Re: Metaphysics of the coming age (none / 0)
Yes, and it failed on "this statement is false". That's the basic point of Gödel's proof. I don't know how they expected to attribute a truth value to that statement, those formal logicians ; but that you can't attribute a truth value to it sounds even a bit reconforting... Logic doesn't get out of the realm of human experience about truth values.

Re: Metaphysics of the coming age (none / 0)
Many antinomies (paradoxes,) such as that one - a variation on wossname's 'All Cretans are liars ...' - have an oscillating first order Truth Value with the TV changing depending on the step: On True Then False Then True & etc XOR On False Then True Then False & etc.  Since they are infinitely oscillating there is no resolution possible.  

By moving to the Second Order, on the other hand, the True/False OR False/True oscillation is, sometimes, capable of resolution.

But that, very often, takes you outside the original axiomatic system.

It ALSO failed on (none / 1)
"Arithmetic is consistent"

That was the sailing-over-the-edge moment.  

Now it may be that arithmetic really is consistent, but that is another truth function that is "uncomputable."
