87:1.3

The primitives feared sickness because they observed it was often a harbinger of death. If the tribal medicine man failed to cure an afflicted individual, the sick man was usually removed from the family hut, being taken to a smaller one or left in the open air to die alone. A house in which death had occurred was usually destroyed; if not, it was always avoided, and this fear prevented early man from building substantial dwellings. It also militated against the establishment of permanent villages and cities.
