Abstract
The topic of this article is the convergence of the fundamental theoretical intuitions of two independent currents of Christian philosophy at the turn of the nineteenth and twentieth centuries. Italian Catholic spiritualism and the internally diversified current of the Russian religious philosophical Renaissance proved to be convergent in their ontological realism based on the metaphysics of cognition. This consonance undermines the stereotype about the total difference between the Russian Orthodox and the Western Catholic mentality. The article tries to show that these two denominations both drew inspiration from the Patristic heritage and that, contrary to all appearances, Russian religious philosophy owes much to the Augustinian tradition. The paper reminds the discovery of this convergence made by Vladimir Ern, and discusses certain elements of the teachings of Vladimir Solovyev and Evgenii Troubetzkoy in comparison with the basic philosophical intuitions of the Italian philosopher Antonio Rosmini.
