Spiritual and Demonic Magic


Book Description

First published by the Warburg Institute in 1958, this book is considered a landmark in Renaissance studies. Whereas most scholars had tended to view magic as a marginal subject, Walker showed that magic was one of the most typical creations of the late fifteenth and sixteenth centuries. Walker takes readers through the magical concerns of some of the greatest thinkers of the Renaissance, from Marsilio Ficino, Giovanni Pico della Mirandola, and Jacques Lefevre d&’Etaples to Jean Bodin, Francis Bacon, and Tommaso Campanella. Ultimately he demonstrates that magic was interconnected with religion, music, and medicine, all of which were central to the Renaissance notion of spiritus. Remarkable for its clarity of writing, this book is still considered essential reading for students seeking to understand the assumptions, beliefs, and convictions that informed the thinking of the Renaissance. This edition features a new introduction by Brian Copenhaver, one of our leading experts on the place of magic in intellectual history.

Book Description

The present work contains a critical edition, translation, and study of the Summa perfectionis of Pseudo-Geber, the most influential of the many texts of medieval alchemy.

Spirits of Life and Perception


Book Description

Does a plant shrink at night and swell in the day, like an animal breathing in and out? For a long time, the Galenic concept of spiritus provided a causal explanation for human and animal life and perception. Albert the Great (1200-1280), whose honorific acknowledges among other things his pioneering work on biology, extended the concept to plants. This is only one of the remarkable concepts studied in this book, the first comparative study of Albert's concept of spiritus. It unveils the Arabic roots of his early psychophysiology and the original developments found in his mature Aristotelian paraphrases.
