Amedeo G. Conte’s paper Kanon is a philosophical analysis of the notion of regularity (regolarità, Regelmässigkeit, régularité). Conte distinguishes between four forms of regularity: (i) nomonomic regularity; (ii) nomophoric regularity; (iii) nomotropic regularity; (iv) nomological regularity. Nomonomic regularity is the regularity of actions which are performed for the sake of a rule, um einer Regel Willen (cf. Immanuel Kant’s phrase um des Gesetzes Willen). Nomophoric regularity is the regularity of the actions which are performed according to a rule, gemäss einer Regel (cf. Kant's phrase gemäss dem Gesetze). Nomotropic regularity is the regularity of the actions which are performed as a function of a rule. Nomological regularity is the regularity of the actions which are performed regularly, but without a rule. Nomonomic regularity, nomophoric regularity and nomotropic regularity are forms of nomic regularity (a nomic regularity is a rule-related regularity); nomological regularity is an anomic regularity (an anomic regularity is a regularity without rules).
