Here Is Irony – Arguing that We Have No Free Will


Alex McGilvery

Ethical Technology

Posted: May 29, 2012

Free will is becoming the subject of ever greater amounts of research. I want to look at the ethical questions that arise from the discussion.

Neuroscientists have found that they can produce urges to move limbs or other actions by stimulating parts of the brain. By extension some suggest that all actions are just a result of stimulation from our environment and there is no choice involved. This research has added weight to the idea that since we live in a material world governed by specific laws; all our actions are therefore determined, if not predictable. The debate continues while most of us live our lives convinced that we are making decisions.

Let’s assume for starters that we have no free will, but that our actions arise totally out of stimulation in our environment. Out of that assumption there are several issues of importance. As listed in Scanlon’s article on “Ethics and Free Will”  they are personal responsibility, moral responsibility, and substantive responsibility. 

The lack of free will means that personal responsibility is a mirage. Since we are governed by stimulus/ response, there is no need to consider decisions since they are made for us before we “decide”. This, for the sake of argument, includes the emotional and psychological response to what is happening in the world.  If we are freed from personal responsibility, we are also freed from moral responsibility.  Nothing is our fault since we are only reacting to external stimuli. It then becomes morally repugnant to punish people for their actions (except that we are programmed to do so). Since nothing is our fault and we have no control, then logically we cannot be held to any agreements or promises we might have made.

The ancients thought that a person’s life was determined by fate. The Norse sagas and Greek myths are all about people who fought against their fate and lost in the end to the inevitable. Oedipus kills his father and marries his mother because that was his destiny and no amount of struggle could change that. In fact the Greeks believed that the struggle, while heroic, only made things worse. Still, both the Greeks and the Norse had complex codes of behavior and ethics that assumed a person was responsible for their actions, regardless of their predetermined fate. In fact the working out of that fate was inextricably entwined with the breaking or following of those codes. The really interesting part of the mythologies is that the gods, who would presumably have immeasurable power, were themselves subject to fate.

The lack of free will and its effects on ethics was also a part of Calvin’s idea of the elect. Our status as righteous or damned was determined before we were born. Our only choice was to live our lives in harmony with what was already determined. Even God was considered to be bound by predetermination and prophecies. Because humans had no free will to choice salvation or damnation, God too lost the ability to choose.

The idea that we have no choice is more prevalent in our present day culture than we want to admit. Books, movies and music talk about falling in love, for example, as an irresistible force. This erotic attraction is so powerful that it can drive us mad, shatter present relationships, even cause us to commit murder, and it is all OK because we fell in love. There is also the flip side of the emotional spectrum where we talk about “losing control” because someone pushed our buttons. Road rage is not our fault because we were overwhelmed by the stupidity of the other drivers.

In spite of our sense that we aren’t calling the shots, or at least not all of them, we have created complex systems of laws and ethics that assume that we are in control and responsible for what we do. One possible reason for this is that we are pushed to assume responsibility as a reaction against the notion that we have none. It is a smoke screen that our brains create to keep us on track. Like a child’s toy steering wheel in a car, we think it controls the car when in fact we are controlled by the car’s movements. Ethics gives us the illusion of control. It also provides justification for our actions:  I deserve to enjoy this meal; it is not just a stimulus/response mechanism. We are right to punish or even kill people who act contrary to our laws because we are protecting our community. Having justification means that we needn’t concern ourselves with the corollaries of our actions.

Now let us assume that free will does in fact exist, as this study suggests. This is not to say that there is no stimulus response mechanism or that we are completely in control of our actions at all times. Think of free will to be like breathing. Most of the time we breathe without thinking about it; the frequency of our breaths varies according to our activity without us needing to manage it. This is a very good thing since it would be overwhelming to try to control our breathing constantly to maintain the optimal flow of air into our lungs. There are times though when we take control and consciously decide to breathe deeply, or hold our breath, or exhale sharply.

Much of our lives is spent unselfconsciously responding to stimuli, yet there are times when we stop and make a deliberate decision to react differently than what the stimuli would suggest. We don’t punch out someone because we decide that it is contrary to our higher interests. Ethics in this scenario is the defining of our higher interest and ultimately of our species’ higher interest.  They are the boundary between what is acceptable as unconscious action and when we must take conscious control and responsibility for our actions. Thus ethics assumes that we have personal responsibility; namely, we make choices for ourselves, and by moral responsibility we can be held responsible for those choices. We then are accountable for the contracts and agreements we make and we must honour our promises.

Ethics when we are responsible for our decisions must then measure our ability to make those decisions and the results of our actions. When our automatic reactions produce damage to others, we are still accountable for those actions and responsible to learn new ways of acting. The implication is that we must train our actions in such a way as our unconscious activity is as ethical as the reasoned and conscious decisions.

There is a third possibility when it comes to free will, which is that some have, or will have, free will while others do not.  This scenario comes into play as we work on creating artificial beings. Right now there is work on making robots more and more autonomous. We would like space probes or military drones to be able to make decisions within certain parameters. If autonomy becomes self awareness, do we have the right to deny these new beings full free will? Will the evolution of consciousness in software/hardware mean that we will need to allow for the possibility that full autonomy and free will will mean that not only robots/AI will be able to choose to do harm, but that they must have the freedom to do so?  Asimov’s Three Laws of Robotics in this sense removes that final possibility of choice from his self aware robots and makes then eternally slaves to their programming.

It isn’t just robotics and AI that gives rise to the question of the free will to do evil. Advances in neuroscience may result in a device that makes it impossible for a person to complete a particular action; say murder or rape. The use of such a device would require careful thought and ethical review. Do we have the right to remove the ability to make a choice, even a wrong choice from another person? It could be justified by the use of informed consent; namely wear this device or live your life excluded from the community. It might also be seen as a reasonable breach of the rights of the perpetrator in the protection of community.

The question of free will and ethics is not one that we can simply let slide, no matter on which side of the free will debate we sit on. It is important that think through our understanding of the implications of free will or the lack of it, but most particularly the ethics around the boundary between the two states of being.

My dad used to say that the only exercise a person needed was from pushing yourself away from the table. Now I am 100 pounds overweight. Thank goodness I have no free will or I might feel guilty for not following my father’s dictum.





‘Free will’ is simply a sloppy way of thinking about how the human decision process occurs.

Because it forces us to consider both what ‘free’ means, and also ‘will’, neither of which have clear, objective physical correlates.

From a psychological perspective, I believe that the decision process is a constant feedback loop between desire and identity. In this case, by “desire”, I mean the “desire to become”, or the impulse to grow (this could be described in many different ways - but I am broadly inclusive enough to consider the drive that causes a seed to grow, and the desire to go to school to be fundamentally the same).

Let me use a very simple example to explain:

A student (this is the person’s current identity - ‘student’) desires to become a doctor, and thus attends school.

This person’s current identity is a product of their desire - since this desire to become (a doctor in this case) led the person to what she is right now - a student.

In the feedback loop, the current identity also leads to future desires. For example, while this student attends college, she learns that she doesn’t really want to become a doctor - after 2 years of medical school - and instead changes her major to philosophy of mind, where she studies questions of free will.

In this example, her desire to become a doctor leads her to become a student which then leads her to alter her desire to become a doctor.

All human decision processes, while more complex than this simple example, can be broken down this way.

Choice is a feedback loop between identity and desire.

We still live in a causal universe, for if we didn’t, we’d be swimming in a sea of non-perceivable chaos.

However, we don’t tend to make the “choices” we think we do, when we do - that is, those choices are generally made long before we actually experience them.

As the Oracle in the second Matrix movie says:

“You’re not here to make a choice, you’re here to understand the choice you’ve already made.”

Which is to say, because decisions are a product of this feedback between desire to become, and identity, our immediate actions are a result of the choice (to become) we made prior to actually experiencing the results of that choice (I chose to become a student - so now I experience the consequences - the homework - of that choice).

Choice is always (100% of the time) about identity/desire.

Having cleared that up, we can move on to whether fault finding, or blame assignation, has any value.

I say that it does not.

Fault finding, and blame assignation, is itself a form of abdication of responsibility, and stems from primal fear.

Let those who would choose to take responsibility (for anything) do so, and let those who do not want it not take it.

But to attempt to coerce or force another to take responsibility - which is what fault finding and blame assignation do - is irrational in the end.

One could make a utilitarian argument for it I suppose - that blame assignation is necessary for civilization, or something along those lines.

But I don’t believe it. At best, its’ a short term strategy for primitive societies.





@ iPan..

“From a psychological perspective, I believe that the decision process is a constant feedback loop between desire and identity.”

By associating the above, are you not simply just linking Free will with Self-reflexivity? and thus the illusion of Free will is substantiated and realised as further expression of illusion of Self and personhood?

For example, an insect or a mouse may have no or little notion and sense of Self and therefore motivations, (will to action), is driven solely by instinct and circumstance?

This is not to say that you have not highlighted a key “existential” phenomenon - that Free will is only “realised” in higher biological intellect and complexity? And that this “existential need” to follow desire and with need to perpetually seek to “define” ourselves to ourselves through actions/choices as well as through the eyes of others is not key to the expression of Free will?





In any case, if we accept the “freedom of will to choose” is subject to the “ability to contemplate choices”, (despite subjugation by the subconscious), then this is still valid reason enough to associate personal responsibility and be held accountable within society, (although technically society is merely a “collective of individuals”)?

My memory regarding the Matrix is a little shaky, yet was not the Oracle introduced purposefully by the “Grand Architect” as random chaos and “fuzzy logic” to get humans to accept their enslavement through struggle, suffering, and I guess by extension, the need for humans to define themselves through such suffering and struggle?





Part of my point is that the framing of human decision processes using the terminology “free will” is itself suspect. When we want to understand why humans do what they do, or how they do it, “free will” is a term with very little information in it - that is, it doesn’t tell us much at all about the very thing it attempts to define. It is “information sparse”.

This is because we need to define both “free” and “will” separately first. Define those components.

If we don’t, then the term “free will” itself does not make any sense.

So, how are we to define “free”, and then after that “will”?

Asking myself these questions, led me down the path to realizing that the process we humans actually use in making any decision that leads to action, is driven by two factors: identity (I am) and desire (I become). I’m drawing a line here in the way I use the word “desire” to specifically mean the “desire to become something” - not “wants” or “needs” (although these things are certainly components and/or factors - I merely mean to distinguish between “I want a cheeseburger now” or “I want a joint” and “I wish to become a doctor”, or “I wish to become a NASCAR driver”).

You said something that caught my eye and reminded me of something else, you said:

“This is not to say that you have not highlighted a key “existential” phenomenon - that Free will is only “realised” in higher biological intellect and complexity?”

This is essentially correct, though I currently believe it is more like a gradient, and I still wouldn’t choose to use those two words “free will”.

However, due to their extensive training - and in particular the meditation - I believe that monks of all sorts, and especially the Taoists and Buddhists - achieve this even more so than the rest of humanity.

That is, your point about “higher biological intellect and complexity” also extends to the discipline of these monks.

They have more “free will” (there’s that damn phrase again!) than the rest of us.

As far as blame assignation, fault finding, and liability goes - my point is simply that the majority of society is using a primitive system.

One should not assign responsibility, blame, or liability to others - it is choice for the individual to accept or not. To infer these things to other people without their express consent and voluntary acceptance of it is to me a violation of ethics - no matter what the circumstances are.





This description as “Free” will is rather outmoded perhaps, and the phrase does add unnecessary and questionable baggage in legal and philosophical arguments, (and even in our own minds?)

Perhaps we can settle to replace the phrase with the term “autonomy”, which seems to be less dubious and may be more sound/concrete for usage in legal cases?

“Autonomy” expressed as the right and power of Self-governing, and by extension acceptance of personal responsibility?

we can readily apply the term to future robotics also and even to A.G.I?





What happens when we apply process philosophy to human agency?

http://plato.stanford.edu/entries/process-philosophy/

The philosophy of process is a venture in metaphysics, the general theory of reality. Its concern is with what exists in the world and with the terms of reference in which this reality is to be understood and explained. The task of metaphysics is, after all, to provide a cogent and plausible account of the nature of reality at the broadest, most synoptic and comprehensive level. And it is to this mission of enabling us to characterize, describe, clarify and explain the most general features of the real that process philosophy addresses itself in its own characteristic way. The guiding idea of its approach is that natural existence consists in and is best understood in terms of processes rather than things — of modes of change rather than fixed stabilities. For processists, change of every sort — physical, organic, psychological — is the pervasive and predominant feature of the real.

Process philosophy diametrically opposes the view — as old as Parmenides and Zeno and the Atomists of Pre-Socratic Greece — that denies processes or downgrades them in the order of being or of understanding by subordinating them to substantial things. By contrast, process philosophy pivots on the thesis that the processual nature of existence is a fundamental fact with which any adequate metaphysic must come to terms.





Luke 23:24

Jesus said, “Father, forgive them, for they know now what they do.” And the soldiers gambled for his clothes by throwing dice.





^typo

Should say, “Father, forgive them, for they know not what they do”





“One could make a utilitarian argument for [fault finding and blame assignation] I suppose - that blame assignation is necessary for civilization, or something along those lines.

But I don’t believe it. At best, its’ a short term strategy for primitive societies.”

I agree that arguing about free will is a bit pointless. It’s a matter of perspective, and obviously taking responsibility for what we want, and encouraging others to do so, is likely to lead to the best futures, the law of unintended consequences notwithstanding.

Does that mean that we should eschew any form of coercion or fault-finding? Not always. I think there IS a utilitarian argument for these things, and it is not necessarily because our society is “primitive”. One can imagine primitive societies where such fault finding is unnecessary, and much more complex and sophisticated societies (such as the one we currently inhabit) where it is. But they are necessary evils, at best, and the kind of societies we should be aiming to build are indeed ones where responsibility-taking is something that just happens, not something that needs coercion or shaming.





“Does that mean that we should eschew any form of coercion or fault-finding?”

Yes.

In your own words:

“It’s a matter of perspective, and obviously taking responsibility for what we want, and encouraging others to do so, is likely to lead to the best futures,”

You do want the best future, right? So do I.

“But they are necessary evils, at best,”

I’m the kind of person that tends to believe that “necessary evils” aren’t necessary at all. That they always lead to slippery slopes that slide into total ruin.

Never cave into the “necessary evil” mode of thinking - that’s what gets us into these problems in the first place.





The idea that the “necessary evil” mode of thinking is what gets us into problems and should therefore be rejected is a common one, and would be more convincing if there wasn’t just as much evidence that failure to take tough decisions, including decisions that cause others to suffer, hasn’t also led to problems.

So this isn’t about caving in. This is about trying to figure out what is mostly like to bring about the kind of futures we actual want, such as those currently being discussed in response to Dick Pelletier’s latest. And from this perspective, the idea that “necessary evils” ALWAYS lead to slippery slopes that slide into total ruin strikes me as rather unhelpful, not least (but also not only) because it is false.





@Peter

I’m a fairly adamant follower of Kant’s Categorical Imperative (perhaps with some minor divergences, or clarifications - we have come a long way since then - but for the most part anyway…..)

This would put our arguments at odds…....





iPan, you can be an adamant follower of Mickey Mouse if you want, but actions still have consequences, and failure to take hard decisions also has consequences - generally negative ones. This is why I prefer to discourage naïve, simplistic thinking about these issues, irrespective of who your favourite philosopher might be.





Kant is not a naive, simplistic thinker, and neither am I.

Consequences.

Soon, our ability to model (simulate) the consequences of any action will be incredible - computing will allow us to simulate everything we do and it’s causal chain in near real time, just before we do those things.

However, my point is that in my experience, the pragmatism of “necessary evil” inherently comes with diminishing returns when it’s effects are seen over a longer period of time.

In other words, it’s a short term strategy, for immediate gain. Over longer periods of time, the Categorical Imperative is better.

To me, this is clearly evidenced in Game Theory experiments, like the Prisoners Dilemma.

Short term payoffs, which is what all “necessary evil” type policies fall under - are less positive in the long run.

Therefore, sticking to our principles, and universal values, even when they appear to cost us in the short term - is always a better idea than selling out, even briefly.





@Peter

The important point is not whether moral relativism leads to corruption, which is fairly obvious to anyone who thinks about it for a second - the Golden Rule is still more or less (we can allow for some slight adaptation of it based on research) true, no matter how you slice it or dice it.

No, the interesting question is, “Which values?”

We need to identify Universal Values.

I have discovered one:

Autonomy.

http://en.wikipedia.org/wiki/Autonomy

Autonomy (Ancient Greek: αὐτονομία autonomia from αὐτόνομος autonomos from αὐτο- auto- “self” + νόμος nomos, “law”, hence when combined understood to mean “one who gives oneself their own law”) is a concept found in moral, political and bioethical philosophy. Within these contexts, it is the capacity of a rational individual to make an informed, un-coerced decision. In moral and political philosophy, autonomy is often used as the basis for determining moral responsibility for one’s actions. One of the best known philosophical theories of autonomy was developed by Kant. In medicine, respect for the autonomy of patients is an important goal of deontology, though it can conflict with a competing ethical principle, namely beneficence. Autonomy is also used to refer to the self-government of the people.





@iPan

This is an important issue and therefore worth exploring with curiosity and open-mindedness. My previous comment was not the most respectful one I’ve ever written, I’ll admit, but was in part motivated by my frustration at the implicit “you don’t know what you’re talking about” on the basis of a simple reference to Kant. I prefer discussing actual arguments (and I note that the categorical imperative appears nowhere, at least not explicitly, in the arguments you’ve come up with since).

So to the arguments then.

David Deutsch has come to exactly the opposite conclusion about the evolution of predictability, and I’m inclined to find his version more convincing. The same AIs that you claim will allow us to predict the consequences of our actions will also be able to intervene in ways that make them more unpredictable than ever. Popper (the poverty of historicism) and Soros (with his, much underrated in my view, theory of reflexivity) have explained this type of point well. Add chaos theory (sensitive dependence on initial conditions) and the MWI, and we seem to be pretty much stuck with unpredictability.

Thankfully, unpredictability is not total. Of course you are right about consequentialist laws of diminishing returns, and there is something to be said for sticking to your principles, for sure. But my experience tells me that the best way to achieve good outcomes is to define them in advance, try to build consensus runs them, and in the mean time take whatever actions seem most likely to achieve it.

By the way we’ve discussed autonomy before; the counterpart is connection. I don’t mind trying to identify “universal values”, just as long as we bear in mind that choosing them is a matter of preference and consensus-building, not an issue of right and wrong. Consequences, on the other hand, are a matter of fact, not of choice: once you have decided the action you will take, the universe then pretty much decides on the consequence. So if you want to achieve something specific (even of it is, for example, to propagate the idea of autonomy as a universal value), then you need to respect the universe’s laws of cause and effect.
