## What is the Axiomatic Method?

Any set of axioms or postulates from which some or all axioms or postulates can be used in conjunction to logically derive theorems is known as an axiomatic system. A theory is a coherent, self-contained body of information that usually includes an axiomatic system and all of its derivations. A formal theory is an axiomatic system that defines a set of sentences that is closed under logical implication. It is typically formulated within model theory.

Indicating definitions and proposals in order to formally eliminate each new term by the terms previously introduced requires primitive concepts of axioms or postulates to prevent endless regression. This is called the axiomatic method of mathematics.

The axiomatic method has the significant advantage of making our initial conclusions completely clear. In addition, to set theory, the axiomatic method has been useful in other fields. Consider the case of plane geometry. It is possible to discuss lines and triangles without relying on axioms. However, the benefits of axiomatizing geometry were recognised early in the subject's history.

Beginning in the nineteenth century, the modern idea of the axiomatic method emerged as part of the conceptualization of mathematics. The method's basic concept is to capture a collection of structures as templates for an axiomatic system. The mathematical analysis of such groups of structures is not limited to the derivation of theorems from axioms, but usually involves the axiom system's metatheory. This interpretation of axiomatization meets the critical criterion that the derivation of theorems from axioms does not generate new knowledge in the traditional sense of the word.

Surface information is a type of information that can be created using the axiomatic method. The concept of axiomatization, when properly understood, does not refer to purely logical theories. The only axiomatization that matters, in this case, is a recursive enumeration of logical truths. Axiomatic set theories of the first order are not true axiomatizations. The key explanation is that their models are made up of particular structures rather than sets. The axiomatization is also not epistemologically driven, but it is linked to the concept of interpretation.

Axiomatization is the method of working backwards from a body of information to its axioms in mathematics. It is the formulation of a set of statements that relate a set of primitive terms in order to extract a set of coherent propositions deductively from these statements. Following that, every proof of a proposition can, in theory, be traceable back to these axioms.

The earliest extant axiomatic presentation of Euclidean geometry and number theory was written by Euclid of Alexandria. Non-Euclidean geometry, the foundations of real analysis, Cantor's set theory, Frege's work on foundations, and Hilbert's 'modern' use of the axiomatic method as a research tool were all established in the nineteenth century. For example, towards the end of the century, group theory was given an axiomatic framework. Once the axioms were explained, such as the need for inverse components, the subject may proceed independently, without regard for the transformation group roots of those studies.

### Properties of Axiomatic System

If there are no contradictions in an axiomatic scheme, it is said to be consistent. That is, an argument and its negation cannot be derived from the system's axioms. Many axiomatic structures need consistency since the existence of contradiction allows any argument to be proved using the theory of explosion.

An axiom is considered independent in an axiomatic scheme if it is not a theorem that can be deduced from other axioms in the system. If each of its underlying axioms is independent, the structure is said to be independent. Independence, unlike consistency, is not a criterion for a working axiomatic system, though it is sometimes tried to reduce the number of axioms in the system.

A full axiomatic system is one in which any statement, either itself or its negation, can be deduced from the system's axioms, or in other words, every statement can be proved true or false.

### Issues of Axiomatic Method

A definable set of axioms cannot catch any clear body of propositions. A set of axioms is said to be recursive in recursion theory if a computer programme can recognise whether a given proposition in the language is a theorem.

According to Gödel's first incompleteness theorem, there are some consistent bodies of propositions that do not require recursive axiomatization.

The machine can usually recognise the axioms and logical rules for deriving theorems, as well as whether a proof is true, but determining whether proof exists for an argument can only be done by waiting for the proof or disproof to be produced.

As a consequence, it will be impossible to determine the propositions are theorems, and the axiomatic approach will fail. The theory of natural numbers, which is only partly axiomatized by the Peano axioms, is an example of such a body of propositions.

Not every proof can be traced back to the axioms in fact. It's not always clear which set of axioms a proof is referring to. A number-theoretic argument, for example, could be expressed in arithmetic, and proof could be given that uses topology or complex analysis. It's not immediately clear if another proof can be found that is strictly based on the Peano axioms.

Any more-or-less randomly chosen set of axioms serves as the foundation of some mathematical theory, but such an arbitrary axiomatic system is unlikely to be free of inconsistencies, and even if it is, it is unlikely to illuminate something.

Mathematicians often claim that they chose axioms arbitrarily, but it's likely that, although they might seem arbitrary when viewed solely through the lens of deductive logic's canons, this appearance is due to a constraint on the purposes that deductive logic serves.

### Aristotle’s Syllogistic

The syllogism, according to Aristotle, is a discourse in which some things have been assumed, and something different from the things assumed follows as a result of necessity since these things are so. Despite this broad meaning, Aristotle restricts himself to categorical syllogisms with three categorical propositions, like categorical modal syllogisms, in Prior Analytics.

Syllogisms have been used as a method for comprehension since Aristotle's logical reasoning discussions. Prior to the mid-12th century, mediaeval logicians were only acquainted with a small portion of Aristotle's works, such as Categories and On Interpretation, which strongly influenced the dominant Old Logic.

For decades, Aristotle’s syllogistic dominated Western philosophical thought. The aim of the syllogism is to draw valid conclusions from assumptions (axioms), not to test the assumptions. People, on the other hand, tended to concentrate on the reasoning element over time, overlooking the importance of checking the assumptions.

### Conclusion

In logic, the axiomatic method is a technique for generating an entire system according to defined rules by logical deduction from certain basic propositions such as axioms or postulates, which are constructed from a few primitive terms. These terms and axioms can be described and constructed arbitrarily, or they can be conceived according to a model in which some intuitive support for their validity is felt to exist. Aristotle's syllogistic and Euclid's geometry are the first examples of axiomatized frameworks.

## FAQs on Axiomatic Method

1. What is the Axiomatic Method?

Ans: The axiomatic method emerged in the nineteenth century as part of the conceptualization of mathematics. The method's basic concept is to capture a collection of structures as templates for an axiomatic system. The mathematical analysis of such groups of structures is not limited to the derivation of theorems from axioms, but usually involves the axiom system's metatheory. This interpretation of axiomatization meets the critical criterion that the derivation of theorems from axioms does not generate new knowledge in the traditional sense of the word.

2. What is Axiomatization?

Ans: Axiomatization is a formal method for describing the substance of a theory in which a collection of axioms is given from which the rest of the theory's content can be deduced as theorems. The set of axioms and their deductive results, known as the closure of the axiom set, is associated with the theory.

3. What is Aristotle’s Syllogistic?

Ans: The author's Lingua Cosmica contains Aristotelian assertive syllogistic logic (without modalities). LINCOS represents the well-known basic structures of propositions and the conversions between them in this logic. Since these representations correspond to set-theoretic operations, LINCOS includes them as well. Four essential so-called perfect figures are obtained based on this valid argumentation in Aristotle's context.
