I think there is the influence of geometry in sociology. Simmel imagined society as a cosmic space. The complicated essence and direction of his work are infinite. However, any single point in it can be fixed and only one special way to develop, otherwise, the overall structure of this space will be changed. In other words, there is an inseparable link between micro-individual behavior and macro-social structure, and these linkages should be manifested through the process of social interaction.

So that is the geometric connection in the sociology. Everything in this world and any relationships can be explained by geometric.
