Put in another way, this means that in every great revolutionary movement that is of world importance the idea of this movement must always be spread abroad through the operation of propaganda. The propagandist must never tire in his efforts to make the new ideas clearly understood, inculcating them among others, or at least he must place himself in the position of those others and endeavour to upset their confidence in the convictions they have hitherto held. In order that such propaganda should have backbone to it, it must be based on an organization. The organization chooses its members from among those followers whom the propaganda has won. That organization will become all the more vigorous if the work of propaganda be pushed forward intensively. And the propaganda will work all the better when the

Hence the supreme task of the organizer is to see to it that any discord or differences which may arise among the members of the movement will not lead to a split and thereby cramp the work within the movement. Moreover, it is the duty of the organization to see that the fighting spirit of the movement does not flag or die out but that it is constantly reinvigorated and restrengthened. It is not necessary the number of members should increase indefinitely. Quite the contrary would be better. In view of the fact that only a fraction of humanity has energy and courage, a movement which increases its own organization indefinitely must of necessity one day become plethoric and inactive. Organizations, that is to say, groups of members, which increase their size beyond certain dimensions gradually lose their fighting force and

The greatest danger that can threaten a movement is an abnormal increase in the number of its members, owing to its too rapid success. So long as a movement has to carry on a hard and bitter fight, people of weak and fundamentally egotistic temperament will steer very clear of it; but these will try to be accepted as members the moment the party achieves a manifest success in the course of its development.

Now the greater and more revolutionary a doctrine is, so much the more active will be the spirit inspiring its body of members, because the subversive energy of such a doctrine will frighten way the chicken-hearted and small-minded bourgeoisie. In their hearts they may believe in the doctrine but they are afraid to acknowledge their belief openly. By reason of this very fact, however, an organization inspired by a veritable revolutionary idea will attract into the body of its membership only the most active of those believers who have been won for it by its propaganda. It is in this activity on the part of the membership body, guaranteed by the process of natural selection, that we are to seek the prerequisite conditions for the continuation of an active and spirited propaganda and also the victorious struggle for the success of the idea on which the movement is based.

All great movements, whether of a political or religious nature, owe their imposing success to the recognition and adoption of those principles. And no durable success is conceivable if these laws are not observed.
