Hi everyone, Jon S. sent me this first reference:
*Modus Ponens (CP 2.718):* *Rule. *If *A *is true, *C *is true, *Case. *In a certain case *A *is true; *Result. *.ยท. In that case *C *is true. Compare against: *Syllogism:* *Result. *The surprising fact C is observed. *Rule. *But if A were true, C would be a matter of course. *Case. *Hence, there is reason to suspect A is true. CP 5.189 would only conform as syllogism if surprise/suspect = B. So, is surprise/suspect = B surprising? Is it suspicious? Was your feeling internal/external, etc.? Is surprise/suspect *necessary*? For what is it necessary? That is, what is it *good* for when you could have CP 2.718 and end up with the same thing?
