Eleaticism
School of pre-Socratic philosophy that flourished in the 5th century
BC. It took its name from the Greek colony of Elea (Velia) in southern Italy. It is distinguished by its radical
monism — i.e., its doctrine of the One, according to which all that exists is a static plenum of Being as such, and nothing exists that stands either in contrast or in contradiction to Being. Thus, all differentiation, motion, and change must be illusory. Its literary sources consist of fragments (most less than 10 lines long) preserved by later Classical authors: 19 from
Parmenides, 4 from his pupil
Zeno of Elea, and 10 from another pupil, Melissus (fl. 5th century
BC).
