Okay....
Choose a proposition, any proposition. (Yes, I am trying to keep a "light" tone here.) Call the proposition P.
Proposition M: I know, without the possibility of error, that P.
Now, can M be true if P is not necessarily true?
Of course, my claim that M is true might be impossible to justify, but if it is justifiable, does it not entail P?
Two other questions:
1. If P is "Obama will win a second term," could M possibly be true. (I don't mean to imply he can't win; I wonder about the philosophical implications of puportedly infallible predictions.)
2. Would P have to be true, a priori? (E.g., 2 + 2 = 4)
