Parmenides:传记、成就与不朽的遗产

The single known work by Parmenides is a philosophical poem in dactylic hexameter verse whose original title is unknown but which is often referred to as On Nature. Only fragments of it survive, but the integrity of the poem is remarkably higher than what has come down to us from the works of almost all other pre-Socratic philosophers, and therefore classicists can reconstruct the philosophical doctrines with greater precision. In his poem, Parmenides prescribes two views of reality. The first, the way of "Aletheia" or truth, describes how all reality is one, change is impossible, and existence is timeless and uniform. The second view, the way of "Doxa" or opinion, describes the world of appearances, in which one's sensory faculties lead to conceptions which are false and deceitful.

Parmenides has been considered the founder of ontology and has, through his influence on Plato, influenced the whole history of Western philosophy. He is also considered to be the founder of the Eleatic school of philosophy, which also included Zeno of Elea and Melissus of Samos. Zeno's paradoxes of motion were developed to defend Parmenides's views. In contemporary philosophy, Parmenides's work has remained relevant in debates about the philosophy of time.
