I'd rather get ride of the notion of "attractor" altogether. Though it may be useful for perception, in high-level cognition I don't see anything like it. Of course, some beliefs are more stable than others, but are they states to which all processes converge? > Hmmm....

What I mean is not that NARS, as a reasoning system, can be (partially or completely) implemented by a network, but that NARS can be seen as a network --- though different from conventional NN. I think NN is much better than traditional AI in its philosophy --- I like parallel processing, distributed representation (to a certain extent), incremental learning, competing results, and so on. However, ironically, the techniques of NN is less flexible than symbolic AI. I don't like NN when it uses fixed network topology, has no semantics (and even claims it to be an advantage), takes the goal of learning as converging to a function (mapping input to output), does global updating, uses "activation" for both logical and control purposes, and so on. My way to combine the two paradigms is not to build a hybrid system that is part symbolic and part connectionist, but to build a unified system which is similar to symbolic AI in certain aspects, and similar to NN in some other aspects.
