Kybernetica.com > AI: Problems with symbolic logic
[Crazy But Able] Different sets of symbols for different problems. But even when everyone is working on the same problem, (acting like or reasoning like human beings, for example) it is hard to come to an agreement on what symbols and rules to use for knowledge representation. Furthermore, the disagreement increases as the complexity of the problem increases.

[Sriks6711-Research] Whatever happened to machines that think? 23 Apr...: The repeated failures of these so-called expert systems - computer programs which, given specialist knowledge described by a human, use logical inference to answer queries - caused widespread disillusionment with symbolic reasoning. The human brain, many argued, obviously worked in a different way.
[Aaron Swartz: The Weblog] Stanford: Another Post You Dont Have to Read: “Hi, I’m Aaron,” I’d say. “What did you think of the talk?” She’d say it’s boring and I’d reply, “Yeah, it’s weird to see someone study the minute details of people who studied minute details,” smiling a little at my meta-y cleverness. And then I suppose my imagination skips some steps, because I imagine kissing her.
[Hyperorg.com] Joho the Blog: Why matter matters: Claus, what part of "body" don't you understand :) When I wrote "body" I actually meant a body, not a simulation of a body. Adding more symbols to a symbolic processor makes it a better representation of brain activity but doesn't make it a brain; adding more symbols makes it a better representation of consciousness but doesn't make it conscious. Hofstadter's piece in "The Mind's I" that postulates "downloading" Einstein's neural states into a book - including the ability to add new inputs and see what the book tells us Einstein would say in response - to me is a pretty convincing proof that symbolic processors are symbolic, not conscious.
[News-opinion.blog-city.com] www.news-opinion.blog-city.com: The following is yesterday's The Progress Report published by the American Progress Action Fund, http://www.americanprogressaction.org , of the Center For American Progress. The report examines both of the above bipartisan actions and the "Under The Radar" section adds short but interesting and important notes on several other topics.
[Themightymjd.com] the mighty mjd - the world's filthiest sports blog: These logos are not going to change anything at all towards the outcome of the game. So I definitely agree with you, this is entertainment, and people over time stop treating sports as entertainment and begin thinking of them as something more and always talk about tradition, etc. The bottom line is that they are still based on entertainment, and to present their product they need money to come in, and as businessmen they have to take every chance to get revenue.
