In this article, the author analyzes the political ideas of P.I. Novgorod-rodtsev and I.A. Ilyin at an early and late creative stage. The point is that at an early stage, the political thoughts of the teacher and student were directed toward supporting the revolution. Later - they denied it. The author tries to determine the cause of such ideological variability. The author considers the political struggle and the ideology of scientists before and after 1917. These issues, in the era of global socio-political transfor- mations, turn out to be key.And the experience left in the creative heritage of scientists allows us once more to look at and evaluate the revolutionary events from February to October from the position of the teacher (PI Novgorodtsev) and the student (IA Il'in). Since before the revolution, scientists only philosophized about general state-political aspects. And on the eve and at the time of the revolutionary peri-ceti, they switched to all-Russian problems.
