O'Connor Says Triangle in Mind Cannot Be Identical to Neurons Due to Different Properties
"You can imagine a triangle in your head. I'm told that the triangle that I can literally see in my head right now is the same thing as some neurons firing. I don't think so, because they don't have the same properties. The triangle has 3 sides. The neurons firing that correlate with my experience of that triangle don't have 3 sides."
About this episode
On this episode of On Purpose, host Jay Shetty sits down with philosopher and YouTuber Alex O'Connor for a wide-ranging conversation exploring consciousness, science, death, and the nature of philosophical inquiry. O'Connor, known for his debates and interviews on religious and philosophical topics, reveals a rebellious youth that included failing his first A-level exams before eventually attending Oxford. The conversation's most striking moments center on O'Connor's critique of scientific explanation versus description, where he argues that science fundamentally describes phenomena mathematically rather than answering foundational why questions about existence and consciousness. Drawing on Newton's own admission that he didn't know what gravity actually is, O'Connor contends that physics presupposes the existence of matter and therefore cannot explain its origin. O'Connor presents compelling evidence from split-brain patient research showing the left hemisphere confabulates explanations for actions initiated by the right hemisphere, suggesting humans constantly rationalize decisions after the fact without realizing it. He integrates Western neuroscience with Advaita Vedanta philosophy, arguing consciousness cannot be reduced to neural activity because mental experiences and brain states possess fundamentally different properties. The discussion culminates in O'Connor revealing his views on death, where he finds consolation in the philosophical position that the unified self is an illusion that never truly existed. He acknowledges this uncertainty about fundamental values prevents him from having children, as he lacks sufficient conviction about what constitutes a good life to responsibly raise another person.
Key takeaways
- O'Connor argues science describes phenomena mathematically but cannot explain foundational questions like the origin of matter or consciousness.
- Split-brain patient experiments demonstrate the left hemisphere confabulates explanations for actions, suggesting humans constantly rationalize decisions after the fact.
- O'Connor contends consciousness cannot be identical to brain activity because they possess different properties under Leibniz's Law of identity.
- O'Connor reveals his internal uncertainty about fundamental values prevents him from having children, as he disagrees with himself too much.
- O'Connor finds consolation about death through the philosophical view that the unified self is an illusion that never truly began.
- O'Connor stopped doing as many debates because they're fundamentally about ego rather than truth-seeking, though he acknowledges they can be entertaining.
- O'Connor draws connections between ancient Advaita Vedanta philosophy, modern neuroscience, and psychedelic experiences regarding the illusory nature of self.
