Abstract

The article is devoted to the presentation of the understanding of matter in the philosophy by Plotinus. It also constitutes an attempt to show a surface character of aporia of a hylemorphic structure of the noetic sphere. It points to the difference between a system function of aoristos dyas and noete hyle function from the perspective of dualism of existential principles. A characteristic of noetic matter presented in Enneads remains in an opposition to aoristos dyas constituting the principle of multiplicity and indefiniteness. A noetic matter determines the unity of a nous hyposthasis, and, as such, does not constitute the model of the matter of a sensual sphere. An understanding of the matter alone in the work by Plotinus is, basically, identified with an understanding of an aoristos dyas principle.
