Hmm... "To consider" does not have presupposition of truth. I could say: "Yahoo press releases are considered defacto truth, but they are not." But I can't say: "Yahoo press releases are known defacto truth, but they are not." So I would keep {jinvi} for "consider". As for {krici} vs {jinvi} for "I thought", either works for me. I used {krici} because I was already using {jinvi} in the same sentence, and besides there did not appear to be much justification for the belief. >Let us say that the particular news item indeed DOES convey truth (as >widely recognized). But we won't disagree in this case. What do you mean by truth "as widely recognized"? Do you mean fatci? > For some people it is truth because they got it from >Yahoo press releases.

Thus A djuno F fo la ia'us. >and B djuno F fo le drata, but B na djuno F fo la ia'us. because B does not >accept the epsitemological source as valid. That's fine. I agree that people can come to know things from different sources. As long as it is a truth (as widely recognized) then some people may know it from having read it in the press release, others may know it from someone else having told them, others might know it from different sources. As long as we are all in agreement that there is a widely recognized truth to be known. Our difference of opinion comes when there is no such widely recognized truth. Let's say Yahoo by mistake releases some report F that is obviously false to everyone as widely recognized. Would you still claim that A djuno F fo la ia'us? You certainly would not say in English that A knows F from having heard it from Yahoo. >Clearly here, to A, F jetnu la ia'us is a true proposition, while to B it is >a false proposition. That's what strikes me as odd. You're saying that "F jetnu la ia'us" has no widely recognized truth value. A will claim it is true, B will say no it isn't, and there's no way they can reach an agreement? Is jetnu just a matter of preference? This is not what normally happens with other predicates. Good thing we have fatci then. For example, I might claim: (1) i ta blanu That is blue. (2) i di'u fatci That's a fact. Now, how do we know whether (1) is true or not? Well, in most cases people agree what things count as blue, so if {ta} is a more or less central example of blueness there won't be disagreement. And by the same metaphysics as (1) is widely recognized as true, (2) will be widely recognized as true as well. The differences of opinion will be the same ones that occur about (1). Or are you saying that we could have (1) being true and (2) being false by the same metaphysics? On the other hand, using jetnu would complicate matters a bit more. We could say: (3) i di'u jetnu which would be equivalent to the simpler claim (2). Saying just: (4) i di'u jetnu will also work, because the understood metaphysics would be the same as that implicit in (1) and (2), wouldn't it? But there will be more room left for doubt as to what is meant. co'o mi'e xorxes
