It's been on my mind for a while and I'de like others opinion. Like in my signature, can anything be absolutely true? Perceivable truth could be due to our naïve sense of perception. But since certain things have variability and could turn out to be completely different than what was originally thought (like Psychology). Then such things could turn out untrue. Doesn't, or shouldn't this principle go for everything else?
The term, "absolute truth" has been used in a lot of different ways, so that it is not immediately clear what you are asking about. From what you say, it looks as if you mean by saying that a belief or maybe a statement, is an "absolute truth" only if it could
not be false, and not merely is not false, and so that no one could
be mistaken when that person believed it was true. . So what you really seem to be asking is whether there is anything we can believe that it is impossible for us to be mistaken about. In other words, whether we can be completely (absolutely) certain about anything. So, your questions seems to me to be more about certainty than truth, for we could all have a true belief about which we are, nevertheless, certain that it is
true. I wonder, though, whether I am on the right track, and whether I am right about the question you are asking. [ In philosophy (unlike in the sciences) I think it is at least important to consider the question, and what it means, before trying to answer it]. So before even trying to answer your question, I'd like to know whether what I think is your question really is your question. There is no point is trying to give an answer to a question you did not ask. Isn't that true?
