Émile Durkheim envisioned 2 different systems of social solidarity: mechanical and organic (aka contractual). (The term organic was in reference to organs in a body.)
With mechanical solidarity, individuals are united via shared values and other social bonds. Society members, who perform similar tasks, develop a shared consciousness. Mechanical solidarity is found in farming communities.
Native American tribes prior to European conquest were bound together by mechanical solidarity. Their recent attempts to recapture this spirit of solidarity have been foiled by superimposition interference from the institutions of their occupiers: the dastardly white man.
Few societies are held together now via mechanical solidarity. One sterling outlier remains in the American Amish.
