In this article, I consider the significance of the discovery of spermatozoa for Leibniz's deeply held beliefs that (i) no true substance can ever be generated or destroyed, except miraculously; and (ii) that every substance must be perpetually organically embodied. I further consider the way these beliefs are transformed as Leibniz's basic middle-period commitment to corporeal substance gives way (though not entirely) to a metaphysics of monadological immaterialsm. What endures throughout, I show, is the conviction that whatever is real must be indestructible, whether this is conceived as a form-matter compound in which the two components can never be entirely sundered from one another, or as a node of perception “absolutely destitute of parts”. Whatever the deepest metaphysical account of corporeality, Leibniz never abandons his interest in spermatozoa as the corporeal hosts of preexisting animals.

From sex and music to religion and politics, a history of irrationality and the ways in which it has always been with us—and always will be In this sweeping account of irrationality from antiquity to the rise of Twitter mobs and the election of Donald Trump, Justin Smith argues that irrationality makes up the greater part of human life and history. Ranging across philosophy, politics, and current events, he shows that, throughout history, every triumph of reason has been temporary and reversible, and that rational schemes often result in their polar opposite. Illuminating unreason at a moment when the world appears to have gone mad again, Irrationality is timely, provocative, and fascinating.

Though it did not yet exist as a discrete field of scientific inquiry, biology was at the heart of many of the most important debates in seventeenth-century philosophy. Nowhere is this more apparent than in the work of G. W. Leibniz. In Divine Machines, Justin Smith offers the first in-depth examination of Leibniz's deep and complex engagement with the empirical life sciences of his day, in areas as diverse as medicine, physiology, taxonomy, generation theory, and paleontology. He shows how these wide-ranging pursuits were not only central to Leibniz's philosophical interests, but often provided the insights that led to some of his best-known philosophical doctrines.Presenting the clearest picture yet of the scope of Leibniz's theoretical interest in the life sciences, Divine Machines takes seriously the philosopher's own repeated claims that the world must be understood in fundamentally biological terms. Here Smith reveals a thinker who was immersed in the sciences of life, and looked to the living world for answers to vexing metaphysical problems. He casts Leibniz's philosophy in an entirely new light, demonstrating how it radically departed from the prevailing models of mechanical philosophy and had an enduring influence on the history and development of the life sciences. Along the way, Smith provides a fascinating glimpse into early modern debates about the nature and origins of organic life, and into how philosophers such as Leibniz engaged with the scientific dilemmas of their era

This volume collects contributions from leading scholars of early modern philosophy from a wide variety of philosophical and geographic backgrounds. The distinguished contributors offer very different, competing approaches to the history of philosophy.Many chapters articulate new, detailed methods of doing history of philosophy. These present conflicting visions of the history of philosophy as an autonomous sub-discipline of professional philosophy. Several other chapters offer new approaches to integrating history into one's philosophy by re-telling the history of recent philosophy. A number of chapters explore the relationship between history of philosophy and history of science.Among the topics discussed and debated in the volume are: the status of the principle of charity; the nature of reading texts; the role of historiography within the history of philosophy; the nature of establishing proper context.

"Anton Wilhelm Amo is the first modern African philosopher to study and teach in a European university and write in the European philosophical tradition. We give an extensive historical and philosophical introduction to Amo's life and work, and provide Latin texts, with facing translations and explanatory notes, of Amo's two philosophical dissertations, On the Impassivity of the Human Mind and the Philosophical Disputation containing a Distinct Idea of those Things that Pertain either to the Mind or to our Living and Organic Body, both published in 1734. The Impassivity is an extended argument that the mind cannot be acted on, that sensation is a being-acted-on by the sensed object, and therefore that sensation does not belong to the mind, and must belong instead to the body The Distinct Idea works out the implications for the mind's actions, and tries to show how the mind understands, wills, and effects things through the body by 'intentions' which direct motions in our body intentionally toward external things. Both dissertations try to show how far each type of human act belongs to the mind, how far to the body, and expose and resolve earlier philosophers' self-contradictions on these questions"--
