Once such a movement has come into existence it may lay practical claim to certain priority rights. The natural course of things would now be that all those who wish to fight for the same objective as this movement is striving for should identify themselves with it and thus increase its strength, so that the common purpose in view may be all the better served. Especially men of superior intelligence must feel, one and all, that by joining the movement they are establishing precisely those conditions which are necessary for practical success in the common struggle. Accordingly it is reasonable and, in a certain sense, honest--which honesty, as I shall show later, is an element of very great importance--that only one movement should be founded for the purpose of attaining the one aim.
