From ought-to-be to ought-to-do
semantic investigation in Kelsen and Castañeda

Abstract: Accordingly to the polish legal philosopher Jerzy Wróblewski, although

lack, which corresponds to the non-characterization of its peculiar semantics,
the ought-to-be. In fact, Kelsen assumes explicitly in his Pure Theory of Law

It is so an unconcluded work, especially within philosophy of law, the
adequate description of the semantic basis of norms and normativity. For this

It seems that a valid and sharp analysis of this subject was undertaken
by Guatemalan philosopher Héctor-Néri Castañeda. Overcoming the long-term
discussion about the proper status of norms between prescriptions and proposi-
tions, Castañeda assume norms to be a species of the proposition gender and
proceed to a semantic correction: rather than belonging to the ought-to-be, as
maintained Kelsen and the deontic logic tradition, it seems that a most suitable
semantic basis for norms is the ought-to-do. This position has some roots in the
history of philosophy, that could be traced as far as to the autonomy of practical
reason in Aristotle, and as near as the recent development of the logic of action,
within which Castañeda’s proposal could be adjoined. As for the ought-to-do, it
