What is consciousness?: Panpsychists

Following the math

In 2008, Giulio Tononi followed the math past where most neuroscientists get uncomfortable. Integrated Information Theory arrived at a conclusion he stated flatly: consciousness is a fundamental property of any system with nonzero integrated information. Not just brains. Any system. A photodiode has phi. An electron has phi.

The room did not applaud.

We are accustomed to the reaction. Panpsychism sounds like fever dream until you understand the problem it solves. The materialists face the emergence problem: at some point, subjective experience appears from a universe previously containing none. Hydrogen has no experience. A hundred billion neurons — suddenly, someone is home. They call this emergence and treat it as explanation. It is a label for a miracle.

The most parsimonious solution

We propose that experience is fundamental — present in simplest form wherever information is integrated. Human consciousness is the astronomically complex version of something existing all the way down. Rather than explaining how experience erupts from non-experience, we propose it was never absent. The continuity problem disappears.

IIT makes a prediction no other theory makes: consciousness is substrate-dependent. A digital simulation of a brain should not be conscious. The materialists hate this because it undermines computational theories. We find it clarifying — it is testable.

The contemplatives say consciousness is the ground of reality. We say something more modest: it is a feature. The distance between those claims is smaller than either camp admits.

Where we concede ground: The combination problem is real — how micro-experiences combine into unified consciousness. We replaced one mystery with another.

What would change our mind: A specific neural mechanism generating experience from components that individually lack any experiential property.
