For something to be objectively true it need not transcend the universe. <br /><br />2. Aside from notation of course, wouldn't mathematical truths be absolute and true in every possible world?<br /><br />3. When I say for example "X is absolutely true", I mean that no one's opinion can falsify that truth, and that its truth is dependent on a logical and/or physical reality that everyone could in principle, independently verify and reach the same conclusion, regardless if there is a given external objective reality as an axiom.

I don't see how "truth" can exist independent of a theory of truth (I also don't know if what I'm saying makes sense if one studies theories of truth extensively, since I have not).Rianhttps://www.blogger.com/profile/08021810579773953296noreply@blogger.comtag:blogger.com,1999:blog-7110460687773644977.post-13463331423989652842013-05-30T18:45:42.352-04:002013-05-30T18:45:42.352-04:00It is true that absolute and objective are not nec...It is true that absolute and objective are not necessarily the same thing.

From my perspective, the phrase "absolute truth" doesn't make sense without additional context.<br />If you're simply using "absolute" as a synonym for "objective", that's all well and good, but what does it mean to say something is objectively true?<br />It seems to me that in explaining what you mean, you end up including a lot of context (within the axioms of classical logic, within external empirical reality, etc). To simply state that "absolute truth exists" without including this context seems to me to be nonsensical.Rianhttps://www.blogger.com/profile/08021810579773953296noreply@blogger.comtag:blogger.com,1999:blog-7110460687773644977.post-21572850970010195112013-05-30T17:04:21.717-04:002013-05-30T17:04:21.717-04:00Looking at this from a purely logical point of vie...Looking at this from a purely logical point of view, if you say there is no such thing as an absolute truth, wouldn't that be an absolute truth, if it were true?The Thinkerhttps://www.blogger.com/profile/14303015383137218932noreply@blogger.comtag:blogger.com,1999:blog-7110460687773644977.post-4971191511391214562013-05-30T16:47:25.700-04:002013-05-30T16:47:25.700-04:00Maybe we don't agree :-)
