The science of logic, considered one of the most important branches of philosophy, helps people think, form critical thinking and draw correct conclusions through mental observations. The science of logic is one of the oldest branches of science and was formed as a separate science by the great Greek philosopher Aristotle. Eastern thinkers of the early Renaissance period made a great contribution to the development of the science of logic along with various fields of science in their scientific activities. In this article, Fakhr al-Din al-Razi (d. 1210), who was a worthy follower and follower of such famous Eastern peripatetics as Farabi and Ibn Sina, an Eastern thinker, analyzed his attitude to the science of logic, as well as his logical views. For many years, the scientific heritage of Fakhriddin Razi was in desolation, and his works on the science of kalam were mainly studied and widely studied. However, his philosophical and logical outlook and his spiritual heritage have been studied very little. Today, due to the large-scale attention to science in our country, we have set ourselves the task of exploring the thoughts of Fakhr al-Din al-Razi about the correctness of conclusions, types of judgments and syllogisms in his logical views. To implement noble goals and ideas, such as the correct formation of a religious worldview in the minds of the growing youth, getting rid of one-sided decision-making, the ability to deal with various information attacks, and the service of modern science to the development of society. Fakhr al-Din al-Razi's opinion will be of great importance in development.
