Abstract:
This journal article surveys the major figures of pre-Socratic philosophy, tracing the development of early Greek thought from the Milesian school through the Eleatics, Atomists, and Sophists, and concludes with the transition into the classical period. Beginning with Thales of Miletus, the study outlines how early thinkers seek naturalistic explanations for cosmology, change, and the structure of reality, rejecting mythological accounts in favor of rational inquiry. It examines the fragmentary nature of pre-Socratic evidence and the reliance on later writers such as Aristotle and Theophrastus for reconstructing their ideas. The article then explores the diverse contributions of Xenophanes, Heraclitus, Pythagoras, Parmenides, Zeno, Melissus, Leucippus, Democritus, and key Sophists including Protagoras, Gorgias, Antiphon, Hippias, Prodicus, and Thrasymachus. Finally, it situates these thinkers within the broader intellectual shift toward classical philosophy, showing how their investigations lay essential foundations for the systematic ethical, political, and epistemological frameworks developed by Socrates, Plato, Xenophon, Isocrates, and Aristotle.
