Abstract: We introduce the nonstandard concept of a monadic set and characterize diagonal and covering uniformities in terms of such sets. This formulation relates the two fundamental aspects of uniformities directly and obviates the need for bases. We illustrate the utility of our approach by showing that it leads to significant simplifications of the standard proofs characterizing pseudo-metrizable uniform and uniformizable topological spaces.
