This article highlights the educational and the aesthetic significance of the subject matter (i.e., "the third thing") in the relationship between teacher and pupil. This, through a reading of two texts, one written by the 19th century educationist and German philosopher Johann Friedrich Herbart, and one written by the contemporary philosopher and political theorist Jacques Rancière. By emphasizing the third thing between pupil and teacher, the article intends to reimagine both the educative and aesthetic values of those timeless things around us, such as objects of art and education, which give life a meaning beyond our limited socio-cultural desires, interests, concepts, and identities. Teaching, from this "fusion of the horizon" between Herbart and Rancière, is an activity created by the heterogeneity already integral to the "essence" of the subject matter. As such, the article also offers a fusion of the horizon between aesthetics and Didaktik.
