Ecstasy

About this time I had the good fortune of locating a supply of ecstasy. True to its name, ecstasy promotes a kind of euphoric jitteryness, in which it is just a thrill to be alive! Every fiber of your being is just quivering with energy. But ecstasy also has some interesting perceptual manifestations. In the first place there is a kind of jitteryness across the whole visual field. And this jitteryness is so pronounced that it can manifest itself in your eyeballs, that jitter back and forth at a blinding speed. If you relax, and just let the jitters take over, the oscillations of your eyes will blur the whole scene into a peculiar double image. But if you concentrate, and focus, the ocular jitter can be made to subside, and thus become less noticeable or bothersome. One of my friends got the ocular jitters so bad that he could not control them, and that prevented him from having a good time. That was the last time he took ecstasy. I however found it enchanting. And I analyzed that subtle jitteryness more carefully. It was not caused exclusively by jittering of the eyeball, but different objects in the perceived world also seemed to jitter endlessly between alternate states. In fact, all perceived objects jittered in this manner, creating a fuzzy blur between alternate states. This was interesting for a psychonaut! It seemed to me that I could see the mechanism of my visual brain sweeping out the image of my experience right before my eyes, like the flying spot of light that paints the television picture on the glowing phosphor screen. The refresh rate of my visual mechanism had slowed to such a point as to make this sweep visible to me. Very interesting indeed!

Candy-Flipping

Having access simultaneously to ecstasy and LSD, I tried my hand at the practice known in the drug literature as “candy flipping”, that is, taking ecstasy and LSD in combination. The combination is so unique and different from the experience of either drug in isolation, that it has earned its own unique name. Under LSD and ecstasy I could see the flickering blur of visual generation most clearly. And I saw peculiar ornamental artifacts on all perceived objects, like a Fourier representation with the higher harmonics chopped off. LSD by itself creates sharply detailed ornamental artifacts, like a transparent overlay of an ornamental lattice or filigree pattern superimposed on the visual scene, especially in darkness. Ecstasy smooths out those sharp edges and blurs them into a creamy smooth rolling experience. I would sometimes feel some part of my world suddenly bulging out to greater magnification, like a fish-eye lens distortion appearing randomly in space, stretching everything in that portion of space like a reflection in a funhouse mirror. But it was not an actual bulging that changed the shape of the visual world, but more of a seeming bulging, that was perceived in an invisible sense without actual distortion of the world. For example one time I was putting on my boots to go outside, and as I reached down to pull on a boot, I suddenly got the impression that my leg grew to ten times its normal length, but I could still reach my boot because my arms had also grown by the same proportion, as had the whole space in that part of the room. Nothing actually looked any different after this expansion, it was just my sense of the scale of the world that had undergone this transformation, and even as I contemplated this, and finished securing my boot, the world shrank down gradually back to its normal scale again and the distortion vanished.

I have theorized that the way that ecstasy achieved its creamy smoothness is by dithering or alternating so fast between perceptual alternatives as to blur them together, like a spinning propellor that appears as a semi-transparent disc. At this level of observation I was unable to get my co-trippers to see the features that I was seeing. I would ask them when they saw that line of trees, did they not see illusory projections, like a transparent overlay of vectors projecting up from the trees into the blue sky that I could see? They did not see these things. So don’t expect to see what I see when I take LSD and ecstasy. I report my observations as I experience them, but observation of the psychedelic experience is every bit as subjective and variable as any phenomenological observation of our own experience. What stands out for one observer might remain completely obscure to another.

But the features I observed in my psychedelic experience all pointed toward a single self-consistent explanation of the mechanism of experience. It appears that the spatial structure of visual experience is swept out by some kind of volumetric imaging mechanism with a periodic refresh scan, not unlike the principle of television imagery, but extended into three dimensions. This was interesting indeed!

• Quantifying Bliss – which proposes a model from first principles to explain the structural properties of an experience that makes it feel good, bad, mixed, or neutral (i.e. valence). It then derives from this model precise, empirically testable predictions for what really good experiences should look like. Specifically, MDMA euphoria is postulated to be the result of a high level of consonance between connectome-specific harmonic waves.
• A Future for Neuroscience – which discusses the broad implications of a harmonic resonance theory of brain function for neuroscience, including new ways to conceptualize personality, and exotic states of consciousness.
• The Pseudo-Time Arrow – which discusses a particular physicalist model to explain the experience of time by examining the patterns of *implicit causality* in networks of local binding (these terms are defined there). The bottom line being: each moment of experience contains time implicitly embedded in its geometric structure. Psychedelics, MDMA, and their combination would each have unique signature structural effects along the arrow of pseudo-time.

Taken together, these articles would provide an explanation for why MDMA has a uniquely euphoric effect. In particular, Lehar’s point that MDMA’s generalized jitteryness/dithering smooths out the sharp edges of an LSD experience would show up as the harmonization/regularization of the relationship between time-slices along the pseudo-time arrow of experience. The Symmetry Theory of Valence can then be applied in the resulting network of local binding after MDMA’s smoothing effect, leading to the peculiar insight that MDMA’s euphoric effects come from the symmetrification of experience along the axis of experiential time. The creaminess of experience produced by MDMDA that Lehar talks about feels very good precisely because it is the phenomenal character of a dissonance-free state of consciousness. Hence, the fundamental nature of pleasure is not behavioral reinforcement, the maximization of utility according to one’s utility function, or expected surprise minimization; pleasure is more fundamental and low-level than any of those properties. Pleasure, we predict, shall correspond to the degree and intensity of energized symmetries present in a bound moment of experience, and MDMA phenomenology is a clear example of what it looks like to optimize for this property.
