On the one hand, we have the mass; on the other, its historic goal, located outside of existing society. On one hand, we have the day-to-day struggle; on the other, the social revolution. It follows that this movement can best advance by tacking betwixt and between the two dangers by which it is constantly being threatened. One is the loss of its mass character; the other, the abandonment of its goal. One is the danger of sinking back to the condition of a sect; the other, the danger of becoming a movement of bourgeois social reform.
The more that social democracy develops, grows, and becomes stronger, the more the enlightened masses of workers will take their own destinies, the leadership of their movement, and the determination of its direction into their own hands.
The self-discipline of the Social Democracy is not merely the replacement of the authority of bourgeois rulers with the authority of a socialist central committee. The working class will acquire the sense of the new discipline, the freely assumed self-discipline of the Social Democracy, not as a result of the discipline imposed on it by the capitalist state, but by extirpating, to the last root, its old habits of obedience and servility.
