    While thought experiments are as old as philosophy itself, the weight placed on them in recent philosophy is distinctive. Even when scenarios are highly unrealistic, judgments about them are thought to have wide-ranging implications for what should be done in the real world. The assumption is that, if you can show that a point of ethical principle holds in one artfully designed case, however bizarre, then this tells us something significant. Many non-philosophers baulk at this suggestion.

    So too, I think, should philosophers. It's hard to imagine more terrible ways of thinking about philosophical problems than via thought experiment. At best, they ought to be used as examples of how not to think; or how to think in circumstances that are extremely constrained and rare.

    A recent instance in which the 'trolly problem' become prominent in public discourse I think illustrates this well. In Italy, during the height of their COVID problems, it was said that doctors were being forced to choose between patients - who ought to get treatment, and who should die. Predictably, this had a few commentators likening the issue to the trolley problem. In some ways, the likening was exactly right. However, the situation in Italy shed as much light on the trolly problem as did the other way around: that trolly problems only become problems in instances of acute disaster, when the normal run of things go totally out of whack. To think, on the other hand, that answers to the trolly problem - or answers about who should die - are generalizable into broader ethical principles, is, I think absurd.

    That's just one example. The article linked gives some nice intrinsic reasons why thought expriements make for pretty terrible philosophy. Among them of course being that thought experiments are almost uniformly artificial and, again, totally ungeneralizable. The article itself focuses on what it calls ethical thought experiments, but I think the same is true for other well known ones too. The damage that 'brain in the vat' thought experiments have wrought on philosophy of mind, for instance, is I think incalculable. But that's another story.

    In any case, this is mostly an excuse to pimp out the article, and induce some discussion about the role of thought experiments in philosophy more generally.

    Here is the tram problem in its infancy: http://www2.econ.iastate.edu/classes/econ362/hallam/Readings/FootDoubleEffect.pdf

    Interesting that Foot is not so interested in the solution, as to the comparison with the judge and the rioters. It seems to me that the tram problem fuss is a perversion of the original use to which it was put.



    And it was a tram, not a trolley. The 'mercan hegemony, again.

    Well, I took utilitarianism for prelims at Oxford in 1979, which was way before the trolley problem, and the lecturer to the prelims class posed much the same question, instead of about whether we'd join a posse to shoot a criminal, as part of his debate on act versus rule utilitarianism. I dont know if the trolley problem really helps any better to understand the conflict, because it doesn't actually require understanding the difference between act and rule utilitarianism, and people are led to believe their intuition is more important than learning the far more extensive thinking in prior history than intuition could really achieve by itself for most people Ive met.

    I'm not terribly troubled by thought experiments. If one offers an opinion based upon a principle, it's appropriate to hypothesize the application of that principle in novel situations. If it's apparent that the principle fails to provide an adequate solution in those hypothesized situations, you're faced with the choice of reconsidering the principles upon which you rely or in accepting that the principle works only to a point and then delineating those limits.

    The observation that many thought experiments are invalid because of hidden distinctions contained within them is true, but that just means the proper way to combat argument by analogy is by pointing out the distinctions that make the analogy disanalagous. The debate will then center on whether those distinctions are relevant to the broader point.

    What we're discussing here has real world application and is not limited to the philosopher's armchair. Anglo oriented legal systems rely heavily upon analogy of precedent, deriving principles from prior judicial opinions and applying them to novel situations. In the legal context, the prior and the novel situations are all actual (as opposed to hypothetical), and it's also logically appropriate to ask how the principle enunciated might apply in hypothesized situations (reductio ad adsurdem considerations worked out as well).

    The clever lawyer does exactly as the author indicates the informed medical provider does in the article you cited: he explains why the analogy doesn't apply, he points out distinctions, and he explains why the deciphered principle has narrow implications to only very particular situations.

    The fact that argument from analogy results in eternal bickering over which facts matter and why yesterday's decision shouldn't apply to today's facts is the nature of the beast, but that doesn't make it useless, especially in the legal context, where we defer to the court as the arbiter of who has got the analogy correct and how it shall be applied. Of course, even then, we fully expect those rulings to be rethought and reconsidered by later courts. I see this way of reasoning productive though, taking full advantage of human's capacity to think deeply into issues and in giving deference to those opinions most well thought out, especially those that have satisfied the most pressing hypothetical thought experiments.

    I think your view of their purpose is absurd. The point of ethical thought experiments is not to debate and come to some consensus of right or wrong.

    I’ve been over this before quite thoroughly and it is surprising how many people just dig their heels in at any suggestion that the ‘purpose’ they see might just be completely wrong.

    Any public proclamation is always biased by the perceived biases in others the proclaimer bring into the public sphere. For me the point of such ethical dilemmas framed in thought experiments (hyperbolic or otherwise) is to first and foremost be honest with oneself rather than curb personal thoughts simply because they’re uncomfortable.

    People in the emergency services and the army train in this manner. The same comes into play for us as individuals. It takes work to fortify our ethical positions with actual actions and behaviors that adhere to them. Probably all of us say one thing and do another a lot of the time, but preparation of thought can have us acting more like we’d have wished to rather than simply ignoring the inconvenient truth of our susceptibility to failing to act as we, at our core, truly deem fit.

    So too, I think, should philosophers. It's hard to imagine more terrible ways of thinking about philosophical problems than via thought experiment. At best, they ought to be used as examples of how not to think; or how to think in circumstances that are extremely constrained and rare.StreetlightX

    This is missing the point. The more extreme the scenario is serves only to bring up your personal take on the matter. They are opportunities to see why you think what you think, what you’d prefer to think, what you’d say as opposed to what you really think, and what can be done to balance these things ... to name a few paths of enquiry.

    That's just one example. The article linked gives some nice intrinsic reasons why thought expriements make for pretty terrible philosophy. Among them of course being that thought experiments are almost uniformly artificial and, again, totally ungeneralizable. The article itself focuses on what it calls ethical thought experiments, but I think the same is true for other well known ones too.

    I’ll have to have a closer look at it. Clearly the use I find they don’t from what you’ve espoused.

    I completely understand that a reasonable number of people find them actively repulsive - I just think they’re looking at them in too rigid a fashion.

    Interesting! I'd never actually read the paper before, and appreciate you linking it. It's interesting what Foot does: she doesn't use the thought experiment to draw any particular ethical conclusion, but rather, to help bring out what might be called ethically salient distinctions. And moreover, the tram - fair call about the 'gemony - is one amongst a whole slew meant to bring it out. She doesn't, then, engage in what the article - and me - are railing against: using a thought-experiment as a kind of litmus test that ought to then be generalized in some manner.

    It's definitely an interesting use of a thought-experiment. I withdraw some of my animus towards the darn thing, but will still note how circumscribed it's use was in the paper - as part of an effort to draw a new distinction.

    A couple of thought experiments we like.

    What is it like to be a bat? Nagel.

    What is it like to be a a light ray? Einstein.

    Is it something about ethics that makes them objectionable?

    I would say that ethics suffers from the usual problem of social sciences, that the object of the experiment is altered, not only by the experiment but by the theory which is applied.

    For example, protecting one's family is usually considered a strong justification for almost any action. However, in a time of plague, there is a more over-riding priority to stop the spread of disease, even at the cost of one's own or one's family's life. Obligations change, societies change, people change, and the morality of this or that action changes. There is no stable condition equivalent to the speed of light, or the use of echo-location, that can transfer to and from the thought experiment, and allow for universalising.

    Also, the p-zombie thought experiment is good for pointing out the difficulty with incorporating consciousness into a material framework. But also the difficulty when you don't, since p-zombie Chalmers is making the exact same argument!

    For some reason or none, it never meant anything much to me. Kind of like the trolley, you can make it go which way you want.

    A trolley operated by a p zombie is like a self-driving car, passengers or pedestrians? But the zombie has no morality by definition, we have to program it with our morals.

    Ethical thought experiments show us what we think we ought to think when unencumbered by all the shed load of physiological inputs, prejudices, memories, adrenelin, politics and sociology accompanying an actual moral decision. Since these are the meat of most moral questions I'm not sure what value that could possibly have.

    Then there's the bizarre dissonance between on the one hand clearly investigating something we don't currently know whilst on the other presuming we have such flawless knowledge of all the other variables that we can perform this mental trick of holding them steady whilst we conduct our 'controlled trial'.

    The p-zombie argument has little to do with ethics, but one might argue that torturing a p-zombie wouldn't be wrong since it doesn't feel pain.

    However, what if it turns out we're all p-zombies? Does that mean we get to torture one another? Probably we would adjust our ethics instead. Although I don't know what exactly it would men to say that I don't really experience suffering.

    Thought experiments remind me of children's fantasies.

    Child: Mummy I had a dream where I was just a big ball of pink goo in a jar!
    Parent: That's ok dear, it wasn't real.
    Child: It was scary.
    Parent hugs child.

    Philosopher: I have a thought experiment where I'm just a brain in a jar.

    Zombie experiments are dumb and bat experiments are dumb. Faster we get over them the better.

    They don't even deserve the name of experiments. It's just certain philosophies attempt to buy into the prestige of scientific association. Thought fantasies is a more appropriate appellation.

    The way I see it, that kind of thought experiment is more a tool to check how the moving parts of a philosophy work in extremis. If the result is absurd, that's good cause to check where that absurdity comes from.
