Building up to an Internal Family Systems model

Have you read Minsky's _Society of Mind_? It is an AI-flavored psychological model of subagents that draws heavily on psychotherapeutic ideas. It seems quite similar in flavor to what you propose here. It inspired generations of students at the MIT AI Lab (although attempts to code it never worked out).

My attempt to explain Looking, insight meditation, and enlightenment in non-mysterious terms

Quote from Richard Feynman explaining why there are no objects here.

I've begun a STEM-compatible attempt to explain a "no objectively-given objects" ontology in "Boundaries, objects, and connections." That's supposed to be the introduction to a book chapter that is extensively drafted but not yet polished enough to publish.

Really glad you are working on this also!

Looking and the no-self

I would not say that selves don't exist (although it's possible that I have done so somewhere, sloppily).

Rather, that selves are both nebulous and patterned ("empty forms," in Tantric terminology).

Probably the clearest summary of that I've written so far is "Selfness," which is supposed to be the introduction to a chapter of the Meaningness book that does not yet otherwise exist.

Renouncing the self is characteristic of Sutrayana.

Looking and the no-self

[FWOMP Summoned spirit appears in Kaj's chalk octogram. Gouts of eldritch flame, etc. Spirit squints around at unfamiliar environment bemusedly. Takes off glasses, holds them up to the candlelight, grimaces, wipes glasses on clothing, replaces on nose. Grunts. Speaks:]

Buddhism is a diverse family of religions, with distinct conceptions of enlightenment. These seem to be quite different and contradictory.

According to one classification of disparate doctrines, Buddhism can be divided into Vajrayana (Tantra plus Dzogchen) and Sutrayana (everything else, except maybe Zen). In this classification, Sutrayana aims at "emptiness," which is a generalization of the Three Marks, including anatman (non-self). The central method of Sutrayana is renunciation. Renunciation of the self is a major aspect. For Sutrayana, clear sustained perception of anatman (or emptiness more generally) is enlightenment, by definition.

For Buddhist Tantra, experience of emptiness is the "base" or starting point. That's the sense in which "enlightenment is the prerequisite"—but it's enlightenment as understood in Sutrayana. Whereas Sutrayana is the path from "form" (ordinary appearances) to emptiness, Tantra is the path from emptiness to the non-duality of emptiness and form. The aim is to perceive everything as both simultaneously. That non-dual vision is the definition of enlightenment within Tantra. The "duality" referred to here is the duality between emptiness and form, rather than the duality between self and other—which is what is overcome in Sutrayana. The non-dual vision that is the end-point of Tantra, is then the base or starting point for Dzogchen.

(Probably the best thing I've written about this is "Beyond Emptiness: Zen, Tantra, and Dzogchen." It may not be very clear but I hope at least it is entertaining. "Sutra, Tantra, and the Modern Worldview" is less fun but more concrete.)

seeing that the self is an arbitrary construct which you don't need to take too seriously, can enable you to play with it in a tantric fashion

Yes, this is a Vajrayana viewpoint. For Sutrayana, the self is non-existent, or at least "empty"; for Vajrayana, it is empty form. That is, "self" is a label applied to various phenomena, which overall are found to be insubstantial, transient, boundaryless, discontinuous, and ambiguous—and yet which exhibit heft, durability, continence, extension, and specificity. This mild paradox is quite amusing—a starting point for tantric play.

I'll say a bit more about "self" in response to Sarah Constantin's comment on this post.

Probability, knowledge, and meta-probability

Glad you liked the post! Thanks for pointing out the link problem. I've fixed it, for now. It links to a PDF of a file that's found in many places on the internet, but any one of them might be taken down at any time.

Applying reinforcement learning theory to reduce felt temporal distance

A puzzling question is why your brain doesn't get this right automatically. In particular, deciding whether to gather some food before sleeping is an issue mammals have faced in the EEA for millions of years.

Temporal difference learning seems so basic that brains ought to implement it reasonably accurately. Any idea why we might do the wrong thing in this case?

Probability and radical uncertainty

Are there any psychoactive gases or aerosols that drive you mad?

I suppose a psychedelic might push someone over the edge if they were sufficiently psychologically fragile. I don't know of any substances that specifically make people mad, though.

Probability and radical uncertainty

One aspect of what I consider the correct solution is that the only question that needs to be answered is "do I think putting a coin in the box has positive or negative utility", and one can answer that without any guess about what it is actually going to do.

What is your base rate for boxes being able to drive you mad if you put a coin in them?

Can you imagine any mechanism whereby a box would drive you mad if you put a coin in it? (I can't.)

Probability and radical uncertainty

Excellent! This is very much pointing in the direction of what I consider the correct general approach. I hadn't thought of what you suggest specifically, but it's an instance of the general category I had in mind.

Probability and radical uncertainty

Thanks for the encouragement! I have way too many half-completed writing projects, but this does seem an important point.
