Custom in action : Ferdinand Tönnies's ontology of the normative

This paper deals with custom in action, namely, with the relationship between custom and action against the background of Amedeo Giovanni Conte’s nomotropism. Starting with Frerichs’ provocation of the peculiarity of saying ‘handeln nach der Sitte’ (acting according to custom) in favor of ‘sich handelnd nach was üblich ist’ (acting after what is usual), this paper will begin an exploratory research regarding the semantics and the ontology of custom to investigate the possibility of a nomotropic behavior in the field of custom. Therefore, this paper will quote, at first, Rudolf von Jhering’s theory, and, at second, Ferdinand Tönnies’ theory. In conclusion, this paper suggests that an inquiry into custom in action (and in particular Tönnies’ ontology of the normative) could benefit from the nomotropic categories of analysis – such as adeontic and deontic regularities.
