This work consists of a reading of the novel The Brothers Karamazov, by Fyodor Dostoevsky, in the key of four essays and a brief introduction to the author polyphonic universe, based on the ideas of Mikhail Bakhtin, Nicolai Berdyaev and Luiz Felipe Pondé. Although intertwined, the essays can be read as standalone texts and do not pretend to defend a central argument; they aim mainly at expanding the possibilities offered by the hermeneutical object. It is a choice that takes into account the character of open work, resistant to systematization, as emphasized by numerous authors. The approach is interdisciplinary and dialogues with concepts from the fields of Literature (criticism and theory), Philosophy, Psychology and Theology, in line with the hypertextual nature of the novel, presenting a multiplicity of paths that remain unexplored and can be further developed by future researchers. The starting point is the concept of polyphony, which originates in the field of Literary Theory, with the writings of Bakhtin, but can be expanded and applied to a transdisciplinary reflection that involves elements of Jung s analytical psychology, the thought of Kierkegaard, Nietzsche and Camus and canonical texts of Orthodoxy and its contemporary interpreters. The thematic division of the texts follows the structure of the novel, based mainly in the conflict between reason and faith which gives rise to the dialogical confrontation between the brothers Ivan and Alyosha Karamazov and appears to be the highest concern of Dostoevsky in the last decades of his life, determining the basis of his rather peculiar approach on the problem of freedom, developed in detail in this work.
