Newspapers, in every war, find some heroic figure whom they exploit as a coming dictator, and changes of leadership in the field apparently sometimes have reference to these popular currents. But a nation in love with its leader is strong in defense, and readily becomes aggressive, and this relation of mass to leader is of course one of the main foundations of military morale. The second universal social phenomenon of war is the greatly intensified feeling of solidarity as shown in comradeship and united feelings on the part of the people. This too is in part, and only in part, a protective reaction. The individual becomes safe by becoming a part of a whole which then alone seems to have real existence and true value. The individual loses himself in the whole, but the whole group also becomes absorbed and taken into the sphere of protection and interest of the individual. The individual becomes highly sensitive to everything that happens to the group, and peculiarly affected by the social mood of comradeship. This spirit of comradeship becomes one of the most conspicuous qualities of the social life in time of war. Comradeship in arms is of course the highest point of this social solidarity. The mass action, the close physical relationship, subjection to the same narrow routine and the common experiences of danger, induce social states that represent the most complete expression of pure social feeling, and excite moods which, upon occasion may reach the highest degree of ecstasy or intoxication and lead to acts of the most exalted heroism.
