    Once you say "transcendental", you are already outside the system itself. What does "transcendental" even mean within a formal system?alcontali
    I am trying to express myself - as much as possible - within your framework. Here is what you said a while back:
    Religion also proclaims the transcendental origin of this system of rules, necessarily from outside its formal system of rules.alcontali

    I take this to mean that there are axioms outside the formal system of Islamic Law upon which the laws are based - and that these axioms come from Allah. Am I getting this correct - or am I at least close?

    BTW - in your response it's not necessary to cite any scripture - I'm a plain language person - I trust that your explanations are correct. :smile:

    Maybe Allah doesn't want us to look for signs, since he doesn't a priori let us know what signs to look for. A great civilization might look great, but as with the "who is smart" question you bring up, intelligence has much to do with how happy you make yourself and others. There is a lot of factors that go into smartness. Just because Islam has the track record of generation after generation keeping the Koran pure, that doesn't mean it's the right religion. Rome so far hasn't proven it doesn't have infallible authority all these years, which could happen by dogmatic contradictions. If you were one who is open to actual miracle claims as proof of divine favor, Christianity has a pretty good case, and Catholicism too after you become a general Christian

    Yes, I guess that this is probably quite correct.

    It is a bit a similar situation to what you see in mathematics.

    There is no justification whatsoever for the axioms of number theory or set theory from within these theories. However, you will still find serious attempts at justification from within the philosophy of mathematics for its ontology.

    These ontological considerations are never considered part of mathematics proper. They are not even considered part of metamathematics (which intriguingly, is part of mathematics proper).

    The relationship between religious law (formal system) and the transcendental areas in religion (informal views) is the same as between mathematics (formal system) and the ontological philosophy of mathematics (informal views).

    It rejoins the general case that at the highest level of understanding there are no formal systems and there are no formal justifications.

    According to Islamic theology, human beings are born with an innate inclination of tawhid (Oneness).Fitrah in the ontology of Islam

    mathematics is an exercise of the human intuition, not a game played with meaningless symbols.Intuitionism in the ontology of mathematics

    Still, "the origins of X" debate can easily confuse the matter. That is why I try to avoid it. There is not one, single opinion at that level of understanding.

    I simply prefer to work with the formal systems themselves. I am particularly attracted to the mechanical verification of theorems within these formal systems by using the Coq proof assistant.

    Belated response here. I think I'm following this - Fitrah is an axiom.

    So next question. How do we go from this axiom all the way to the numerous laws that regulate our behavior to one another? I understand how this works in math. How does it work in Islam? E.g., how does Islam derive the laws governing marital relations from Fitrah? Are there extra axioms and/or steps involved?

    In mathematics it is relatively easy to find the basic rules of a theory structured as axioms. The following are the dominant axiomatizations in mathematics:


    There are many more. The following is the dominant axiomatization of logic:


    The axiomatization of logic gives the basic rules for the standard formal language used by the other mathematical axiomatizations (There are other formal languages possible). Hence the quite special status of logic in mathematics and in other axiomatic disciplines. The standard formal language in mathematics is first-order logic.

    You can find lots of examples of various axioms in these three standard axiomatizations. Simple example of an axiom:

    5 + 3 = 3 + 5

    You can swap the order of operands in a sum. Generally:

    a + b = b + a, for any a,b being a natural number.

    Standard number theory will define what the term "natural number" means, up to final interpretation by an actual natural-number model. A model is also called: an interpretation, a universe, or a world.

    The standard model of natural numbers is a regular language such as for example:

    = 0 | [1-9] [0-9] *

    along with the symbols (+, x).

    You can pick any number of arbitrary, distinct symbols , two or more, in order to define a collection of strings that represent the natural numbers:

    = | [ - ] [ - ] *

    along with two arbitrary, distinct symbols (⨁,⊗), that will satisfy the standard theory of natural numbers (PA).

    If you get used to the terminology, it can be relatively easy to learn to think in terms of axioms. Outside mathematics, axiomatic systems are also possible but have never been seriously formalized. So, their nature may be clearly axiomatic but they do not use symbolic language to express themselves.

    I may be misunderstanding you (or there may simply be gaps in my knowledge of Islam), but from where I'm sitting there seems to be a contradiction in your writing.

    Here's what you said in a response to @Nobeernolife:
    You see, Islamic law is a complete formal system with rules concerning morality.alcontali
    However, in your last reply to me, you stated that the Quran - and presumably all the laws therein - consists only of axioms. I think you would agree with me that a list of axioms does not constitute a formal system.

    Are there an additional set of laws in Islam that are derived from the Quran? Perhaps analogous to the Talmud?
  • alcontali

    No, it does.

    A formal system is a list of axioms.

    Such formal system is always augmented with a choice of logic system, which is by default first-order logic.

    A formal system is used for inferring theorems from axioms according to a set of rules. These rules, which are used for carrying out the inference of theorems from axioms, are the logical calculus of the formal system. A formal system is essentially an "axiomatic system".[1] In 1921, David Hilbert proposed to use such system as the foundation for the knowledge in mathematics.[2] A formal system may represent a well-defined system of abstract thought.Wikipedia on the term formal system

    Since the choice of logic is pretty much always the same, it is often not even mentioned.

    In mathematics, an axiomatic system is any set of axioms from which some or all axioms can be used in conjunction to logically derive theorems. A theory is a consistent, relatively-self-contained body of knowledge which usually contains an axiomatic system and all its derived theorems.[1]Wikipedia on axiomatic system

    In Islam, the Quran is a set of axioms while religious law ("al fiqh") is the (axiomatic) theory that emerges from the Quran. The Sunnah is considered to be already a set of theorems derived from the Quran and its use is therefore limited to a clarifying role.

    I could quibble with you over the definition of a formal system. Is a list of axioms by itself without a mechanism to generate theorems a formal system? I'm not qualified to answer that question, but if I had to maker a guess I'd say no.

    Meanwhile, I'll continue to attempt to work within your definitional framework. Let me echo back in my own words what I think you are saying:

    1) The Quran contains the axioms of Islam. These are transcendental in origin (your words) and not subject to question or dispute.
    2) The Sunnah contains the theorems. These theorems are derived from the Quran, but they also rely on the Hadith for supporting evidence.
    3) Finally, there is Fiqh which - quoting WIkipedia - "is human understanding of the divine Islamic law as revealed in the Quran and the Sunnah". So this is sort of the day to day interpretation of the Sunnah when the need arises to handle situations that cannot be easily decided by the Quran or the Sunnah.

    There are multiple versions of both the Hadith & Sunnah and different denominations of Islam use certain versions and not others. Regarding the Fiqh (and again according the Wikipedia) there are "four prominent schools (madh'hab) of fiqh within Sunni practice, plus two (or three) within Shi'a practice."

    I know you are deeply suspicious of organized schools of thought (since they typically become politicized) and consider yourself to be ghair-madhhabi - so no need to re-state that :smile: .

    At this point in the conversation I just need to know if my understanding is reasonably close for an outside observer.

    The mechanism to generate theorems from axioms is the system of logic:

    assert Syllogism {
      all Socrates: univ, Man, Mortal: set univ |
          -- every man is mortal
          Man in Mortal
          -- Socrates is a man
          and (Socrates in Man)
          -- implies Socrates is mortal
          implies Socrates in Mortal
      }
    check Syllogism
    

    These theorems are derived from the Quran, but they also rely on the Hadith for supporting evidence.EricH

    Hadith and Sunnah are often used as synonyms for each other.

    I have looked it up in Quora, but apparently that view is considered not to be completely correct.

    Hadith are testimonies about the prophet's life in which he applies the Quran. So, the Hadith are mostly theorems. The Sunnah, however, are practices transmitted from Mosaic Judaism mentioned in the Hadith. Therefore, part of the Sunnah are also considered to be axioms.

    Hence, there is some justification to accept the view that the Hadith is often the 'vehicle' which conveys information about the 'Sunna'. ... There is a fundamental difference between the Hadith and Sunna and though often used synonymously, should be kept distinct. ...Difference between Hadith and Sunna

    But then again, the Quran mentions all axioms already, even when they were transmitted from Mosaic Judaism:

    It is clear that the Quran does not support any type of 'Sunna' that does not find sanction from the Quran.Difference between Hadith and Sunna

    That is how we arrive at the simplifying view that the Quran are the axioms while (some of) the Hadith are clarifying, derived rules as applied to practical situations, i.e. theorems.

    It is possible to verify syllogisms from their premises, i.e. axioms, by using a tool like the Coq proof assistant:

    assert Syllogism {
      all Socrates: univ, Man, Mortal: set univ |
          -- every man is mortal
          Man in Mortal
          -- Socrates is a man
          and (Socrates in Man)
          -- implies Socrates is mortal
          implies Socrates in Mortal
      }
    
    check Syllogism
    

    This approach requires encoding the Quran, as system-wide premises, in the formal language of Coq. It is an inordinate amount of work, but it should allow to operate a Quranic formal system for the mechanical verification of (a subset of) the existing knowledge database of religious advisories. Curating that enormous knowledge database is another massive task. In fact, for mathematics proper, this curation and encoding work has been completed only very partially. With enough budget, however, I feel that it could also be done for Islamic law and yield very interesting results.

    So you would be mapping the text of the Quran into a set of symbols with no semantic content?EricH

    When you look at logic sentence such as:

    Man in Mortal and (Socrates in Man) implies Socrates in Mortal
    

    You can see that the conclusion is a syntactic entailment of its premises. The symbols actually themselves do not matter. It would also work perfectly-well like this:

    x in k and (s in x) implies s in k
    

    In the end, the reason why this syllogism entails is entirely structuralist:

    Structuralism is a position holding that mathematical theories describe structures, and that mathematical objects are exhaustively defined by their places in such structures, consequently having no intrinsic properties.Wikipedia on mathematical structuralism

    That is because the symbols are "alpha-equivalent":

    A basic form of equivalence, definable on lambda terms, is alpha equivalence. It captures the intuition that the particular choice of a bound variable, in an abstraction, does not (usually) matter. For instance, λx.x and λy.y are alpha-equivalent lambda terms, and they both represent the same function (the identity function).Wikipedia on alpha equivalence (lambda calculus)

    So, yes, actual semantic content does not matter in the context of syntactic entailment.

    However, a system with large numbers of sentences written in the second, nondescript manner would be much harder to debug. Software is not just written for only the machine to read. It must also be suitable for other people to read, so that it can be troubleshooted and maintained.

    Therefore, both a religious script representing a religious advisory as well as the Quranic base library are just like other software. On the one side, they are purely structuralist, but on the other side, they are also meant to communicate to other religious programmers what the otherwise alpha-equivalent symbols are all about.
