The philosophical system or doctrines of the Eleatic school, particularly the ideas that reality is unchanging and that sensory perception is unreliable.
From Eleatic (relating to Elea) with the suffix '-ism' (a system of beliefs). The term is used in philosophy and intellectual history to describe the school's metaphysical positions and their influence on Western thought.
Eleaticism basically said 'your eyes lie to you'—and it took 2,000 years of physics to prove they had a point: at the quantum level, time and change ARE stranger than perception suggests.
