Russell's paradox is not a paradox in modern axiomatic set theory - the "set of all sets" is not a set.

That was fun, right up until this part:

*It may well be that in math there are multiple truths, some of which are contradictory (an instance of this can be found in the difference between euclidean and non-euclidean geometry (or any other undecidable proposition)).*

I am disappointed in both the essay and the commenting.

Here's why: When he gets to Gödel, he moves from a bunch of fluffy masturbatory self-referentialism into the realm of explaining exactly why it should be interesting. But he fails by not supporting Gödel's argument that in any system it's possible to create a statement that is self-referentially unprovable. I'm not saying that Gödel didn't prove that, just that by going from his argument in mathematical terms to a rather weak analogy about electric guitars, he fails to present a compelling case.

And I know, I know, he starts out with the ironic assertion of the essay's fallibility. Tres cheeky.

But he falls into the central trap of an over-emphasis of self-referentialism: it's often a clever way of being absolutely meaningless.

The author obviously has done his research and has interesting things to say, but he fails by succumbing to the tone of frivolity at the expense of content.

(Metamagical Themas, one of the two Hoffsteader books he cites, is quite good even if it's a bit wanky too. I've often thought about reading the Gödel, Escher, Bach one but never got around to it).

And the comments? They look like the sort of thing you'd see on Monkeyfilter.

gleuschk, I think Marilyn vos Savant's argument was based on the fact that Fermat certainly did not prove his last theorem using non-euclidian geometery, and therefore there is still the mystery of how Fermat would have proved his last theorem.

Not that I'm a mathematician...

And personally I believe in multiple "truths," because math is a human construct.

And as another note to teferi, Set S is still a set by my definition: something that contains things.

No, unless you're going to digress into wordplay. There's a question about that? Is "red" red? Where's the paradox?

Actually, it was in German, and perhaps you feel that it might as well be in German anyway.

That would be funnier if the original statement didn't contain things made purposely difficult to understand by removal from context.

And the essay would have been better had it not been so cutesy-poo, especially in the opening quotes.

Speaking as a mathematician, I would like to point out a few problems with this essay. Not in order to destroy anybody's fun, but just to try to clear up a few misconceptions this essay might create.

*The Principia Mathematica, in its zeal to eliminate paradox, does away with several useful concepts which are important parts of human reasoning. With no recourse to references of self, we are left with no way of expressing anything about ourselves.*

The problem here is that Principia Mathematica wasn't written to express anything about ourselves or to model human reasoning; the point of Russel and Whitehead's work was to put mathematics on a rigorous, logical basis. One does not write poetry or essays in formal mathematical language. If you want to express something about yourself, I recommend English, or whatever other natural language you prefer.

*However, the fact that we cannot create a formal system which can capture all of mathematical truth casts serious doubt on the objectiveness of such truth. It may well be that in math there are multiple truths, some of which are contradictory (an instance of this can be found in the difference between euclidean and non-euclidean geometry*

Godel's theorem says that in any formal axiomatic system which is sufficiently complex, there are statements in the system which can be neither proved nor disproved within the system. This is known as the Incompleteness Theorem.

This is not the same as saying that there are statements which are true and false at the same time, i.e. paradoxes.

There is a second part to the Incompleteness Theorem, which says that the consistency of such a system cannot be proved within the system. That is, one cannot rule out the existence of paradoxes. But nobody has found one yet. The example of euclidean and non-euclidean geometry is misleading, because these are two formal systems that use a different set of axioms; that is, the systems are different. Euclidean geometry is the geometry of a flat plane, whereas non-euclidean geometry is the geometry of curved surfaces such as spheres or saddle-shaped surfaces.

Some statements of geometry are true in one system but not the other. For instance, the angles of a triangle in a flat plane always add to 180 degrees, but this is not true for triangles on the surface of a sphere. This is not a paradox, because we're talking about different kinds of triangles. If you could find a triangle in a flat plane whose angles added up to 179 degrees, that would be a paradox.

Sorry for the length of this post, but Godel's theorems get tossed around a lot without people really understanding what they mean, so I had to try to set things straight.

But mathematics inevitably influences other fields as well, including Semantics. For example, Quantum Mechanics has been wrongly canonized by mystics. Humans will continue, forever I suspect, to mix up fields that shouldn't be mixed, but that's what keeps things interesting.

I bet Fermat's "truly remarkable proof" was incorrect in some minor (or major) way. His legacy has been better served by leaving it a mystery, since we would not be nearly so interested in his mistakes, nor would we have any reason to believe that it was possible to prove it correctly. I wonder if he did this deliberately.
