 One of Anderson’s most audacious articles was the 1934 “Mind as Feeling” which attempts to work out exactly how mentality should be conceived as belonging to the spatio-temporal realm. Anderson believed that once we admit the spatial nature of mind or of anything mental, “Cartesianism goes” (JAA, Lectures on Reid, 1935.) The mental realm consists as much of situations as the natural and social world, so our knowledge of mind is on the same footing as the non-mental. He repudiates the Cartesian subject-object model which sees philosophy’s task as the study of the medium for knowledge understood as the relation whereby one entity reproduces within itself the essence or intrinsic characteristics of some other entity. There is no such medium for there are not different entities within space and time requiring such mediation. There is no “knower” conceived as a point of consciousness that has stepped outside history, outside of space and time. In our striving and grappling with illusions so as to come to terms with ourselves and the things around us we never step outside the movement of things, nor see behind the proposition; never reach outside the realm of propositional claim and counter-claim.
