What philosophical principle of Galileo’s did his torus model fundamentally contradict?

Answer

The idea that experiments in a uniformly moving system cannot reveal absolute motion.

Galileo’s model relied on the absolute inequality of speed stemming from the Earth’s orbit to generate tides, which was inconsistent with his principle that internal experiments within a uniformly moving system cannot reveal that system's absolute motion.
