New methodological approaches to studying the philosophical heritage of al-Ghazali (1058-1111) are connected with the understanding of another culture as "a different culture and logic of thinking," the Arab-Muslim culture as a "phenomenon of cross-cultural interaction, the role of "the ideal of knowledge and cognitive attitude to reality" In the Muslim tradition. The article shows that the teaching of al-Ghazali on the relationship between faith and reason is the key to understanding the integrity of his teaching, within which existing antinomies show the regulative role of reason in philosophy and science, the possibility of subordinating theoretical reason to the practical, as well as the practical significance of his theory of the supermind In Sufism.
