Gregory Vlastos was one of the twentieth century's most influential scholars of ancient philosophy. Over a span of more than fifty years, he published essays and book reviews that established his place as a leading authority on early Greek philosophy. The two volumes that comprise Studies in Greek Philosophy include nearly forty contributions by this acknowledged master of the philosophical essay. Many of these pieces are now considered to be classics in the field. Perhaps more than any other modern scholar, (...) Gregory Vlastos was responsible for raising standards of research, analysis, and exposition in classical philosophy to new levels of excellence. His essays have served as paradigms of scholarship for several generations. Available for the first time in a comprehensive collection, these contributions reveal the author's ability to combine the skills of a philosopher, philologist, and historian of ideas in addressing some of the most difficult problems of ancient philosophy. Volume I collects Vlastos's essays on Presocratic philosophy. Wide-ranging concept studies link Greek science, religion, and politics with philosophy. Individual studies illuminate the thought of major philosophers such as Heraclitus, Parmenides, Anaxagoras, and Democritus. A magisterial series of studies on Zeno of Elea reveals the author's power in source criticism and logical analysis. Volume II contains essays on the thought of Socrates, Plato, and later thinkers and essays dealing with ethical, social, and political issues as well as metaphysics, science, and the foundations of mathematics.

It is known that Maxwell’s electrodynamics—as usually understood at the present time—when applied to moving bodies, leads to asymmetries which do not appear to be inherent in the phenomena. Take, for example, the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet, whereas the customary view draws a sharp distinction between the two cases in which either the one or the other of these bodies (...) is in motion. For if the magnet is in motion and the conductor at rest, there arises in the neighbourhood of the magnet an electric field with a certain definite energy, producing a current at the places where parts of the conductor are situated. But if the magnet is stationary and the conductor in motion, no electric field arises in the neighbourhood of the magnet. In the conductor, however, we find an electromotive force, to which in itself there is no corresponding energy, but which gives rise—assuming equality of relative motion in the two cases discussed—to electric currents of the same path and intensity as those produced by the electric forces in the former case. Examples of this sort, together with the unsuccessful attempts to discover any motion of the earth relatively to the “light medium,” suggest that the phenomena of electrodynamics as well as of mechanics possess no properties corresponding to the idea of absolute rest. They suggest rather that, as has already been shown to the first order of small quantities, the same laws of electrodynamics and optics will be valid for all frames of reference for which the equations of mechanics hold good.1 We will raise this conjecture (the purport of which will hereafter be called the “Principle of Relativity”) to the status of a postulate, and also introduce another postulate, which is only apparently irreconcilable with the former, namely, that light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body..

A lavishly decorated handbook of medicine was conceived for the lay public on topics such as human health, healing, medicine, and household management.

Newly updated study surveys concept of space from standpoint of historical development. Space in antiquity, Judeo-Christian ideas about space, Newton’s concept of absolute space, space from 18th century to present. Extensive new chapter (6) reviews changes in philosophy of space since publication of second edition (1969). Numerous original quotations and bibliographical references. "...admirably compact and swiftly paced style."—Philosophy of Science. Foreword by Albert Einstein. Bibliography.

This collection introduces readers to some of the most respected Pre-Socratic scholarship of the twentieth century. It includes translations of important works from European scholars that were previously unavailable in English and incorporates the major topics and approaches of contemporary scholarship. Here is an essential book for students and scholars alike. "Students of the Pre-Socratics must be grateful to Mourelatos and his publishers for making these essays available to a wider public."--T. H. Irwin, American Journal of Philology "Mourelatos is a (...) superb editor, and teaching Pre-Socratics in the future with this collection on the reading list will not only be easier but also better."--Jorgen Mejer, The Classical World "The editor has done his work judiciously. It would be difficult to devise a better balance between different parts of the subject."--Edward Hussey, Archives internationales d'histoire des sciences "[This book] will undoubtedly become an indispensable aid for beginning and advanced students of the Pre-Socratics."--David E. Hahm, Isis. (shrink)

An analysis of phaedo 96c-606c seeks to demonstrate that when forms are cited as either "safe" or "clever" aitiai they are not meant to function as either final or efficient causes, But as logico-Metaphysical essences which have no causal efficacy whatever, But which do have definite (and far-Reaching) implications for the causal order of the physical universe, For it is assumed that a causal statement, Such as "fire causes heat" will be true if, And only if, The asserted physical bond (...) between fire and heat instantiates the eternal and logically necessary relation of entailment between the instantiated forms, Fire, Heat.

I present an annotated development of the basic ideas of the Geneva School approach to the foundations of physics and the structures which emerge as mathematical representations of the physically dual notions of state and property.

Discusses the nature of thought and volition, examines past philosophical theories, and clarifies the relation between will and freedom.
