[...] Bolshevik thought draws its inspiration from the feeling of possession of the truth. In the eyes of Lenin, of Bukharin, of Preobrazhensky, dialectical materialism is both the law of human thought as well as that of the development of nature and of societies. Bolshevik thinking is grounded in the possession of the truth. The Party is the repository of truth, and any form of thinking that differs from it is a dangerous or reactionary error. Here lies the spiritual source of its intolerance. The absolute conviction of its lofty mission assures it of a moral energy quite astonishing in its intensity— and, at the same time, a clerical mentality which is quick to become Inquisitorial. Lenin’s “proletarian Jacobinism,” with its detachment and discipline both in thought and action, is eventually grafted upon the preexisting temperament of activists molded by the old regime, that is by the struggle against despotism. I am quite convinced that a sort of natural selection of authoritarian temperaments is the result. Finally, the victory of the revolution deals with the inferiority complex of the perpetually vanquished and bullied masses by arousing in them a spirit of social revenge, which in turn tends to generate new despotic institutions. I was witness to the great intoxication with which yesterday’s sailors and workers exercised command and enjoyed the satisfaction of demonstrating that they were now in power!
