It looks very much like it: Julian James, 'The Origin of Consciousness in the Breakdown of the Bicameral Mind' (see [1]), which influenced Neal Stephenson's writing of Snow Crash.
Scott Alexander wrote a critique of it beginning "Julian Jaynes’ The Origin Of Consciousness In The Breakdown Of The Bicameral Mind is a brilliant book, with only two minor flaws. First, that it purports to explains the origin of consciousness. And second, that it posits a breakdown of the bicameral mind. I think it’s possible to route around these flaws while keeping the thesis otherwise intact..." [2]. A response (which I have not yet read) can be found here [3].
