The Stoics, Epicureans and Sceptics

"The Stoics, Epicureans and Sceptics" by Eduard Zeller is a historical study of ancient philosophy written in the late 19th century. It examines how the Hellenistic schools—especially Stoicism, Epicureanism, and Skepticism—arose after Aristotle, setting their doctrines in logical, physical, ethical, and religious context. The work also follows later Eclectic and Neoplatonic trends and shows how this intellectual climate helped form early Christian thought. The opening of the book frames the volume (in the translator’s preface) as an introduction to post-Aristotelian thought that molded early Christianity, then lays out an extensive contents map. It first assesses Greece at the close of the fourth century BCE, celebrating Plato and Aristotle yet stressing deep flaws—overreliance on dialectic, limited observation, and sharp mind–world dualisms—rooted in broader Greek habits of thought and in political decline after Chæronea. It then explains how turmoil, cosmopolitan mixing, and the failure of civic life pushed philosophy toward practice: inner calm, independence from externals, a separation of ethics from politics, and moral universalism; from this came Stoicism, Epicureanism, and Skepticism, and later Roman–Alexandrian Eclecticism and religion‑tinged Neoplatonism. The text next introduces the Stoics’ history and character—eastern origins, cosmopolitan outlook, Zeno’s founding, Cleanthes’s stewardship, and Chrysippus’s decisive systematizing—while noting the loss of early writings and the need to rely on later sources. It sets the Stoic problem and divisions: philosophy as an art of virtue that still requires knowledge; debates over logic and physics; and the standard tripartition into logic, physics, and ethics. Finally, in beginning the section on logic, it sketches a theory of knowledge that starts from sensory impressions, builds common notions from experience, and locates the criterion of truth in “graspable” impressions that compel assent.
