Why not combine the two approaches? A bicameral mind, of sorts?


I'm sure somebody somewhere is working on it. I've already seen articles teaching LLMs offload math problems onto a separate module, rather than trying to solve them via the murk of neural network.

I suppose you'd architect it as a layer. It wants to say something, and the ontology layer says, "No, that's stupid, say something else". The ontology layer can recognize ontology-like statements and use them to build and evolve the ontology.

It would be even more interesting built into the visual/image models.

I have no idea if that's any kind of real progress, or if it's merely filtering out the dumb stuff. A good service, to be sure, but still not "AGI", whatever the hell that turns out to be.

Unless it turns out to be the missing element that puts it over the top. If I had any idea I wouldn't have been working with Cyc in the first place.


There are absolutely people working on this concept. In fact, the two day long "Neuro-Symbolic AI Summer School 2023"[1] just concluded earlier this week. It was two days of hearing about cutting edge research at the intersection of "neural" approaches (taking a big-tent view where that included most probabilistic approaches) and "symbolic" (eg, "logic based") approaches. And while this approach might not be the contemporary mainstream approach, there were some heavy hitters presenting, including the likes of Leslie Valiant and Yoshua Bengio.

That's right, and left! ;) Fusing the "scruffy" and "neat" approaches has been the idea since the terms were coined by Roger Schank in the 70's and written about in 1982 by Robert Abelson in his Major Address of the Proceedings of the 3rd Annual Conference of the Cognitive Science Society in "Constraint, Construal, and Cognitive Science" (page 1).

His question is: Is it preferable for scruffies to become neater, or for neats to become scruffier? His answer explains why he aspires to be a neater scruffy.

"But I use the example as symptomatic of one kind of approach to the cognitive science fusion problem: you start from a neat, right-wing point of view, but acknowledge some limited role for scruffy, left-wing orientations. The other type of approach is the obvious mirror: you start from the disorderly leftwing side and struggle to be neater about what you are doing. I prefer the latter approach to the former. I will tell you why, and then lay out the beginnings of such an approach."

    Abelson (1981) credits the neat/scruffy distinction to Roger Schank. 
    Abelson says, ``an unnamed but easily guessable colleague of mine 
    ... claims that the major clashes in human affairs are between the
    "neats" and the "scruffies".  The primary concern of the neat is
    that things should be orderly and predictable while the scruffy 
    seeks the rough-and-tumble of life as it comes'' (p. 1).

    Abelson (1981) argues that these two prototypic identities --- neat 
    and scruffy --- ``cause a very serious clash'' in cognitive science 
    and explores ``some areas in which a fusion of identities seems 
    possible'' (p. 1).

CONSTRAINT, CONSTRUAL, AND COGNITIVE SCIENCE

Robert P. Abelson, Yale University

Cognitive science has barely emerged as a discipline -- or an interdiscipline, or whatever it is -- and already it is having an identity crisis.

Within us and among us we have many competing identities. Two particular prototypic identities cause a very serious clash, and I would like to explicate this conflict and then explore some areas in which a fusion of identities seems possible. Consider the two-word name "cognitive science". It represents a hybridization of two different impulses. On the one hand, we want to study human and artificial cognition, the structure of mental representatives, the nature of mind. On the other hand, we want to be scientific, be principled, be exact. These two impulses are not necessarily incompatible, but given free rein they can develop what seems to be a diametric opposition.

The study of the knowledge in a mental system tends toward both naturalism and phenomenology. The mind needs to represent what is out there in the real world, and it needs to manipulate it for particular purposes. But the world is messy, and purposes are manifold. Models of mind, therefore, can become garrulous and intractable as they become more and more realistic. If one's emphasis is on science more than on cognition, however, the canons of hard science dictate a strategy of the isolation of idealized subsystems which can be modeled with elegant productive formalisms. Clarity and precision are highly prized, even at the expense of common sense realism. To caricature this tendency with a phrase from John Tukey (1959), the motto of the narrow hard scientist is, "Be exactly wrong, rather than approximately right".

The one tendency points inside the mind, to see what might be there. The other points outside the mind, to some formal system which can be logically manipulated (Kintsch et al., 1981). Neither camp grants the other a legitimate claim on cognitive science. One side says, "What you're doing may seem to be science, but it's got nothing to do with cognition." The other side says, "What you're doing may seem to be about cognition, but it's got nothing to do with science."

Superficially, it may seem that the trouble arises primarily because of the two-headed name cognitive science. I well remember the discussions of possible names, even though I never liked "cognitive science", the alternatives were worse; abominations like "epistology" or "representonomy".

But in any case, the conflict goes far deeper than the name itself. Indeed, the stylistic division is the same polarization than arises in all fields of science, as well as in art, in politics, in religion, in child rearing -- and in all spheres of human endeavor. Psychologist Silvan Tomkins (1965) characterizes this overriding conflict as that between characterologically left-wing and right-wing world views. The left-wing personality finds the sources of value and truth to lie within individuals, whose reactions to the world define what is important. The right-wing personality asserts that all human behavior is to be understood and judged according to rules or norms which exist independent of human reaction. A similar distinction has been made by an unnamed but easily guessable colleague of mine, who claims that the major clashes in human affairs are between the "neats" and the "scruffies". The primary concern of the neat is that things should be orderly and predictable while the scruffy seeks the rough-and-tumble of life as it comes.

I am exaggerating slightly, but only slightly, in saying that the major disagreements within cognitive science are instantiations of a ubiquitous division between neat right-wing analysis and scruffy left-wing ideation. In truth there are some signs of an attempt to fuse or to compromise these two tendencies. Indeed, one could view the success of cognitive science as primarily dependent not upon the cooperation of linguistics, AI, psychology, etc., but rather, upon the union of clashing world views about the fundamental nature of mentation. Hopefully, we can be open minded and realistic about the important contents of thought at the same time we are principled, even elegant, in our characterizations of the forms of thought.

The fusion task is not easy. It is hard to neaten up a scruffy or scruffy up a neat. It is difficult to formalize aspects of human thought which are variable, disorderly, and seemingly irrational, or to build tightly principled models of realistic language processing in messy natural domains. Writings about cognitive science are beginning to show a recognition of the need for world-view unification, but the signs of strain are clear. Consider the following passage from a recent article by Frank Keil (1981) in Pscyhological Review, giving background for a discussion of his formalistic analysis of the concept of constraint:

"Constraints will be defined...as formal restrictions that limit the class of logically possible knowledge structures that can normally be used in a given cognitive domain." (p. 198).

Now, what is the word "normally" doing in a statement about logical possibility? Does it mean that something which is logically impossible can be used if conditions are not normal? This seems to require a cognitive hyperspace where the impossible is possible.

It is not my intention to disparage an author on the basis of a single statement infelicitously put. I think he was genuinely trying to come to grips with the reality that there is some boundary somewhere to the penetration of his formal constraint analysis into the viscissitudes of human affairs. But I use the example as symptomatic of one kind of approach to the cognitive science fusion problem: you start from a neat, right-wing point of view, but acknowledge some limited role for scruffy, left-wing orientations. The other type of approach is the obvious mirror: you start from the disorderly leftwing side and struggle to be neater about what you are doing. I prefer the latter approach to the former. I will tell you why, and then lay out the beginnings of such an approach.
