For Plotinus, the human face is that part of the body where the light of intelligibility can be shown through in the best way. It is why the face is beautiful, and, for this reason, it can be compared to the most beautiful things of the world. The stars, for example. But an issue raises immediately: when the face is compared to things of beauty, is not the actual meaning of the human face that could be lost? This question can be thought again in the Christian world, and also, thanks to Emmanuel Levinas, in the contemporary philosophy.

Paradox of the Evil and "Family Ressemblances". The paper tackles the problem of Matter and evil in Plotinus. monistic metaphysics, especially in theperspective of the following aparent inconsistency: if there is no other principle but the Good, then the Good creates the Matter which is the absolute evil. Itfollows that the Good is bad, according to a certain axiom of Proclus, which states that the creator is to a higher degree all what the creature is. The authorshows that, despite what Proclus and then many modern critics believed, Plotinus is consistent within his system. He relies on the axiom that the creature is not all what the creator is, i.e. that the creator also gives what he has not. Therefore, the One gives the Intellect multiplicity and thought which He is deprived of and also gives the Matter the evil which He is also deprived of. The paper also shows that Plotinus developed a logic of ontological procession which is not Aristotelian. This logic does not work by formind classes, but chains of partially intransitive ressemblances. So, the Intellect ressembles the One (the Good), the Soul ressembles the Intellect and the Matter ressembles the Soul; yet the Matter resembles the One no more. Yet, the unity of the world is assured, because of the continuity of the chain. The extreme terms are contrary, though not in the Aristotelian sense of sharing in the same genus. A certain similarty with Wittgenstein's logic of "family resemblances" is striking, which means that not only Wittgenstein, but Plotinus also went beyond the Platonic-Aristotelian Vulgata, even while he was sticking to its linguage.
