Philosophical dialogue as a genre generated by ancient culture has become an integral part of F. M. Dostoevsky’s novels. There it acquired a distinctly religious character. In this sense, the theory of M. M. Bakhtin about polyphonic dialogue in Dostoevsky’s novels does not allow to fully explain its (dialogue’s) mystical-religious content, and even more so the hidden author’s modality – Christian assessment (“pointing finger, passionately raised”). Moreover, the question of faith in the polyphonic dialogue is not raised at all.
