Abstract

In its first part, this paper deals with some passages of the Eneads in which the notions of consciousness and unconsciousness may be found. In spite of not having terms that correspond exactly to these in Greek, it is clear that Plotinus had very refined notions related to them, going up to indicate that consciousness might not be the epistemological function that defines humans. The multiple aspects of the phyché hyposthesis in Plotinus enables this separation between consciousness and the essence of men. In its second part, this paper describes cosmological elements of the notions of consciousness and unconsciousness in Plotinus, since the celestial bodies are admitted as living beings. This paper indicates, finally, some problems related to astrology in Plotinus concerned with the notion of consciousness of the stars.
