Accordingly, Popper's falsifications view is similar to the common view of theologians and rationalists, who consider religious discussions and debates the main and effective factor in changing people's beliefs. In contrast to this view and relying on historical evidence, the change in the worldview of religious people has been considered similar to the change in the scientific paradigms of scientists from the perspective of Thomas Kuhn. In this way, it has been shown that, contrary to the traditional view of theologians, people do not change their beliefs (religion and sect) solely through theoretical discussions and theological proofs and refutations but are influenced by various social and psychological factors. It has also been shown that different religions and sects have incomparable worldviews, and, as a result, theological disputes are considered polemical debates between the two parties. Accordingly, in religious studies, Kuhn's perspective can be used to explain how individuals' religious attitudes change. Also, within the framework of faithism in the philosophy of religion, the question is answered: How do individuals choose their fait? Keywords: Philosophy of Science, Philosophy of Religion, Studies of Religions, Thomas Kuhn, Paradigm, Faithism. * Associate Professor, Islamic Philosophy and Kalam, Allameh Tabataba'i University, Tehran, Iran, Saeed.anvari@atu.ac.ir Date received: 02/11/2024, Date of acceptance: 29/12/2024
