Etienne Gilson's Gifford Lectures, given at the University of Aberdeen in 1931-1932. and published in French in 1932 under the title “The Spirit of Medieval Philosophy” (second edition 1969) is one of the most famous and fundamental books of the remarkable French philosopher and medievalist. According to Gilson, the defining feature of medieval philosophy was that it developed within the framework set by the Christian revelation, and this circumstance not only did not hinder the movement of philosophical thought, but also served as a powerful impetus for its expansion and deepening. Therefore, Gilson believes, we can talk about this philosophy as essentially Christian. The book has been translated into Russian for the first time. CONTENTS: Preface 5Chapter 1.
