'What is the basic building block of the universe?' Thales of Miletus was the first to ask this fundamental, yet to be answered, question in the sixth century B.C. This book offers an in-depth account of the answers he gave and of his adventure into many areas of learning: philosophy, science, mathematics and astronomy. Thales proved that the events of nature were comprehensible to man and could be explained without the intervention of mythological beings. Henceforth they became subject to investigation, experiment, questioning and discussion. Presenting for the first time in the English language a comprehensive study of Thales of Miletus, Patricia O'Grady brings Thales out of pre-Socratic shadows into historical illumination and explores why this historical figure has proved to be of lasting significance.

There can be little doubt that the Greek tradition of philosophical criticism had its main source in Ionia. . . It thus leads the tradition which created the rational or scienti?c attitude, and with it our Western civilization, the only civilization, which is based upon science (though, of course, not upon science alone). Karl Popper, Back to the Presocratics Harvard University physicist and historian of Science, Gerald Holton, coined the term “Ionian Enchantment”, an expression that links the idea back in the 6th c- tury B. C. to the ancient Ionians along the eastern Aegean coast, while capturing its fascination. Approximately within a seventy- ve year period (600–525 B. C. ) -a split second in the history of humanity- the three Milesian thinkers, Thales, Anaximander and Anaximenes, without plain evidence, but with an unequalled power of critical abstraction and intuition, had achieved a true intellectual re- lution; they founded and bequeathed to future generations a new, unprecedented way of theorizing the world; it could be summarized in four statements: beneath the apparent disorder and multiplicity of the cosmos, there exists order, unity and stability; unity derives from the fundamental primary substratum from which the cosmos originated; this, and, consequently, the cosmic reality, is one, and is based not on supernatural, but on physical causes; they are such that man can - vestigate them rationally. These four statements are neither self-evident nor se- explanatory.

In this new series leading classical scholars interpret afresh the ancient world for the modern reader. They stress those questions and institutions that most concern us today: the interplay between economic factors and politics, the struggle to find a balance between the state and the individual, the role of the intellectual. Most of the books in this series centre on the great focal periods, those of great literature and art: the world of Herodotus and the tragedians, Plato and Aristotle, Cicero and Caesar, Virgil, Horace and Tacitus. This study traces Greek science through the work of the Pythagoreans, the Presocratic natural philosophers, the Hippocratic writers, Plato, the fourth-century B.C. astronomers and Aristotle. G. E. R. Lloyd also investigates the relationships between science and philosophy and science and medicine; he discusses the social and economic setting of Greek science; he analyses the motives and incentives of the different groups of writers.

Ancient Greece was the cradle of philosophy in the Western tradition. Meet the Philosophers of Ancient Greece brings the thoughts and lives of the pioneers of Western philosophy down from their sometimes remote heights and introduces them to a modern audience. Comprising seventy essays, written by internationally distinguished scholars in a lively and accessible style, this book presents the values, ideas, wisdom and arguments of the most significant thinkers from the world of ancient Greece. Commencing with Thales of Miletus and continuing to the end of the Ancient Period of philosophy by way of Heraclitus, Parmenides, Protagoras, Socrates, Plato, Aristotle, Archimedes, Epictetus this book explores the major contributions of each philosopher as well as looking at archaeological and historical sites where they lived, worked and thought. This book is an outstanding introduction to the world of the philosophers of Ancient Greece.

In Miletus, about 550 B.C., together with our world-picture cosmology was born. This book tells the story. In Part One the reader is introduced in the archaic world-picture of a flat earth with the cupola of the celestial vault onto which the celestial bodies are attached. One of the subjects treated in that context is the riddle of the tilted celestial axis. This part also contains an extensive chapter on archaic astronomical instruments. Part Two shows how Anaximander (610-547 B.C.) blew up this archaic world-picture and replaced it by a new one that is essentially still ours. He taught that the celestial bodies orbit at different distances and that the earth floats unsupported in space. This makes him the founding father of cosmology. Part Three discusses topics that completed the new picture described by Anaximander. Special attention is paid to the confrontation between Anaxagoras and Aristotle on the question whether the earth is flat or spherical, and on the battle between Aristotle and Heraclides Ponticus on the question whether the universe is finite or infinite.
