Which one for the first thinkers to form Free will in antiquity was also well-known for formulation of an atomic theory of the universe?
Free will in antiquity Free will in antiquity was not discussed in the same terms as used in the modern free will debates, but historians of the problem have speculated who exactly was first to take positions as determinist, libertarian, and compatibilist in antiquity. There is wide agreement that these views were essentially fully formed over 2000 years ago. Candidates for the first thinkers to form these views, as well as the idea of a non-physical "agent-causal" libertarianism, include Democritus (460–370), Aristotle (384–322), Epicurus (341–270), Chrysippus (280–207), and Carneades (214–129).
Western philosophy Western philosophy is the philosophical thought and work of the Western world. Historically, the term refers to the philosophical thinking of Western culture, beginning with Hellenic (i.e. Greek) philosophy of the Pre-Socratics such as Thales (c. 624 – c. 546 BC) and Pythagoras (c. 570 – c. 495 BC), and eventually covering a large area of the globe. The word "philosophy" itself originated from the Hellenic: "philosophia" (φιλοσοφία), literally, "the love of wisdom" (φιλεῖν "philein", "to love" and σοφία "sophia", "wisdom").
