The article discusses Georg Simmel's theorizing on the social in the light of his treatment of the 'dyad' and the 'triad', constellations of two and three elements. What makes the dyad and the triad particularly interesting is the fact that they express the difference between the primary intersubjectivity immanent to the individuals and the objectified social forms in numerical terms, as quantitatively determined. In the article, it is argued that in its basic, methodologically simplest form, the social amounts for Simmel to dyadic interaction between I and you, that can be conceptualized as 'being-with'. Nevertheless, a third element is always included also in the dyad, be it only as an excluded third. Therefore, it is claimed that in order to fully understand the dynamics of social relationships, one must look at the interplay of two socio-logics, bivalent and trivalent. The 'third' not only interrupts the supposedly immediate relation between the two elements of the dyad, but it is also capable of transforming it into a completely new figure: a social whole, a 'we', which obtains a supra-individual life independent of the individuals.
