Next meeting: Thursday, September 17, 2026
7pm-8:30pm (MTN)
Registration is free and open to all.
You share an apartment with two roommates. You get along, you argue about the dishes, you figure you owe each other some basic decency. Then a genetic test reveals that one of them is a Neanderthal — and the other isn't organic at all.
Does that change what you owe them?
This month we take up philosopher Jeff Sebo's argument that the boundary of moral concern is drawn far too narrowly — and that insects, and possibly AI systems, may belong inside it. We'll also give the skeptics their due: one of the interviewers in our source material thinks the whole line of reasoning proves too much.

No reading this time--just a video to watch here.
Key concepts:
Moral standing (moral status, moral patienthood) — mattering for one's own sake, such that one is owed consideration directly rather than via someone else's interests.
Candidate bases of standing — sentience (felt pleasure and suffering), bare consciousness, agency (setting and pursuing one's own goals), or mere life. Sebo notes we disagree about which is necessary or sufficient.
Welfare subject — a being whose life can go better or worse for it. The video-game character isn't one; the roommate may be.
Speciesism and substratism — prejudice by species, and its projected successor: prejudice against beings made of the wrong material.
Precautionary principle — under doubt, treat the being as though it matters, on the grounds that mistaking a subject for an object is worse than the reverse.
Expected moral value — multiply the probability a being matters by how much it would matter if it did, and treat the product as its actual weight.
Anthropomorphism / anthropodenial — the paired errors of attributing human pleasures and pains where there are none, and denying them where there are.
Human exceptionalism — the assumption that humanity always takes priority, individually and collectively.
Rebugnant conclusion — The idea that enough small beings can outweigh the interests a few large ones.
These sessions are participant-driven discussions focused on philosophical essays, facilitated by a trained CU Boulder philosopher. Our goal at each discussion is to build a philosophical dialogue by investigating as a community of thinkers. Each session focuses on a philosophical text, but we do not regard the authors we read as unquestionable authorities. Rather, we consider each author to be another voice in our shared dialogue.
To prepare, please read the selected text to the best of your ability. Most months you'll find a reading guide linked above. If you are unable to read ahead, please come anyway. We recommend bring a copy of the reading with you - digital or printed out.
At the discussion, after brief introductions and a review of the discussion policies, the facilitator will ask participants to share questions and ideas for group discussion. The facilitator will then guide the group in working through as many of their questions as possible before recapping and wrapping up the discussion.
No background in philosophy is expected or required. We are excited to discuss the ideas raised by your interaction with the text!
