For Being is, and non-Being is not.
ἔστι γὰρ εἶναι, μηδὲν δ' οὐκ ἔστιν

Philosophers
Parmenides
A pre-Socratic philosopher born in the late 6th century BCE in the Greek colony of Elea in southern Italy. In his didactic poem On Nature, Parmenides declared 'what is, is; what is not, is not,' dismissing change and plurality as sensory illusion. His ontological monism became the foundation of the Eleatic school, and through Zeno's paradoxes and Plato's Theory of Forms, it established the starting point of Western metaphysics. He is often called the founder of ontology.
