13 December: Barry Loewer, “The Mentaculus Vision”

For our last meeting of 2019, FraMEPhys will be hosting a talk by Professor Barry Loewer (Rutgers University) on Friday 13 December, from 2-4PM in Arts Lecture Room 5 (room 219). 

The Mentaculus Vision

Building on Boltzmann’s approach to statistical mechanics David Albert proposed a framework for a complete physical theory that entails a probability distribution over all physical possible worlds. Albert and Loewer call this framework “the Mentaculus.” In this paper I provide reasons to think that the Mentaculus entails probabilistic versions of the laws of thermodynamics and other special science laws, In addition it is the basis for a scientific account of the arrows of time and an account of counterfactuals that express causal relations. I then argue that the best way to understand the laws and probabilities that occur in the Mentaculus are along the lines of David Lewis’ best system account.
