- MakaleAçık Erişim2026Ibn Kammūna's Understanding of Propositions*
Akbay, Yunus Emre; Evmes, Adem; Akyüz, Turgut
The subject of this article is to examine and analyze the understanding of propositions held by Ibn Kamm & umacr;na, who lived in the 13th century, from the perspective of the discipline of logic. Ibn Kamm & umacr;na is a profound thinker who left significant works in the fields of philosophy and logic by thoroughly examining the works of figures such as Ibn Maym & umacr;n, Ibn Sin & amacr;, al-Ghaz & amacr;li, Ab & umacr; al-Barak & amacr;t al-Baghd & amacr;di, Fakhr al-Din al-R & amacr;zi, and al-Suhrawardi. The primary aim of the article is to analyze in detail the manner in which Ibn Kamm & umacr;na approaches propositions, drawing upon the works he authored on matters of logic. The scope of the article is confined to al-Jad & imacr;d f & imacr;'l-hikma, Sharh al-us & umacr;l wa'l-jumal, and Sharh at-talw & imacr;h & amacr;t, which are among Ibn Kamm & umacr;na's works containing data on the subject of propositions, and within the context of these works, the definition of the proposition, categorical propositions, conditional propositions, modal propositions, the contradiction and conversion of propositions are comprehensively addressed. The literature review conducted revealed that the philosopher has been examined to a considerably limited extent in our country from the standpoint of logic, and this study is considered to make a significant contribution to remedying the aforementioned deficiency. A qualitative research methodology was adopted in the article, and techniques of analysis and comparison were employed. It is known that Ibn Kamm & umacr;na, unlike authors such as Aristotle, al-F & amacr;r & amacr;bi, and Ibn Sin & amacr;, did not compose an independent work on propositions. For this reason, approximately sixteen works that have survived to the present day were meticulously examined through an individual scanning method, passages related to the subject of propositions within the context of the three identified works were recorded, and the data obtained were systematically classified and analyzed. As a result, it has been demonstrated that Ibn Kamm & umacr;na's treatment of propositions draws substantially from the Peripatetic tradition through Ibn Sin & amacr;. Ibn Kamm & umacr;na shares a common view with Ibn Sin & amacr; on the matter of indefinite propositions and explicitly states that such propositions ought to be understood as particular. Furthermore, he addresses propositions holistically on the subject of modality without making a distinction between simple and composite; and emphasizes that there is no limitation with respect to the number of modal propositions and
- MakaleAçık Erişim2026The Art of Dialectic (Jadal) in Ibn al-Mutahhar al-Hillī
Evmes, Adem; Akbay, Yunus Emre; Akyüz, Turgut
Al-Hilli, known as a Shii theologian and legal theorist, was a versatile scholar of the thirteenth century who authored numerous works on the philosophical sciences. In his writings, al-Hilli carefully examined ontological problems and methodological questions, systematically discussed the problem of knowledge, and devoted considerable attention to the science of logic. This article addresses al-Hilli's views on the art of dialectic (jadal), which he considered necessary for those who have not yet attained the level of demonstration (burhan), which ranks second in importance among the five arts, and on which no dedicated study has hitherto been undertaken. The aim of the article is to determine, on the basis of his logic works composed within the Peripatetic (Mash'sha'i) tradition, the extent to which al-Hilli was influenced by earlier logicians in his understanding of jadal and the respects in which he diverged from them. The scope of the article is confined to three of al-Hilli's works: his commentary on the logic section of Nasir al-Din al-Tusi's Tajrid al-i'tiqad, entitled al-Jawhar al-nadid; his commentary on al-Katibi's logical treatise al-Shamsiyya, entitled al-Qawa'id al-jaliyya; and his independent composition al-Asrar al-khafiyya fi al-'ul & umacr;m al-'aqliyya. These works were examined through a single-subject scanning method, whereby passages containing data pertaining to the components of dialectical theory-including its definition, premises, structure, and application-were identified and analysed. In this context, recourse was made to the works of logicians who had written on jadal prior to al-Hilli, among them Aristotle, al-Farabi, Ibn Sina, al-T & umacr;si, and al-Katibi, with particular attention given to a comparative analysis of the explanations offered by Ibn Sina and al-Hilli. It was ultimately established that al-Hilli followed both the Aristotelian and the Peripatetic logical tradition in his theory of jadal, and that he was especially influenced by Ibn Sina.

In the first part of this study, which consists of two parts, the introduction of the fuzzy inverse logic method, its foundations, computation and process flow and details were given. In this second part, the method was applied on a very simple mathematical problem and on a simple civil engineering design problem in order to investigate and evaluate the validity of the method easily. Fuzzy inverse logic computations have been carried out on these two simple problems for different dimension, sensitivity and acceptable error values. By comparing the obtained results with the desired outputs and mathematical results, the effective computation ability of the method was tried to be revealed. As a result, it is understood that the method developed in this study has many promising aspects in terms of theoretical computations and practical applications and can be used effectively in many scientific fields.

İncele - MakaleAçık Erişim2021Fuzzy inverse logic: part-1. introduction and bases; [Bulanık ters mantık: kısım-1. giriş ve temeller]
Öztekin, Ertekin
In almost all deterministic and artificial intelligence techniques, for the solution of the scientific problems such as design and control problems, the output estimations are performed depending on manuplations on the values of input variables. With the other words, lots of different values derived from input parameters are tried in order to obtain desired output(s). Contrary to these conventional estimation methods, this study consists of two parts in which a new artificial intelligence method called fuzzy inverse logic(FIL) is developed to determine or estimate the value of the input parameters that give the targeted problem output. In the first part of this study, after providing a brief overview about the method of classical fuzzy logic(FL), the solution approaches and calculation details about FIL are given. In the second part of the study, fuzzy inverse logic method was used to solve one simple mathematical problem and one simple civil engineering problem. After the validity of the developed method was demonstrated by graphics and tables. some evaluations were made about the method.
