There are four basic levels of concern in Simmel's work: 1. The psychological workings of social life 2. The sociological workings of interpersonal relationships. 3. The structure of and changes in zeitgeist (i.e. the social and cultural "spirit") of his time. He would also adopt the principle of emergentism, the idea that higher levels of conscious properties emerge from lower levels. 4. The nature and inevitable fate of humanity.
