Episode notes
Mechanism Became The Core Enlightenment Metaphor
- Mechanism became the central Enlightenment image: the universe, humans, and society were understood as machines governed by laws.
- Zach Porkou cites David Hume and Thomas Hobbes describing the world as 'one great machine' and the heart as 'a spring'.
Laplace's Demon Frames Predictability As Possible
- Mechanism implies knowability and predictability exemplified by Laplace's Demon: perfect knowledge of positions and forces yields perfect prediction.
- Porkou links this to modern computational thinking and the belief that increased data and processing will render the past and future calculable.
Reductionism Drove Disciplines Toward Physics
- Enlightenment reductionism pushed each discipline toward physics/math, seeking elementary particles as the final explanation.
- Alan Wheelis' summary shows biology chasing chemistry and chemistry chasing mathematics as part of the mechanistic dream.
