 Apart from Broad’s discussion, the main roots of eliminative materialism can be found in the writings of a number of mid-20th century philosophers, most notably  Wilfred Sellars,  W.V.O. Quine,  Paul Feyerabend,  and  Richard Rorty.  In his important 1956 article, “Empiricism and the Philosophy of Mind”, Sellars introduced the idea that our conception of mentality may be derived not from direct access to the inner workings of our own minds, but instead from a primitive theoretical framework that we inherit from our culture. While Sellars himself regarded this theoretical framework as empirically correct, his claim that our conception of the mind is theory-based, and at least in principle falsifiable, would be influential to later supporters of eliminativism.
