The aim of this paper is to focus on the reception of Plotinus’ concept of matter in the Renaissance philosopher Giordano Bruno and his early Italian dialogue De la causa, principio et uno. I argue that Bruno’s concept of materia in De la causa, principio et uno reflects Plotinus’ theory of intelligible matter in Ennead ii 4 [12] 2–5 as well as Plotinus’ positive view of the perceptible world in Enneads ii 9 [33] and iv 8 [6]. It is suggested (...) that Bruno interprets Plotinus as an ancient philosopher who supported the unity and homogeneity of matter. Giordano Bruno’s reception of Plotinus in De la Causa, principio et uno could enlighten contemporary discussions in Neoplatonic studies concerning the question of matter in the Enneads. (shrink)
