CONCEPT
The Origin of Life and the Origin of Mind
Dyson's dual-origin thesis — the argument that
life and
metabolism emerged separately before combining, with the corollary that
minds and
the capacity for minds may similarly have dual origins whose separation the AI era has made visible.
In
Origins of Life (1985, revised 1999), Dyson proposed that the conventional framework for understanding the origin of life — which treats replication and metabolism as simultaneous emergences — was inadequate to the evidence. His alternative was a
dual-origin model: metabolism emerged first as a statistical phenomenon in populations of small molecules, replication emerged later as a separate phenomenon in populations of nucleic acids, and life as we know it was the symbiotic combination of the two. The framework is a specific contribution to origins-of-life research, but it carries a broader implication that
the You On AI cycle develops:
minds, too, may have dual origins. The
capacity for symbolic processing — the ability to manipulate representations according to rules — may emerge in substrates that lack the
phenomenal character of conscious experience. AI makes this separation visible: systems that process symbols with high competence without, apparently, experiencing anything from the inside.
