Gödel Theorems of Incompleteness
Syed Fawad Bokhari
Particularly on the “Fermaish” of Idrees Azad sb, which was made on the first post of Khawar Asad, i.e. to discuss Gödel Theorems in a separate post. Some part of the this post contains the comments that I made during different discussions on “Mukalama” group.
Gödel theorems of incompleteness:
———————————————-
———————————————-
The theorems (Theorem I and II) are a hallmark in mathematical logic and in the philosophy of mathematics.
Gödel’s first incompleteness theorem shows that any consistent effective formal system that includes enough of the theory is incomplete: the true mathemtical statements expressible in its (mathematical) language that are unprovable within the system.
Simply speaking: Any effectively generated theory capable of expressing elementary arithmetic cannot be both consistent and complete,
and
the direct implication is: For any mathematical system, the consistent mathematical statements are unprovable within the system.
Godel’s 2nd theorem of incompleteness suggest:
————————————————————-
For any formal effectively generated theory, which includes basic arithmetical truths and also certain truths about formal provability, if the theory includes a statement of its own consistency then the theory is inconsistent.
A small explanation:
—————————
One can “ONLY” prove unless and until one is in the domain of “contradictions”. However, the moment one come to the domain of “consistency” then one can have a ONLY a “relative truth” , which is kind of the “data fitting model”. So as long as one is in the domain of consistency, one CANNOT prove anything with “Absolute truthfulness” .
A simple example:
———————-
If one has a calculator which can take two inputs “a” and “b” and then it produced a results “c” which a simple addition of “a+b”. Then one can prove from calculator (containing the algorithm of addition as a “first principle”) all other mathematical theorems which originate from the principle of “addition”, but one would be left with a major problem: One would never be able to prove the principle of addition, because it has been taken as a “first principle” and the journey started from there on wards. Now, if one has to prove the “first-principle” of addition, then one has to go beyond the boundaries of the “first principles”, which (in the present case) is the principle of “addition”. In that domain (beyond the domain of addition), there may also exists a calculator which can take the same inputs “a” and “b” but this time it would not add but subtract. Which is in a sense, a contradiction to what has been initially thought. So with in the domain of “addition” calculator, one would find an outstanding consistency with regard to the “addition” but “no absolute prove” and hence no absolute truth.
One implication:
——————-
Even if, one has all the resources, it has been mathematically proven in the field of mathematical logic that one will not never be able to prove (find) the “first principles” that are playing role in the existence of this very world (perceived as a reality). However, in order to so so one has to go into a domain, where exists the contradiction to those laws that are the very foundation of ones own existence.

Idrees Azad سچی بات ہے سمجھ نہیں آیا۔ دو نہیں۔ تین بار پڑھا ہے۔ آپ کے بیان میں کمزوری نہیں۔ میرا ہاتھ ریاضی میں تنگ ہی رہا ہے۔ لیکن ایک تأثر سا ملا ہے۔
if the theory includes a statement of its own consistency then the theory is inconsistent.

Syed Fawad Bokhari First principle is a fundamental proposition or postulate that serves as the starting points of any other proposition and it cannot be deduced from any other proposition or postulate.
In mathematics the postulate is a starting point of reasoning.

حمید نیازی Weekend par sunte hain aor baat hoti hai. More interested in conceptualizing the theorem for my understanding rather than the actual technical proof which in some case spans many branches of mathematics even for a one liner elegant problem like Fermat’s Last Theorem.
