TTHE BASIC UNIT OF SOCIAL ORGANIZATION is and has always been the family. Within the structure of the family, human beings love, mate, and reproduce. It is primarily the family that teaches the child, imparting values and customs that condition an individual’s behavior for a lifetime. The family is also an institution woven into the web of history, but that does not mean that the family is static. It evolves and changes, assuming different forms in different times and places. The eighteenth century witnessed such an evolution: patterns of marriage shifted and individuals adapted and conformed to the new and changing realities of the family unit.
