Abstract: The purpose of this paper is to determine what natural functors $ T:{\mathbf{A}} \to {\mathbf{X}}$ are $ (\mathcal{E},\mathfrak{M})$-topological, where $ {\mathbf{A}}$ is a subcategory of the category of proximity or uniform spaces and $ {\mathbf{X}}$ is an $ (\mathcal{E},\mathfrak{M})$-category. We give necessary and sufficient conditions under which a point separating family of continuous functions can be nicely lifted to a proximally continuous family. Proximities having a finest compatible uniform structure are characterized.
