free will. There are also indeterminist theories related to other disciplines with metaphysical import, for example, in physics with regard to the behavior of micro-particles.

Libertarianism is an indeterminist theory about the possibility of free will. Libertarianism is the view that humans do have free will and make genuinely free choices, and that when humans make a choice, they could have chosen alternatively. If you are a libertarian, then are you are an indeterminist; but if you are an indeterminist, you are not necessarily a libertarian.

Compatibilism is the view that determinism does not rule out what is meant by free will, even though determinism is real and all events are caused. In general, compatibilists assert that we can consider human actions free in that they are internally and consciously motivated by our desires, rather than caused by external influences or constraints.

We will examine one compatibilist philosopher later in this topic. Thus man is a being purely physical; in whatever manner he is considered, he is connected to universal Nature: submitted to the necessary, to the immutable laws that she imposes on all the beings she contains, according to their peculiar essences; conformable to the respective properties with which, without consulting them, she endows each particular species.

Humans are incapable of acting as free agents, it would be unnatural, and impossible. Humans cannot be both part of nature and outside of nature. As a part, subordinate to the great whole, man is obliged to experience its influence. To be a free agent it were needful that each individual was of greater strength than the entire of Nature; or, that he was out of this Nature: who, always in action herself, obliges all the beings she embraces, to act, and to concur to her general motion….

In short, man would be an unnatural being; totally incapable of acting in the manner we behold. In effect we are products of our experiences, we remember and act accordingly. The will, as we have elsewhere said, is a modification of the brain, by which it is disposed to action or prepared to give play to the organs. This will is necessarily determined by the qualities, good or bad, agreeable or painful, of the object or the motive that acts upon his senses; or of which the idea remains with him, and is resuscitated by his memory.

In consequence, he acts necessarily; his action is the result of the impulse he receives either from the motive, from the object, or from the idea, which has modified his brain, or disposed his will.

Such experiences include exposure to new ideas. Still it is the brain that is modified which in turn effects the new disposition. When he does not act according to this impulse, it is because there comes some new cause, some new motive, some new idea, which modifies his brain in a different manner, gives him a new impulse, determines his will in another way; by which the action of the former impulse is suspended: thus, the sight of an agreeable object, or its idea, determines his will to set him in action to procure it; but if a new object or a new idea more powerfully attracts him, it gives a new direction to his will, annihilates the effect of the former, and prevents the action by which it was to be procured.

Man is said to deliberate when the action of the will is suspended; this happens when two opposite motives act alternately upon him. To deliberate, is to hate and to love in succession; it is to be alternately attracted and repelled; it is to be moved sometimes by one motive, sometimes by another.

Man only deliberates when he does not distinctly understand the quality of the objects from which he receives impulse, or when experience has not sufficiently apprised him of the effects, more or less remote, which his actions will produce…. When the soul is assailed by two motives that act alternately upon it, or modify it successively, it deliberates; the brain is in a sort of equilibrium, accompanied with perpetual oscillations, sometimes towards one object, sometimes towards the other, until the most forcible carries the point, and thereby extricates it, from this state of suspense, in which consists the indecision of his will.

Choice is an illusion.
