René Descartes is remembered as the prototypical dualist, proposing two substances or domains of existence: res extensa (stuff in space), and res cogitans (the stuff of thought/imagination/experience): matter and mind. Despite rejecting dualism, our culture is deeply cartesian.
Descartes' universe seems to mirror the biblical separation of the domains of earth and heaven: a world of matter coexisting with a world of agentic ideas, while our scientific universe only admits the existence of matter and pattern. Yet we are closer to him than the Christians.
@Plinz this thread follows the idea I wrote of: strings and loops in QM represent that what we see and create with our minds. this is the reason for Heisenberg uncertainty - you cannot measure both values because it would mean we would freeze in time + imaginary massless particles
