There is, however, another aspect of Bolshevism from which I differ more fundamentally. Bolshevism is not merely a political doctrine; it is also a religion, with elaborate dogmas and inspired scriptures. When Lenin wishes to prove some proposition, he does so, if possible, by quoting texts from Marx and Engels. A full-fledged Communist is not merely a man who believes that land and capital should be held in common, and their produce distributed as nearly equally as possible. He is a man who entertains a number of elaborate and dogmatic beliefs--such as philosophic materialism, for example--which may be true, but are not, to a scientific temper, capable of being known to be true with any certainty. This habit, of militant certainty about objectively doubtful matters, is one from which, since the Renaissance, the world has been gradually emerging, into that temper of constructive and fruitful scepticism which constitutes the scientific outlook. I believe the scientific outlook to be immeasurably important to the human race. If a more just economic system were only attainable by closing men's minds against free inquiry, and plunging them back into the intellectual prison of the middle ages, I should consider the price too high. It cannot be denied that, over any short period of time, dogmatic belief is a help in fighting. If all Communists become religious fanatics, while supporters of capitalism retain a sceptical temper, it may be assumed that the Communists will win, while in the contrary case the capitalists would win. It seems evident, from the attitude of the capitalist world to Soviet Russia, of the Entente to the Central Empires, and of England to Ireland and India, that there is no depth of cruelty, perfidy or brutality from which the present holders of power will shrink when they feel themselves threatened. If, in order to oust them, nothing short of religious fanaticism will serve, it is they who are the prime sources of the resultant evil. And it is permissible to hope that, when they have been dispossessed, fanaticism will fade, as other fanaticisms have faded in the past. The present holders of power are evil men, and the present manner of life is doomed. To make the transition with a minimum of bloodshed, with a maximum of preservation of whatever has value in our existing civilization, is a difficult problem. It is this problem which has chiefly occupied my mind in writing the following pages. I wish I could think that its solution would be facilitated by some slight degree of moderation and humane feeling on the part of those who enjoy unjust privileges in the world as it is.
