What is the principle of all things of the universe for Parmenides

Answer 1

Parmenides, an ancient Greek philosopher, believed in the principle of monism. According to Parmenides, all things of the universe are ultimately based on the principle of being or existence (being is). He argued that existence is eternal, unchanging, indivisible, and continuous. Parmenides denied the existence of non-being or nothingness and regarded it as a concept filled with contradictions and logical inconsistencies. For him, everything that exists is a manifestation of being and is therefore real and permanent.
