Vladimir Solov'ev's fundamental philosophical ideas

I recall that Solov'ev was Russia's first professional philosopher and present the most important currents and concepts of his many-sided theoretical edifice. Solov'ev conceived philosophy in a very broad sense of the term, for which reason his thinking comprises metaphysics no less than theology, ecclesiology, history, and sociology. I show how Solov'ev sought constantly to bring these diverse elements into agreement with one another for the sake of a consistent systematic project, how he attempted to synthesize numerous oppositions (including patriotism and universalism, humanism and theocentrism).
