Revolution, and particularly the social revolution, is not destruction but construction. This cannot be sufficiently emphasized, and unless we clearly realize it, revolution will remain only destructive and thereby always a failure. Naturally revolution is accompanied by violence, but you might as well say that building a new house in place of an old one is destructive because you have first to tear down the old one. Revolution is the culminating point of a certain evolutionary process: it begins with a violent upheaval. It is the rolling up of your sleeves preparatory to starting the actual work.
Indeed, consider what the social revolution is to do, what it is to accomplish, and you will perceive that it comes not to destroy but to build.
