Perhaps this is acceptable; if not, then the definition needs revision, since obviously from one perspective the application to computers is (although tongue firmly planted in cheek) not so far-fetched. I'm looking forward to any sound and complete defintions of: KNOWLEDGE, BELIEF, INTUITION, INDUCTION, IMAGINATION, INTELLIGENCE. believe me. ---------------------------------------------------------------------- Let me take a tangent that may shed some light on the subject: Is it wrong to call a teddy bear a "bear" or Sherlock Holmes a "person"? A real bear is an altogether more serious and thoroughgoing thing: its "bearness" is generative, that of the teddy ascribed. The bearness of a teddy bear is a *metaphorical shadow* of that of the real bear. Now let's look at a pc running ELIZA. The "statementness" of its character strings, the "knowledgeness" of its stored keywords, are metaphorical shadows of the real things. Now I claim that the relation of the pc to the human mind is like that of a kitten to a tiger or a dollhouse to a bungalow. They are quite similar in many respects, form and function, but so drastically different in scale as to be qualitatively separate things. All the ancillary details may be the same, but the defining characteristic is missing: the kitten is not deadly, the dollhouse is not shelter, the pc is not intelligent. Moravec estimates 10 teraops/10 terawords to be human-equivalent computational power. I would be quite comfortable with one teraop/ one terabyte: the scale of a pc to such a machine is fairly precisely that of a bacterium to a human body. I am not even sure we have to talk about the things the pc does as requiring any amplification but the quantitative: it it did a million template matches for every one it does, held a million facts for every one it holds, selected its statements from a set a million times the size; will this be understanding, knowledge, judgement? Maybe so. But until then, there is a qualitative difference hiding in the quantitative one. --JoSH
