To be a follower needs only the passive recognition of the idea. To be a member means to represent that idea and fight for it. From ten followers one can have scarcely more than two members. To be a follower simply implies that a man has accepted the teaching of the movement; whereas to be a member means that a man has the courage to participate actively in diffusing that teaching in which he has come to believe.

Because of its passive character, the simple effort of believing in a political doctrine is enough for the majority, for the majority of mankind is mentally lazy and timid. To be a member one must be intellectually active, and therefore this applies only to the minority.
