This reissue of the now classic "Sociological Worlds" (originally published in 1995) attempts to present a comprehensive picture of human social life--from the perspective of the "comparative-historical revolution" in sociology and presents some of the best theoretical and empirical work that is now being done by comparative-historical sociologists, as well as work by their close cousins, socio-cultural anthropologists. From this perspective, readers gain a picture of the major ways in which human societies differ. For this new library edition, Professor Sanderson has provided both a new preface and three contributions that did not appear in the original edition.
