In the present paper we model the Navya-Nyāya analysis of Vedic and secular injunctions and prohibitions by means of Giordani’s and Canavotto’s system ADL of dynamic deontic logic. Navya-Naiyāyikas analyze the meaning of injunctions and prohibitions by reducing them to plain indicative statements about certain properties whose presence or absence in the enjoined or prohibited action serves as a criterion for the truth or falsity of the “inducing” or “restraining knowledge”, a kind of qualificative cognition instilled in the recipient of (...) an injunction or prohibition. Thus, Navya-Naiyāyikas have found their own way to solve Jørgensen’s Puzzle concerning the very idea of a deontic logic as a tool to analyze arguments based on sentences which do not seem to be truth-apt. The teleological aspect of the Navya-Nyāya characterization of an enjoined or prohibited action can also give a clue to solutions of other puzzles and paradoxes which have beset the development of deontic logic in the West. A specific contrary-to-duty puzzle from the Indian tradition is related to the śyena, a malefic sacrifice meant for harming one’s enemy. The Vedic injunction to perform such a sacrifice runs counter to a religious practitioner’s duty not to harm a living being. In the present paper we examine the cogency of the very different solutions to this dilemma suggested by the Mīmāṃsaka Prabhākara on the one hand and the Navya-Naiyāyika Gaṅgeśa on the other hand.

This paper investigates whether or not cases of in concreto antinomies (ICAs for short, also called indirect antinomies, accidental antinomies, normative conflicts due to the facts, predicaments, or paranomies) can be predicted. I distinguish two main theoretical positions: “Prodetection” argues that we can predict in concreto antinomies; “unpredictability” argues that we cannot predict them.I exemplify the two positions by relying on a disagreement found in the literature; then, after reviewing that disagreement, I (i) provide arguments for both positions; (ii) highlight (...) the problematic issues for a definition of in concreto antinomy based on conceptual independence; (iii) point out some problems in Martínez Zorrilla’s threefold conception of normative conflicts; and (iv) advocate the need to introduce a case for “practically unpredictable” normative conflicts.

It is well known that systems of action deontic logic emerging from a standard analysis of permission in terms of possibility of doing an action without incurring in a violation of the law are subject to paradoxes. In general, paradoxes are acknowledged as such if we have intuitions telling us that things should be different. The aim of this paper is to introduce a paradox-free deontic action system by (i) identifying the basic intuitions leading to the emergence of the paradoxes (...) and (ii) exploiting these intuitions in order to develop a consistent deontic framework, where it can be shown why some phenomena seem to be paradoxical and why they are not so if interpreted in a correct way.
