    I'm not sure if people can look past through the profundity of this statement; but, this is essentially saying another way that the totality of facts is that and only that what an omniscient being can perceive.

    For any person with a self, and with it all the limitations that having a self entails in a world of states of affairs representing facts, then this proposition itself is meaningless. The totality of facts are by essence to such a being, unknowable.

    Hence, whatever cannot be said must be passed over in silence, and let the will do its job, successfully or unsuccessfully as some might argue, in face of such glaring limitations.

    So, get back to work or wallow.

    Mmm, I would say that the world is the totality of perception, whether one knows or does not know the factual quality of something.

    That would require magic, not omniscience. Potential is an object of thought, not perception.

    You hd best fill in the gaps if you want to proceed.

    There is no mention of perception in "The world is the totality of facts". So it must be introduced by some other assumption. What is your hidden assumption?

    This can go about two way's and Wittgenstein choose the rather treacherous/fallacious path of solipsism in the Tractatus and with it private languages if I dare say so. The other path he could have taken is to assert a dichotomy between the self and an object but instead encapsulated both in language by saying that the limits of my language are the limits of my world (as if one could not learn a new word or fact), and the rest of the Tractatus would have fallen apart in my opinion.

    I think the Investigations show's that solipsism was the wrong path to take.

    There are obviously infinite modalities to states of affairs and the world, after all, is not two dimensional.

    The world just is. Facts are something we create from our intersection with the world as part of forming knowledge. Facts are a knowledge construct, even though they are about the world. But they are not the world, as if facts could exist independent of any minds.

    I don't follow that.

    Where does perception fit? Especially since the term does not appear in the Tractates.

    That's just the ambiguity in English of "fact". Witti is very clear in setting out facts as distinct from statements of fact. Marchesk is just backtracking on that distinction.

    Inspired by the recent thread on Zeno's paradox, I shall prove that no "totality of facts" can exist:

    Let T be the set of all facts T={t1, t2, t3, ...}

    Consider, further all subsets of T, which are the elements of the power set of T, P(T) :

    {}
    {t1} {t2} {t3} ...
    {t1, t2} {t1, t3} ...

    To each element of the power set there will correspond a fact, which we construct like this:

    t1 {}
    t1 {t1}
    ...
    t1 {t1, t2, t3, t4}
    t1 {t2, t3, t4, t5}
    ...

    Of course, there is nothing special about t1, a set of facts can be constructed similarly with any tn.

    By constructing our new set of facts, we have a set with as many members as there are in the power set P(T). But, by Cantor's power set theorem, P(T) is always strictly larger than T.

    Thus there are more facts than members of T, therefore no "totality of facts" can exist QED.

    You've only shown there to be no infinite and denumerable totality of facts. There could still be a finite, or a non-denumerable, totality of facts. At any rate, that would not be ruled out on the basis of such a proof.

    Does Cantor's theorem not work for finite sets? I thought there was a well known relation between the cardinalities of a set and its power set?

    As for uncountable sets, I'm pretty sure that Cantor proved that P(T) is always bigger.

    This is clearly not true. A computer is a logical space, which behavior is dictated by logical facts. Ask Turing. And as per the Church-Turing-Deutsch principle, the world is the totality of facts, not things.

    That really depends on the facts of physics. Your proof is a perversion of Zeno's paradox as you state.

    If it were true, then no physical law can be said to be absolute in all instances, which I doubt to be true. Every problem would be a super-task, at least any non-localized problem.

    Nothing to do with Zeno's paradox. It's taking the power set and Cantor's theorem, as I explained.

    And, if supertasks exist, then the CTD-principle is false.

    But a computer is actually a physical device that we invented to do logical things with. You have to have electromagnetism and atoms to make an electronic computer. The whole logical space, boolean algebra, and programming are all abstractions on top of the actual physicality of the machine.

    But if something is uncountable, then by definition, counting it is impossible; and if counting it is impossible, then by definition, it is infinite; and if it is infinite, then by definition it is impossible. Just ask Metaphysician Undercover. :-}
