This book considers the concepts that lay at the heart of natural philosophy and physics from the time of Aristotle until the fourteenth century. The first part presents Aristotelian ideas and the second part presents the interpretation of these ideas by Philoponus, Albertus Magnus, Thomas Aquinas, John Buridan, and Duns Scotus. Across the eight chapters, the problems and texts from Aristotle that set the stage for European natural philosophy as it was practiced from the thirteenth to the seventeenth centuries are considered first as they appear in Aristotle and then as they are reconsidered in the context of later interests. The study concludes with an anticipation of Newton and the sense in which Aristotle's physics had been transformed.

The political thought of Socrates, Plato and Aristotle defended and justified the values and way of life of the declining and decaying landed aristocracy in opposition to Athenian democracy and the craftsmen, traders and labourers upon which it increasingly rested. Although the Socratics recognized and condemned aristocratic regeneration, they hoped that the outlook and conduct of the nobility could be revitalized so as once more to become the foundation of civic life in order to stem the levelling tide of democracy, the tyranny of the mob, and the vulgarity that they felt were endangering Greece and especially Athens. To be understood and appreciated fully, the classics of political theory must be viewed as basically ideological and much more closely and rigorously related to their social contexts than has usually been the case. The point of departure for this critique of the Socratics is a particular conception of the Greek polis and its significance for Western social organization, an interpretation differing from most standard treatments. Besides casting new light upon the political thought of the Socratics, this study should help to illuminate the aristocratic myth about the character of the demos which, immortalized by the Socratics, has been a cornerstone of anti-democratic ideology and social theory in the West ever since the ancient philosophers first recorded their fears of the 'mob'.

A bold new interpretation of Aristotelian thought is central to Bernard Yack's provocative new book. He shows that for Aristotle, community is a conflict-ridden fact of everyday life, as well as an ideal of social harmony and integration. From political justice and the rule of law to class struggle and moral conflict, Yack maintains that Aristotle intended to explain the conditions of everyday political life, not just, as most commentators assume, to represent the hypothetical achievements of an idealistic "best regime." By showing how Aristotelian ideas can provide new insight into our own political life, Yack makes a valuable contribution to contemporary discourse and debate. His work will excite interest among a wide range of social, moral, and political theorists.
