The Russian Revolution has interested the whole world in Russia and the Russian people. The peoples of the West are uneasy about the Communist experiment, accompanied as it is by a forced implanting of atheism such as the world has never yet known - an experiment carried on in a vast country which is little known to, and little understood by, the West. What must be of great interest is the psychological problem: How was it possible for Holy Russia to be turned into an arsenal of militant atheism? How is it that a people who are religious by their very structure and live exclusively by faith have proved to be such a fruitful field for anti-religious propaganda? To explain that, to understand Russian anti-religious psychology, one must have an insight into the religious psychology of the Russian people.
