Abstract.The starting point of deontic logic is the distinction between non‐normative necessity and normative necessity. The first part of the paper shows that the distinction between normative necessity and non‐normative necessity occurs already in Aristotle's Orgunon. The second part of the paper makes a further distinction within normative deon itself: The distinction between deontic deon and anankastic deon. Anankastic deon behaves differently from deontic deon in a very important respect: Deontic indifference has no anankastic counterpart.

Abstract.The paper offers a critical survey of two main sorts of problems hindering the possibility of conceiving deontic logic as a suitable account of the logical behaviour of (sentences expressing) legal norms. The notion of “legal norm” is viewed as the main source of the first sort of problems: (a) the typological variety of legal norms requires an account both of the differing logical behaviour of (sentences expressing) differing legal norms, and of the relations which might hold amon them; (b) (...) the ontologic, semantic, and epistemic features of legal norms shed doubt on the very attempt to figure out a logical analysis of (sentences expressing) legal norms. The notion of “systemic legal validity” is viewed as the main source of the second sort of problems: Deontic logic does not provide suitable logical tools to account for legal phenomena like enactment, derogation, and conflicts between legal norms which rely on systemic legal validity.

Edmund Husserl often characterizes essences and eidetic laws in normative terms. Many of his statements to this effect are however highly puzzling as they appear at odds with Husserl’s general understanding of normativity. In this paper I focus on this puzzle and I argue that we can reconcile most of the apparent tensions between these two dimensions of Husserl’s philosophical thought. In the first part of the paper, drawing on the contemporary literature on kinds of norms, I focus on Husserl’s (...) work on the varieties of normativity. I submit that, on his view, essences and eidetic laws are never intrinsically normative, and that not all essences and not all corresponding eidetic laws can function as norms for their instances. Crucially, however, I argue that, according to Husserl, essences and eidetic laws can function as norms for a range of the subject’s acts. In the second part of the paper I further examine this thesis, thus explaining in what sense Husserl thinks that essences and eidetic laws can have this function. I show that formal eidetic laws can engender deontic and evaluative norms for correct or rational judgments, evaluations, desires, and acts of the will. I also contend that material essences and material eidetic laws also have a normative function for judgments. I conclude that this shows how Husserl’s view makes room for norms that are not context-dependent or subjectively grounded. (shrink)
