Vladimir Solovyov (1853-1900), one of the greatest philosophers of the nineteenth century, was the founder of a tradition of Russian spirituality that brought together philosophy, mysticism, and theology with a powerful social message. A close friend of Dostoevsky, a Platonist, and a gnostic visionary, Solovyov was a prophet, having been granted three visions of Sophia, Divine Wisdom. He was also a poet and a profoundly Christian metaphysicist. His most important works include "Lectures on Divine Humanity; The Justification of the Good;" and "War, Progress, and the End of History."
