     [Gk episte-me- knowledge, fr. epistanai to understand, know,] fr.

      grounds of knowledge esp. with reference to its limits and
      validity 

My adoption of "experimental epistemology" as a description of what I am doing has been influenced by the life and work of Warren McCulloch. The "experimental" bit in that phrase stands, in my case, for psychophysics and for computational modeling (there is nothing like having to actually program a model to force you to face the music).
