Kurt Godel: The World's Most Incredible Mind.
"Either mathematics is too big for the human mind or the human mind is more than a machine" ~ Godel
Kurt Godel (1931) proved two important things about any axiomatic system rich enough to include all of number theory.
1) You'll never be able to prove every true result..... you'll never be able to prove every result that is true in your system.
2) Godel also proved that one of the results that you can never prove is the result that says that the system is consistent. More precisely: You cannot prove the consistency of any mathematical system rich enough to include the known theory of numbers.
Hence, any consistent mathematical system that is rich enough to include number theory is inherently incomplete.
Second, one of the propositions whose truth or falsity cannot be proved within the system is precisely the proposition that states that the system is consistent. "
What Godel's proof means, then, is that we can't prove that arithmetic-let alone any more-complicated system-is consistent.
For 2000 years, mathematics has been the model-the subject-that convinces us that certainty is possible. Yet Now there's no certainty anywhere-not even in mathematics.

Goedel's Ontological Proof.
For those interested in a discussion of Goedel's reasoning for God, then I suggest starting with this heavily annotated work, which I recently stumbled upon.
www.scribd.com/doc/95364925/Goedel-s-God-Proof-Annotated-Version
"It's not that God is subject to the Freedom Proof or the Doubt Proof.
According to Gödel, He's not. But we have to be, or else we are not free. So
our truth game with God turns into something like Feynman had described.
Feynman's Gods, every time physicists think they have the rules of the game
figured out, throw in a new wrinkle. They let people like Feynman make
progress, but if the Feynmans of the world learn too much, physics will stop
being the joy and challenge that it is. The Gods don't let that happen.
Gödel's God has to be very careful about how he lets our universe unfold.
If the world becomes totally controllable and comprehensible, we'll be God.
God does not object to that. In fact, according to Gödel, that is our destiny.
But it is also the end of us as free human beings. And human freedom is an
essential part of the beauty of God's universe."

What Godel shows with incompleteness theorem, is that the human mind has a capacity for intuition and creativity, which ultimately lay at the foundations of reasoning. This is in direct opposition to logicistic attitudes, which suggest that the formal axiomization of mathematics could lead to all truths. Godel understood that truth (including logic) relies on the foundations of axioms, not all of which have been discovered, and our infinite.

Agreed! Blind faith in religion has simply been replaced by blind faith in Science. But i guess the flip side is that the educational system mostly stifles creativity and curiosity, and children are "made" to study rather than them "wanting" to. This state of affairs will never lead them to ask questions which are on the edge, which question the results, which stretch the science beyond the banal examples which are given in the classroom and which lead to incremental learning...

There's some confusion in the comments about implications of the theorem. I've studied Gödel quite a bit. An analogous finding was Turing's "undecidability", which proved that every program has a problem which it fundamentally cannot solve even if you gave it an infinite amount of time. The two are analogous to everything: if we build some kind of thinking process out of rules, that system will ALWAYS be flawed. I'm attempting to write a book on expanding the logical implications and some more commonsense analogies.

If the public were to become uncertain, then they would become less vested, and perhaps turn to alternatives, or turn to themselves, or perhaps turn to direct relationship with the spiritual. All of these trajectories disintermediate the current power structure. Hence, Goedel's findings are extremely dangerous to the status quo.

I am amazed that people are still talking about the mind/machine issue. The resolution is simple. An analogy goes like this: Ask this question: "In general, is it possible to trisect an angle?" The knee-jerk mathematical response is: "Of course not! Everybody knows that!" But the better response is: "Of course you can! Just not with a compass and straightedge." The mind/machine issue similarly hinges on the technical definition of the word "algorithm": a finite set of instructions that is guaranteed to produce a correct result in a finite time. Human minds are not an algorithm. Neither do they need to be anything more than a computer to do what they do. A human mind is a gigantic (but finite) non-terminating (except by death) Monte Carlo process, some parts of which run in a deductive (mathematical) mode. It has been possible to build something mind-like for decades now. The trick is to recognize what a mind is by recognizing what it accomplishes, and then noting how it does it. It's like evolution: once you see the trick, there is nothing hard about it. What turns out to be hard is encompassing all of the consequences of the little trick.

+Steven Abell Well, it is possible to trisect an angle using origami. There are some problems that are impossible by ANY finite construction, like, for instance, squaring the circle. So this means the mind/machine issue is solved? Um, ok. So how did you reach the conclusion that the mind is a giant Monte Carlo process? What exactly do you mean by a Monte Carlo process? The Monte Carlo process refers to the generation of random numbers in a computer to solve some problem. So, if the mind is a Monte Carlo simulation, does that mean the human mind is a computer generating random numbers or... I'm not clear what your point is.

@Pooja Deshpande Set theory is not inconsistent. In order for a system to be inconsistent, it must be the case that both a formula of the system and that very formula's negation can be proven within the system (I.E. you can prove some formula P and you can also prove NOT P). Set theory is a consistent system. It is impossible to prove both a formula of set theory and that very formula's negation within set theory. Godel's incompleteness theorem does not demonstrate that set theory is inconsistent (this cannot be demonstrated, because set theory is consistent). Godel proved that set theory is incomplete. A system is incomplete if there is some formula of the system which is true, but cannot be proven within the system. Godel's theorem demonstrates that there is at least one formula of set theory which is true, but cannot be proven according to the deductive rules of set theory (it follows that there are actually infinitely many formulae of set theory which cannot be proven). Now, to answer your question: you asked why set theory is still taught in schools even though it is inconsistent. If set theory were inconsistent, it would hardly make sense to teach it at all. For example, if basic arithmetic were inconsistent (it is, in fact, not), then we would be able to prove both that 1 + 1 = 2 and that 1 + 1 =/= 2. In an inconsistent system, you can prove anything, no matter how crazy-sounding! So teaching it would be a breeze because every formula you demonstrate can be proven. The only downside would be that you could come in the next day and teach the exact opposite of what you had taught the previous day without breaking the rules of the system. That is why it is important to teach consistent systems. However, there is a much more interesting question of why it is that we still teach incomplete systems (like set theory). I find this question much more open to discussion, as there are many different arguments in favor of teaching incomplete systems. One point to be made is that systems which are both complete and consistent are often not considered "interesting" as fields of study. For example, first order predicate logic is a system which is both consistent and complete, but the complexity of provable statements within first order logic comes nowhere near the complexity of some of the results provable within set theory. Another argument one could make in favor of teaching incomplete systems is to appeal to the results provable within the system themselves. Much of our discoveries in mathematics rest on set theory as a foundation for demonstrating our results, and giving up set theory might also mean giving up on those discoveries. Again, my answer to this second question is much more speculative than the first, but I hope I was able to clear up the confusion about the consistency of set theory and explain why we still teach set theory in schools even after the discovery of Godel's incompleteness theorem.

It's only inconsistent if you're too loose with your definition of "set". That problem was eventually solved. The concept of cardinality (or "size"- two sets are the same size if their elements can be put in 1-1 correspondence) is, for finite sets, the underlying concept that the "counting numbers" 1,2,3... are based on, so sets are indispensable in math.

I'm not sure what you mean. Completeness has to do more with formulas in a system which are also theorems in that system. So a system is considered incomplete if there is a formula in a system that cannot be proven. I haven't taken enough number theory, though I would imagine it wouldn't be trivial to attempt to prove this rigorously enough for mathematicians. If there is something I'm missing, I would like to know.

You're account of gödels incompletness theorems is roughly correct, depending on what you mean with "related to arithmetic" and "provable". The english wikipedia article on the theorem is probably an ok read. It is wrong though, to say that the "second incompleteness theorem is special case of the first one". I see no connection between them. It is however very hard to explain that, as the whole conext of argument is extremely technical and it feels impossible to give an appropiate account without laying out the formalisms. A few things I can say though: - beware that the 1. and 2 . theorem do not exactly speak about the same sets of axiom systems. - the first incompletness theorem does not exactly give you "statements that are true but not provable", instead it gives you statements whose truth cannot be determined, within an appropiate axiomatic system. it is not clear wether these statements are true or not in an intuitive sense, for all I know, it could be that alle the statements whose truth cannot be determined are false. (the concept of truth has to be treated very carefully here, as the only way we can communicate truth are axiomatic systems, so its weird to say that something is true even though all the seemingly good axiomatic systems do not tell us it is true) - the second gives you statement where one cannot infer that it is true. that is different from saying you cannot infer its truth value, because "one cannot infer that it is true" still entails the possibility of you infering that the statement is wrong. "you cannot infer its truth value" does not leave that possibility open. the first theorem gives you such statements. - the wikipedia article says that the proof of the second theorem can be obtained by formalizing the proof of the first one. I don't know about that. We didn't do it that way in my class, never read about that either, not even in philosophy books. seems like a cumbersome way of doing things.

Consistency allows some things to be true and others false. Inconsistency makes everything and its opposite true. You really have to expect the answer to the consistency question to be “yes”. In an inconsistent world, you can answer the Consistency Question and any other question “yes”. In a consistent world, “yes” is the obvious answer to the Consistency Question. So that’s two choices. One is “yes” and the other is “yes”. Gödel"s Proof showed the answer to the Consistency Question was “no”.

The importance of the proof is not that when you measure the length of a building's shadow and its angle with the ground that you should distrust the height you calculate.

I am not advocating a sort of Platonic mathematical ideality, but I still believe that mathematics is something objective and independent of the human mind. I am not altogether sure I understand my current conception of what mathematics -is-.

4:22 "Doctoral dissertation: completeness of first order logic" The set theory everyone is talking about here is *equivalent* to fist order logic. Which Godel proved was COMPLETE. Not incomplete, not inconsistent; Consistent and Complete.

I am a man. Self-referential, but not "stupid and fake". The problem with those self-referential paradoxes is that the object of those sentences are not complete enough to ascribe "truth" or "falseness" to. "This sentence" is neither true nor false, by itself. It does not assert or deny anything. Same thing for "time", or "space", or "apple", or "man", or anything like that.

The labyrinth finally destroyed Goedel as it did Newton, Weierstrass, Cantor, Frege, Ramanujan, von Neumann et al. They used bad infinities & not the transfinite fractions of Non-Cantorian set theory. I painted a large triptych called The Madness of Mathematics.

No we are NOT, and Godel helps to show this. John von Neumann took Godel Numbering and used it to help create binary numbering systems, which can be "gamed" to create a Complete Formal System where there is none, via a computer controlled virtual "reality".

"For something to be either true of false it cannot be self referential, it must refer to something outside itself." Really? "This sentence has five words" is self-referential and true.

Wrong. It refers to, splinters off into several ideas- sentences, words, numbers, etc. If you think that is the same as "The apple is false." You just don't get it, sorry. Very different. Thank you very much for proving my point. Next? QED.

It was not Russell, but Cantor that showed that *naive* set theory was inconsistent. The axiomatic set theory that mathematics is based on is *consistent*

Love this godel stuff....how can we find extra solar aliens or planets unless we ourselves possess the means of measurement,or are ''alien'' ourselves...relativity for the exo planetary explorers...you cannot be or see what you are not, or is outtside of the structure that is a limited realm of self or being, or body, or universe.

@QuantumBunk: One could say paradoxes are "stupid & fake" if they are KNOWN and ACKNOWLEDGED. One of the biggest problems with mathemetatics, science and computer technology is that they are being sold to the public as techniques and systems that are infallable. The general population does not understand the weaknesses and faults inherent in these system, and therefore they place them on a pedastal that is undeserved.

Please do not forget, that people like Einsten and Gödel lived in times, when being an atheist was not an option. If anyone would have taken the position of an atheist, he wouldn't have the chance to study or the chance for a job. At this time, churches have been overcrowded on sundays. If you're not there taking part in praying silly crap, you'd have a very good excuse or become an unadapted outlaw. Like in the bible belt today.
