Consciousness and the Bicameral Mind - The Julian Jaynes Society Podcast

"The story of Abraham and Isaac is a cornerstone of monotheism. God commands a father to sacrifice his only son, and the father obeys without a single word of protest. For millennia, this has been taught as the definitive model of unwavering religious faith. But we have to consider the possibility that Abraham wasn't 'choosing' to be faithful. If he lacked the psychological capacity to debate or choose, his immediate obedience takes on a different meaning..."Learn more by reading "Conversations on Consciousness and the Bicameral Mind," currently on sale for a limited time:https://www.amazon.com/Conversations-Consciousness-Bicameral-Mind-Interviews/dp/1737305534https://www.julianjaynes.org/book/conversations-on-consciousness-and-the-bicameral-mind/Video produced by Marcel Kuijsten using generative AI tools and reviewed by human editors for accuracy and clarity.

"In 1976, Princeton University psychologist Julian Jaynes published a thesis arguing that human consciousness is a recently learned process. Before its development, he claimed, our ancestors operated under a bicameral -- or two-chambered -- mentality, where stress-induced hallucinations directed their behavior. Jaynes's fourth hypothesis provided a specific neurological model for this process. ..."Learn more by reading "Conversations on Consciousness and the Bicameral Mind," currently on sale for a limited time:https://www.amazon.com/Conversations-Consciousness-Bicameral-Mind-Interviews/dp/1737305534https://www.julianjaynes.org/book/conversations-on-consciousness-and-the-bicameral-mind/Video produced by Marcel Kuijsten using generative AI tools and reviewed by human editors for accuracy and clarity.

The Myth of “Pure Consciousness” - The Belief in a Fundamental Psychic Process Hinders Progress in PsychologyBy Brian J. McVeighProduced by Marcel Kuijsten. Read by Michael R. Jacobs (⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.theungoogleable.com⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠, ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.youtube.com/@VoidDenizen⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠).“If understanding a thing is arriving at a familiarizing metaphor for it, then we can see that there always will be a difficulty in understanding consciousness. For it should be immediately apparent that there is not and cannot be anything in our immediate experience that is like immediate experience itself. There is therefore a sense in which we shall never be able to understand consciousness in the same way that we can understand things that we are conscious of” (Julian Jaynes, 1976, p. 53).I have often wondered why so many well-credentialed researchers continue to bark up the wrong tree in their quest to understand consciousness. Many reasons could be offered, but in a recent discussion on the “Julian Jaynes — The Origin of Consciousness in the Breakdown of the Bicameral Mind” Facebook page someone brought up Jaynes’s aforementioned quote. ...Read the complete text from this episode:https://www.julianjaynes.org/2022/10/18/the-myth-of-pure-consciousness/Learn more about Julian Jaynes's theory or become a member by visiting the Julian Jaynes Society at ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.julianjaynes.org⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠.

Julian Jaynes Is Not for the Intellectually Fainthearted — But Breaking Jaynesian Psychology Down into Four Hypotheses Makes Things EasierBy Brian J. McVeighProduced by Marcel Kuijsten.

Though the book made sense to me, I could see why people would reject its arguments. Nevertheless I assumed that once carefully explained, people may not agree but would at least be able to discern a certain logic behind Jaynesian psychology. How naïve I was.Read the complete text from this episode:https://www.julianjaynes.org/2022/06/07/julian-jaynes-is-not-for-the-intellectually-fainthearted/Learn more about Julian Jaynes's theory or become a member by visiting the Julian Jaynes Society at ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.julianjaynes.org⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠.

Disentangling Inner Speech, Self-dialogue, and Auditory Hallucinations: The Mind Is a Machine for Sociopsychological CommunicationBy Brian J. McVeighProduced by Marcel Kuijsten. Read by Michael R. Jacobs (⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.theungoogleable.com⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠, ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.youtube.com/@VoidDenizen⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠).How are inner speech, self-dialogue, auditory imagery, and hallucinations related? And what exactly are hallucinations? Some have suggested that hallucinations are caused by a monitoring defect in inner speech (also termed inner voice, silent speech, subvocal speech, covert speech, self talk, internal monologue, verbal thought, etc.) (Fernyhough, The Voices Within, 2016). Such a claim, however, ignores the overwhelming evidence concerning hallucinations before about 1000 BCE. Any theoretical linkage must take into account one crucial datum: hallucinations were central to normal sociopsychological functioning. Hallucinations, which were ubiquitous in the ancient world, were a mechanism for social control (until about the first millennium BCE). The “monitoring defect” hypothesis confuses matters: Rather than hallucinations resulting from a problem with inner speech, inner speech is a type of watered-down hallucination. This is why, arguably, for some an inner voice possesses agent-like properties or is accompanied by a felt presence, suggesting vestigial bicameral mentality.Read the complete text from this episode:https://www.julianjaynes.org/2021/10/26/disentangling-inner-speech-self-dialogue-and-auditory-hallucinations/Learn more about Julian Jaynes's theory or become a member by visiting the Julian Jaynes Society at ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.julianjaynes.org⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠.

History, Not Evolution, Is the Key Variable for Understanding Consciousness: The Temporal Extension Thesis and the Adaptive PsycheBy Brian J. McVeighProduced by Marcel Kuijsten. Read by Michael R. Jacobs (⁠⁠⁠⁠⁠⁠⁠⁠www.theungoogleable.com⁠⁠⁠⁠⁠⁠⁠⁠, ⁠⁠⁠⁠⁠⁠⁠⁠www.youtube.com/@VoidDenizen⁠⁠⁠⁠⁠⁠⁠⁠).The human mind is always adjusting, accommodating, and adopting resources from outside itself to expand and improve its capabilities. Such adaptation, if broadly understood, unfolds across different temporal spans. But a glaring weakness of mainstream research psychology is its almost complete neglect of a time-scale that would illuminate how the human mind changes over a few generations or several centuries.Read the complete text from this episode:https://www.julianjaynes.org/2021/09/15/history-not-evolution-key-variable-for-understanding-consciousness/Learn more about Julian Jaynes's theory or become a member by visiting the Julian Jaynes Society at ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠www.julianjaynes.org⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠.

Has Human Mentality Changed?Part 1: Neuroplasticity and Jaynesian PsychologyBy Brian J. McVeighProduced by Marcel Kuijsten. Read by Michael R. Jacobs (⁠⁠⁠⁠⁠⁠www.theungoogleable.com⁠⁠⁠⁠⁠⁠, ⁠⁠⁠⁠⁠⁠www.youtube.com/@VoidDenizen⁠⁠⁠⁠⁠⁠).The media and scientific journals give much attention to “neuroplasticity” (the brain’s innate ability to form and reorganize synaptic connections in response to learning or injury), “neurodiversity” (variations in the brain regarding sociability, learning, attention, mood, and other various mental functions), “neurotypical,” and “neuroatypical.” From an intellectual historical perspective these terms elicit interest because they call into question, at least in a very general sense, what has been a foundational concept of the social sciences: Psychic unity. Introduced by the anthropologist Adolf Bastian (1826‒1905), psychic unity was further conceptualized early in the twentieth century as an intellectual assault on racism by enlightened, well-meaning, anthropologists. Psychic unity is a universalist idea postulating that that human mentality is more or less the same everywhere; it challenged the previously dominant view of social Darwinism that viewed societies climbing a ladder of civilizational progress. At the top were late-nineteenth century industrially-advanced societies whose technological prowess was assumed to grant them superiority. In the case of northern European and American powers, it was assumed that their “white,” Christian identity explained their success (though Japan, which was not far behind the Euro-American sphere in terms of “progress,” obviously did not rely on white racialism and Christianity to account for its achievements). It was thought that less successful societies had not acquired the cognitive capabilities to compete with those higher up the ladder of civilization. The premises of psychic unity are still prevalent among not a few psychologists and configures assumptions that restrict research, despite recent interest in neuroplasticity and neurodiversity.Read the complete text from this episode:https://www.julianjaynes.org/blog/julian-jaynes-theory/has-human-mentality-changed-part-1/Learn more about Julian Jaynes's theory or become a member by visiting the Julian Jaynes Society at ⁠⁠⁠⁠⁠⁠⁠⁠www.julianjaynes.org⁠⁠⁠⁠⁠⁠⁠⁠.
