Elbow Room: The Varieties of Free Will Worth Wanting is a 1984 book by the American philosopher Daniel Dennett, in which Dennett discusses the philosophical issues of free will and determinism.

Contents

In 1983, Dennett delivered the John Locke Lectures at Oxford on the topic of free will. In 1984, these ideas were published in the book Elbow Room: The Varieties of Free Will Worth Wanting. In this book Daniel Dennett explored what it means for people to have free will. The title, Elbow Room, is a reference to the question: "Are we deterministic machines with no real freedom of action or do we in fact have some elbow room, some real choice in our behavior?".

Synopsis

Determinism does not make humans equivalent to animals

A major task taken on by Dennett in Elbow Room is to clearly describe just what people are as biological entities and why they find the issue of free will to be of significance. In discussing what people are and why free will matters to them, Dennett makes use of an evolutionary perspective. Dennett describes the mechanical behavior of the digger wasp Sphex . This insect follows a series of genetically programmed steps in preparing for egg laying. If an experimenter interrupts one of these steps the wasp will repeat that step again. For an animal like a wasp, this process of repeating the same behavior can go on indefinitely, the wasp never seeming to notice what is going on. This is the type of mindless, pre-determined behavior that humans can avoid. Given the chance to repeat some futile behavior endlessly, people can notice the futility of it, and by an act of free will do something else. We can take this as an operational definition of what people mean by free will. Dennett points out the fact that as long as people see themselves as able to avoid futility, most people have seen enough of the free will issue. Dennett then invites all who are satisfied with this level of analysis to get on with living while he proceeds into the deeper hair-splitting aspects of the free will issue.

From a biological perspective, what is the difference between the wasp and a person? The person can, through interaction with his or her environment, construct an internal mental model of the situation and figure out a successful behavioral strategy. The wasp, with a much smaller brain and different genetic program, does not learn from its environment and instead is trapped in an endless and futile behavioral loop that is strictly determined by its genetic program. It is in this sense of people as animals with complex brains that can model reality and appear to choose among several possible behaviors that Dennett says we have free will.

Both determinism and indeterminism seem to rule out free will

The deeper philosophical issue of free will can be framed as a paradox. On one hand, we all feel like we have free will, a multitude of behavioral choices to select among. On the other hand, modern biology generally investigates humans as though the processes at work in them follow the same biological principles as those in wasps. How do we reconcile our feeling of free will with the idea that we might be mechanical components of a mechanical universe?

What about determinism? When we say that a person chooses among several possible behaviors is there really a choice or does it just seem like there is a choice? Do people just (through the action of their more complex brains) simply have better behaviors than wasps, while still being totally mechanical in executing those behaviors? Dennett gives his definition of determinism on page one: All physical events are caused or determined by the sum total of all previous events. This definition dodges a question that many people feel should not be dodged: if we repeatedly replayed the universe from the same point in time would it always reach the same future? Since we have no way of performing this experiment, this question is a long-term classic in philosophy and physicists have tried to interpret the results of other experiments in various ways in order to figure out the answer to this question. Modern day physics-oriented philosophers have sometimes tried to answer the question of free will using the many-worlds interpretation, according to which every time there is quantum indeterminacy each possibility occurs and new universes branch off. Since the 1920s, physicists have been trying to convince themselves that quantum indeterminacy can in some way explain free will. Dennett suggests that this idea is silly. How, he asks, can random resolutions of quantum-level events provide people with any control over their behavior?

Indeterminism is not a solution to the free will problem

Since Dennett wrote Elbow Room (1984) there has been an ongoing attempt by some scientists to answer this question by suggesting that the brain is a device for controlling quantum indeterminacy so as to construct behavioral choice. Dennett argues that such efforts to salvage free will by finding a way out of the prison of determinism are wasted.[ citation needed ]

Control is the kind of freedom "worth wanting"

Dennett discusses many types of free will (1984). Many philosophers have claimed that determinism and free will are incompatible. What the physicists seem to be trying to construct is a type of free will that involves a way for brains to make use of quantum indeterminacy so as to make choices that alter the universe in our favor, or if there are multiple universes, to choose among the possible universes. Dennett suggests that we can have another kind of free will, a type of free will which we can be perfectly happy with even if it does not give us the power to act in more than one way at any given time. Dennett is able to accept determinism and free will at the same time. How so?

We have free will

The type of free will that Dennett thinks we have is finally stated clearly in the last chapter of the book: the power to be active agents, biological devices that respond to our environment with rational, desirable courses of action. Dennett has slowly, through the course of the book, stripped the idea of behavioral choice from his idea of free will. How can we have free will if we do not have indeterministic choice? Dennett emphasizes control over libertarian choice. If our hypothetically mechanical brains are in control of our behavior and our brains produce good behaviors for us, then do we really need such choice? Is an illusion of behavioral choices just as good as actual choices? Is our sensation of having the freedom to execute more than one behavior at a given time really just an illusion? Dennett argues that choice exists in a general sense: that because we base our decisions on context, we limit our options as the situation becomes more specific. In the most specific circumstance (actual events), he suggests there is only one option left to us.[ citation needed ]

"It is this contrast between the stable and the chaotic that grounds our division of the world into the enduring and salient features of the world, and those features that we must treat statistically or probabilistically. And this division of the world is not just our division; it is, for instance, mother nature's division as well. Since for all mother nature knows (or could know) it is possible that these insects will cross paths (sometime, somewhere) with insectivorous birds, they had better be designed with some avoidance machinery. This endows them with a certain power that will serve well (in general)." [1]

Determinism does not rule out moral responsibility

If people are determined to act as they do, then what about personal responsibility? How can we hold people responsible and punish them for their behaviors if they have no choice in how they behave? Dennett gives a two-part answer to this question:

First, we hold people responsible for their actions because we know from historical experience that this is an effective means to make people behave in a socially acceptable way. Second, holding people responsible only works when combined with the fact that people can be informed of the fact that they are being held responsible and respond to this state of affairs by controlling their behavior so as to avoid punishment. People who break the rules set by society and get punished may be behaving in the only way they can, but if we did not hold them accountable for their actions, people would behave even worse than they do with the threat of punishment. This is a totally utilitarian approach to the issue of responsibility. Expressing moral indignation when people break the rules of proper behaviour is only useful to the extent that it contributes to dissuading such behaviour. Again, an argument from utility. Is it, then, moral to punish people who are unable to do other than break a rule? Yes, people have the right to come together and improve their condition by creating rules and enforcing them. We would be worse off if we did not do so. Again, an argument from utility.

Fatalism is destructive

One final issue: if people do not have real behavioral choices, why not collapse into fatalism? Again, Dennett's argument is that we may not have behavioral choice, but we do have control of our behavior. Dennett asks us to look around at the universe and ask, can I even conceive of beings whose will is freer than our own? For Dennett, the answer to this question is, no, not really. In Elbow Room, he tries to explain why all the attempts that people have made to prove that people have libertarian choice have failed and are, in the final analysis, not really important anyhow. As humans, we are as much in control of our behavior as anything in the universe. As humans, we have the best chance to produce good behavior. We should be satisfied with what we have and not fret over our lack of libertarian free will.

Some complaints about Elbow Room relate to our intuitions about free will. Some say[ who? ] that Dennett's theory does not satisfactorily deal with the issue of why we feel so strongly that we do have behavioral choice. One answer to this question is the result of selection on individuals to live harmoniously in society. But one does not have to be free to achieve that goal. Another answer is that it tells us (our brains) whether we are doing something or someone else is doing something to us (e.g. shaking arm). But, again one does not have to be free to make such a distinction. A final answer to this question is that our sensation of having behavioral choice has been carefully selected by evolution. The well-developed human sensation of having free will and being able to select among possible behaviors has strong survival value. People who lose the feeling that they can plan alternative behaviors and execute their choice of possible behaviors tend to become fatalistic and stop struggling for survival. According to Dennett, belief in free will is a necessary condition for having free will. When we are planning for the future and thinking about possible actions to take in the future, we are utilizing considerable amounts of biologically expensive resources (brain power). Evolution has designed us to feel strongly that all of our effort of planning pays off, that we control what we do. If this connection between our brains' efforts to model reality and predict the future and so make possible good outcomes is disconnected from our sense of self and our will, then fatalism and self-destructive behaviors are close at hand. However, the same effect is attainted if, despite not believing in the control free will gives, we believe that does not prevent us to live as fully as our bodies allow us to and to try harder to achieve things if we think we have agency. In other words, we do not need to have the feeling of free will to accomplish our full selves. Nor does it explain the reason we experience we are not acting freely in survival-related actions but we experience free will in other sets of non-survival situations.

The Chinese room argument holds that a digital computer executing a computer program cannot have a "mind", "understanding", or "consciousness", regardless of how intelligently or human-like the program may make the computer behave. Philosopher John Searle presented the argument in his paper "Minds, Brains, and Programs", published in Behavioral and Brain Sciences in 1980. Gottfried Leibniz (1714), Anatoly Dneprov (1961), Lawrence Davis (1974) and Ned Block (1978) presented similar arguments. Searle's version has been widely discussed in the years since. The centerpiece of Searle's argument is a thought experiment known as the Chinese room.

<span class="mw-page-title-main">Determinism</span> Philosophical view that events are determined by prior events

Determinism is the philosophical view that all events in the universe, including human decisions and actions, are causally inevitable. Deterministic theories throughout the history of philosophy have developed from diverse and sometimes overlapping motives and considerations. Like eternalism, determinism focuses on particular events rather than the future as a concept. The opposite of determinism is indeterminism, or the view that events are not deterministically caused but rather occur due to chance. Determinism is often contrasted with free will, although some philosophers claim that the two are compatible.

Quantum indeterminacy is the apparent necessary incompleteness in the description of a physical system, that has become one of the characteristics of the standard description of quantum physics. Prior to quantum physics, it was thought that

In physics, a hidden-variable theory is a deterministic physical model which seeks to explain the probabilistic nature of quantum mechanics by introducing additional variables.

A deterministic system is a conceptual model of the philosophical doctrine of determinism applied to a system for understanding everything that has and will occur in the system, based on the physical outcomes of causality. In a deterministic system, every action, or cause, produces a reaction, or effect, and every reaction, in turn, becomes the cause of subsequent reactions. The totality of these cascading events can theoretically show exactly how the system will exist at any moment in time.

<span class="mw-page-title-main">Incompatibilism</span> Contradiction of free will and determinism

Incompatibilism is the view that the thesis of determinism is logically incompatible with the classical thesis of free will. The term was coined in the 1960s, most likely by philosopher Keith Lehrer. The term compatibilism was coined to name the view that the classical free will thesis is logically compatible with determinism, i.e. it is possible for an ordinary human to exercise free will, even in a universe where determinism is true. These terms were originally coined for use within a research paradigm that was dominant among academics during the so-called "classical period" from the 1960s to 1980s, or what has been called the "classical analytic paradigm". Within the classical analytic paradigm, the problem of free will and determinism was understood as a compatibility question: "Is it possible for an ordinary human to exercise free will when determinism is true?" Those working in the classical analytic paradigm who answered "no" were incompatibilists in the original, classical-analytic sense of the term, now commonly called classical incompatibilists; they proposed that determinism precludes free will because it precludes the ability to do otherwise. Those who answered "yes" were compatibilists in the original sense of the term, now commonly called classical compatibilists. Given that classical free will theorists agreed that it is at least metaphysically possible for an ordinary human to exercise free will, all classical compatibilists accepted a compossibilist account of free will and all classical incompatibilists accepted a libertarian account of free will.

Compatibilism is the belief that free will and determinism are mutually compatible and that it is possible to believe in both without being logically inconsistent. As Steven Weinberg puts it: "I would say that free will is nothing but our conscious experience of deciding what to do, which I know I am experiencing as I write this review, and this experience is not invalidated by the reflection that physical laws made it inevitable that I would want to make these decisions." The opposing belief, that the thesis of determinism is logically incompatible with the classical thesis of free will, is known as "incompatibilism".

Indeterminism is the idea that events are not caused, or are not caused deterministically.

Libertarianism is one of the main philosophical positions related to the problems of free will and determinism which are part of the larger domain of metaphysics. In particular, libertarianism is an incompatibilist position which argues that free will is logically incompatible with a deterministic universe. Libertarianism states that since agents have free will, determinism must be false and vice versa.

<span class="mw-page-title-main">Hard determinism</span> View that free will does not exist

Hard determinism is a view on free will which holds that determinism is true, that it is incompatible with free will, and therefore that free will does not exist. Although hard determinism generally refers to nomological determinism, it can also be a position taken with respect to other forms of determinism that necessitate the future in its entirety.

A philosophical zombie is a being in a thought experiment in philosophy of mind that is physically identical to a normal human being but does not have conscious experience.

In the philosophy of mind, the user illusion is a metaphor for a proposed description of consciousness that argues that conscious experience does not directly expose objective reality, but instead provides a simplified version of reality that allows humans to make decisions and act in their environment, akin to a computer desktop. According to this picture, our experience of the world is not immediate, as all sensation requires processing time. It follows that our conscious experience is less a perfect reflection of what is occurring, and more a simulation produced subconsciously by the brain. Therefore, there may be phenomena that exist beyond our peripheries, beyond what consciousness could create to isolate or reduce them.

<span class="mw-page-title-main">Bohr–Einstein debates</span> Series of public disputes between physicists Niels Bohr and Albert Einstein

The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr. Their debates are remembered because of their importance to the philosophy of science, insofar as the disagreements—and the outcome of Bohr's version of quantum mechanics becoming the prevalent view—form the root of the modern understanding of physics. Most of Bohr's version of the events held in the Solvay Conference in 1927 and other places was first written by Bohr decades later in an article titled, "Discussions with Einstein on Epistemological Problems in Atomic Physics". Based on the article, the philosophical issue of the debate was whether Bohr's Copenhagen interpretation of quantum mechanics, which centered on his belief of complementarity, was valid in explaining nature. Despite their differences of opinion and the succeeding discoveries that helped solidify quantum mechanics, Bohr and Einstein maintained a mutual admiration that was to last the rest of their lives.

Predeterminism is the philosophy that all events of history, past, present and future, have been already decided or are already known, including human actions.

The philosophy of artificial intelligence is a branch of the philosophy of mind and the philosophy of computer science that explores artificial intelligence and its implications for knowledge and understanding of intelligence, ethics, consciousness, epistemology, and free will. Furthermore, the technology is concerned with the creation of artificial animals or artificial people so the discipline is of considerable interest to philosophers. These factors contributed to the emergence of the philosophy of artificial intelligence.

In philosophy, moral responsibility is the status of morally deserving praise, blame, reward, or punishment for an act or omission in accordance with one's moral obligations. Deciding what counts as "morally obligatory" is a principal concern of ethics.

In quantum mechanics, superdeterminism is a loophole in Bell's theorem. By postulating that all systems being measured are correlated with the choices of which measurements to make on them, the assumptions of the theorem are no longer fulfilled. A hidden variables theory which is superdeterministic can thus fulfill Bell's notion of local causality and still violate the inequalities derived from Bell's theorem. This makes it possible to construct a local hidden-variable theory that reproduces the predictions of quantum mechanics, for which a few toy models have been proposed. In addition to being deterministic, superdeterministic models also postulate correlations between the state that is measured and the measurement setting.

The von Neumann–Wigner interpretation, also described as "consciousness causes collapse", is an interpretation of quantum mechanics in which consciousness is postulated to be necessary for the completion of the process of quantum measurement.
