> Gödel's theorem is rubbished
I am curious, could you elaborate a bit on this? If the Tractatus is about the inability to say something about a system from within the system, then isn't this basically what Gödel's theorem is about?
- galaxyLogic 4y agoI'm curious too. Can we right-away accept the proposition that "A Sentence can refer to itself"? If a sentence refers to 'this sentence', what does it in fact precisely refer to? And what is the "it" that does the referring? Maybe, a "sentence" can not refer to anything. It is the person uttering the sentence that does the referring. But then of course when he or she says "this sentence" they would really mean, me, this person.
- skyechurch 4y agoWith the warning that I am not an expert, see my answer below. While there is obviously thematic overlap between the Tractatus and Gödel, Wittgenstein himself viewed Gödel's work as fundamentally nonsensical. Now why the "nonsense" of the Tractatus is ok, while the "nonsense" of Gödel is not, is admittedly not clear, and we are under no obligation to respect it, but that would be (early) Wittgenstein's opinion.
