This article will begin with a sketch of the debate over whether beauty is objective or subjective, which is perhaps the single most-prosecuted disagreement in the literature. It will proceed to set out some of the major approaches to or theories of beauty developed within Western philosophical and artistic traditions.

The nature of beauty is one of the most enduring and controversial themes in Western philosophy, and is—with the nature of art—one of the two fundamental issues in philosophical aesthetics. Beauty has traditionally been counted among the ultimate values, with goodness, truth, and justice. It is a primary theme among ancient Greek, Hellenistic, and medieval philosophers, and was central to eighteenth and nineteenth-century thought, as represented in treatments by such thinkers as Shaftesbury, Hutcheson, Hume, Burke, Kant, Schiller, Hegel, Schopenhauer, Hanslick, and Santayana. By the beginning of the twentieth century, beauty was in decline as a subject of philosophical inquiry, and also as a primary goal of the arts. However, there were signs of revived interest by the early 2000s.

Perhaps the most familiar basic issue in the theory of beauty is whether beauty is subjective—located ‘in the eye of the beholder’—or whether it is an objective feature of beautiful things. A pure version of either of these positions seems implausible, for reasons we will examine, and many attempts have been made to split the difference or incorporate insights of both subjectivist and objectivist accounts. Ancient and medieval accounts for the most part located beauty outside of anyone's particular experiences. Nevertheless, that beauty is subjective was also a commonplace from the time of the sophists. By the eighteenth century, Hume could write as follows, expressing one ‘species of philosophy’:

Beauty is no quality in things themselves: It exists merely in the mind which contemplates them; and each mind perceives a different beauty. One person may even perceive deformity, where another is sensible of beauty; and every individual ought to acquiesce in his own sentiment, without pretending to regulate those of others. (Hume 1757, 136)

And Kant launches his discussion of the matter in The Critique of Judgment (the Third Critique) at least as emphatically:

The judgment of taste is therefore not a judgment of cognition, and is consequently not logical but aesthetical, by which we understand that whose determining ground can be no other than subjective. Every reference of representations, even that of sensations, may be objective (and then it signifies the real [element] of an empirical representation), save only the reference to the feeling of pleasure and pain, by which nothing in the object is signified, but through which there is a feeling in the subject as it is affected by the representation. (Kant 1790, section 1)

However, if beauty is entirely subjective—that is, if anything that anyone holds to be or experiences as beautiful is beautiful (as James Kirwan, for example, asserts)—then it seems that the word has no meaning, or that we are not communicating anything when we call something beautiful except perhaps an approving personal attitude. In addition, though different persons can of course differ in particular judgments, it is also obvious that our judgments coincide to a remarkable extent: it would be odd or perverse for any person to deny that a perfect rose or a dramatic sunset was beautiful. And it is possible actually to disagree and argue about whether something is beautiful, or to try to show someone that something is beautiful, or learn from someone else why it is.

On the other hand, it seems senseless to say that beauty has no connection to subjective response or that it is entirely objective. That would seem to entail, for example, that a world with no perceivers could be beautiful or ugly, or perhaps that beauty could be detected by scientific instruments. Even if it could be, beauty would seem to be connected to subjective response, and though we may argue about whether something is beautiful, the idea that one's experiences of beauty might be disqualified as simply inaccurate or false might arouse puzzlement as well as hostility. We often regard other people's taste, even when it differs from our own, as provisionally entitled to some respect, as we may not, for example, in cases of moral, political, or factual opinions. All plausible accounts of beauty connect it to a pleasurable or profound or loving response, even if they do not locate beauty purely in the eye of the beholder.

Until the eighteenth century, most philosophical accounts of beauty treated it as an objective quality: they located it in the beautiful object itself or in the qualities of that object. In De Veritate Religione, Augustine asks explicitly whether things are beautiful because they give delight, or whether they give delight because they are beautiful; he emphatically opts for the second (Augustine, 247). Plato's account in the Symposium and Plotinus's in the Enneads connect beauty to a response of love and desire, but locate beauty itself in the realm of the Forms, and the beauty of particular objects in their participation in the Form. Indeed, Plotinus's account in one of its moments makes beauty a matter of what we might term ‘formedness’: having the definite shape characteristic of the kind of thing the object is.

We hold that all the loveliness of this world comes by communion in Ideal-Form. All shapelessness whose kind admits of pattern and form, as long as it remains outside of Reason and Idea, is ugly from that very isolation from the Divine-Thought. And this is the Absolute Ugly: an ugly thing is something that has not been entirely mastered by pattern, that is by Reason, the Matter not yielding at all points and in all respects to Ideal-Form. But where the Ideal-Form has entered, it has grouped and coordinated what from a diversity of parts was to become a unity: it has rallied confusion into co-operation: it has made the sum one harmonious coherence: for the Idea is a unity and what it moulds must come into unity as far as multiplicity may. (Plotinus, 22 [Ennead I, 6])

In this account, beauty is at least as objective as any other concept, or indeed takes on a certain ontological priority as more real than particular Forms: it is a sort of Form of Forms.

Though Plato and Aristotle disagree on what beauty is, they both regard it as objective in the sense that it is not localized in the response of the beholder. The classical conception (see below) treats beauty as a matter of instantiating definite proportions or relations among parts, sometimes expressed in mathematical ratios, for example the ‘golden section.’ The sculpture known as ‘The Canon,’ by Polykleitos (fifth/fourth century BCE), was held up as a model of harmonious proportion to be emulated by students and masters alike: beauty could be reliably achieved by reproducing its objective proportions. Nevertheless, it is conventional in ancient treatments of the topic also to pay tribute to the pleasures of beauty, often described in quite ecstatic terms, as in Plotinus: “This is the spirit that Beauty must ever induce: wonderment and a delicious trouble, longing and love and a trembling that is all delight” (Plotinus 23, [Ennead 1, 3]).

At latest by the eighteenth century, however, and particularly in the British Isles, beauty was associated with pleasure in a somewhat different way: pleasure was held to be not the effect but the origin of beauty. This was influenced, for example, by Locke's distinction between primary and secondary qualities. Locke and the other empiricists treated color (which is certainly one source or locus of beauty), for example, as a ‘phantasm’ of the mind, as a set of qualities dependent on subjective response, located in the perceiving mind rather than of the world outside the mind. Without perceivers of a certain sort, there would be no colors. One argument for this was the variation in color experiences between people. For example, some people are color-blind, and to a person with jaundice much of the world takes on a yellow cast. In addition, the same object is perceived as having different colors by the same the person under different conditions: at noon and midnight, for example. Such variations are conspicuous in experiences of beauty as well.

Nevertheless, eighteenth-century philosophers such as Hume and Kant perceived that something important was lost when beauty was treated merely as a subjective state. They saw, for example, that controversies often arise about the beauty of particular things, such as works of art and literature, and that in such controversies, reasons can sometimes be given and will sometimes be found convincing. They saw, as well, that if beauty is completely relative to individual experiencers, it ceases to be a paramount value, or even recognizable as a value at all across persons or societies.

Hume's “Of the Standard of Taste” and Kant's Critique Of Judgment attempt to find ways through what has been termed ‘the antinomy of taste.’ Taste is proverbially subjective: de gustibus non est disputandum (about taste there is no disputing). On the other hand, we do frequently dispute about matters of taste, and some persons are held up as exemplars of good taste or of tastelessness. Some people's tastes appear vulgar or ostentatious, for example. Some people's taste is too exquisitely refined, while that of others is crude, naive, or non-existent. Taste, that is, appears to be both subjective and objective: that is the antinomy.

Both Hume and Kant, as we have seen, begin by acknowledging that taste or the ability to detect or experience beauty is fundamentally subjective, that there is no standard of taste in the sense that the Canon was held to be, that if people did not experience certain kinds of pleasure, there would be no beauty. Both acknowledge that reasons can count, however, and that some tastes are better than others. In different ways, they both treat judgments of beauty neither precisely as purely subjective nor precisely as objective but, as we might put it, as inter-subjective or as having a social and cultural aspect, or as conceptually entailing an inter-subjective claim to validity.

Hume's account focuses on the history and condition of the observer as he or she makes the judgment of taste. Our practices with regard to assessing people's taste entail that judgments of taste that reflect idiosyncratic bias, ignorance, or superficiality are not as good as judgments that reflect wide-ranging acquaintance with various objects of judgment and are unaffected by arbitrary prejudices. “Strong sense, united to delicate sentiment, improved by practice, perfected by comparison, and cleared of all prejudice, can alone entitle critics to this valuable character; and the joint verdict of such, wherever they are to found, is the true standard of taste and beauty” (“Of the Standard of Taste” 1757, 144).

Hume argues further that the verdicts of critics who possess those qualities tend to coincide, and approach unanimity in the long run, which accounts, for example, for the enduring veneration of the works of Homer or Milton. So the test of time, as assessed by the verdicts of the best critics, functions as something analogous to an objective standard. Though judgments of taste remain fundamentally subjective, and though certain contemporary works or objects may appear irremediably controversial, the long-run consensus of people who are in a good position to judge functions analogously to an objective standard and renders such standards unnecessary even if they could be identified. Though we cannot directly find a standard of beauty that sets out the qualities that a thing must possess in order to be beautiful, we can describe the qualities of a good critic or a tasteful person. Then the long-run consensus of such persons is the practical standard of taste and the means of justifying judgments about beauty.

Kant similarly concedes that taste is fundamentally subjective, that every judgment of beauty is based on a personal experience, and that such judgments vary from person to person.

By a principle of taste I mean a principle under the condition of which we could subsume the concept of the object, and thus infer, by means of a syllogism, that the object is beautiful. But that is absolutely impossible. For I must immediately feel the pleasure in the representation of the object, and of that I can be persuaded by no grounds of proof whatever. Although, as Hume says, all critics can reason more plausibly than cooks, yet the same fate awaits them. They cannot expect the determining ground of their judgment [to be derived] from the force of the proofs, but only from the reflection of the subject upon its own proper state of pleasure or pain. (Kant 1790, section 34)

But the claim that something is beautiful has more content merely than that it gives me pleasure. Something might please me for reasons entirely eccentric to myself: I might enjoy a bittersweet experience before a portrait of my grandmother, for example, or the architecture of a house might remind me of where I grew up. “No one cares about that,” says Kant (1790, section 7): no one begrudges me such experiences, but they make no claim to guide or correspond to the experiences of others.

By contrast, the judgment that something is beautiful, Kant argues, is a disinterested judgment. It does not respond to my idiosyncrasies, or at any rate if I am aware that it does, I will no longer take myself to be experiencing the beauty per se of the thing in question. Somewhat as in Hume—whose treatment Kant evidently had in mind—one must be unprejudiced to come to a genuine judgment of taste, and Kant gives that idea a very elaborate interpretation: the judgment must be made independently of the normal range of human desires—economic and sexual desires, for instance, which are examples of our ‘interests’ in this sense. If one is walking through a museum and admiring the paintings because they would be extremely expensive were they to come up for auction, for example, or wondering whether one could steal and fence them, one is not having an experience of the beauty of the paintings at all. One must focus on the form of the mental representation of the object for its own sake, as it is in itself. Kant summarizes this as the thought that insofar as one is having an experience of the beauty of something, one is indifferent to its existence. One takes pleasure, rather, in its sheer representation in one's experience:

Now, when the question is whether something is beautiful, we do not want to know whether anything depends or can depend on the existence of the thing, either for myself or anyone else, but how we judge it by mere observation (intuition or reflection). … We easily see that, in saying it is beautiful, and in showing that I have taste, I am concerned, not with that in which I depend on the existence of the object, but with that which I make out of this representation in myself. Everyone must admit that a judgement about beauty, in which the least interest mingles, is very partial and is not a pure judgement of taste. (Kant 1790, section 2)

One important source of the concept of aesthetic disinterestedness is the Third Earl of Shaftesbury's dialogue The Moralists, where the argument is framed in terms of a natural landscape: if you are looking at a beautiful valley primarily as a valuable real estate opportunity, you are not seeing it for its own sake, and cannot fully experience its beauty. If you are looking at a lovely woman and considering her as a possible sexual conquest, you are not able to experience her beauty in the fullest or purest sense; you are distracted from the form as represented in your experience. And Shaftesbury, too, localizes beauty to the representational capacity of the mind. (Shaftesbury 1738, 222)

For Kant, some beauties are dependent—relative to the sort of thing the object is—and others are free or absolute. A beautiful ox would be an ugly horse, but abstract textile designs, for example, may be beautiful in themselves without a reference group or “concept,” and flowers please whether or not we connect them to their practical purposes or functions in plant reproduction (Kant 1790, section 16). The idea in particular that free beauty is completely separated from practical use and that the experiencer of it is not concerned with the actual existence of the object leads Kant to conclude that absolute or free beauty is found in the form or design of the object, or as Clive Bell put it, in the arrangement of lines and colors (in the case of painting) (Bell 1914). By the time Bell writes in the early twentieth century, however, beauty is out of fashion in the arts, and Bell frames his view not in terms of beauty but in terms of a general formalist conception of aesthetic value.

Since in reaching a genuine judgment of taste one is aware that one is not responding to anything idiosyncratic in oneself, Kant asserts (1790, section 8), one will reach the conclusion that anyone similarly situated should have the same experience: that is, one will presume that there ought to be nothing to distinguish one person's judgment from another's (though in fact there may be). Built conceptually into the judgment of taste is the assertion that anyone similarly situated ought to have the same experience and reach the same judgment. Thus, built into judgments of taste is a ‘universalization’ somewhat analogous to the universalization that Kant associates with ethical judgments. In ethical judgments, however, the universalization is objective: if the judgment is true, then it is objectively the case that everyone ought to act on the maxim according to which one acts. In the case of aesthetic judgments, however, the judgment remains subjective, but necessarily contains the ‘demand’ that everyone should reach the same judgment. The judgment conceptually entails a claim to inter-subjective validity. This accounts for the fact that we do very often argue about judgments of taste, and that we find tastes that are different than our own defective.

The influence of this series of thoughts on philosophical aesthetics has been immense. One might mention related approaches taken by such figures as Schopenhauer, Hanslick, Bullough, and Croce, for example. A somewhat similar though more adamantly subjectivist line is taken by Santayana, who defines beauty as ‘objectified pleasure.’ The judgment of something that it is beautiful responds to the fact that it induces a certain sort of pleasure; but this pleasure is attributed to the object, as though the object itself were having subjective states.

We have now reached our definition of beauty, which, in the terms of our successive analysis and narrowing of the conception, is value positive, intrinsic, and objectified. Or, in less technical language, Beauty is pleasure regarded as the quality of a thing. … Beauty is a value, that is, it is not a perception of a matter of fact or of a relation: it is an emotion, an affection of our volitional and appreciative nature. An object cannot be beautiful if it can give pleasure to nobody: a beauty to which all men were forever indifferent is a contradiction in terms. … Beauty is therefore a positive value that is intrinsic; it is a pleasure. (Santayana 1896, 50–51)

It is much as though one were attributing malice to a balky object or device. The object causes certain frustrations and is then ascribed an agency or a kind of subjective agenda that would account for its causing those effects. Now though Santayana thought the experience of beauty could be profound or could even be the meaning of life, this account appears to make beauty a sort of mistake: one attributes subjective states (indeed, one's own) to a thing which in many instances is not capable of having subjective states.

It is worth saying that Santayana's treatment of the topic in The Sense of Beauty (1896) was the last major account offered in English for some time, possibly because, once beauty has been admitted to be entirely subjective, much less when it is held to rest on a sort of mistake, there seems little more to be said. What stuck from Hume's and Kant's treatments was the subjectivity, not the heroic attempts to temper it. If beauty is a subjective pleasure, it would seem to have no higher status than anything that entertains, amuses, or distracts; it seems odd or ridiculous to regard it as being comparable in importance to truth or justice, for example. And the twentieth century also abandoned beauty as the dominant goal of the arts, again possibly in part because its trivialization in theory led artists to believe that they ought to pursue more real and more serious projects. This decline is explored eloquently in Arthur Danto's book The Abuse of Beauty (2003).

However, there has been a revival of interest in beauty in both art and philosophy in recent years, and several theorists have made new attempts to address the antinomy of taste. To some extent, such approaches echo G.E. Moore's: “To say that a thing is beautiful is to say, not indeed that it is itself good, but that it is a necessary element in something which is: to prove that a thing is truly beautiful is to prove that a whole, to which it bears a particular relation as a part, is truly good” (Moore 1903, 201). One interpretation of this would be that what is fundamentally valuable is the situation in which the object and the person experiencing are both embedded; the value of beauty might include both features of the beautiful object and the pleasures of the experiencer.

Similarly, Crispin Sartwell in his book Six Names of Beauty (2004), attributes beauty neither exclusively to the subject nor to the object, but to the relation between them, and even more widely also to the situation or environment in which they are both embedded. He points out that when we attribute beauty to the night sky, for instance, we do not take ourselves simply to be reporting a state of pleasure in ourselves; we are turned outward toward it; we are celebrating the real world. On the other hand, if there were no perceivers capable of experiencing such things, there would be no beauty. Beauty, rather, emerges in situations in which subject and object are juxtaposed and connected.

Alexander Nehamas, in Only a Promise of Happiness (2007), characterizes beauty as an invitation to further experiences, a way that things invite us in, while also possibly fending us off. The beautiful object invites us to explore and interpret, but it also requires us to explore and interpret: beauty is not to be regarded as an instantaneously apprehensible feature of surface. And Nehamas, like Hume and Kant, though in another register, considers beauty to have an irreducibly social dimension. Beauty is something we share, or something we want to share, and shared experiences of beauty are particularly intense forms of communication. Thus, the experience of beauty is not primarily within the skull of the experiencer, but connects observers and objects such as works of art and literature in communities of appreciation.

Aesthetic judgment, I believe, never commands universal agreement, and neither a beautiful object nor a work of art ever engages a catholic community. Beauty creates smaller societies, no less important or serious because they are partial, and, from the point of view of its members, each one is orthodox—orthodox, however, without thinking of all others as heresies. … What is involved is less a matter of understanding and more a matter of hope, of establishing a community that centers around it—a community, to be sure, whose boundaries are constantly shifting and whose edges are never stable. (Nehamas 2007, 80–81)

Each of the views sketched below has many expressions, some of which may be incompatible with one another. In many or perhaps most of the actual formulations, elements of more than one such account are present. For example, Kant's treatment of beauty in terms of disinterested pleasure has obvious elements of hedonism, while the ecstatic neo-Platonism of Plotinus includes not only the unity of the object, but also the fact that beauty calls out love or adoration. However, it is also worth remarking how divergent or even incompatible with one another many of these views are: for example, some philosophers associate beauty exclusively with use, others precisely with uselessness.

The art historian Heinrich Wölfflin gives a fundamental description of the classical conception of beauty, as embodied in Italian Renaissance painting and architecture:

The central idea of the Italian Renaissance is that of perfect proportion. In the human figure as in the edifice, this epoch strove to achieve the image of perfection at rest within itself. Every form developed to self-existent being, the whole freely co-ordinated: nothing but independently living parts…. In the system of a classic composition, the single parts, however firmly they may be rooted in the whole, maintain a certain independence. It is not the anarchy of primitive art: the part is conditioned by the whole, and yet does not cease to have its own life. For the spectator, that presupposes an articulation, a progress from part to part, which is a very different operation from perception as a whole. (Wölfflin 1932, 9–10, 15)

The classical conception is that beauty consists of an arrangement of integral parts into a coherent whole, according to proportion, harmony, symmetry, and similar notions. This is a primordial Western conception of beauty, and is embodied in classical and neo-classical architecture, sculpture, literature, and music wherever they appear. Aristotle says in the Poetics that “to be beautiful, a living creature, and every whole made up of parts, must … present a certain order in its arrangement of parts” (Aristotle, volume 2, 2322 [1450b34]). And in the Metaphysics: “The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree” (Aristotle, volume 2 1705 [1078a36]). This view, as Aristotle implies, is sometimes boiled down to a mathematical formula, such as the golden section, but it need not be thought of in such strict terms. The conception is exemplified above all in such texts as Euclid's Elements and such works of architecture as the Parthenon, and, again, by the Canon of the sculptor Polykleitos (late fifth/early fourth century BCE).

The Canon was not only a statue deigned to display perfect proportion, but a now-lost treatise on beauty. The physician Galen characterizes the text as specifying, for example, the proportions of “the finger to the finger, and of all the fingers to the metacarpus, and the wrist, and of all these to the forearm, and of the forearm to the arm, in fact of everything to everything…. For having taught us in that treatise all the symmetriae of the body, Polyclitus supported his treatise with a work, having made the statue of a man according to his treatise, and having called the statue itself, like the treatise, the Canon” (quoted in Pollitt 1974, 15). It is important to note that the concept of ‘symmetry’ in classical texts is distinct from and richer than its current use to indicate bilateral mirroring. It also refers precisely to the sorts of harmonious and measurable proportions among the parts characteristic of objects that are beautiful in the classical sense, which carried also a moral weight. For example, in the Sophist (228c-e), Plato describes virtuous souls as symmetrical.

The ancient Roman architect Vitruvius gives as good a characterization of the classical conception as any, both in its complexities and, appropriately enough, in its underlying unity:

Architecture consists of Order, which in Greek is called taxis, and arrangement, which the Greeks name diathesis, and of Proportion and Symmetry and Decor and Distribution which in the Greeks is called oeconomia. Order is the balanced adjustment of the details of the work separately, and as to the whole, the arrangement of the proportion with a view to a symmetrical result. Proportion implies a graceful semblance: the suitable display of details in their context. This is attained when the details of the work are of a height suitable to their breadth, of a breadth suitable to their length; in a word, when everything has a symmetrical correspondence. Symmetry also is the appropriate harmony arising out of the details of the work itself: the correspondence of each given detail to the form of the design as a whole. As in the human body, from cubit, foot, palm, inch and other small parts come the symmetric quality of eurhythmy. (Vitruvius, 26–27)

Aquinas, in a typically Aristotelian pluralist formulation, says that “There are three requirements for beauty. Firstly, integrity or perfection—for if something is impaired it is ugly. Then there is due proportion or consonance. And also clarity: whence things that are brightly coloured are called beautiful” (Summa Theologica I, 39, 8).

Francis Hutcheson in the eighteenth century gives what may well be the clearest expression of the view: “What we call Beautiful in Objects, to speak in the Mathematical Style, seems to be in a compound Ratio of Uniformity and Variety; so that where the Uniformity of Bodys is equal, the Beauty is as the Variety; and where the Variety is equal, the Beauty is as the Uniformity” (Hutcheson 1725, 29). Indeed, proponents of the view often speak “in the Mathematical Style.” Hutcheson goes on to adduce mathematical formulae, and specifically the propositions of Euclid, as the most beautiful objects (in another echo of Aristotle), though he also rapturously praises nature, with its massive complexity underlain by universal physical laws as revealed, for example, by Newton. There is beauty, he says, “In the Knowledge of some great Principles, or universal Forces, from which innumerable Effects do flow. Such is Gravitation, in Sir Isaac Newton's Scheme” (Hutcheson 1725, 38).

A very compelling series of refutations of and counter-examples to the idea that beauty can be a matter of any specific proportions between parts, and hence to the classical conception, is given by Edmund Burke in A Philosophical Enquiry into the Origin of our Ideas of the Beautiful and the Sublime:

Turning our eyes to the vegetable kingdom, we find nothing there so beautiful as flowers; but flowers are of every sort of shape, and every sort of disposition; they are turned and fashioned into an infinite variety of forms. … The rose is a large flower, yet it grows upon a small shrub; the flower of the apple is very small, and it grows upon a large tree; yet the rose and the apple blossom are both beautiful. … The swan, confessedly a beautiful bird, has a neck longer than the rest of its body, and but a very short tail; is this a beautiful proportion? we must allow that it is. But what shall we say of the peacock, who has comparatively but a short neck, with a tail longer than the neck and the rest of the body taken together? … There are some parts of the human body, that are observed to hold certain proportions to each other; but before it can be proved, that the efficient cause of beauty lies in these, it must be shewn, that wherever these are found exact, the person to whom they belong is beautiful. … For my part, I have at several times very carefully examined many of these proportions, and found them to hold very nearly, or altogether alike in many subjects, which were not only very different from one another, but where one has been very beautiful, and the other very remote from beauty. … You may assign any proportions you please to every part of the of the human body; and I undertake, that a painter shall observe them all, and notwithstanding produce, if he pleases, a very ugly figure. (Burke 1757, 84–89)

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 1.6])

And 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 1.3]). 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 what makes even the maker of such things as us (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 the tripartite dialectical structure of the view—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.

Both Hegel and Shaftesbury, who associate beauty and art with mind and spirit, hold 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).

Edmund Burke, expressing an ancient tradition, writes that, “by beauty I mean, that quality or those qualities in bodies, by which they cause love, or some passion similar to it” (Burke 1757, 83). As we have seen, in almost all treatments of beauty, even the most apparently object or objectively-oriented, there is a moment in which the subjective qualities of the experience of beauty are emphasized: rhapsodically, perhaps, or in terms of pleasure or ataraxia, as in Schopenhauer. For example, we have already seen Plotinus, for whom beauty is certainly not subjective, describe the experience of beauty ecstatically. In the idealist tradition, the human soul, as it were, recognizes in beauty its true origin and destiny. Among the Greeks, the connection of beauty with love is proverbial from early myth, and Aphrodite the goddess of love won the Judgment of Paris by promising Paris the most beautiful woman in the world.

There is an historical connection between idealist accounts of beauty and those that connect it to love and longing, though there would seem to be no entailment either way. We have Sappho's famous fragment 16: “Some say thronging cavalry, some say foot soldiers, others call a fleet the most beautiful sights the dark world offers, but I say it's whatever you love best” (Sappho, 16). (Indeed, at Phaedrus 236c, Socrates appears to defer to “the fair Sappho” as having had greater insight than himself on love [Plato, 483].)

Plato's discussions of beauty in the Symposium and the Phaedrus occur in the context of the theme of erotic love. In the former, love is portrayed as the ‘child’ of poverty and plenty. “Nor is he delicate and lovely as most of us believe, but harsh and arid, barefoot and homeless” (Plato, 556 [Symposium 203b–d]). Love is portrayed as a lack or absence that seeks its own fulfillment in beauty: a picture of mortality as an infinite longing. Love is always in a state of lack and hence of desire: the desire to possess the beautiful. Then if this state of infinite longing could be trained on the truth, we would have a path to wisdom. The basic idea has been recovered many times, for example by the Romantics. It fueled the cult of idealized or courtly love through the Middle Ages, in which the beloved became a symbol of the infinite.

Recent work on the theory of beauty has revived this idea, and turning away from pleasure has turned toward love or longing (which are not necessarily entirely pleasurable experiences) as the experiential correlate of beauty. Both Sartwell and Nehamas use Sappho's fragment 16 as an epigraph. Sartwell defines beauty as “the object of longing” and characterizes longing as intense and unfulfilled desire. He calls it a fundamental condition of a finite being in time, where we are always in the process of losing whatever we have, and are thus irremediably in a state of longing. And Nehamas writes

I think of beauty as the emblem of what we lack, the mark of an art that speaks to our desire. … Beautiful things don't stand aloof, but direct our attention and our desire to everything else we must learn or acquire in order to understand and possess, and they quicken the sense of life, giving it new shape and direction. (Nehamas 2007, 77)

Thinkers of the 18th century—many of them oriented toward empiricism—accounted for beauty in terms of pleasure. The Italian historian Ludovico Antonio Muratori, for example, in quite a typical formulation, says that “By beautiful we generally understand whatever, when seen, heard, or understood, delights, pleases, and ravishes us by causing within us agreeable sensations” (see Carritt 1931, 60). In Hutcheson it is not clear whether we ought to conceive beauty primarily in terms of classical formal elements or in terms of the viewer's pleasurable response. He begins the Inquiry Into the Original of Our Ideas of Beauty and Virtue with a discussion of pleasure. And he appears to assert that objects which instantiate his “compound ratio of uniformity and variety’ are peculiarly or necessarily capable of producing pleasure:

The only Pleasure of sense, which our Philosophers seem to consider, is that which accompanys the simple Ideas of Sensation; But there are vastly greater Pleasures in those complex Ideas of objects, which obtain the Names of Beautiful, Regular, Harmonious. Thus every one acknowledges he is more delighted with a fine Face, a just Picture, than with the View of any one Colour, were it as strong and lively as possible; and more pleased with a Prospect of the Sun arising among settled Clouds, and colouring their Edges, with a starry Hemisphere, a fine Landskip, a regular Building, than with a clear blue Sky, a smooth Sea, or a large open Plain, not diversify'd by Woods, Hills, Waters, Buildings: And yet even these latter Appearances are not quite simple. So in Musick, the Pleasure of fine Composition is incomparably greater than that of any one Note, how sweet, full, or swelling soever. (Hutcheson 1725, 22)

When Hutcheson then goes on to describe ‘original or absolute beauty,’ he does it, as we have seen, in terms of the qualities of the beautiful thing, and yet throughout, he insists that beauty is centered in the human experience of pleasure. But of course the idea of pleasure could come apart from Hutcheson's particular aesthetic preferences, which are poised precisely opposite Plotinus's, for example. That we find pleasure in a symmetrical rather than an asymmetrical building (if we do) is contingent. But that beauty is connected to pleasure appears, according to Hutcheson, to be necessary, and the pleasure which is the locus of beauty itself has ideas rather than things as its object.

Hume writes in a similar vein in the Treatise of Human Nature:

Beauty is such an order and construction of parts as, either by the primary constitution of our nature, by custom, or by caprice, is fitted to give a pleasure and satisfaction to the soul. … Pleasure and pain, therefore, are not only necessary attendants of beauty and deformity, but constitute their very essence. (Hume 1740, 299)

Though this appears ambiguous as between locating the beauty in the pleasure or in the impression or idea that causes it, Hume is soon talking about the ‘sentiment of beauty,’ where sentiment is, roughly, a pleasurable or painful response to impressions or ideas, though beauty is a matter of cultivated or delicate pleasures. Indeed, by the time of Kant's Third Critique and after that for perhaps two centuries, the direct connection of beauty to pleasure is taken as a commonplace, to the point where thinkers are frequently identifying beauty as a certain sort of pleasure. Santayana, for example, as we have seen, while still gesturing in the direction of the object or experience that causes pleasure, emphatically identifies beauty as a certain sort of pleasure.

One result of this approach to beauty—or perhaps an extreme expression of this orientation—is the assertion of the positivists that words such as ‘beauty’ are meaningless or without cognitive content, or are mere expressions of subjective approval. Hume and Kant were no sooner declaring beauty to be a matter of sentiment or pleasure and therefore to be subjective than they were trying to ameliorate the sting, largely by emphasizing critical consensus. But once this fundamental admission is made, any consensus is contingent. Another way to formulate this is that it appears to certain thinkers after Hume and Kant that there can be no reasons to prefer the consensus to a counter-consensus assessment. A.J. Ayer writes:

Such aesthetic words as ‘beautiful’ and ‘hideous’ are employed … not to make statements of fact, but simply to express certain feelings and evoke a certain response. It follows…that there is no sense attributing objective validity to aesthetic judgments, and no possibility of arguing about questions of value in aesthetics. (Ayer 1952, 113)

All meaningful claims either concern the meaning of terms or are empirical, in which case they are meaningful because observations could confirm or disconfirm them. ‘That song is beautiful’ has neither status, and hence has no empirical or conceptual content. It merely expresses a positive attitude of a particular viewer; it is an expression of pleasure, like a satisfied sigh. The question of beauty is not a genuine question, and we can safely leave it behind or alone. Most twentieth-century philosophers did just that.

Philosophers in the Kantian tradition identify the experience of beauty with disinterested pleasure, psychical distance, and the like, and contrast the aesthetic with the practical. “Taste is the faculty of judging an object or mode of representing it by an entirely disinterested satisfaction or dissatisfaction. The object of such satisfaction is called beautiful” (Kant 1790, 45). Edward Bullough distinguishes the beautiful from the merely agreeable on the grounds that the former requires a distance from practical concerns: “Distance is produced in the first instance by putting the phenomenon, so to speak, out of gear with our practical, actual self; by allowing it to stand outside the context of our personal needs and ends.“ (Bullough 1912, 244)

On the other hand, many philosophers have gone in the opposite direction and have identified beauty with suitedness to use. ‘Beauty’ is perhaps one of the few terms that could plausibly sustain such entirely opposed interpretations.

According to Diogenes Laertius, the ancient hedonist Aristippus of Cyrene took a rather direct approach.

Is not then, also, a beautiful woman useful in proportion as she is beautiful; and a boy and a youth useful in proportion to their beauty? Well then, a handsome boy and a handsome youth must be useful exactly in proportion as they are handsome. Now the use of beauty is, to be embraced. If then a man embraces a woman just as it is useful that he should, he does not do wrong; nor, again, will he be doing wrong in employing beauty for the purposes for which it is useful. (Diogenes Laertius, 94)

In some ways, Aristippus is portrayed parodically: as the very worst of the sophists, though supposedly a follower of Socrates. And yet the idea of beauty as suitedness to use finds expression in a number of thinkers. Xenophon's Memorabilia puts the view in the mouth of Socrates, with Aristippus as interlocutor:

Socrates: In short everything which we use is considered both good and beautiful from the same point of view, namely its use. Aristippus: Why then, is a dung-basket a beautiful thing? Socrates: Of course it is, and a golden shield is ugly, if the one be beautifully fitted to its purpose and the other ill. (Xenophon, Book III, viii)

Berkeley expresses a similar view in his dialogue Alciphron, though he begins with the hedonist conception: “Every one knows that beauty is what pleases” (Berkeley 1732, 174, see Carritt 1931, 75). But it pleases for reasons of usefulness. Thus, as Xenophon suggests, on this view, things are beautiful only in relation to the uses for which they are intended or to which they are properly applied. The proper proportions of an object depend on what kind of object it is, and again a beautiful ox would make an ugly horse. “The parts, therefore, in true proportions, must be so related, and adjusted to one another, as they may best conspire to the use and operation of the whole” (Berkeley 1732, 174–75, see Carritt 1931, 76). One result of this is that, though beauty remains tied to pleasure, it is not an immediate sensible experience. It essentially requires intellection and practical activity: one has to know the use of a thing, and assess its suitedness to that use.

This treatment of beauty is often used, for example, to criticize the distinction between fine art and craft, and it avoids sheer philistinism by enriching the concept of ‘use,’ so that it might encompass not only performing a practical task, but performing it especially well or with an especial satisfaction. Ananda Coomaraswamy, the Ceylonese-British scholar of Indian and European medieval arts, adds that a beautiful work of art or craft expresses as well as serves its purpose.

A cathedral is not as such more beautiful than an airplane, … a hymn than a mathematical equation. … A well-made sword is not more beautiful than a well-made scalpel, though one is used to slay, the other to heal. Works of art are only good or bad, beautiful or ugly in themselves, to the extent that they are or are not well and truly made, that is, do or do not express, or do or do not serve their purpose. (Coomaraswamy 1977, 75)

Roger Scruton, in his book Beauty (2009) returns to a modified Kantianism with regard to both beauty and sublimity, enriched by many and varied examples. "We call something beautiful," writes Scruton, "when we gain pleasure from contemplating it as an individual object, for its own sake, and in its presented form." (Scruton 2009, 26)

Despite the Kantian framework, Scruton, like Sartwell and Nehamas, throws the subjective/objective distinction into question. He compares experiencing a beautiful thing to a kiss. To kiss someone that one loves is not merely to place one body part on another, "but to touch the other person in his very self. Hence the kiss is compromising - it is a move from one self toward another, and a summoning of the other into the surface of his being." (Scruton 2009, 48)
