Unlike the algebra of propositions, the theory of additive measures is not self-dual. are mapped onto the axioms (3) of the dual additive measures, which contradict (2). then a dual additive measure M represents degrees of disbelief. The two maps are analogous in so far as (7) assigns to each measure of belief m a dual It follows immediately that no additive measure can represent a state of complete ignorance. no additive measure can be its own dual, even in its contingent propositions only.10 While the mapped to the corresponding set of additive dual measures, {Mi}. ./cache/work_ig6yrm33wnh77o6z6dpnc7edbq.pdf ./txt/work_ig6yrm33wnh77o6z6dpnc7edbq.txt
