Mechanical: the contact theory, that one thing can only affect another by being in contact with it e.g. the teeth of gears.
Unfortunately, gravity ("spooky action at a distance") does not require contact, so the mechanical theory fails. Which can be stated figuratively as "the world is not a machine".
