The Philosophy and logic in Islamic thought, unlike Christian culture, developed uncensored and as a result of great demand. After the biggest translation movement in history, important components of Ancient Greek, Syriac, Persian, Jewish and Hindu cultures were transferred to Arabic. Kalam, which developed earlier in Islamic culture, has also been effective in understanding and accepting the philosophical content. In the beginning, translations were made in fields such as medicine, chemistry, astronomy and mathematics. Philosophy literature was also translated into Arabic due to its close relationship with other sciences and the need to fill the "gaps" in Islamic culture. The philosophy of logic was also transferred to Arab culture in its Aristotelian form. Especially the great influence of Aristotle helped strengthen the thought of logic among Arab philosophers and some theologians. As with other translation content, the logic has been translated into Arabic without any censorship. Contrary to the thinkers of Christian culture, Islamic philosophers learned all the subtleties of logic in a free intellectual environment, and as a result, this fact created a way for them to make a unique contribution to the discipline of logic. Logic, as it has been transformed into Arabic elements in Islamic culture, has been influential in basic areas such as theology, language, fiqh and kalam. In this process, logic, which was handled intertwined with traditional philosophy, has progressed to become a refined thought, especially with the influence of the first great philosopher Fârâbî. Fârâbî is not only a great philosopher but also a great Islamic scholar, and these qualities enabled him to adapt logic to Arab culture and Islamic sciences from his Aristotelian roots. Fârâbî, just like Aristotle, wanted to use logic as a criterion of truth for philosophical fields. Fârâbî, who designed logic under two main headings such as concepts and judgments, adapted logic to Arab culture for Muslims in the reasoning process. This solid construction of logic not only strengthened philosophical thought, but also contributed to the later establishment of a solid structure in Islamic sciences. In this context, the understanding of Islamic philosophy and its transformation with the effect of logic require a close examination of Fârâbî's thought. In our article, we will briefly discuss the pre-Islamic origins of philosophy and logic, and on this plane, we will examine Fârâbî's contribution to philosophy of some basic issues such as God, the classification of sciences, and the philosophical dimension of logic and try to reveal his effects on Islamic culture from a general point of view.

Logic, an old discipline with a long history, is a product of the nature of thinking that is based on mental thought, which is distinguished from other creatures by human nature. Logical thought and various forms of rational inference, seen in all the geographical regions of the world before attaining a systematic structure, have directed to human life and its scientific products. A systematic structure is taken back to Parmenides, lived in ancient Greek thought. The logic developed from various directions was given a proper shape by Aristotle nearly two thousand years ago and has been in continuous development and transformation in the direction of human mind and its needs. Today, in addition to Aristotelian logic, which is two most valuable structures, many valued logics have emerged.. Quite different logic conception emerges from classical logic, however, which is considered as a beginning for philosophical thought and is one of the important factors in reaching the goal of the philosophical effort. But the presence of classical logic continues in the areas of religious, classical philosophy and social sciences. In this frame, the value of classical logic from past histories requires the position that it deserves. Especially, in the area of logic as well as the problems faced in logic education, more effective planning is required especially in the higher education level. This article will briefly discuss the structure of logic and its various interpretations. It will also point out the importance of logic and will draw attention to the problems in the Theology Faculties. A few suggestions that we want to discuss in this framework will also be put forward.

In the process that followed the evolution of ancient Greek thought from mythology to a systematic philosophy, Parmenides, the founder of the Elea school, built up his thoughts with theses that were the exact opposite of his time and perhaps common sense in general. His famous poem On Nature, in the light of the logical principles, inferences, and analyses it contains, has profoundly influenced both epistemologies in terms of structure and possibility, and ontologies within the framework of time, space, and movement. In the mentioned period, the logical internal consistency of Parmenides and his followers, and the rational level in their arguments shaped the ancient period. The role he played especially in natural philosophy and metaphysics is undeniable. However, the ambiguities in the context of the theses and their interpretations of his poem, the only work that has been quoted, have not been resolved until today. The dimensions of this mystery are not only related to classical thought. Ontologies related to physics approaches, theoretical and institutional beliefs about them, and various cosmogony and language understandings can be related to Parmenides in some way. It is also possible to find in Parmenides's early forms some of the contents that form the basis of the philosophy of logic and has metaphysical roots constructed by Aristotle in the ancient period and for which he gained a well-deserved reputation. In addition to the deductive approach, especially the law of contradiction, the principle of identity, the law of excluded third, and the principles of sufficient reason are the most important concepts among those mentioned. These principles, which are not directly formulated, have been used in the context of Parmenides’ arguments about knowledge, existence, and related concepts. In our study, by touching on the significant points of the poem written by Parmenides, we will try to examine the conceptual uses and logical structures of the principles we have expressed and follow the traces of the process in question, and examine its effects. The main reason for this effort is that the content presented by Parmenides continues to be discussed today, maintained its influence in many areas mentioned above, and is an important cornerstone in the development of philosophy.
