Mind before matter: reversing the arrow of fundamentality

Abstract

In this contribution to FQXi's essay contest 2018, I suggest that it is sometimes a step forward to reverse our intuition on "what is fundamental", a move that is somewhat reminiscent of the idea of noncommutative geometry. I argue that some foundational conceptual problems in physics and related fields motivate us to attempt such a reversal of perspective, and to take seriously the idea that an information-theoretic notion of observer ("mind") could in some sense be more fundamental than our intuitive idea of a physical world ("matter"). I sketch what such an approach could look like, and why it would complement but not contradict the view that the material world is the cause of our experience.
