The volume analyzes the natural philosophical accounts and debates concerning the vegetative powers, namely nutrition, growth, and reproduction. While principally focusing on the early modern approaches to the lower functions of the soul, readers will discover the roots of these approaches back to the Ancient times, as the volume highlights the role of three strands that help shape the study of life in the Medieval and early modern natural philosophies. From late antiquity to the early modern period, the vegetative soul and its cognate concepts have played a substantial role in specifying life, living functions, and living bodies, sometimes blurring the line between living and non-living nature, and, at other moments, resulting in a strong restriction of life to a mechanical system of operations and powers. Unearthing the history of the vegetative soul as a shrub of interconnected concepts, the 24 contributions of the volume fill a crucial gap in scholarship, ultimately outlining the importance of vegetal processes of incessant proliferation, generation, and organic growth as the roots of life in natural philosophical interpretations.

Ibn Sina (980-1037), known as Avicenna in Latin, played a considerable role in the development of both Eastern and Western philosophy and science. His contributions to the fields of logic, natural science, psychology, metaphysics, theology, and even medicine were vast. His work was to have a significant impact on Thomas Aquinas, among others, who explicitly and frequently drew upon the ideas of his Muslim predecessor. Avicenna also affected the thinking of the great Islamic theologian al-Ghazali, who asserted that if one could show the incoherence of Avicenna's thought, then one would have demonstrated the incoherence of philosophy in general. But Avicenna's influence is not confined to the medieval period. His logic, natural philosophy, and metaphysics are still taught in the Islamic world as living philosophy, and many contemporary Catholic and evangelical Christian philosophers continue to encounter his ideas through Aquinas's work. Using a small handful of novel insights, Avicenna not only was able to address a host of issues that had troubled earlier philosophers in both the ancient Hellenistic and medieval Islamic worlds, but also fundamentally changed the direction of philosophy, in the Islamic East as well as in Jewish and Christian milieus. Despite Avicenna's important place in the history of ideas, there has been no single volume that both recognizes the complete range of his intellectual activity and provides a rigorous analysis of his philosophical thinking. This book fills that need. In Avicenna Jon McGinnis provides a general introduction to the thinker's intellectual system and offers a careful philosophical analysis of major aspects of his work in clear prose that will be accessible to students as well as to specialists in Islamic studies, philosophy, and the history of science.

If Saint Thomas Aquinas was a great theologian, it is in no small part because he was a great philosopher. And he was a great philosopher because he was a great metaphysician. In the twentieth century, metaphysics was not much in vogue, among either theologians or even philosophers; but now it is making a comeback, and once the contours of Thomas's metaphysical vision are glimpsed, it looks like anything but a museum piece. It only needs some dusting off. Many are studying Thomas now for the answers that he might be able to give to current questions, but he is perhaps even more interesting for the questions that he can raise regarding current answers: about the physical world, about human life and knowledge, and (needless to say) about God. This book is aimed at helping those who are not experts in medieval thought to begin to enter into Thomas's philosophical point of view. Along the way, it brings out some aspects of his thought that are not often emphasized in the current literature, and it offers a reading of his teaching on the divine nature that goes rather against the drift of some prominent recent interpretations.
