Mass assemblies are also necessary for the reason that, in attending them, the individual who felt himself formerly only on the point of joining the new movement, now begins to feel isolated and in fear of being left alone as he acquires for the first time the picture of a great community which has a strengthening and encouraging effect on most people. Brigaded in a company or battalion, surrounded by his companions, he will march with a lighter heart to the attack than if he had to march alone. In the crowd he feels himself in some way thus sheltered, though in reality there are a thousand arguments against such a feeling.
