We have no written records of this almost animal-like stage, but studies of the various stages of civilization among extinct and living savages prove that such a stage has at one time existed. Man has not stepped into life as a highly civilized being, upon a command from the Creator, but has passed through a long, infinitely slow process of evolution, and in the ups and downs of wavering periods of development, and in a constant process of differentiation, in all climes and in all quarters of the globe, has passed through many stages until finally climbing the height of his present civilization. And while in some parts of the globe great nations represent the most advanced stage of civilization, we find other peoples in various places representing varied stages of development. These present to us a vivid picture of our own past, and point out to us along which roads humanity has traveled in its long course of evolution. If we shall at some time succeed in establishing general and definite aspects according to which sociological investigations shall be conducted, an abundance of facts will result, destined to cast a new light upon the relations of men in the past and the present. Events will then seem comprehensible and natural, that at present are quite beyond our comprehension, and that superficial critics frequently condemn as irrational, sometimes even as immoral. Scientific researches, commenced by Backofen, and since continued by a considerable number of learned men as Taylor, MacLennon, Lubbock and others, have gradually lifted the veil from the earliest history of our race. These investigations were elaborated by Morgan’s able book, and to this again Frederick Engels has added a number of historic facts, economic and political in character. Recently these researches have been partly confirmed and partly corrected by Cunow.[2] The clear and vivid descriptions given by Frederick Engels in his splendid work, that is founded upon Morgan’s investigations, have cast a flood of light upon many factors in the histories of peoples representing various stages of development; factors that until that time had seemed irrational and incomprehensible. They have enabled us to obtain an insight into the gradual upbuilding of the social structure. As a result of such insight we perceive that our former conceptions in regard to marriage, family and state, have been founded upon utterly false premises. But whatever has been proven concerning marriage, family and state, is equally true in regard to the position of woman, which, in the various stages of social development, has differed radically from what is supposed to be woman’s “eternal” position.
