This paper makes several uncommon claims. First, it suggests a theoretical approach, even though the theory comes with a clear methodology and implementation, so that we know what we do, how we do it, and why it is best to do it that way. Second, it pushes forward HARMS communication in natural language and explains why it is better that way. Third, it insists on the semantic approach so that all the HARMS agents "understand" (or even understand) what is going on--along with what is not. Fourth, most specifically and, hence, perhaps least importantly, it proposes one particular method of doing it, mildly hinting that some of its principles are unavoidable.
