The Mind-Brain Entanglement
Apr 18, 2019
Roland Poellinger, a mathematical philosopher at MCMP/LMU, explores formal models of how mental and physical domains interact. He discusses everyday mental causation examples, Bayes net interventionism, the Cambridge-change puzzle, and proposes Causal Knowledge Patterns with informational links. The talk connects these ideas to realization, mental influence on physics, and even a parallel to quantum entanglement.

Episode notes
Socrates And Xantippe Illustrate Cambridge Change
- Poellinger recounts Peter Geach's 'Cambridge change' using Socrates and Xantippe to show conflicting causal intuitions.
- The story exposes how identity or definitional links can feel non-causal yet matter for counterfactual checks.
Interventions As Local Surgeries
- Interventionist causal models (Bayesian nets) treat causes as variables we can 'do' to and test by clipping incoming edges.
- Distinct events must be represented by non-overlapping variables, and interventions are local surgeries in the model.
Need For Informational Links In Models
- Standard causal models cannot separately modify inseparable variables like Socrates' death and Xantippe's widowhood.
- Poellinger argues we need a new non-directed informational edge to capture instantaneous definitional links.
