Daniel Graham offers a clear, accurate new translation of the eighth book of Aristotle's Physics, accompanied by a careful philosophical commentary to guide the reader towards understanding of this key text in the history of Western thought. It is the culmination of Aristotle's theory of nature: he explains motion in the universe in terms of a single source and regulating principle, a first `unmoved mover'.

This book presents some of the most recent trends and developments in Presocratic scholarship. A wide range of topics are covered - from the metaphysical to the moral to the methodological - as well as a broad a range of authors: from recognized figures such as Heraclitus and Parmenides to Sophistic thinkers whose place has traditionally been marginalized, such as Gorgias and the author of the Dissoi Logoi. Several of the pieces are concerned with the later reception and influence of the Presocratics on ancient philosophy, an area of study important both for the light it sheds on our evidence for Presocratic thought and for understanding the philosophical power of their ideas. Drawing together contributions from distinguished authorities and internationally acclaimed scholars of ancient philosophy, this book offers new challenges to traditional interpretations in some areas of Presocratic philosophy and finds new support for traditional interpretations in other areas.

The eighth book of Aristotle's Physics is the culmination of his theory of nature. He discusses not just physics, but the origins of the universe and the metaphysical foundations of cosmology and physical science. He moves from the discussion of motion in the cosmos to the identification of a single source and regulating principle of all motion, and so argues for the existence of a first `unmoved mover'. Daniel Graham offers a clear, accurate new translation of this key text in the history of Western thought, and accompanies the translation with a careful philosophical commentary to guide the reader towards an understanding of the wealth of important and influential arguments and ideas that Aristotle puts forward.

In this study, Daniel W. Graham addresses two major problems in interpreting Aristotle. First, should we reconcile the apparent inconsistencies of the corpus by assuming an underlying unity of doctrine (unitarianism), or by positing a sequence of developing ideas (developmentalism)? Secondly, what is the relation between the so-called logical works on the one hand and the physical-metaphysical treatises on the other? Although the problems appear to be unrelated, Graham finds that the key to the first lies in the second, and in doing so provides the first major alternative to the unitarian approach since Jaeger's pioneering developmental study of 1923.

Gregory Vlastos (1907-1991) 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.

"Explaining the Cosmos" is a major reinterpretation of Greek scientific thought before Socrates. Focusing on the scientific tradition of philosophy, Daniel Graham argues that Presocratic philosophy is not a mere patchwork of different schools and styles of thought. Rather, there is a discernible and unified Ionian tradition that dominates Presocratic debates. Graham rejects the common interpretation of the early Ionians as "material monists" and also the view of the later Ionians as desperately trying to save scientific philosophy from Parmenides' criticisms.

In Graham's view, Parmenides plays a constructive role in shaping the scientific debates of the fifth century BC. Accordingly, the history of Presocratic philosophy can be seen not as a series of dialectical failures, but rather as a series of theoretical advances that led to empirical discoveries. Indeed, the Ionian tradition can be seen as the origin of the scientific conception of the world that we still hold today.
