Of course. E.g. modal logics allow different types of "therefore", say ⊨_a and ⊨_b. Then it might be true that "Let X be Y ⊨_a X is Y" but false that "Let X be Y ⊨_b X is Y". Similarly, I can imagine a logic where "be" and "is" mean different things. > On 09/21/2017 05:00 PM, gⅼеɳ ☣ wrote: > Yes, of course. E.g.

The whole point of my response was that you are over-simplifying both belief and action in order to tell a "just so story" and force the story to fit your philosophy. It seems reasonable to me that if actions are decomposable, then so would be beliefs because there's no difference between beliefs and actions. But you are saying something different. Somehow, to you, beliefs are different from actions. > */[NST==>I think a body can enact conflicting beliefs at the same time, but > that is because I am comfortable with the idea that that the same body can > simultaneously act on two different belief systems.

If the same body can do 2 conflicting things, why can't the same belief system be composed of 2 conflicting things? This is why I raised the idea of paraconsistent, defeasible, and higher order logics. Specifically _those_ types. Why do you treat belief systems as fundamentally different from physical systems? -- ␦glen? ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com FRIAM-COMIC http://friam-comic.blogspot.com/ by Dr. Strangelove
