There is a substantial amount of literature that claims that *humans* can't
generate new ideas de novo either -- and that they can only build up "new"
ideas from existing pieces.

The epicycles that the sun performs as it moves around the Earth are also very
numerous and complex -- until you decide that maybe you should view it as the
Earth moving around the sun instead. Read some Pinker -- the rules of language
tell us *a lot* about the tough-to-discern foundations of human cognition.

Subject: Re: [agi] would anyone want to use a commonsense KB?
My latest thinking tends to agree with Matt that language and common sense
are best learnt together. (Learning langauge "before" common sense is
impossible / senseless).
I think Ben's text mining approach has one big flaw: it can only reason
about existing knowledge, but cannot generate new ideas using words / concepts.
I want to stress that AGI needs to be able to think at the WORD/CONCEPT level.
In order to do this, we need some rules that *rewrite* sentences made up of
words, such that the AGI can reason from one sentence to another. Such rewrite
rules are very numerous and can be very complex -- for example rules for
auxillary words and prepositions, etc. I'm not even sure that such rules can
be expressed in FOL easily -- let alone learn them!
The embodiment approach provides an environment for learning qualitative
physics, but it's still different from the common sense domain where knowledge
is often verbally expressed. In fact, it's not the environment that matters,
it's the knowledge representation (whether it's expressive enough) and the
learning algorithm (how sophisticated it is).
