Sets, Separation, and Frames

Resumen

The paper is devoted to analyzing, by using basic notions of set theory, the problem of the identification of law and the notion of a frame of meanings attributable to legal texts. The main results of the inquiry carried out in the paper are: 1) that only a neutral, non-evaluative, definition of law can do from a legal theoretical viewpoint; 2) that the concept of law should not be seen as referring to a unitary set of norms, but rather as referring to a plurality of sets and of results of operations on sets.
