Additional archival materials are involved to answer several research questions. The author of this article provides arguments in favor of proving (...) that the manuscript is to be attributed to P. D. Yurkevych’s own handwriting, to be dated circa 1856, and that the purposing of its content is to be qualified as didactic. As it is established in the article, textual content of the manuscript in question is an original concise description and analysis of neoplatonic philosophy, which belongs to the set of materials created by P. D. Yurkevych in preparation for teaching the course on Ancient Philosophy in Kyiv Theological Academy during Kyivan period of his work. Turning to the inner critique of the manuscript, author of this article emphasizes an analysis that P. D. Yurkevych conducts concerning Plotinus’s ideas of the process of emanation of the world from the One and the role that philosophy has in true cognition. While comparing the manuscript “Neoplatonic Philosophy” with one of P. D. Yurkevych’s substantial philosophical works “Idea”, additional light is shed upon the prosess of genesis and development of Christian-Platonic worldview of the thinker.
