The Idealist Conception

There are many ways to interpret Plato’s relation to classical aesthetics. 

The political system sketched in the Republic characterizes justice in terms of the relation of part and whole. But Plato was also no doubt a dissident in classical culture, and the account of beauty that is expressed specifically in the Symposium—perhaps the key Socratic text for neo-Platonism and for the idealist conception of beauty—expresses an aspiration toward beauty as perfect unity.

In the midst of a drinking party, Socrates recounts the teachings of his instructress, one Diotima, on matters of love. She connects the experience of beauty to the erotic or the desire to reproduce (Plato, 558–59 [Symposium 206c–207e]). 

But the desire to reproduce is associated in turn with a desire for the immortal or eternal: “And why all this longing for propagation? Because this is the one deathless and eternal element in our mortality. 

And since we have agreed that the lover longs for the good to be his own forever, it follows that we are bound to long for immortality as well as for the good—which is to say that Love is a longing for immortality” (Plato, 559, [Symposium 206e–207a]). What follows is, if not classical, at any rate classic:

The candidate for this initiation cannot, if his efforts are to be rewarded, begin too early to devote himself to the beauties of the body. First of all, if his preceptor instructs him as he should, he will fall in love with the beauty of one individual body, so that his passion may give life to noble discourse. 

Next he must consider how nearly related the beauty of any one body is to the beauty of any other, and he will see that if he is to devote himself to loveliness of form it will be absurd to deny that the beauty of each and every body is the same. Having reached this point, he must set himself to be the lover of every lovely body, and bring his passion for the one into due proportion by deeming it of little or no importance.

Next he must grasp that the beauties of the body are as nothing to the beauties of the soul, so that wherever he meets with spiritual loveliness, even in the husk of an unlovely body, he will find it beautiful enough to fall in love with and cherish—and beautiful enough to quicken in his heart a longing for such discourse as tends toward the building of a noble nature. And from this he will be led to contemplate the beauty of laws and institutions. And when he discovers how every kind of beauty is akin to every other he will conclude that the beauty of the body is not, after all, of so great moment. …

And so, when his prescribed devotion to boyish beauties has carried our candidate so far that the universal beauty dawns upon his inward sight, he is almost within reach of the final revelation. … Starting from individual beauties, the quest for universal beauty must find him mounting the heavenly ladder, stepping from rung to rung—that is, from one to two, and from two to every lovely body, and from bodily beauty to the beauty of institutions, from institutions to learning, and from learning in general to the special lore that pertains to nothing but the beautiful itself—until at last he comes to know what beauty is.

And if, my dear Socrates, Diotima went on, man’s life is ever worth living, it is when he has attained this vision of the very soul of beauty. (Plato, 561–63 [Symposium 210a–211d])

Beauty here is conceived—perhaps explicitly in contrast to the classical aesthetics of integral parts and coherent whole—as perfect unity, or indeed as the principle of unity itself.

Plotinus, as we have already seen, comes close to equating beauty with formedness per se: it is the source of unity among disparate things, and it is itself perfect unity. Plotinus specifically attacks what we have called the classical conception of beauty:

Almost everyone declares that the symmetry of parts towards each other and towards a whole, with, besides, a certain charm of colour, constitutes the beauty recognized by the eye, that in visible things, as indeed in all else, universally, the beautiful thing is essentially symmetrical, patterned.

But think what this means.

Only a compound can be beautiful, never anything devoid of parts; and only a whole; the several parts will have beauty, not in themselves, but only as working together to give a comely total. 

Yet beauty in an aggregate demands beauty in details; it cannot be constructed out of ugliness; its law must run throughout.

All the loveliness of colour and even the light of the sun, being devoid of parts and so not beautiful by symmetry, must be ruled out of the realm of beauty. And how comes gold to be a beautiful thing? And lightning by night, and the stars, why are these so fair?

In sounds also the simple must be proscribed, though often in a whole noble composition each several tone is delicious in itself. (Plotinus, 21 [Ennead I,6])

Plotinus declares that fire is the most beautiful physical thing, “making ever upwards, the subtlest and sprightliest of all bodies, as very near to the unembodied. … Hence the splendour of its light, the splendour that belongs to the Idea” (Plotinus, 22 [Ennead I,3]). 

For Plotinus as for Plato, all multiplicity must be immolated finally into unity, and all roads of inquiry and experience lead toward the Good/Beautiful/True/Divine.

This gave rise to a basically mystical vision of the beauty of God that, as Umberto Eco has argued, persisted alongside an anti-aesthetic asceticism throughout the Middle Ages: a delight in profusion that finally merges into a single spiritual unity. 

In the sixth century, Pseudo-Dionysius the Areopagite characterized the whole of creation as yearning toward God; the universe is called into being by love of God as beauty (Pseudo-Dionysius, 4.7; see Kirwan 1999, 29). 

Sensual/aesthetic pleasures could be considered the expressions of the immense, beautiful profusion of God and our ravishment thereby. Eco quotes Suger, Abbot of St Denis in the twelfth century, describing a richly-appointed church:

Thus, when—out of my delight in the beauty of the house of God—the loveliness of the many-colored gems has called me away from external cares, and worthy meditation has induced me to reflect, transferring that which is material to that which is immaterial, on the diversity of the sacred virtues: then it seems to me that I see myself dwelling, as it were, in some strange region of the universe which neither exists entirely in the slime of the earth nor entirely in the purity of Heaven; and that, by the grace of God, I can be transported from this inferior to that higher world in an anagogical manner. (Eco 1959, 14)

This conception has had many expressions in the modern era, including in such figures as Shaftesbury, Schiller, and Hegel, according to whom the aesthetic or the experience of art and beauty is a primary bridge (or to use the Platonic image, stairway or ladder) between the material and the spiritual. 

For Shaftesbury, there are three levels of beauty: what God makes (nature); what human beings make from nature or what is transformed by human intelligence (art, for example); and finally, the intelligence that makes even these artists (that is, God). 

Shaftesbury’s character Theocles describes “the third order of beauty,” which forms not only such as we call mere forms but even the forms which form. 

For we ourselves are notable architects in matter, and can show lifeless bodies brought into form, and fashioned by our own hands, but that which fashions even minds themselves, contains in itself all the beauties fashioned by those minds, and is consequently the principle, source, and fountain of all beauty. … 

Whatever appears in our second order of forms, or whatever is derived or produced from thence, all this is eminently, principally, and originally in this last order of supreme and sovereign beauty. … 

Thus architecture, music, and all which is of human invention, resolves itself into this last order. (Shaftesbury 1738, 228–29)

Schiller’s expression of a similar series of thoughts was fundamentally influential on the conceptions of beauty developed within German Idealism:

The pre-rational concept of Beauty, if such a thing be adduced, can be drawn from no actual case—rather does itself correct and guide our judgement concerning every actual case; it must therefore be sought along the path of abstraction, and it can be inferred simply from the possibility of a nature that is both sensuous and rational; in a word, Beauty must be exhibited as a necessary condition of humanity. Beauty … makes of man a whole, complete in himself. (1795, 59–60, 86)

For Schiller, beauty or play or art (he uses the words, rather cavalierly, almost interchangeably) performs the process of integrating or rendering compatible the natural and the spiritual, or the sensuous and the rational: only in such a state of integration are we—who exist simultaneously on both these levels—free. 

This is quite similar to Plato’s ‘ladder’: beauty as a way to ascend to the abstract or spiritual. 

But Schiller—though this is at times unclear—is more concerned with integrating the realms of nature and spirit than with transcending the level of physical reality entirely, a la Plato. It is beauty and art that performs this integration.

In this and in other ways—including in the tripartite dialectical structure of his account—Schiller strikingly anticipates Hegel, who writes as follows.

The philosophical Concept of the beautiful, to indicate its true nature at least in a preliminary way, must contain, reconciled within itself, both the extremes which have been mentioned [the ideal and the empirical] because it unites metaphysical universality with real particularity. (Hegel 1835, 22)

Beauty, we might say, or artistic beauty at any rate, is a route from the sensuous and particular to the Absolute and to freedom, from finitude to the infinite, formulations that—while they are influenced by Schiller—strikingly recall Shaftesbury, Plotinus, and Plato.

Hegel, who associates beauty and art with mind and spirit, holds with Shaftesbury that the beauty of art is higher than the beauty of nature, on the grounds that, as Hegel puts it, “the beauty of art is born of the spirit and born again” (Hegel 1835, 2). 

That is, the natural world is born of God, but the beauty of art transforms that material again by the spirit of the artist. 

This idea reaches is apogee in Benedetto Croce, who very nearly denies that nature can ever be beautiful, or at any rate asserts that the beauty of nature is a reflection of the beauty of art. 

“The real meaning of ‘natural beauty’ is that certain persons, things, places are, by the effect which they exert upon one, comparable with poetry, painting, sculpture, and the other arts” (Croce 1928, 230).
