Abstract
The most important concept of philosophy of history is con-sidered in connection with the contribution made by Karl Kantor, a well-known Russian philosopher, into solving the problem in his book titled “A Double Spiral of History. Historiosophia of Projectism”. Three revolutions of spirit which occurred in the history of society correspond to three paradigmatic projects of history. The 1st revolution of spirit was the phenomenon of Christ and the first project of history became Christianity. The 2nd revolution of spirit was Renaissance and the second project of histo-ry was an aesthetical art project. The third revolution of spirit was K. Marx and his scientific project of history which synthesizes, absorbs the religious and the aesthetical projects. The issue of an uncompromising, antagonistic struggle between history and sociocultural evolution is also discussed. The revolution of spirit strives for radical transformation of socium which resists transformation and thus leads to a historical deadlock. A way out of the dead-lock is inevitably connected with the beginning of a new revolution of spirit. The prospects of revolution of spirit continuing in contemporary world in-cluding Russia are also outlined.
