Mechanical solidarity, according to Durkheim was based on social integration through similarities of belief and group structure. Hillier elaborated how this concept is related to space. In his view, mechanic solidarity preferred a segregated and dispersed space, and this suggests the non-spatial sodality, that many of the common techniques for emphasising the identity of social groups – insignia, ceremony, statuses, mythologies and so on – find their strongest realisation, most probably for the obvious reason that groups that lack spatial integration must use other, more conceptual means if they are to cohere as groups. See: Organic solidarity.
