The article is dedicated to the memory of Kostiantyn Dmytrovych Ushynskyi (1823-1871), an outstanding Ukrainian teacher-philosopher, founder and developer of the theoretical foundations of education based on the cooperation of pedagogy and psychology (the middle of the 19th century). In general, the purpose of the article is to update the scientific achievements of prominent compatriot. The article’s goal is detailed in such tasks: the assertion of Ukrainianness as the source or origin of K. Ushynskyi’s personality and creativity; the substantiation of the features of his life philosophy, mentality (the priority of the value of the human soul, heartcentred meaning of human being in the comprehension of life; high personal emotionality, but subject to will; love for the native foundations), which total combination nourished the thinker’s ideas about pedagogical anthropology; substantiation of the peculiar intertextuality of the K. Ushynskyi’s book “Man as an object of education. An attempt at pedagogical anthropology” (1868–1869); an attempt to characterize the worldview and philosophical meanings of K. Ushynskyi’s construction of the psychological and pedagogical foundations of the educational process (cultural conformity, nature conformity, activity as the basis of education), which remains not only the historical heritage of Ukrainian humanitarian thought, but also a variant of an anthropologically sharpened worldview landmark for modern educators. It has been established that in the documentary substantiation of K. Ushynskyi’s belonging to Ukrainian culture, the contribution of the modern local historian and teacher V. Terletskyi became the most important. It is shown that the appeals made by K. Ushynskyi to the thoughts, ideas, opinions of numerous European scientists, writers, historical figures, polemics and dialogues with them on the pages of the book ensured the transition to the creation of a text as a stereophonic intersection with other texts. The author of the article tries to substantiate this feature of the book as a kind of intertextuality of the analyzed scientific work.
