— daniel Dennett 28 Gregory cochran, a physicist and adjunct professor of anthropology at the University of Utah, wrote: "Genes affecting personality, reproductive strategies, cognition, are all able to change significantly over few-millennia time scales if the environment favors such change — and this includes. There is evidence that such change has occurred. On first reading, Breakdown seemed one of the craziest books ever written, but jaynes may have been on to something." 29 Author and historian of science morris Berman writes: " jaynes's description of this new consciousness is one of the best I have come across. " 30 Danish science writer Tor Nørretranders discusses jaynes's theory favorably in his 1991 book. 31 vague james McGilchrist who published a similar idea, accepts jayne's intention, but proposes that jayne's hypothesis was the opposite of what happened: I believe he jayne got one important aspect of the story back to front. His contention that the phenomena he describes came about because of a breakdown of the 'bicameral mind' so that the two hemispheres, previously separate, now merged is the precise inverse of what happened. 32 :262 Issues with jaynes' proposal edit wallpaper Epic of Gilgamesh as a counter-example edit As an argument against jaynes' proposed date of the transition from bicameralism to consciousness some critics have referred to the Epic of Gilgamesh. Citation needed early copies of the epic are many centuries older 33 than even the oldest passages of the Old Testament, 34 and yet it describes introspection and other mental processes that, according to jaynes, were impossible for the bicameral mind.
McVeigh (2007) maintains that many of the most frequent criticisms of jaynes' theory are either incorrect or reflect serious misunderstandings of jaynes' theory, especially jaynes' more precise definition of consciousness. Jaynes defines consciousness — in the tradition of Locke and Descartes — as " that which is introspectable ". Jaynes draws a sharp distinction between consciousness introspectable mind-space and other mental processes such as cognition, learning, sensation, and perception. McVeigh argues that this distinction is frequently not recognized by those offering critiques of jaynes' theory. 25 Individual scholars' comments edit richard Dawkins in The god Delusion (2006) wrote of The Origin of Consciousness in the Breakdown of the bicameral Mind : It is one of those books that is either complete rubbish or a work of consummate genius; Nothing. Probably the former, but I'm hedging my bets. 26 page needed The philosopher Daniel Dennett suggested that jaynes may have been wrong about some of his supporting arguments especially the importance he attached to hallucinations but that these things are not essential to his main thesis: 27 If we are going to use this. We are going to have to be speculative, but there is good and bad speculation, and this is not an unparalleled activity in science. Those scientists who have no taste for this sort of speculative enterprise will just have to stay in the trenches and do without it, while the rest of us risk embarrassing mistakes and have a lot of fun.

15 The pasa idea that language is a necessary component of subjective consciousness and more abstract forms of thinking has gained the support of proponents including Andy Clark, daniel Dennett, william. Calvin, merlin Donald, john Limber, howard Margolis, peter Carruthers, and José luis Bermúdez. 16 Williams (2010) 17 defended jaynes against the criticism of Block (1981). 18 clarification needed clarification needed Asaad shapiro (1987) 19 questioned why jaynes's theory was left out of a discussion on auditory hallucinations. The author's (1987) published response was:. .
Jaynes hypothesis makes for interesting reading and stimulates much thought in the receptive reader. It does not, however, adequately explain one of the central mysteries of madness: hallucination. (Moffic, 1987) 14 However Moffic's claim that there is no evidence for involvement of the right temporal lobe in auditory hallucination was incorrect, even at the time that he wrote. 20 21 More recently, a number of studies have provided more evidence of involvement of the right hemisphere in auditory hallucinations. The new evidence for jaynes's model of auditory hallucinations arising in the right temporal-parietal lobe and being transmitted to the left temporal-parietal lobe that these neuroimaging studies provide was specifically pointed out by Olin (1999) 22 and by Sher (2000). 23 For further discussion, see marcel kuijsten (2007).
Citation needed jaynes further argues that divination, prayer, and oracles arose during this breakdown period, in an attempt to summon instructions from the "gods" whose voices could no longer be heard. 3 The consultation of special bicamerally operative individuals, or of divination by casting lots and so forth, was a response to this loss, a transitional era depicted, for example, in the book of 1 Samuel. It was also evidenced in children who could communicate with the gods, but as their neurology was set by language and society they gradually lost that ability. Those who continued prophesying, being bicameral according to jaynes, could be killed. 6 7 Leftovers of the bicameral mind today, according to jaynes, include religion, hypnosis, possession, schizophrenia, and the general sense of need for external authority in decision-making. Citation needed reception edit popular reception edit An early (1977) reviewer considered jaynes's hypothesis worthy and offer conditional support, arguing the notion deserves further study.

Dick, terrence McKenna, and david Bowie all cited the book as an influence. 13 Scholarly reactions edit jaynes's hypothesis remains controversial. The primary scientific criticism has been that the conclusions drawn by jaynes had no basis in neuropsychiatric fact. 14 According to jaynes, language is a necessary, but not a sufficient condition for consciousness: Language existed thousands of years earlier, but consciousness could not have emerged without language.

Full citation essay needed As support for jaynes's argument, these command hallucinations are little different from the using commands from gods which feature prominently in ancient stories. 3 Indirect evidence supporting jaynes's theory that hallucinations once played an important role in human mentality can be found in the recent book muses, madmen, and Prophets: Rethinking the history, science, and meaning of Auditory hallucination by daniel Smith. 5 Breakdown of bicameralism edit jaynes theorized that a shift from bicameralism marked the beginning of introspection and consciousness as we know it today. According to jaynes, this bicameral mentality began malfunctioning or "breaking down" during the 2nd millennium BCE. He speculates that primitive ancient societies tended to collapse periodically: for example, egypt's Intermediate periods, as well as the periodically vanishing cities of the mayas, as changes in the environment strained the socio-cultural equilibria sustained by this bicameral mindset. The Bronze age collapse of the 2nd millennium bce led to mass migrations and created a rash of unexpected situations and stresses which required ancient minds to become more flexible and creative. Self-awareness, or consciousness, was the culturally evolved solution to this problem. This necessity of communicating commonly observed phenomena among individuals who shared no common language or cultural upbringing encouraged those communities to become self-aware to survive in a new environment. Thus consciousness, like bicamerality, emerged as a neurological adaptation to social complexity in a changing world.
3 This adaptation to the village communities of 100 individuals or more formed the core of religion. Unlike today's hallucinations, the voices of ancient times were structured by cultural norms to produce a seamlessly functioning society. Jaynes inferred that these "voices" came from the right brain counterparts of the left brain language centres; specifically, the counterparts to wernicke's area and Broca's area. These regions are somewhat dormant in the right brains of most modern humans, but jaynes noted that some thesis studies show that auditory hallucinations correspond to increased activity in these areas of the brain. 3 jaynes notes that even at the time of publication there is no consensus as to the cause or origins of schizophrenia. Jaynes argues that schizophrenia is a vestige of humanity's earlier bicameral state. 3 Recent evidence shows that many schizophrenics do not just hear random voices but experience " command hallucinations " instructing their behavior or urging them to commit certain acts.
took an interdisciplinary approach, drawing data from many different fields. 3 jaynes asserted that, until roughly the times written about in Homer 's Iliad, humans did not generally have the self-awareness characteristic of consciousness as most people experience it today. Rather, the bicameral individual was guided by mental commands believed to be issued by external " gods " — commands which were recorded in ancient myths, legends and historical accounts. This is exemplified not only in the commands given to characters in ancient epics but also the very muses of Greek mythology which "sang" the poems. According to jaynes, the ancients literally heard muses as the direct source of their music and poetry. Jaynes asserts that in the Iliad and sections of the Old Testament no mention is made of any kind of cognitive processes such as introspection, and there is no apparent indication that the writers were self-aware. Jaynes suggests, the older portions of the Old Testament (such as the book of Amos ) have few or none of the features of some later books of the Old Testament (such as Ecclesiastes ) as well as later works such as Homer's Odyssey, which. 3 In ancient times, jaynes noted, gods were generally much more numerous and much more anthropomorphic than in modern times, and speculates that this was because each bicameral person had their own "god" who reflected their own desires and experiences. 4 he also noted that in ancient societies the corpses of the dead were often treated as though still alive (being seated, dressed, and even fed) as a form of ancestor worship, and jaynes argued that the dead bodies were presumed to be still living.
Contents, the Origin of Consciousness edit, jaynes uses governmental bicameralism as a metaphor to describe a mental state in which the experiences and memories of the right hemisphere of the brain are transmitted to the left hemisphere via auditory hallucinations. The metaphor is based on the idea of lateralization of brain function although each half of a normal human brain is constantly communicating with the other through the corpus callosum. The metaphor is not meant to imply that the two halves of the bicameral brain were "cut off" from each other but that the bicameral mind was experienced as a different, non-conscious mental schema wherein volition in the face of novel stimuli was mediated through. Bicameral mentality edit, bicameral mentality would be non-conscious in its inability to reason and articulate about mental contents through meta-reflection, reacting without explicitly realizing and without the meta-reflective ability to give an account of why one did. The bicameral mind would thus lack metaconsciousness, autobiographical memory, and the capacity for executive "ego functions" such as deliberate mind-wandering and conscious introspection of mental content. When bicamerality as a method of social control was no longer adaptive in complex civilizations, this mental model was replaced by you the conscious mode of thought which, jaynes argued, is grounded in the acquisition of metaphorical language learned by exposure to narrative practice. According to jaynes, ancient people in the bicameral state of mind would have experienced the world in a manner that has some similarities to that of a schizophrenic. Rather than making conscious evaluations in novel or unexpected situations, the person would hallucinate a voice or "god" giving admonitory advice or commands and obey without question: One would not be at all conscious of one's own thought processes per. Research into " command hallucinations " that often direct the behavior of those labeled schizophrenic, as well as other voice hearers, supports jaynes's hypothesis.
