The relationship between language and being is one of the most intricate issues in the history of thought. Naming places at the center of this relationship. Human beings can only know existence and do science by naming it. Since knowing begins with naming, discussions on naming have been carried out in connection with epistemology, ontology, and metaphysics throughout the history of thought, transcending the limits of the linguistic plane. The fact that changes in the understanding of being also shape the understanding of language has led to changes in the theories of naming. In particular, Kant's criticisms of metaphysics deeply affected the naming theories in the modern period. Kant rejected the concept of substance existing independently, which had been accepted since antiquity, and introduced an understanding of an object constructed by the subject's judgment. This elimination also changed the position of proper names. Understanding proper names based on substance metaphysics became difficult to defend with the "linguistic turn." While this difficulty is in question for any name, when it comes to naming God, the issue gains a theological dimension and becomes even more intricate. The main question that this study seeks to answer is whether the modern theories of naming developed after Kant enable us to determine the referent of the proper name "Allah." Several studies have been written to investigate the possibility of referring to God with modern linguistic theories. In these studies, either the concept of "God", which is a universal concept (i.e., under which different individuals can be included), has been analyzed, or the possibility of referring to the "God" of Christianity and Judaism with the existing theories of reference has been investigated. However, there has not been an examination of how to refer to "Allah" as a proper name, considering the views of Islamic thinkers on the subject. Our study aims to fill this gap by including the statements of famous Islamic scholars on the subject with attention to metaphysical backgrounds. To investigate the possibility of naming "Allah" in the modern philosophy of language, it is necessary to reveal how the signification of the name "Allah" was determined in the classical period. There are two main approaches in Islamic thought on how the word "Allah" is a name. While one states that the word has become a name through descriptions, the other view defends the directness of this naming without the mediation of descriptions. While explaining these views defended by different names, we will mainly include the views of Fakhr al-Dīn al-Razi and alBayḍāwī, We will also draw attention to the metaphysical ground on which the explanations are based for their comparison with the modern period. This study does not purport to encompass all modern theories of reference developed after Kant. Considering their founding positions in the modern philosophy of language, we will first analyze Frege and Russell's descriptivist theory of reference and discuss whether it offers the possibility of reference to "Allah". The descriptivist theory presents an understanding in which proper names are reduced to descriptions. This understanding has been criticized for some of its limitations. The most famous of these criticisms is that of the logician Saul Kripke. Thanks to his proofs in modal logic, Kripke could talk about the "accessibility relation" and claim that proper names are strict determiners in all accessible worlds. Based on this idea, the causal theory of reference argues that proper names can name their objects without needing to mediate descriptions. In our study, we will analyze Kripke's views for two purposes. Firstly, we will reveal the limitations of the descriptivist theory through Kripke's criticisms. Our second but more primary aim is to investigate whether Kripke and his followers' theory of direct reference provides the possibility of reference to the word "Allah”. At this point, we will use the works of philosophers of religion, such as W. Alston and J. Gellman, who have worked on the subject of a reference to God. Some philosophers of religion, such as Miller, Alston, and Gellman, believe that the causal theory of reference is the most appropriate ground to explain the reference to God. In this study, we will examine their arguments in the context of Islamic thought. The study concluded that modern naming theories would be insufficient to name the word "Allah" with its classical meaning. The limitations of the theories in referring to any proper name are also valid for the word "Allah". However, our main claim at this point is that the main reason for the inadequacy is the changing understanding of existence between classical and modern theories. The lack of the idea of “thing in itself” independent of the subject in both the descriptive reference theory and the direct reference theory prevents the word "Allah" from referring to essence. Although our research is limited to the two theories mentioned above, it is assumed that all modern philosophies of language have the color of his thought since they were developed after Kant. However, the study does not claim that reference to God is impossible in the modern period. We propose constructing a new theory that can successfully explain that Lafzatullah (the Word of Allah) refers to “Allah” [ABSTRACT FROM AUTHOR]
