Three types of praxeological constraints on nomothetic power

This article concerns the types of praxeological constraints on nomo thetic power; that is, constraints that are inherent in the nature of the nomothetic act itself and exist independently of the norms in force in a specific system of norms. The praxeological constraints on nomothetic power are different in kind. In this sense, it is possible to draw a distinction among three different kinds of intrinsic constraints on the creation of rules: (i) hyletic constraints (that depend on the mate rial structure of things), (ii) eidetic constraints (that depend on the eidos of things), and (iii) logical constraints (that depend on the logic itself).
