Philosophy Now

I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes: Imagine a thought experiment that merges two classic puzzles: > You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with? ### Questions to Wrestle With * If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt? * Could there be a "self" without continuity of experience — even moment to moment, while you sleep? On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement? I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!

Main Library, Meeting Room 2B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

By popular demand, the group wanted to read and discuss the semi-autobiographical novel by Henri-Pierre Roche, that inspired the Truffaut movie we watched last year. The book is available through the Columbus Library's interlibrary loan system. They reported there are twenty-eight copies available in the state of Ohio. If you have a library card, you can file an interlibrary loan request here: https://www.columbuslibrary.org/library-services/ . There are also used copies available on Amazon and eBay for under twenty dollars. You may want to rewatch the movie after reading the book, so we can compare and contrast in our discussion. The Columbus Library has four copies on DVD, and it's streaming on HBOMax.

Join the weight loss in Columbus group at the Scioto Audubon Park for an in person meeting. We'll meet to chat casually, talk about goals and enjoy one of Columbus's wonderful parks. We'll meet at one of the outdoor shelters, which is covered in case of rain, is close to some walking trails, and there's also a climbing gym that people can try out (my favorite past time) if people are interested. Let's meet and see where we can take things!

We may pick a specific topic and post in advance or may discuss current events and various ad hoc topics . We would love to spend time hanging out and getting to know one another. Atheist, agnostics, other non-theists, and atheist-friendly people are welcome to join us. Note: COUNT operates a Facebook page at www.facebook.com/groups/COUNT.discussions (http://www.facebook.com/groups/COUNT.discussions/) to promote discussions among members and visitors.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
