I forgot to add in the previous post that Hegel's Aesthetics can be found online here.
Also, In fact, the most fascinating of Hegel’s reflections on the concept of the concept occurs a little further on in the Aesthetics (p.22) in a discussion of the Idea of the Beautiful, where he speaks of the need to think beyond the ‘the emptiness, which clings to the Platonic idea’. The Platonic Idea is ‘empty’ in that it seems to have no describable positive content. It is an immobile Standard, never fully present in individual phenomenon but against which any individual beautiful thing can be judged and found wanting. For Hegel, however, the relation between universal and particular is altogether more immanent:
‘..in accordance with its own Concept, it [Idea of the Beautiful] has to develop into a totality of specifications, and it itself, like its exposition, contains the necessity of its particularizations and of their progress and transition into one another; on the other hand, the particularizations, to which a transition has been made, carry in themselves the universality and essentiality of the concept.’
Again, Hegel seems to imply that the concept is, so to speak, the blueprint for its own unfolding, or at least contains that blueprint. It ‘contains the necessity of its particularisations’. This ‘syntax' of particularisation, the necessary lines and branches mapped out by the Particulars, these constitute the concept, so that the question of the ‘relation’ between Particular and conceptual Universal is suddenly reframed. Is this formulation of the relation between particulars and universals not itself an aesthetic one?
What I mean by that last remark is that the 'aesthetic' is one name for what's happening when particulars do not simply & indifferently 'illustrate' some greater whole but, instead, the whole just is the constellation formed by the particulars.
