- Leaning:
- I agree with almost everything you say about the environment (and so do Chapman
- and Agre, who say that the natural world is much more dangerous than
- the artificial one we make for ourselves with culture). The target of the
- `leaning on the environment' slogan are the `planning weenies', who really
- seem(ed?) to think that a competent Agent ought to calculate the results
- of its actions from first principles. As to `how many' regularities
- there are in nature, I doubt that this is a question that can be profitably
- argued about. At a very minimum, PCT depends on there being consistent
- correlations between the direction of gross effort and the direction of
- change of net result, & a continuous function relating the magnitudes of
- these two quantities. One is thus `leaning' on everything that causes
- these correlations to exist, without having to know anything about these
- underlying causes or do any computations involving them (like a conventional
- Planning Agent would have to, if what I read about them in Beer, Chapman,
- and Agre is true (I haven't really gotten around to Brooks yet)).
-
- Beerbugs:
- I'm still confused. I have on the page before me a diagram of a circuit that
- ought to work, and is supposedly based on the actual wiring of a real critter,
- and which I believe I described accurately. Even if Aplysia doesn't actually
- work that way, I don't see any reason why some other critter couldn't, &
- I don't (yet) see how to apply your description to the actual circuit.
-
- But maybe the light will dawn....
