@Olivier5,
Quote:I agree it is close, but not synonymous. I make a hierarchy between facts and theories;
your idea of a hierarchy of theories is only your own theory, it is not fact. nor is any fact actually a fact, but a mere theory which is well accepted.
Quote:I make a difference between local theories and general, all-encompassing ones. The higher one goes towards generality, the more one must assume all sorts of unproven things. General theories of everything (even of everything as nothing, such as nihilism) assume much much more than simpler, more local theories.
now, even if i accept your claim of hierarchy of theories, the idea that local ones are always more plausible than general ones is also preposterous. just because a local theory only requires smaller assumptions does not make it any more likely to be true.
Quote:Hence it is perfectly coherent logically to say: we can't access the ultimate truth.
furthermore, your idea that 'there is no ultimate truth' is itself the MOST generalized possible theory. you think that 'we can't access the ultimate truth' is a nice, local theory? no, it is the most generalized possible thing you could ever say. you are assuming that humanity as a whole is incapable of finding such a thing as 'ultimate truth', also assuming you know that no such thing exists. all because you yourself have the personal opinion that you are unable to access any such truth.
also, if you say 'we can't access the ultimate truth', that itself IS an ultimate truth, because it is an absolute fact about the inability of all humans to access such a thing. that is extremely generalized and ultimate.
Quote:That in itself is not an ultimate truth, in the sense of "a true theory of everything".
the idea that we cannot access the ultimate truth IS by definition then your 'true theory of everything'. it extends to all humanity and becomes the way you define 'everything'.
