I wish to introduce a model dating back to the Greek philosopher-scientist Aristotle that I believe is useful in understanding both the psychological and spiritual effects of psychedelic drugs. In this, I use the version that the medieval Jewish philosophers developed, especially that of Maimonides—a rabbi, philosopher, and physician who lived in Egypt in the 1200s. I am the first to admit the idiosyncratic nature of this model, but please bear with me, and I think you will see why I find it attractive.
Aristotle divided the mind into two “faculties,” or functions. One is the rational faculty, or intellect. The other is the imaginative faculty, or imagination.
The rational faculty is the location in the mind for abstractions, thoughts, beliefs, and concepts. Things that have no discernable form. That is, we do not see an idea, we think it. The rational faculty is where we experience concepts, remember them, and combine them in new ways. Mathematics is a good example of the contents and operations of the rational faculty. For the medievalists, nonphysical thoughts provided a link between our minds and a nonphysical God. The rational faculty is what distinguishes humans from “beasts.” It is the manifestation of our spiritual nature.
The imaginative faculty is the location of everything else. It contains “physical” information, such as sensations, body awareness, and emotions. As such, the philosophers believed that the imaginative faculty was physical, biological, something that we share with lower animals. The “imagination” in this system differs from the common definition of “imaginary,” “unreal,” “make-believe,” and the like. Instead, it is simply the location of everything nonabstract that exists in our minds. It is where we experience nonabstract contents, remember them, and create novel combinations such as works of art.
The medievalists proposed that the imaginative faculty, being biological in nature, was not especially amenable to change. They knew of no way to increase the function of the imagination. As they located it in the brain, this meant that the brain constrained the function of the imagination. The best one could do was to not degrade its function through an unhealthy lifestyle. The rational faculty, on the other hand, was amenable to growth and development through study and living a virtuous life. That virtuous life would also help maintain the health of the brain.
For Maimonides, the attainment of prophecy—the highest possible spiritual experience in the Hebrew biblical tradition—occurred with the “perfection” of the imagination and intellect working in concert. This was quite rare because of how infrequently one encountered a “perfected” brain, as well as the rigors of study and morality necessary to perfect the intellect.
In the case of the prophet, the perfection of the intellect and the imagination resulted in heightened receptivity to externally existent divine information. It was not a case of “influencing God” to communicate with the prophet. Rather, the state of the prophet made him/her more capable of receiving divine influence that was constantly everywhere.
Maimonides’s model proposes that divine influence stimulated the imagination from outside the person. The imagination then converted this influence into things one could perceive: visions, voices, feelings, and other “bodily” contents. Because of the divine source of the imagination’s contents, those contents contained divine information. A perfected imagination would allow for more clear and discernible contents than those one perceived via a weak, corrupted imagination.
Then, a perfected intellect would extract information from the perfectly perceived, divinely generated contents of the imagination. This information is now verbal, conceptual, abstract. A perfected intellect is also able to effectively communicate that information verbally to others. There are hundreds of examples of this process in the Hebrew Bible’s account of prophetic experience.
Here is how I see psychedelics fitting into this model. Up until now, we have been unable to significantly modify the biological imagination. We are born with a more or less well-developed brain. Our senses are only so sharp, our emotions only so refined. Psychedelics, however, may be a route to stimulating the imagination.
During my DMT work, I was impressed by how the psychedelic experience was much more “imaginative” than “intellectual.” Volunteers could describe in extraordinary detail the feelings, visions, emotions, and bodily properties of the experience. However, the quantity and novelty of the cognitive contents were relatively meager. The experiences simply confirmed or extended volunteers preexisting beliefs, or helped clarify personal problems, enhancing their meaning, imbuing them with a greater sense of truth and reality. I believe this is the result of a stimulated imagination. How one determines what is real ultimately relates to “how it feels.” It is a feeling, not a rational deduction. And feeling is in the domain of the imagination.
Thus, it seems as if DMT and other psychedelics stimulate the imagination more than the intellect. In this, they provide a tool to strengthen the imagination in a way that was not available to the medievalists.
There are two ways in which a “stimulated imagination” may impart new information to someone in the psychedelic state. One is the aforementioned heightened receptivity or sensitivity to spiritual information that surrounds us at all times. This is the basis of my “theoneurological” model of spiritual experience, an alternative to the top-down model of “neurotheology.” Neurotheology, the reigning model for the biology of spiritual experience, treats such experiences from a bottom-up perspective. The brain generates the impression of communicating with the divine, perhaps through the release of endogenous DMT through the activation of a brain reflex brought about by prayer. The top-down model, theoneurology, proposes that the world of spirit communicates with us through the brain. Endogenous DMT, from this perspective, allows formless divine information to become perceptible.
The better developed one’s intellect, the more capable one is in deciphering the contents of the stimulated imagination. This is where I see the role of the intellect—which our “set” contains—in determining what we learn from any psychedelic experience. On one hand, a trip may be primarily “imaginative”—an aesthetic experience—fun, exciting, interesting, and novel. Or it may be the source of more practical and enduring information if one possesses the intention, vocabulary, and similar tools to mine the newly rich imaginative contents.
