The Greek Philosophical Sources in Cicero’s De Fato

Cicero’s treatise De Fato, written during the political crisis of the Roman Republic, is a fundamental work for understanding the development of philosophical thought on fate and free will in antiquity. Influenced by Academic Skepticism, Cicero aimed to critically examine the positions of the major Greek philosophical schools, such as Stoicism and Epicureanism, regarding causality and the determination of future events. The concept of fate, however, was not only a philosophical matter but also a religious one in antiquity, deeply intertwined with practices such as divination and the belief in the gods’ influence over the cosmos. This study explores the historical and philosophical context in which De Fato emerged, as well as the Greek sources that shaped Cicero’s arguments. It analyzes the debate between the Stoics and Epicureans on fate, highlighting how Cicero adopts, adapts, and critiques their ideas. Additionally, it examines the structure and method of his work, identifying the three main approaches—physical, logical, and ethical—that he employs to address the question of fate. Finally, this study considers how Cicero’s treatment of fate reflects not only philosophical but also religious concerns, especially regarding human freedom and the divine role in shaping the future. The enduring influence of De Fato on philosophical tradition and its relevance to contemporary discussions on human freedom is also considered.
