Leo Strauss famously asserted that the fundamental, defining debate within Western civilization is that between Jerusalem and Athens, piety and philosophy, the Bible and Plato. And yet, surprisingly, Strauss never published any of his thoughts on Plato’s dialogue on piety, the Euthyphro. This volume presents, for the first time, Strauss’s 1948 notebook on the dialogue, written in preparation for a class at the New School for Social Research. Featuring close analysis and line-by-line commentary, the notebook opens a window onto a philosophic mind in action, as Strauss asks questions of the classic text, jots down observations and formulations, and analyzes very specific terms and arguments but also steps back, reviews the overall movement of the dialogue, and reconsiders previous conclusions. Beyond the notebook, the volume also brings together all the known materials that lay out Strauss’s thoughts on the Euthyphro. This includes newly transcribed and edited public lectures, illuminating appendixes, critical essays by volume editors Hannes Kerber and Svetozar Y. Minkov and scholar Wayne Ambler, an account of Strauss’s public lecture, and a new English translation of Plato’s Euthyphro by Seth Benardete, a classicist and one of Strauss’s students. Engaging and inspiring, Leo Strauss on Plato’s “Euthyphro� is a vital resource for scholars and students of political theory, readers interested in the intersection of philosophy and religion, and a must-have for anyone who studies Strauss.

In the early modern period, thinkers began to suggest that philosophy abjure the ideal of dispassionate contemplation of the natural world in favor of a more practically minded project that aimed to make human beings masters and possessors of nature. Humanity would seize control of its own fate and overthrow the rule by hostile natural or imaginary forces. The gradual spread of liberal democratic government, the Enlightenment, and the rise of technological modernity are to a considerable extent the fruits of this early modern shift in intellectual concern and focus. But these long-term trends have also brought unintended consequences in their wake as the dynamic forces of social reason, historical progress, and the continued recalcitrance of the natural world have combined to disillusion humans of the possibility-even the desirability-of their mastery over nature. The essays in Mastery of Nature constitute an extensive analysis of the fundamental aspects of the human grasp of nature. What is the foundation and motive of the modern project in the first place? What kind of a world did its early advocates hope to bring about? Contributors not only examine the foundational theories espoused by early modern thinkers such as Machiavelli, Bacon, Descartes, and Hobbes but also explore the criticisms and corrections that appeared in the works of Rousseau, Kant, Nietzsche, and Heidegger. Ranging from ancient Greek thought to contemporary quantum mechanics, Mastery of Nature investigates to what extent nature can be conquered to further human ends and to what extent such mastery is compatible with human flourishing.
