Abstract
This article is devoted to determining the source potential of the so-called dissertations collection of the Kyiv Theological Academy in the study of its philosophical heritage. The author draws attention to the distinction of the hierarchy of educational and academic degrees in the Russian Empire the first, candidate’s degree, not being a research degree, from today’s hierarchy. The candidate’s degree at that time was awarded to graduates of higher education institutions on the basis of their academic achievements and a final work, which should be considered analogous to a diploma work, not to dissertations intended for public defense for a PhD degree. The article reveals that the collection of candidate papers from the Manuscript Institute contains important sources for researchers of biographies of the graduates of the Kyiv Theological Academy, its history, and academic heritage. Out of more than two thousand manuscripts stored in the Funds no. 304, the author has for the first time selected and systematized an array of candidate works on philosophical subjects, substantiating their important role in the research of the philosophical heritage of the Kyiv Theological Academy.
