CHAPTER VII MUTUAL AID AMONGST OURSELVES Popular revolts at the beginning of the State-period. Mutual Aid institutions of the present time. The village community; its struggles for resisting its abolition by the State. Habits derived from the village-community life, retained in our modern villages. Switzerland, France, Germany, Russia. The mutual-aid tendency in man has so remote an origin, and is so deeply interwoven with all the past evolution of the human race, that it has been maintained by mankind up to the present time, notwithstanding all vicissitudes of history. It was chiefly evolved during periods of peace and prosperity; but when even the greatest calamities befell men--when whole countries were laid waste by wars, and whole populations were decimated by misery, or groaned under the yoke of tyranny--the same tendency continued to live in the villages and among the poorer classes in the towns; it still kept them together, and in the long run it reacted even upon those ruling, fighting, and devastating minorities which dismissed it as sentimental nonsense. And whenever mankind had to work out a new social organization, adapted to a new phasis of development, its constructive genius always drew the elements and the inspiration for the new departure from that same ever-living tendency. New economical and social institutions, in so far as they were a creation of the masses, new ethical systems, and new religions, all have originated from the same source, and the ethical progress of our race, viewed in its broad lines, appears as a gradual extension of the mutual-aid principles from the tribe to always larger and larger agglomerations, so as to finally embrace one day the whole of mankind, without respect to its divers creeds, languages, and races.
