Leo Tolstoy, the great Russian writer, explored the essence of human existence and the pursuit of moral perfection, standing as a pinnacle of realist literature. Through War and Peace and Anna Karenina, he delved deeply into the contradictions of society and the complexity of human emotion, intertwining reflections on freedom, conscience, and faith. In his later years, he developed a philosophy centered on nonviolence and self-discipline, rejecting materialism and social injustice. His ideas influenced figures such as Gandhi and extended far beyond literature into moral and spiritual reform. Tolstoy viewed art as a means of purifying the soul and fostering ethical growth in humanity.
