Tolkien's cosmogonic approach, highlighted through the literary work "The Silmarillion" and other works, reveals the complexity and intensity of his philosophical vision of creation. He created his own mythological world, enriched with numerous characters, languages and myths. The concept of creation, expressed through Ilúvatar's Great Chant, explores the themes of creativity, harmony and destiny in the shaping of reality. This approach reveals how the process of creation is extremely connected to the moral and philosophical aspects of his works. He found his inspiration in the Catholic faith, as an important factor in personal development, which influenced his values and worldview, which was manifested in his literary achievements. In addition to being a writer, he was also an academic expert in two fields: philology and mythology. He used his knowledge and passion for these disciplines to enrich his literary world. An understanding of language and mythology further deepened his stories, providing powerful philosophical implications about human nature and creativity. Through this unique cosmogonic perspective, Tolkien left an indelible mark on the world of literature, encouraging readers to think more challengingly about the nature of creation, art and morality.
