It proceeds to state various changes in human understanding of religion, aesthetics, ethics, science, knowledge and human rights. Furthermore, this paper gives an account of Marin Držić’s biography, providing insight into his fascinating, but tempestuous life and numerous ways in which his achievements and failures had influenced his creative process. Marin Držić’s biography closely explains his dissent with the establishment of the Republic of Dubrovnik. The chapter entitled Držić’s philosophical vision presents an in-depth analysis of his unique worldview and detects various ways in which different philosophical theories governed his literary work.
