Existentialists and Trolleys
How might an existentialist approach this notorious thought experiment of ethical philosophy?
“Not only do we assert that the existentialist doctrine permits the elaboration of an ethics, but it even appears to us as the only philosophy in which an ethics has its place.” ―Simone de Beauvoir, Ethics of Ambiguity
“I started to know how it feels when the universe reels.” ―The Trolley Song (Meet Me in St. Louis)
How ought we to live? Every decision we make implies that we have some idea of the answer to that question, but it’s very rare to find someone who can articulate their answer confidently.
Most of us are just winging it, maybe hoping that it will all make sense eventually. We often act as though we suspect the answer is out there somewhere, and we were just unlucky enough to be home sick on the day it was covered in class. We buy self-help books or listen to TED Talks or follow gurus who promise us that if we align ourselves with some lodestone or other—follow your dream, devote your life to others, discover your passion, surrender to God’s plan, go with the flow, practice the law of attraction, don’t take yourself so seriously, find your true life partner—we’ll finally get what it’s all about.
Some of us become fanatics of ideas like these, at least for a while. But most of us patch together a little of this and a little of that and try to muddle through with a philosophy that’s something of a crazy quilt.
Introducing the Trolley Problem
The “Trolley Problem” is a choose-your-own-adventure story in miniature. It stretches the seams of these make-do ethical philosophies we’ve stitched together over our lives, and it has a way of making people a little embarrassed at how threadbare their ethics seem to be.
In the story, a runaway trolley is about to run over and kill several people who are on the tracks in its path and unable to get out of the way. You have an opportunity to stop or divert the trolley, saving those lives, but only at the cost of killing some other innocent victim. What do you do?
In one version of the Trolley Problem, you can divert the trolley onto another track by pulling a switch, but there’s someone on the second track who will be killed if you do. In a second version, you and some unfortunate fellow are on a bridge overlooking the track, and the fellow is just fat enough that if you were to shove him off the bridge and onto the rails below, his body would stop the trolley before it hits the people further down the track… but at the cost of killing the chubby fellow.
In either case you are asked whether you will sacrifice one life to save many, and so from one perspective the two story variants seem to be essentially identical, only differing in inessential details. But most people who are presented with the Trolley Problem would pull the switch but wouldn’t push the man off the bridge. Why might this be? The Trolley Problem seems at first glance to expose an inconsistency, or at least an absence of simple systematization, in the way many of us make ethical judgments.
People often seem to hold an unstable emulsion of two ethical systems in particular: consequentialist (will my act make things better?) and deontological (is my act good in itself?). But it’s not always clear which of these approaches to use in which situation, or why. The Trolley Problem pulls us into a scenario in which these approaches conflict, and asks us to pick one and to consider how we’re doing the picking. It is better for one to die than for several to die (consequentialist), yet people die in accidents all the time but it is positively bad for me to shove someone off a bridge (deontological). Which will it be?
Which system is right? Shouldn’t we at least be consistent? Ought we to choose one or the other of these approaches and then stick to it even when we get squeamish?
Existentialism to the Rescue, Sort Of
The existentialists don’t often get consulted when Trolley Problems come up, but I think they should be. They won’t tell you what the right answer is, but they can at least tell you why the right answer seems so elusive, and why your search for The Right Answer might really be a disguised way of avoiding the question.
Existentialism hopes to keep you from going off the track—by helping you avoid the temptations to duck out on your responsibility for choosing your own decision.
From the existentialist point of view, the essence of a Trolley Problem is that it puts you in a situation that will inevitably result in a bad outcome. You have become entangled in this without your consent, but once you’re entangled there’s no getting out of it. You cannot decide not to be involved. The trolley will soon taste blood and you are going to be responsible for whose blood it is. You have to own up to this and make a decision and accept responsibility for how you will respond.
It’s not fair, but that’s life. You may always try to mind your own business, but you don’t always get to decide which business that is.
There are many ways to try to evade the responsibility for making a decision or for the consequences that follow, and the existentialist says they’re all bogus.
For example, you might draw a distinction between acting (pull the switch, push the man) and remaining passive (stand there and do nothing) and pretend that responsibility only attaches to the first sort of decisions and not to the second. How can I be responsible? I did nothing![1] The responsibility must lie with the trolley company or the Hand of Fate! The existentialist says that won’t fly.
Or you might fashion a rhetorical scalpel to separate your decision from its consequences. For example: when you pulled the switch, your “intent” was to divert the trolley from killing the people further down the track, and it was only an “unintended consequence” that the trolley went on to kill the person on the other track. (You’re fooling yourself again, says the voice under the beret.)
You can also try muddying the waters—coming up with so many “what if”s that you feel justified saying “well, there’s just no telling what the right decision is.” In real life, there’s plenty of uncertainty and “what if”s, and they legitimately make decision-making difficult and the consequences of our choices hard to predict. But we have to be on guard against hunting for uncertainty in order to evade responsibility.
The way this shows up in the Trolley Problem is the temptation to add complexity to a simple story—How do we really know the fat man is fat enough to stop the train? Are we sure we know how to correctly operate trainyard switches? What if the endangered people on the track ahead are a pack of scoundrels or a suicide cult, and the innocent person on the alternate track is a brilliant doctor about to find a cure for cancer?—We hope if we cover the problem with enough hypotheticals we will be too confused to decide in time, and then we can look at the consequences of our indecision and say, “but for all we know, the alternative might have been even worse, so what can you do?”
The Most Seductive Temptation
But perhaps the most seductive of all of the temptations is the search for a system that can make the decision for you. Whatever you choose, the trolley is going to kill somebody. And you desperately want to be able to tell the next-of-kin “It wasn’t me—I had no choice!” while you point at some Reason that compelled you to do whatever you did. “It was not me who decided to pull the switch, but The Greatest Good for the Greatest Number;” or: “it was not me who decided not to push the man off the bridge, but the Commandment ‘Thou Shalt Not Kill.’”
If you claim you found the correct answer inscribed on the fabric of the universe, so that all you had to do was to read it and obey its commands, you’re really making another attempt to avoid taking responsibility for making the decision yourself and owning the consequences. You will always be able to point to reasons that point to other reasons that point to still more, like a dog chasing its own tail, but you’re only playing hide-and-seek from the reality that the ultimate reason for your choice was “that’s what I chose.”
This is harsh medicine. When we go to a doctor, we don’t just want to be reminded that faith healing and crystals won’t cure our disease—we want to learn what will cure us. If existentialism neither relieves us of the burden of our responsibility nor guides us to the right answers—what good is it?
Existentialism may be more of a vaccination against bad answers than a source of good ones, but that may make it more valuable, especially when there’s so much snake oil out there, with such bad side effects. It’s a humble, human ethics that doesn’t promise more than it can deliver. The way Simone de Beauvoir put it: “Ethics does not furnish recipes any more than do science and art. One can merely propose methods.”
One problem with using the faulty ethical methodologies that existentialists criticize—“bad faith,” they call them—is that it’s being dishonest with yourself and not taking yourself seriously. It’s a way of disengaging from life and from reality: a sort of living suicide. But another problem is that it distorts your decision-making and encourages you to do things you wouldn’t do if you were thinking clearly. If you believe you can evade responsibility for your choices by making them conform to bad-faith excuses (for example: choosing inaction rather than action, choosing to obey the law because it is the law or to follow orders because they are orders, choosing whatever The Bible says or what was in your morning horoscope, conforming to the opinions of the majority), you will be biased toward decisions that come packaged with such excuses, rather than to good decisions. And you’ll be vulnerable to excuse-hawking scoundrels—gurus, demagogues, politicians, and the like—all eager to sell you the release from responsibility that you crave, for a price.
Existentialism protects you from the fatal costs of ethical disengagement, and, though it doesn’t always give you much help in finding the right answers, it doesn’t let the wrong answers get away with their seductive lies.
Clang, Clang, Clang… to the End of the Line.
A fanciful story like the Trolley Problem makes our conundrum easier to identify. Once we have been made aware of it, we may begin to hear the clang of the runaway trolley day in and day out. In most every waking moment we make decisions that affect the lives of others. How much have we been sleepwalking through these decisions or pretending that they were never ours to make? In Albert Camus’s The Plague, one of his characters describes the horrifying burden he felt when he realized how entangled he was in the lives around him:
We can’t stir a finger in this world without the risk of bringing death to somebody.… I have realized that we all have plague, and I have lost my peace.
It’s no wonder we are tempted to disengage, and to grasp at excuses to pretend this plague away. The Trolley Problem is more than just a thought experiment: it’s a metaphor for the entangled, uncertain, precarious lives we live. The trolley is screaming down the track towards its victims, and what happens next is up to you. You can no more rely on a philosophy than on a coin flip. How will you decide?
I tend to enjoy existential thoughts and ideas, and taking problems sincerely and staring at them head on. Adding in fluff to explain away realities, isn’t the preferred way I would want to find answers.
Though, even when I agree with the usefulness of being more clear-headed about situations we face in reality, the more I thought about this example you used, and how you dismissed the various ways to ‘explain away’ the situation, I got to thinking about why I also don’t find your comparison compelling.
Because, as you point out with regard to Camus, every action/inaction we make influences the world around us. Though in reality, the consequences are not clear to us. To apply a consistent value-system in a world that doesn’t ‘give’ results on moral actions the way it does physical ones, seems to be quite doomed to begin with.
Yes, it is highly improbable that you not pulling the switch would lead to the death of the five people, but it isn’t certain. Nothing Is certain in the way hypothetical scenarios present them. We can try to do our best, but that doesn’t mean it leads to the desired result, or to even a fixed result.
And so I guess I want to recognize that although it is a useful skill to be able to be more level-headed in the face of uncertainty, I don’t see your comparison as a good example of gaining moral consistency, as the Trolley Problem is a very clinical and ‘magical’ scenario.
In my view, existentialism is better applied as a mentality, a way to hold conflicts and difficult situations where we don’t see/feel that there are any good outcomes. Instead of being angry, getting reactive or making a choice that would make the situation worse, to try to bear the pain of there being no good options—whilst simultaneously not assigning any blame to each other on top of the felt ‘insert negative emotion’.
A decision, a mindset of intentions, of not adding that extra layer of ‘blame’ to any given situation that otherwise would just be.
I do agree with the temptation to shirk accountability, but there is also real and extreme terror in facing the reality of the world—and I’m pretty sure it is a reason many people go completely insane. It isn’t some easy fancy or useful tactic you can apply on a whim, or a nice skill to learn one summer. It is an extremely humbling paradigm shift, that changes one’s thoughts, feelings and perceptions of the world, and becoming both more accountable, and less reliant on ‘the gods’ or some external authority. A stance in the face of unavoidable hurt, pain and the continuous “infliction” of deprivation on oneself and others.
With the Trolley Problem we can have clear results, though that is not the case in life. There are too many uncertainties, and our viewpoints and axioms are scattered, lack enormous amounts of information, and are biased in ways that are in direct contradiction with our conscious intentions—and it is a lot of work to just make minor adjustments. This is also something to rest in, the paradox of being the master of ourselves, whilst also not really having control over anything at all.
And so I wonder if focusing on the Trolley Problem in a way is a subtle rejection of reality. The temptation to give in to a view of reality that is ‘simpler’ and makes more sense to our mind. Like a video game, where the actions are programmed, and the results consistent.
To sum up, I do agree with the use of existentialism in general, and some of its uses for sitting in difficult situations and not shirking our role in situations. Though, in general, do not agree with the link drawn to the Trolley Problem. The best uses of Camus and Absurdism has for me been to not assign ‘blame’ as an added layer to a reality in interpersonal relationships and also intrapersonally, by being more able to feel the feelings and thoughts underneath this deflective layer of blame.
I didn’t downvote this, because it seems good-faith and isn’t harmful. But I really dislike this “friendly” style of writing, and it doesn’t fit well on lesswrong. It’s very hard to find things that are concrete enough to understand whether I disagree or not. Rhetorical questions (especially that you don’t answer) really detract from understanding your POV. Some specifics:
Citation needed. In fact, purpose of statement needed—what does this actually assert, and how does it help in understanding … anything?
But only a TINY bit of reflection indicates that the differences are nowhere near inessential. Choosing between 5 people who’ve gotten themselves tied to the railroad tracks vs 1 person who has is simply a different situation than pushing an innocent bystander off a bridge. You don’t need to resort to a sledgehammer of different fundamental structures.
Not even close. It was me; I made the choice, and I understand that it sucks. For those who did not pull the lever/push the innocent, they ALSO made the choice, and it sucks.
I assume the audience here is a mix of sophisticated people who of course know all about the trolley problem, etc., and newbies who are attracted to rationalism or the LW ethos and are here to learn more about stuff. So I write in a mix of modes. I can’t say I’m confident about how I navigate this… it’s just kind of a gut feeling that there’s room for multiple styles.
As for your first point about ”...crazy quilt,” I expand on this later in the essay when I discuss how responses to the trolley problems show that commonly people sometimes lean on deontological reasoning, sometimes on consequentalist reasoning.
For the second point, I think my “so from one perspective” caveat anticipates your objection. If you are first confronted with the lever-pulling scenario and think “well, this is just a matter of simple mathematics,” the second scenario reminds you that there are other factors to consider.
For the third point, congratulations on having an existentialist perspective on this matter, but I’m confident that this is far from universal.
