I was going to post the following in the George Hanson "trickster" thread, but it connects with comments made by
@Burnt State in this Paracast episode, and with LCs comments. Maybe at some point a single thread to discuss this approach will materialize.
Some of us have discussed in various forum threads the similarities between abduction, close encounter, NDE, hallucinogen/entheogen, meditative, psychotic/mystical, and dream experiences. Essentially, they are all altered states of consciousness.
Often, the Trickster is referred to a change agent. A mechanism that causes -- or perhaps manifests -- during times of system destabilization. During his Paracast session, Burnt State noted how historically individuals who entered these altered states were shaman; individuals who used their ability to access altered states for the good of their community. In general, historically, there seems to have been much more openness, acceptance, and value of altered states and the knowledge and insights that could/can be gained from them. (It might even be argued that the use of hallucinogens/entheogens was historically more integrated into human cultures.)
While it doesn't explain those cases in which external stimuli have been documented, it's possible that both exogenous and endogenous chemicals and the altered subjective states/experiences which they catalyze in humans may be an
evolutionarily adaptive mechanism that brings novel information/knowledge into human culture. In other words, this noted capacity for humans to experience self-initiated and spontaneous altered states may be an adaptive mechanism.
Or, for those who disdain reductive explanations, it may be a mechanism that was bestowed upon humans by some Other(s) for the same purpose: to advance the species/culture.
With that in mind, I found the following commentary very interesting. It comes from a long read article from the New Yorker about recent psilocybin (Magic Mushroom) trials for treatment of anxiety in individuals with terminal cancer being conducted at Johns Hopkins University School of Medicine and New York University. Although the entire article is excellent and I recommend reading it, the comments of interest come from neuroscientist Carhart-Harris.
I've underlined the juicy bits for the tldr crowd.
“If the only way we can access the unconscious mind is via dreams and free association, we aren’t going to get anywhere,” he said. “Surely there must be something else.” One day, he asked his seminar leader if that might be a drug. She was intrigued. He set off to search the library catalogue for “LSD and the Unconscious” and found “Realms of the Human Unconscious,” by Stanislav Grof. “I read the book cover to cover. That set the course for the rest of my young life.” ...
When, in 2010, Carhart-Harris first began studying the brains of volunteers on psychedelics, neuroscientists assumed that the drugs somehow excited brain activity—hence the vivid hallucinations and powerful emotions that people report. But when Carhart-Harris looked at the results of the first set of fMRI scans—which pinpoint areas of brain activity by mapping local blood flow and oxygen consumption—he discovered that the drug appeared to substantially reduce brain activity in one particular region: the “default-mode network.”
The default-mode network was first described in 2001, in a landmark paper by Marcus Raichle, a neurologist at Washington University, in St. Louis, and it has since become the focus of much discussion in neuroscience. The network comprises a critical and centrally situated hub of brain activity that links parts of the cerebral cortex to deeper, older structures in the brain, such as the limbic system and the hippocampus.
The network, which consumes a significant portion of the brain’s energy, appears to be most active when we are least engaged in attending to the world or to a task. It lights up when we are daydreaming, removed from sensory processing, and engaging in higher-level “meta-cognitive” processes such as self-reflection, mental time travel, rumination, and “theory of mind”—the ability to attribute mental states to others. Carhart-Harris describes the default-mode network variously as the brain’s “orchestra conductor” or “corporate executive” or “capital city,” charged with managing and “holding the entire system together.” It is thought to be the physical counterpart of the autobiographical self, or ego.
“The brain is a hierarchical system,” Carhart-Harris said. “The highest-level parts”—such as the default-mode network—“have an inhibitory influence on the lower-level parts, like emotion and memory.” He discovered that blood flow and electrical activity in the default-mode network dropped off precipitously under the influence of psychedelics, a finding that may help to explain the loss of the sense of self that volunteers reported. (The biggest dropoffs in default-mode-network activity correlated with volunteers’ reports of ego dissolution.) Just before Carhart-Harris published his results, in a 2012 paper in Proceedings of the National Academy of Sciences, a researcher at Yale named Judson Brewer, who was using fMRI to study the brains of experienced meditators, noticed that their default-mode networks had also been quieted relative to those of novice meditators. It appears that, with the ego temporarily out of commission, the boundaries between self and world, subject and object, all dissolve. These are hallmarks of the mystical experience.
If the default-mode network functions as the conductor of the symphony of brain activity, we might expect its temporary disappearance from the stage to lead to an increase in dissonance and mental disorder—as appears to happen during the psychedelic journey. Carhart-Harris has found evidence in scans of brain waves that, when the default-mode network shuts down, other brain regions “are let off the leash.” Mental contents hidden from view (or suppressed) during normal waking consciousness come to the fore: emotions, memories, wishes and fears. Regions that don’t ordinarily communicate directly with one another strike up conversations (neuroscientists sometimes call this “crosstalk”), often with bizarre results. Carhart-Harris thinks that hallucinations occur when the visual-processing centers of the brain, left to their own devices, become more susceptible to the influence of our beliefs and emotions. ...
In “The Doors of Perception,” Aldous Huxley concluded from his psychedelic experience that the conscious mind is less a window on reality than a furious editor of it. The mind is a “reducing valve,” he wrote, eliminating far more reality than it admits to our conscious awareness, lest we be overwhelmed. “What comes out at the other end is a measly trickle of the kind of consciousness which will help us to stay alive.” Psychedelics open the valve wide, removing the filter that hides much of reality, as well as dimensions of our own minds, from ordinary consciousness. Carhart-Harris has cited Huxley’s metaphor in some of his papers, likening the default-mode network to the reducing valve, but he does not agree that everything that comes through the opened doors of perception is necessarily real. The psychedelic experience, he suggests, can yield a lot of “fool’s gold.”
Nevertheless, Carhart-Harris believes that the psychedelic experience can help people by relaxing the grip of an overbearing ego and the rigid, habitual thinking it enforces. The human brain is perhaps the most complex system there is, and the emergence of a conscious self is its highest achievement. By adulthood, the mind has become very good at observing and testing reality and developing confident predictions about it that optimize our investments of energy (mental and otherwise) and therefore our survival. Much of what we think of as perceptions of the world are really educated guesses based on past experience (“That fractal pattern of little green bits in my visual field must be a tree”), and this kind of conventional thinking serves us well.
But only up to a point. In Carhart-Harris’s view, a steep price is paid for the achievement of order and ego in the adult mind. “We give up our emotional lability,” he told me, “our ability to be open to surprises, our ability to think flexibly, and our ability to value nature.” The sovereign ego can become a despot. This is perhaps most evident in depression, when the self turns on itself and uncontrollable introspection gradually shades out reality. In “The Entropic Brain,” a paper published last year in Frontiers in Human Neuroscience, Carhart-Harris cites research indicating that this debilitating state, sometimes called “heavy self-consciousness,” may be the result of a “hyperactive” default-mode network. The lab recently received government funding to conduct a clinical study using psychedelics to treat depression.
Carhart-Harris believes that people suffering from other mental disorders characterized by excessively rigid patterns of thinking, such as addiction and obsessive-compulsive disorder, could benefit from psychedelics, which “disrupt stereotyped patterns of thought and behavior.” In his view, all these disorders are, in a sense, ailments of the ego. He also thinks that this disruption could promote more creative thinking. It may be that some brains could benefit from a little less order." ...
Once again, humans may simply be reinventing a "technology" that nature has already perfected over millennia of evolution. Spontaneous, endogenously caused altered,
tricksterish states may be an intrinsic mechanism of the human (and other) species that promotes change, survival, and potentially progress.
