I designate as the content—the materials, so to speak—of sociation everything that is present in individuals (the immediately concrete loci of all historical reality)—drive, interest, purpose, inclination, psychic state, movement—everything that is present in them in such a way as to engender or mediate effects upon others or to receive such effects. In themselves, these materials which fill life, these motivations which propel it, are not social. Strictly speaking, neither hunger nor love, work nor religiosity, technology nor the functions and results of intelligence, are social. They are factors in sociation only when they transform the mere aggregation of isolated individuals into specific forms of being with and for one another, forms that are subsumed under the general concept of interaction.

DEFINE: Simmel distinguishes 'content' (the raw materials of life) from the social: content is not inherently social, only becoming so through interaction with others.
