An information integration theory of consciousness
Giulio Tononi · 2004 · BMC Neuroscience, 5, 42
Summary
Original statement of Integrated Information Theory, proposing that consciousness corresponds to the amount and structure of integrated information generated by a system.
Why it matters here
A key bridge source: it is not proof of panpsychism, but it explains why some consciousness researchers treat mind-like properties as potentially graded and widespread.
Linked claims
The view that the universe as a whole is conscious — sometimes called cosmopsychism. Distinct from panpsychism (which puts mind in atomic matter) and from idealism (which says reality is mental).
If consciousness is basic, the 'hard problem' dissolves. The cost is a major break with the standard physicalist picture.
If basic matter has a hint of experience, complex brains can build complex minds. The 'combination problem' is the catch.
