These movements, parties, religious groups, etc., originate entirely independently of one another out of the general urge of the time, and all with a view to working towards the same goal. It may seem a tragic thing, at least at first sight, that this should be so, because people are too often inclined to think that forces which are dispersed in different directions would attain their ends far more quickly and more surely if they were united in one common effort. But that is not so. For Nature herself decides according to the rules of her inexorable logic. She leaves these diverse groups to compete with one another and dispute the palm of victory and thus she chooses the clearest, shortest and surest way along which she leads the movement to its final goal.
