AESTHETICSTHE DEVELOPMENT OF WESTERN AESTHETICS

The contributions of the ancient Greeks The two greatest Greek philosophers, Plato and Aristotle, shared a sense of the importance of aesthetics, and both regarded music, poetry, architecture, and drama as fundamental institutions within the body politic. Plato notoriously recommends the banning of poets and painters from his ideal republic and in the course of his argument provides an extended theory of imitation (mimesis), along with spurious reasons for thinking that imitation derogates both from the laws of morality and from the rational cognition of the world. Much of Aristotle's extended and diverse reply to Plato is concerned with rehabilitating imitation as the foundation of moral education (Ethica Nicomachea), as the origin of a necessary katharsis (Poetica), and as the instrument-through music, dance, and poetry-of character formation (Politica). Plato's more mystical writings, notably the Timaeus, contain hints of another approach to aesthetics, one based on the Pythagorean theory of the cosmos that exerted a decisive influence on the Neoplatonists. Through the writings of St. Augustine, Boethius, and Macrobius, the Pythagorean cosmology and its associated aesthetic of harmony were passed on to the thinkers of the Middle Ages. The Aristotelian theory of imitation and the concern with the expressive and emotionally educative aspect of aesthetic experience were not truly influential until the 17th century. At that time much attention was also paid to another classical work, the Hellenistic treatise on the sublime ascribed to Longinus, which is perhaps the most interesting and extended piece of antique literary criticism to have been passed on to the modern world. Medieval aesthetics St. Thomas Aquinas devoted certain passages of his Summa Theologiae (c. 1266-73) to the study of beauty. To his thinking, man's interest in beauty is of sensuous origin, but it is the prerogative of those senses that are capable of "contemplation"-namely, the eye and the ear. Aquinas defines beauty in Aristotelian terms as that which pleases solely in the contemplation of it and recognizes three prerequisites of beauty: perfection, appropriate proportion, and clarity. Aquinas' position typifies the approach to aesthetics adopted by the Scholastics. More widely diffused among medieval thinkers was the Neoplatonist theory, in which beauty is seen as a kind of divine order conforming to mathematical laws: the laws of number, which are also the laws of harmony. Music, poetry, and architecture all exhibit the same conformity to a cosmic order, and, in experiencing their beauty, we are really experiencing the same order in ourselves and resonating to it as one string to another. This theory, expounded in treatises on music by St. Augustine and Boethius, is consciously invoked by Dante in his Convivio (c. 1304-07; The Banquet). In this piece, generally considered one of the first sustained works of literary criticism in the modern manner, the poet analyzes the four levels of meaning contained in his own poems. The Neoplatonist emphasis on number and harmony dominated aesthetics during the early Renaissance as well and was reaffirmed by Leon Alberti in his great treatise on architecture, De Re Aedificatoria (1452; Ten Books on Architecture). Alberti also advanced a definition of beauty, which he called concinnitas, taking his terminology from Cicero. Beauty is for Alberti such an order and arrangement of the parts of an object that nothing can be altered except for the worse. This kind of definition can hardly stand alone as a basis for aesthetics, for what does the word worse mean? The obvious answer, "less beautiful," at once reduces the definition to circularity. The work of art As the above discussion illustrates, it is impossible to advance far into the theory of aesthetic experience without encountering the specific problems posed by the experience of art. Whether or not we think of art as the central or defining example of the aesthetic object, there is no doubt that it provides the most distinctive illustration both of the elusive nature and the importance of aesthetic interest. With the increasing attention paid to art in a corrupted world where little else is commonly held to be spiritually significant, it is not surprising that the philosophy of art has increasingly begun to displace the philosophy of natural beauty from the central position accorded to the latter by the philosophers and critics of the 18th century. Nor is this shift in emphasis to be regretted; for the existence of art as a major human institution reminds us of the need for a theory that will attribute more to aesthetic experience than enjoyment and that will explain the profundity of the impressions that we receive from beauty-impressions that may provide both meaning and solace to those who experience them. It is thus worth reviewing some of the special problems in the philosophy of art that have most influenced contemporary aesthetics. Understanding art The use of the concept of understanding in describing the appreciation of art marks out an interesting distinction between art and natural beauty. A person may understand or fail to understand T.S. Eliot's Four Quartets, Michelangelo's "David," or Beethoven's Ninth Symphony, but he cannot understand or fail to understand the Highlands of Scotland, even when he finds them beautiful or ugly. Understanding seems to be a prerequisite to the full experience of art, and this has suggested to many critics and philosophers that art is not so much an object of sensory experience as an instrument of knowledge. In particular, art seems to have the power both to represent reality and to express emotion, and some argue that it is through appreciating the properties of representation and expression that we recognize the meaning of art. At least, it might be supposed that, if we speak of understanding art, it is because we think of art as having content, something that must be understood by the appropriate audience. The most popular approach to this concept of understanding is through a theory of art as a form of symbolism. But what is meant by this? Is such symbolism one thing or many? Is it a matter of evocation or convention, of personal response or linguistic rule? And what does art symbolize-ideas, feelings, objects, or states of affairs?
