Supermarket-Example/Perry: (Sugar trail, "Mess in the supermarket" - someone notes that it was he himself who has made a mess) - opinion context: the reader, now - judgement context: the man at the supermarket. - Problem: the mere fact that I considered the proposition that I make a mess at any time for true, does not explain why I stopped. - The reader feels the same way and does not stop the cart. - N.B.: for me opinion context and judgement context coincide - but it is not a solution, because self-identification cannot do without a sentence with "I".
Wanderer/supermarket/Perry: Solution: distinction opinion state/opinion: E.g. opinion state: "The event will begin" - "it begins now" - "it has begun" - opinion: all the time I believe that it starts at 12:00 - opinion state: for all the same (with index word) - opinion: different: not the same relation to the same subject. - VsTradition: if it were different, we would all have to expect a common believed proposition if all are in the same opinion state. - Normally one will adjust his opinion states when one goes from one context to the other to preserve his opinions.
