Ellis is a retired colonel in the U.S. Army who is transmitting his brochure (not present) on "Bovarysm: The Art-Philosophy of Jules de Gaultier". He notes that Gaultier is an idealist and BR is a neutral monist; however, he feels the two philosophies have some things in common. He comments on BR's interesting use of behaviourism as an instrument of philosophical investigation.

Ellis has reviewed BR's Philosophy, presumably in his journal.
