Abstract

The idea that consciousness and complexity are closely related has been a major driver of the popularity of integrated information theory (IIT) of consciousness, despite its major formal, phenomenological, and neuroscientific shortcomings. Here, I argue that we can recover this intuition by replacing its biologically neutral notion of complexity with an evolutionary one that I shall dub "pathological complexity."
