If you mean that someone can claim truth from illogic, sure, it has been done. And it even is possible that the conclusion could be proven right from some other argument. But it would never amount to saying that the truth was technically established from illogic.

And when would you label a body of logical rules as illogic? Is quantum logic a logic that you would label 'illogic' because it is not compatible with propositional logic?

He first formulated his ideas (based on work of Reichenbach and Quine) in the sixties. Some critics complained however that he had left out the many world interpretation of QM. In 2005 he gave an update which expanded on the Everett Many World interpretation of QM.

I bet he'll say 'yes' . i keep straying from my initial purpose of this whole argument: is there any reason to believe an illogical universe could exist? does the term 'illogical universe' have any meaning at all? if there is no reason to believe an illogical universe may exist and no meaning in the term 'illogical universe', saying a universe is logical becomes redundant.I don't know if such an agent is needed to allow logic (any kind of logic that is) in these universes, but be careful, it certainly is an argument that theists are making and build on to construct gods.
If for you, as you seem to suggest in several places, illogic is everything that does not obey propositional logic, than in that vocabulary I'm forced to conclude that Putnam argues for the existence of illogical universes and that our universe is one of them. On the other hand, if you ask Putnam he would not use the term illogic for alternative logical frameworks such as quantum logic. So what's your choice of words?
