Computational inference of aesthetics

Computational inference of aesthetics

Since about 2005, computer scientists have attempted to develop automated methods to infer aesthetic quality of images.[48][49][50] Typically, these approaches follow a machine learning approach, where large numbers of manually rated photographs are used to "teach" a computer about what visual properties are of relevance to aesthetic quality. The Acquine engine, developed at Penn State University, rates natural photographs uploaded by users.[51]
Notable in this area is Michael Leyton, professor of psychology at Rutgers University. Leyton is the president of the International Society for Mathematical and Computational Aesthetics and the International Society for Group Theory in Cognitive Science and has developed a generative theory of shape.
There have also been relatively successful attempts with regard to chess and music

Aesthetic ethics

Aesthetic ethics

Aesthetic ethics refers to the idea that human conduct and behaviour ought to be governed by that which is beautiful and attractive. John Dewey[43] has pointed out that the unity of aesthetics and ethics is in fact reflected in our understanding of behaviour being "fair" - the word having a double meaning of attractive and morally acceptable. More recently, James Page[44] has suggested that aesthetic ethics might be taken to form a philosophical rationale for peace education

Aesthetics and information

Aesthetics and information


In the 1970s, Abraham Moles and Frieder Nake were among the first to analyze links between aesthetics, information processing, and information theory.[29][30]
In the 1990s, Jürgen Schmidhuber described an algorithmic theory of beauty which takes the subjectivity of the observer into account and postulates: among several observations classified as comparable by a given subjective observer, the aesthetically most pleasing one is the one with the shortest description, given the observer’s previous knowledge and his particular method for encoding the data.[31][32] This is closely related to the principles of algorithmic information theory and minimum description length. One of his examples: mathematicians enjoy simple proofs with a short description in their formal language. Another very concrete example describes an aesthetically pleasing human face whose proportions can be described by very few bits of information,[33][34] drawing inspiration from less detailed 15th century proportion studies by Leonardo da Vinci and Albrecht Dürer. Schmidhuber's theory explicitly distinguishes between what's beautiful and what's interesting, stating that interestingness corresponds to the first derivative of subjectively perceived beauty. Here the premise is that any observer continually tries to improve the predictability and compressibility of the observations by discovering regularities such as repetitions and symmetries and fractal self-similarity. Whenever the observer's learning process (which may be a predictive neural network - see also Neuroesthetics) leads to improved data compression such that the observation sequence can be described by fewer bits than before, the temporary interestingness of the data corresponds to the number of saved bits. This compression progress is proportional to the observer's internal reward, also called curiosity reward. A reinforcement learning algorithm is used to maximize future expected reward by learning to execute action sequences that cause additional interesting input data with yet unknown but learnable predictability or regularity. The principles can be implemented on artificial agents which then exhibit a form of artificial curiosity.

Evolutionary aesthetics

Evolutionary aesthetics

Evolutionary aesthetics refers to evolutionary psychology theories in which the basic aesthetic preferences of Homo sapiens are argued to have evolved in order to enhance survival and reproductive success. One example being that humans are argued to find beautiful and prefer landscapes which were good habitats in the ancestral environment. Another example is that body symmetry is an important aspect of physical attractiveness which may be due to this indicating good health during body growth. Evolutionary explanations for aesthetical preferences are important parts of evolutionary musicology, Darwinian literary studies, and the study of the evolution of emotion

Post-modern aesthetics and psychoanalysis

Post-modern aesthetics and psychoanalysis

Early-twentieth-century artists, poets and composers challenged existing notions of beauty, broadening the scope of art and aesthetics. In 1941, Eli Siegel, American philosopher and poet, founded Aesthetic Realism, the philosophy that reality itself is aesthetic, and that "The world, art, and self explain each other: each is the aesthetic oneness of opposites."[14][15]
Various attempts have been made to define Post-modern aesthetics. The challenge to the assumption that beauty was central to art and aesthetics, thought to be original, is actually continuous with older aesthetic theory; Aristotle was the first in the Western tradition to classify "beauty" into types as in his theory of drama, and Kant made a distinction between beauty and the sublime. What was new was a refusal to credit the higher status of certain types, where the taxonomy implied a preference for tragedy and the sublime to comedy and the Rococo.
Croce suggested that “expression” is central in the way that beauty was once thought to be central. George Dickie suggested that the sociological institutions of the art world were the glue binding art and sensibility into unities.[16] Marshall McLuhan suggested that art always functions as a "counter-environment" designed to make visible what is usually invisible about a society.[page needed] Theodor Adorno felt that aesthetics could not proceed without confronting the role of the culture industry in the commodification of art and aesthetic experience. Hal Foster attempted to portray the reaction against beauty and Modernist art in The Anti-Aesthetic: Essays on Postmodern Culture. Arthur Danto has described this reaction as "kalliphobia" (after the Greek word for beauty - 'kalos').[17] André Malraux explains that the notion of beauty was connected to a particular conception of art that arose with the Renaissance and was still dominant in the eighteenth century (but was supplanted later). The discipline of aesthetics, which originated in the eighteenth century, mistook this transient state of affairs for a revelation of the permanent nature of art.[18] Brian Massumi suggests to reconsider beauty following the aesthetical thought in the philosophy of Deleuze and Guattari.[19]
Daniel Berlyne created the field of experimental aesthetics in the 1970s, for which he is still the most cited individual decades after his death.[20]
Pneumaist aestheticism is a theory of art and a highly experimental approach to art negating historical preconceptions of the aesthetic.
Jean-François Lyotard re-invokes the Kantian distinction between taste and the sublime. Sublime painting, unlike kitsch realism, "...will enable us to see only by making it impossible to see; it will please only by causing pain."[21][22]
Sigmund Freud inaugurated aesthetical thinking in Psychoanalysis mainly via the "Uncanny" as aesthetical affect.[23] Following Freud and Merleau-Ponty,[24] Jacques Lacan theorized aesthetics in terms of sublimation and the Thing[25]
Guy Sircello pioneered efforts in analytic philosophy to develop a rigorous theory of aesthetics, focusing on the concepts of beauty,[26] love[27] and sublimity.[28] In contrast to romantic theorists Sircello argued for the objectivity of beauty and formulated a theory of love on that basis.

Modern aesthetics

Modern aesthetics

From the late 17th to the early 20th century Western aesthetics underwent a slow revolution into what is often called modernism. German and British thinkers emphasised beauty as the key component of art and of the aesthetic experience, and saw art as necessarily aiming at absolute beauty.
For Alexander Gottlieb Baumgarten aesthetics is the science of the sense experiences, a younger sister of logic, and beauty is thus the most perfect kind of knowledge that sense experience can have. For Immanuel Kant the aesthetic experience of beauty is a judgment of a subjective but similar human truth, since all people should agree that “this rose is beautiful” if it in fact is. However, beauty cannot be reduced to any more basic set of features. For Friedrich Schiller aesthetic appreciation of beauty is the most perfect reconciliation of the sensual and rational parts of human nature.
For Friedrich Wilhelm Joseph Schelling, the philosophy of art is the "organon" of philosophy concerning the relation between man and nature. So aesthetics began now to be the name for the philosophy of art. Friedrich von Schlegel, August Wilhelm Schlegel, Friedrich Schleiermacher and Georg Wilhelm Friedrich Hegel have also given lectures on aesthetics as philosophy of art after 1800.
For Hegel all culture is a matter of "absolute spirit" coming to be manifest to itself, stage by stage, changing to a perfection that only philosophy can approach. Art is the first stage in which the absolute spirit is manifest immediately to sense-perception, and is thus an objective rather than subjective revelation of beauty.
For Arthur Schopenhauer aesthetic contemplation of beauty is the most free that the pure intellect can be from the dictates of will; here we contemplate perfection of form without any kind of worldly agenda, and thus any intrusion of utility or politics would ruin the point of the beauty. It is thus for Schopenhauer one way to fight the suffering.
The British were largely divided into intuitionist and analytic camps. The intuitionists believed that aesthetic experience was disclosed by a single mental faculty of some kind. For Anthony Ashley-Cooper, 3rd Earl of Shaftesbury this was identical to the moral sense, beauty just is the sensory version of moral goodness. For Ludwig Wittgenstein aesthetics consisted in the description of a whole culture which is a linguistic impossibility. That which constitutes aesthetics lies out side the realm of the language game.
For Oscar Wilde the contemplation of beauty for beauty's sake was not only the foundation for much of his literary career but was quoted as saying "Aestheticism is a search after the signs of the beautiful. It is the science of the beautiful through which men seek the correlation of the arts. It is, to speak more exactly, the search after the secret of life.".[12]
Wilde famously toured the United States in 1882. He travelled across the United States spreading the idea of Aesthetics in a speech called "The English Renaissance." In his speech he proposed that Beauty and Aesthetics was "not languid but energetic. By beautifying the outward aspects of life, one would beautify the inner ones." The English Renaissance was, he said, "like the Italian Renaissance before it, a sort of rebirth of the spirit of man

Western medieval aesthetics

Western medieval aesthetics

Surviving medieval art is primarily religious in focus and funded largely by the State, Roman Catholic or Orthodox church, powerful ecclesiastical individuals, or wealthy secular patrons. These art pieces often served a liturgical function, whether as chalices or even as church buildings themselves. Objects of fine art from this period were frequently made from rare and valuable materials, such as gold and lapis, the cost of which commonly exceeded the wages of the artist.
Medieval aesthetics in the realm of philosophy built upon Classical thought, continuing the practice of Plotinus by employing theological terminology in its explications. St. Bonaventure’s “Retracing the Arts to Theology”, a primary example of this method, discusses the skills of the artisan as gifts given by God for the purpose of disclosing God to mankind, which purpose is achieved through four lights: the light of skill in mechanical arts which discloses the world of artifacts; which light is guided by the light of sense perception which discloses the world of natural forms; which light, consequently, is guided by the light of philosophy which discloses the world of intellectual truth; finally, this light is guided by the light of divine wisdom which discloses the world of saving truth.
Saint Thomas Aquinas's aesthetic is probably the most famous and influential theory among medieval authors, having been the subject of much scrutiny in the wake of the neo-Scholastic revival of the late 19th and early 20th centuries and even having received the approbation of the celebrated Modernist writer, James Joyce. Thomas, like many other medievals, never gives a systematic account of beauty itself, but several scholars have conventionally arranged his thought—though not always with uniform conclusions—using relevant observations spanning the entire corpus of his work. While Aquinas's theory follows generally the model of Aristotle, he develops a singular aesthetics which incorporates elements unique to his thought. Umberto Eco's The Aesthetics of Thomas Aquinas identifies the three main characteristics of beauty in Aquinas's philosophy: integritas sive perfectio, consonantia sive debita proportio, and claritas sive splendor formae. While Aristotle likewise identifies the first two characteristics, St. Thomas conceives of the third as an appropriation from principles developed by neo-Platonic and Augustinian thinkers.

With the shift from the Middle Ages to the Renaissance, art likewise changed its focus, as much in its content as in its mode of expression.
