X-Message-Number: 11760 From: Date: Sat, 15 May 1999 21:19:03 EDT Subject: Norton, Crevier, zombies & philosophers Brook Norton today (May 15 Cryonet) gave us a clever approach to the "zombie" question with the example of an oscillating steel rod and its simulation by a computer. This was in response to various posts by Daniel Crevier intended to show that a simulation is equivalent to the original. I will not reproduce the posts here. I don't think his example actually proves anything, because the disagreement between the two camps is one of premises, not of conclusions from an agreed premise. Mr. Crevier's premise, essentially, is that if it looks like a duck it's a duck; and underlying this is the deeper premise that isomorphism is everything. Mr. Norton's premise is that if it is physically different then it isn't the same thing, or a description of a thing is not the thing. What we are really talking about is appropriate criteria of survival, and hanging out there also is the quantitative postulate, that survival is a matter of degree--and carried to its logical conclusion, this implies that if anything about you survives, then you have partly survived, which brings us back to the quaint notion that you can "live on" in your works or in your children etc., in contrast to the criterion of Woody Allen, who says "I want to live on in my apartment." By the way, out of curiosity: Is there anyone out there who, after forming an opinion on this or any "philosophical" issue, has ever changed his mind because of a persuasive argument? As far as I recall, not a single one of the published philosophers has ever changed his opinion, even after decades of argument.
