Episode 125: James Koppel discusses counterfactual inference and automated explanation

Ep. 125
Episode link here.In this episode, James Koppel (MIT, James Koppel Coaching) joins me and Dominick Reo to talk about how we can write software to help identify the causes of disasters.These days, there's often a tendency to think of software primarily as a venue for frivolous pleasures. Maybe there's a new app that's really good at hooking me up with videos of alpacas on skateboards, or making my mom look like a hot dog when she's video chatting with me, or helping me decide what flavor of cupcake I want delivered to my home—because gosh, I just am just way too stressed right now to be able to figure that out. Have you seen how few Retweets I'm getting? If we followed the lead of a lot of the popular rhetoric about the software industry, we might very well come away with the impression that tech exists solely to facilitate precious, self-involved time wasting. And if that's right, then if it doesn't work from time to time, who really cares?But in fact, software correctness is frequently a life or death matter. Computer software controls our medical life support systems, it manages our health care records, it navigates our airplanes, and it keeps track of our bank account balances. If the author of the software used in any of those systems messed something up, it can and often will lead to planes crashing into mountains, or life support systems malfunctioning for no particular reason, or some other tragedy.James Koppel is here to tell us that software can do better. It can be designed ‘preventatively’ to avoid large classes of bugs in advance, and there are diagnostic techniques that can help pinpoint those bugs that cannot be ruled out in advance. In this episode, Koppel discusses some work he started in 2015 as a follow-up to Stanford's Cooperative Bug Isolation project, which provided a way to gather detailed diagnostics about the conditions under which programs fail or crash. But the problem he kept running into was that the diagnostic information was too much correlation and not enough causation. If the analysis you did tells you that your app crashes whenever it tries to load a large image, that's ok, but it doesn't tell you what about the large image causes the crash, or what other kinds of large images would also cause a crash, or whether the crash even is a result of largeness or something more specific. Correlation information is a great start, but ultimately, it's of limited use when it comes to directly fixing the problem.To deal with this, in his more recent work, Koppel and his colleagues have turned to the analysis of counterfactuals and causation, which is an interesting point of collaboration between philosophers and computer scientists. Using a recent paradigm called probabilistic programming, they have identified a way to have a computer program run the clock back and simulate what would have happened, had some condition been different, to determine whether that condition is the cause of a bug. The project is still in its initial stages, but if it works, it promises to deliver major dividends in making the technology we rely on more reliable.Tune in to hear more about this exciting new area of research!Matt Teichman

Elucidations Episode 124: Graham Priest discusses Buddhist political philosophy

Ep. 124
Episode link here:https://elucidations.now.sh/posts/episode-124/In this episode, Graham Priest returns to discuss Buddhist political philosophy with me and Henry Curtis.(Last month, we talked with him about Buddhist metaphysics.)Last month, we discussed the Four Noble Truths of Buddhism: that suffering happens, that this suffering is (partially) caused by emotional attachment, that you can deal with it by changing your headspace, and that you can change your headspace by understanding the world, understanding your mind and body, and treating other people well.In this episode, our guest adds something to that list, which he calls the '0-th noble truth'.This is the idea that suffering is bad.That idea appears as a foundational premise across many different Buddhist philosophical traditions, and he suspects that it can be used as the basis for political philosophy.You might remember last month's episode when we talked about 'anatman', which is the Sanskrit word for the Buddhist principle that there is no self.Priest makes the interesting proposal that the 0-th Noble Truth plus 'anatman' gives us the view that we should care about suffering equally no matter who is suffering.We should just try to reduce the global amount of suffering anywhere in the world.Graham Priest then argues that industrial capitalism is the cause of a lot of the suffering in today's world.Countless numbers of people are compelled by circumstance to work in exploitative jobs that overwork and underpay them, while others reap the profit from their work.If that further claim is correct, then it would seem to lead to the conclusion that a political philosophy based on Buddhist ethics would have to propose some alternative to industrial capitalism.Would a political system based Buddhist principles then have to look like socialism, or communism, or anarchism?Maybe, but the question turns out to be a bit complicated.Tune in to find out!Would a political system based Buddhist principles then have to look like socialism, or communism, or anarchism?Maybe, but it's a bit complicated.Tune in to find out!

Episode 123: Graham Priest discusses Buddhist metaphysics

Ep. 123
In this episode, Matt Teichman and Henry Curtis talk to Graham Priest (CUNY Graduate Center) about the philosophical foundations of Buddhism.Buddhism isn't just a religion--it's an entire family of philosophical traditions that took root all over the Asian continent for thousands of years. The historical Buddha articulated views in what we consider to be many different areas of philosophy, including metaphysics, ethics, and political philosophy. For this episode, we're focusing on the metaphysics.Metaphysics means different things to different people, but our guest thinks of it as a broad inquiry into the structure of reality at a fundamental level, space and time, what substance is, cause and effect, what makes any given thing the thing it is. And one of many things he finds interesting about Buddhism is that over the years, Buddhists have floated metaphysical views that don't arise in the Western traditions.One cool example he gives is a view associated with Madhyamaka Buddhism that nothing has a nature that makes it independent of its relation to anything else in the world. So take me, Matt. I am what I am not just because of properties that I have in and of myself, but because of the relation I stand in to certain other things. (Though not all other things, as he hastens to point out.) Like for example, I have a special relation to New Jersey: I was born and grew up there. So facts about what Matt is and what he's like is are tangled up with facts about what New Jersey is and what it's like.Graham Priest further observes that this general view leads to skepticism about whether anything is maximally explanatorily basic, which is a view that hasn't been explored by many contemporary philosophers. Like, most contemporary philosophers who work on metaphysics would say that a flagpole is more basic than the shadow it casts, because you could have the flagpole without the shadow, but not the other way around. There wouldn't be anything for the shadow to be a shadow of! Priest thinks that the Madhyamaka view that everything is dependent on something else leads to the further view that no one thing or set of things can be most basic.Join us as our guest walks us through the core metaphysical tenets of Buddhism!
