This month, we'll be watching a video instead of doing a reading: Spencer Case arguing that morality is real, not just a human invention. We'll explore the debate between moral realists—who argue that statements like "murder is wrong" are objectively true regardless of what anyone believes—and their skeptical opponents, who contend that morality is merely convention, evolutionary byproduct, or disguised self-interest. Along the way, we'll explore questions like: Can we really separate moral reasons from other reasons we accept without question? If evolution shaped our moral intuitions, does that make them unreliable—or does that same argument undermine all our beliefs? And if philosophers still disagree about ethics after centuries of debate, what hope do the rest of us have?
NOTE: No registration needed; just show up by clicking this zoom link https://cuboulder.zoom.us/j/94330957128
The video can be found here.
Key Claims
• Moral realism: Moral statements can be true or false, some are true, and their truth is independent of social convention or human desire
• If we accept that we have reasons for belief and self-interest, we may already be committed to accepting moral reasons too
• Moral reasons may not be categorically different from other reasons we readily accept
Discussion Questions
• If evolution shaped our moral intuitions, should that make us skeptical of them? What about our beliefs about self-interest or logic?
• Can morality just be a useful social technology without being "real"? Would that matter?
• Is there really just one kind of "ought," or are moral oughts fundamentally different from prudential or epistemic oughts?
• Does widespread moral disagreement (across cultures or among philosophers) give us reason to doubt moral realism?
• If moral facts existed but were totally inaccessible to us, would they still matter?
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!
