The article presents the theses of the report delivered at the round table «V.I. Lamansky and Academic slavophilism». In his work «Three worlds of the Asian-European continent» V.I. Lamansky suggested a description of the possible geopolitical structure of the world. In his opinion, due to the colonial politics of the British empire, centre of the Roman-German civilization will be transferred into the New World, while old Europe will acquire inferior role in world affairs. Greek-Slavic civilization will become politically strong, providing that it will be able to develop its civil life on the fundament of the Christian humanism and national self-consciousness. This picture appears to be close to the real state of the international affairs in the 20th century, which shows the productivity of Lamansky’s methodology.
