 While the Brothers Grimm had not yet distinguished between "Gemeinschaft" (community) and "Gesellschaft" (society), Ferdinand Tönnies (1855–1936) noted in his 1887 work "Gemeinschaft und Gesellschaft" that the two were mutually exclusive - he defined "community" as a form of mutual affirmation of the people in themselves as in their resources, their respective communities (such as their family) but as an understood purpose - as opposed to its mutual form as "society" in which the individual himself was a purpose, with a 'community' (e.g.a corporation) watching over his means.
