    The aim of this note is to delineate some new systems of logic which govern the interconnections between two kinds of obligation: moral obligation and legal obligation . In consequence, we shall have in such a logic two kinds of forbideness of premission, and of indifference, but obviously definable in terms of the two obligation operators and negation.
