1.Semantic information is valuable—misinformation and disinformation are either pathologies or parasitic perversions of the default cases. 2.The value of semantic information is receiver-relative and not measurable in any nonarbitrary way but can be confirmed by empirical testing. 3.The amount of semantic information carried or contained in any delimited episode or item is also not usefully measurable in units but roughly comparable in local circumstances. 4.Semantic information need not be encoded to be transmitted or saved.
