The Heraclitean-Eleatic Clash

Abstract

The problem of being, throughout their history a problem of classical science and philosophy, and now a critical one in nonclassical science, consists in the transition from the concept ‘is’ as the copula between subject and predicate (‘Bucephalus is a horse’), to the concept of ‘is’ as an absolute concept (‘Bucephalus is!’), to a concept which is associated (we will see later to what extent) with the concepts of ‘exists,’ and ‘exists in reality,’ etc.
