"Oliver Smith’s Vladimir Soloviev and the Spiritualization of Matter is one of the best recent works in English about Soloviev, indeed about Russian philosophy in general. It tackles complex philosophical concepts with unusual clarity, lucidity and cohesion, exploring the evolution of Soloviev’s philosophical system, and offering detailed and nuanced analyses of the relationships of Soloviev's ideas with those of his great predecessors (Plato, Descartes, Spinoza, Leibniz, Kant, Hegel, Jewish Kabbala etc.)."

"This book is a welcome contribution to a growing body of literature on Russian sophiology. Weaving his narrative around Soloviev’s spiritual and intellectual biography, Oliver Smith offers a nuanced and erudite account of Soloviev’s metaphysics of all-unity. Smith successfully shows that at the core of Soloviev’s metaphysical project was a consistent integration of spiritual and material aspects of reality, epitomized in the incarnation."

This brilliant study of Russia’s greatest religious philosopher delivers much more than its title suggests...It encompasses the whole of Solovev’s philosophy; the spiritualization of matter is a part. Smith’s book, despite its modest claim to being about one part, is really about the whole. It conveys that whole effectively and powerfully.
