What's the biggest barrier to thriving? A philosopher and a space architect answer | Ariel Ekblaw and Meghan Sullivan

In short

The biggest barrier to human thriving is distraction/inattention, and thriving requires designing toward the common good—moving toward an aspirational goal rather than settling for the least common denominator. The episode connects space habitat design and moral philosophy, arguing that principles like the golden rule and “looking at people again” can improve life on Earth. It also suggests space spending should benefit Earth first (e.g., space-enabled biology research).

Guests

Ariel Ekblaw, a space architect building how humans will live in space; studies “space commons” and norms for an aspirational interplanetary humanity. Megan Sullivan, a moral philosopher studying Aristotle through modern thinkers.

Key claims/examples

Common good as a shared future goal (not “splitting the difference”); Iris Murdoch’s idea: we owe others the willingness to see them again beyond stereotypes; in cramped habitats, the golden rule matters quickly. Overview effect—astronauts cry seeing Earth—should be democratized. Space research could help cancer/Alzheimer’s via orbit-based biology/organisms testing.

0:03You're listening to TED Talks Daily, where we bring you new ideas to spark your curiosity every day. I'm your host, Elise Hu. Our original series, TED Intersections, is back for a fourth season. The show features unscripted conversations between experts navigating ideas shaping our world. In this first episode, a space architect and a philosopher sit down and discover they've been circling the same questions all along, just from very different places. Ariel Ekblah builds the architecture for how humans will one day live in space. Megan Sullivan studies moral philosophy from Aristotle to the present.

0:41Put them in a room, and what you get is a wide-ranging conversation about what we actually owe one another, and what astronauts floating in orbit might teach us about being better humans here on the ground.

0:53Ariel Ekblaw: What we owe another person is to be willing to look at them again. Oftentimes we meet people and we sort of form our assumptions and stereotypes about them. We put them in a little category in our brain and then we interact with them according to that category. In this conversation, Ariel and Megan trade ideas on the common good, on human thriving, and what it would take to design a better world from scratch. They keep landing in a surprising place. that some of the same principles guiding a crew in cramped space habitats might be exactly what the rest of us need down here. Before we go be a sci-fi spacefaring species, maybe we earn our right to go do that someday by showing that we can take really good care of our own planet first.

1:35That's coming up right after a short break.

2:07We'll see you next week.

3:21Ariel Ekblaw: And now, our TED conversation of the day. It strikes me as somebody who's a huge space fangirl is what I would say. is that having these really concrete and ambitious goals, like going to the moon or putting people on the space station, sometimes forces us to focus our attention on solving problems that then help us solve problems back here on Earth. This is exactly what we want to do in space.

4:06What does the common good actually mean and how do we build towards it?

4:11Ariel Ekblaw: I think a lot of people assume that the common good means finding the kind of least common denominator that we can agree in, like just splitting the difference or kind of finding like going down to the basics. I think that is a huge mistake. The philosophers that I study and love, the ancient Greeks like Aristotle, believe that the common good, the good itself is something that you're moving towards. It's a common goal and nobody is there yet. So when we talk about prioritizing the common good, I think we're not trying to figure out of all the things that we believe and care about now, how do we sort of settle?

4:49Ariel Ekblaw: And figure out what we already share. Exactly. Instead, we need to be having this conversation of where do we collectively want to move to, which presumably is very different from where we currently are, which is probably not that great. I think this is really compelling. In our field for space, we think about the space commons and try to define what is the public good in the context of a really broad geographical expanse, like the near-Earth cocoon of space. And we don't have a real space commons yet. It does exist as a space, but we haven't defined all the norms yet. And so I love this. This is a way that we can think about moving together towards the definition of maybe a future goal, an aspirational version of humanity's commons.

5:28Ariel Ekblaw: And maybe trying to figure out what it means to be an interplanetary species. We might kind of exercise our imagination about how to be a better planetary species in the process. Love that. What do we owe each other as humans? Hmm. I think we should owe each other the alternative to the Hobbesian view. The idea that human nature is fundamentally wrought at its base or somehow pegged to our lowest basis instinct, I think we should owe each other our highest version of ourselves or our more honorable version of ourselves. Oh, I like that. So you disagree with Hobbes that life should be nasty, brutish, and short.

6:13That's pretty depressing. Should be elevated, you know, delightful, and long.

6:17Ariel Ekblaw: One of my favorite 20th century philosophers is a philosopher named Iris Murdoch. And she has a good answer to this question. She says, what we owe another person is to be willing to look at them again. Which means, like, oftentimes we meet people and we sort of form our assumptions and stereotypes about them. We kind of put them in a little category in our brain and then we interact with them according to that category. We put them in a box too early. Oh, my gosh. And she's like, you know, 80 % of the time your first impression is pretty dumb. This is something I have learned in my life. I think for the last 10 years I thought I was great at first impressions and then judging people in a positive sense but quickly and decisively.

6:56And I think I have learned recently that I really do need to give people a second look. I love this comment.

7:00Ariel Ekblaw: And just being able to like say, all right, I've got a vibe on you. I'm going to just put this on the shelf and just take it. And she's like really look at the person. Just make yourself see like there's a person there. So I think if we did that, maybe things would start to go better. If you could design a better world for humans from scratch, what's the first rule? You know, I come at philosophy from a Catholic perspective. and in the Jewish tradition and the Christian tradition, there was a fundamental rule that was laid down in the beginning that then we just promptly disregarded, which is you will love your neighbor as another self, like as yourself.

7:41Ariel Ekblaw: Like you're going to put love at the basis of all the rest of your decision making. And pretty much as soon as that kind of fundamental operating principle was laid down, we all started ignoring it and like revising it. So I don't know if I would revise the original code, but I would maybe enforce it a little bit harder. I don't know if that's allowed as an answer. What would you do? I love this. I think in the context of space environments, we're often in isolated, confined environments, tiny, constrained little spaces. So if I was going to start with a new rule for humanity, I love the idea of an oldie but goodie, the golden rule, treat others how you would like to be treated.

8:19And I think that that actually would play out very well in a constrained space where the what goes around comes around rule happens very quickly with kind of a small, you know, proto group of humans in a space habitat. It's like almost a tiny little, you know, maybe not a civilization, but a tiny little society in its own right. So, yeah, something like recommitting to the golden rule and this sense of really treating other people in the way in which you would like to be received and seen and treated. I love it.

8:48Ariel Ekblaw: You're going to love this one. Oh, great. What is a hope you have for humans in the next 10 years? I have an aspiration for humans that more people get to experience the overview effect, which really means democratizing access to space so that more humans can fly up to low Earth orbit, look back down at the Earth and see the Earth from space. And even really serious military astronauts, very impeccably well-trained, brave people, they start to cry when they see the Earth from space. They lose control over their own emotions because it is so moving. And I would love to share that experience with more people.

9:27That's a hope I would have.

9:28Ariel Ekblaw: I think on my end, similar hope that, you know, we'd have a kind of realization. I'm very excited about the AI decade finally taking root. And I consider myself kind of pragmatic optimist about artificial intelligence. But my biggest hope is that we would use this powerful technology that we now have at our disposal to help a whole lot more folks realize what it means to be genuinely human, that kind of humans be the star. That it heightens the difference. Heightens the difference. And also, there's so much about our lives pre-AI that are dehumanizing. So many ways in which we learn, in which we work, that have never enabled us to really express what's special about being a human being.

10:11Ariel Ekblaw: And I'd love to think that now we have this technology, we would choose to develop it in a way that we're humans and our capabilities and virtues would be the star of the show. I don't know that that's going to happen. I'm kind of afraid it's not going to happen. But maybe if we had the chance to see where we stand in the perspective of the universe, it would go better. What is the biggest barrier to human thriving? The biggest barrier to human thriving, there are some really big barriers. But I think probably the biggest one is our inattention. We, you know, we're rational animals. We have extraordinarily great capabilities in us.

10:54Ariel Ekblaw: But the only way that we realize them, unlike most animals, which kind of mature and develop their powers no matter what, a squirrel becomes a good squirrel with that very little effort. Humans require a great deal of effort to become good versions of what we're supposed to be. And it requires a lot of attention, not just to ourselves, but attention on the part of our parents and teachers. And I think when we fail to flourish, it's not typically because we've had like some malicious plan that screwed up our lives. But really, we just never had the opportunity to focus on the good plans. So I would think distraction.

11:33Ariel Ekblaw: How about you? That's a great response. It's like we are really high-intensity creatures in the sense we need a lot of attention. We need a lot of explicit care and development to become maybe the best version of ourselves. For me, it's interesting. I think of this sometimes in the context of why do we spend so much money on space exploration? If some of the barriers to human thriving are things like poverty, war, climate change. There's a lot of things at a societal scale that might be keeping us from thriving in the way that we really could. And then it raises the question, why would we spend money on space at all in that context?

12:06And I think one of the things we could do to help human thriving is we can use space for the benefit of life on Earth. So before we go be a sci-fi space-faring species, maybe we earn our right to go do that someday by showing that we can take really good care of our own planet first. So try to do things in space that would help with human thriving. And my latest favorite one is biology. It turns out biology is really different when you're floating in orbit than when you're on the ground. And so we might be able to do things like cancer cures, Alzheimer's, organoids testing, all kinds of interesting things that would maybe help humans thrive in a more concrete, immediate way on Earth, but leveraging space technology.

12:47Ariel Ekblaw: It strikes me as somebody who's a huge space fangirl is what I would say, is that having these really concrete and ambitious goals like going to the moon or putting people on the space station sometimes forces us to focus our attention on solving problems that then help us solve problems back here on Earth. And having a big vision like that, sometimes exactly the kick in the pants you need to feel motivated to take on something that in your ordinary life might not feel like it deserves your attention. This is exactly what we want to do in space. How do we build systems that influence the good in each other?

13:22Systems that influence the good in each other also have to assume good intentions at the base. And so being able to think about what is the architecture of policy that comes out of the U.S. government or ways that we could unify people to get them there. And I've recently become really passionate about something completely outside of my domain, so maybe I'm a little over my skis, which is the idea of a national service. Not necessarily a military draft. My parents are both ex-military. I'm very supportive of the military. But something that would be like every young person does something for a year when they're 18.

13:54And it really unites red and blue state kids and urban and rural kids. And it could be Teach for America. It could be something that's service-oriented, also maybe military service-oriented. But something like that, I think, once you get to know the people of your community and your village and your society and your civilization a little bit better, I think you can do a better job of finding the good in them and then maybe building good systems around them. I love that.

14:19Ariel Ekblaw: I think on my end, there are a few institutions that really roll up their sleeves and do this work of forming people's characters. One is education. Another would be like church and religious organizations. And a third is the media. And everybody likes to talk about how awful, you know, whatever fill in the blank social media is. But, you know, genuinely print media, the news and various sources still very much forms people's outlook and what they hope for and what they view as their sort of purpose in life. And I think we have sorely neglected those institutions. And a lot of people are really on the brink of nihilism, I think, right now about whether we could still imagine amazing schools, whether we could still imagine on the weekends you going and being with other humans and doing some kind of collective activity and I think if we really want to design systems that will bring out the good in people we've got to recognize that we are social animals and that these human level institutions need to remain strong and need our investment and our attending so I would love to see just you know a renaissance of hope in what we're able to build in those kinds of institutions.

15:32I love this and just reinvesting and bringing humans together through these different institutions and the ways that we used to come together and convene and gather more religious and non-religious. I would love to do that with you. Let's start it. Let's do it. Let's do it. Thank you so much. It was a delight talking to you and getting to learn more about your work. Thanks. I had so much fun.

16:53This episode is brought to you by Okta, helping you secure and govern AI identity by bringing agents out of the shadows. AI agents are changing the way we work, helping businesses move faster than ever. They're running operations, making real-time business moves, and working together behind the scenes, often completely on their own. But moving fast with AI shouldn't mean leaving security behind. When invisible agents operate in the dark, they create massive security blind spots that make it hard to keep track of them all. Okta helps your team grow while staying secure by answering four critical questions.

17:27Where are my agents? What can they do? What are they doing? And how do I respond if they go rogue? You get a clear view of your agents, govern their identity, trace their behavior, and pull the plug the moment something goes wrong. Bring AI agents out of the shadows. Okta secures AI.
