Jaynes's one and only book, published in 1976, is ''[[The Origin of Consciousness in the Breakdown of the Bicameral Mind]]''. The topic of [[consciousness]] – "the human ability to introspect"{{sfnp|Kuijsten|2016|loc=Introduction}} – is introduced by reviewing prior efforts to explain its problematic nature: those efforts, as one of Jaynes's early critics has acknowledged, add up to a "spectacular history of failure".{{sfnp|Jones|1979|p=2}} Abandoning the assumption that consciousness is innate, Jaynes explains it instead as a learned behavior that "arises&nbsp;... from language, and specifically from metaphor."{{sfnp|Jones|1979|p=4}} With this understanding, Jaynes then demonstrates that ancient texts and archeology can reveal a history of human mentality alongside the histories of other cultural products. His analysis of the evidence leads him not only to place the origin of consciousness during the [[2nd millennium BCE]] but also to hypothesize the existence of an older non-conscious "mentality that he calls the bicameral mind, referring to the brain's two hemispheres".{{sfnp|Kuijsten|2006|loc=Introduction}}

After publishing {{em|[[The Origin of Consciousness in the Breakdown of the Bicameral Mind]]}}, Jaynes was frequently invited to speak at conferences and as a guest lecturer at other universities. In 1984, he was invited to give the plenary lecture at the [[Wittgenstein Symposium]] in Kirchberg, Austria. He gave six major lectures in 1985 and nine in 1986. He was awarded an [[honorary PhD]] by [[Rhode Island College]] in 1979 and another from [[Elizabethtown College]] in 1985.{{sfnp|Woodward|Tower|2006}}

Jaynes wrote an extensive afterword for the 1990 edition of his book,{{sfnp|Jaynes|2000|loc=Afterword}} in which he addressed criticisms and clarified that his theory has four separate hypotheses: 1) consciousness is based on and accessed by language; 2) the non-conscious [[Bicameralism (psychology)|bicameral mind]] is based on verbal hallucinations; 3) the breakdown of bicameral mind precedes consciousness, but the dating is variable; 4) the 'double brain' of bicamerality is based on the two [[cerebral hemisphere|hemispheres of the cerebral cortex]] being organized differently from today's [[Lateralization of brain function|functional lateralization]]. He also expanded on the impact of consciousness on imagination and memory, notions of the [[self]], emotions, anxiety, guilt, and sexuality.
