In my experience those are the only conclusions that have ever been drawn. I have never yet heard of someone drawing correct conclusions from correct premises. I mean this seriously. This, I think is Dr. Minsky's point this morning. What this leads to is that the notion of deductive logic being something sitting there sacred which you can borrow for particularly sacred uses and producing inviolable results is a lot of nonsense.
Deductive logic is inferrred as much as anything else.
Most women have never inferred it, but they get along pretty well, marrying happy husbands, raising happy children, without ever using deductive logic at all. My feeling is that my criticism of Dr. McCarthy is the other way. He assumes deductive logic, whereas in fact that is something to be concocted. Dr. McCarthy would be the first to admit that his proramme is not now working, so it has to be changed. That has nothing to do with logic.
