I envision the "causal" links as being at statements about the physical layer. And everything covered with "amount of belief" . The model would also need to include mechanisms believed to be in operation. (E.g., "fire is caused by the phologiston escaping from the wood"). And mechanisms would need to be in place for correcting and updating the model. Etc.
Conversational type logic statements, then, would be seen as being for the purpose of directing attention to specific portions of this model. And "deductions" from these informal logic statements would need to be checked and verified against the model. Sensory data would be more significant, but there's considerable evidence that even sensory data has a hard time in overruling a strong model belief. ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=108809214-a0d121 Powered by Listbox: http://www.listbox.com
