who established the natural laws of the universe
Natural law Greek philosophy emphasized the distinction between "nature" (physis, φúσις) on the one hand and "law", "custom", or "convention" (nomos, νóμος) on the other. What the law commanded would be expected to vary from place to place, but what was "by nature" should be the same everywhere. A "law of nature" would therefore have the flavor more of a paradox than something that obviously existed.[1] Against the conventionalism that the distinction between nature and custom could engender, Socrates and his philosophic heirs, Plato and Aristotle, posited the existence of natural justice or natural right (dikaion physikon, δικαιον φυσικον, Latin ius naturale). Of these, Aristotle is often said to be the father of natural law.[3]
