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).
Hermippus of Smyrna Hermippus of Smyrna (Greek: Ἕρμιππος ὁ Σμυρναίος ), a Peripatetic philosopher, surnamed by the ancient writers the "Callimachian" (Greek: ό Καλλιμάχειος ), from which it may be inferred that he was a disciple of Callimachus about the middle of the 3rd century BC, while the fact of his having written the life of Chrysippus proves that he lived to about the end of the century. His writings seem to have been of very great importance and value. They are repeatedly referred to by the ancient writers, under many titles, of which, however, most, if not all, seem to have been chapters of his great biographical work, which is often quoted under the title of "Lives" ("Bioi"). The work contained the biographies of a great many ancient figures, including orators, poets, historians, and philosophers. It contained the earliest known biography of Aristotle, as well as philosophers such as Pythagoras, Empedocles, Heraclitus, Democritus, Zeno, Socrates, Plato, Antisthenes, Diogenes, Stilpo, Epicurus, Theophrastus, Heraclides, Demetrius Phalereus, and Chrysippus. The work has been lost, but many later "Lives" extensively quote it.
