The history of the Budapest School is bound up with the history of the philosophic reception of Immanuel Kant. I will focus on this intersectional history as it has played out in the works of the two most prominent Budapest School members: György Lukács and Ágnes Heller. I will briefly sketch the trajectory of Kantianism as well as its rejection in Lukács’s works to show subsequently the ways in which his acceptance and rejection of Kant influenced the philosophic development of Heller. I will conclude with an analysis of Heller’s recent responses to Kant, namely in her aesthetic monograph The Concept of the Beautiful and in her discussions of her oeuvre in the anthology Engaging Ágnes Heller.
