Ordinarily, it is desirable to avoid making individual mention of the separately indexed domains, ''P''<sub>''j''</sub> and ''Q''<sub>''j''</sub> for all ''j'' ∈ ''J''. Common strategies for getting around this trouble involve the introduction of additional domains, designed to encompass all the objects needed in given contexts. Toward this end, an adequate supply of intermediate domains, called the ''rudiments of universal mediation'' (RUM's), can be defined as follows: | Ordinarily, it is desirable to avoid making individual mention of the separately indexed domains, ''P''<sub>''j''</sub> and ''Q''<sub>''j''</sub> for all ''j'' ∈ ''J''.
