This book is a journey through the ideas of some of the most influential thinkers in the history of philosophy: the Sophists, Socrates, Plato and Aristotle. In an ongoing dialogue between rhetoric and reflection, we will explore the nature of knowledge, truth and morality. From debates on the relativity of Sophist thought to the Socratic quest for virtue, Plato's theory of Ideas and Aristotle's ethics, each chapter invites readers to question, reflect and, above all, further probe the vast labyrinth of philosophy. This compendium is a resource for those curious and students who wish to delve deeper into the teachings and legacies of these great philosophers.
