Plotinos: Complete Works, v. 4 In Chronological Order,...

1. Must thought, and self-consciousness imply being composed of different parts, and on their mutual contemplation? Must that which is absolutely simple be unable to turn towards itself, to know itself? ls it, on the contrary, possible that for that which is not composite to know itself? Self-consciousness, indeed, does not necessarily result from a thing's knowing itself because it is composite, and that one of its parts grasps the other; as, for instance, by sensation we perceive the form and nature of our body. In this case the whole will not be known, unless the part that knows the others to which it is united also knows itself; otherwise, we would find the knowledge of one entity, through another, instead of one entity through itself.
