This paper traces the limits of the understanding of beauty as unified multiplicity in Plotinus' Enneads VI.2 and VI.6. These treatises can be read as insisting on the significance of multiplicity for beauty and as implying a distinction between the illuminated and the unilluminated beauty of Intellect.
In treatise VI.7, this distinction is made explicit and a deeper understanding of beauty as the manifestation of the Good in Intellect is introduced.
