Quote by Parmenides: “For from what is not, you will never make it be.”

Parmenides asserts the impossibility of creating something from nothing, reinforcing his argument that non-being cannot truly exist or become existent. This fundamental principle implies that everything that is, always has been in some form, emphasizing the eternal nature of being itself and the illogicality of creation from void.

This statement is a cornerstone of Parmenidean metaphysics, where he uses logical deduction to argue against the existence of 'nothing.' This concept had profound implications for physics and cosmology, challenging earlier ideas of emergent phenomena.

Greek philosopher from Elea, active around 480 BCE, who argued that all change and plurality are illusions and that reality is a single, eternal, unchanging whole. His philosophical poem On Nature survives in fragments and directly influenced Plato and many later Western philosophers. He is considered the founder of ontology, the study of being itself.
