In aesthetics, "unity in variety" (sometimes "unity in diversity" [1] ) is a principle declaring that in art beauty can come from the variety of diverse components grouped together thus creating a fused impression as a whole. [2] In the more broad meaning, to find pleasure in interaction with any set of objects, humans need to perceive order among the parts of the set. [3] Human brain is wired to see the connections, so finding such groups (based on elements being close together or having similar looks, sounds, or textures [4] ) feels aesthetically pleasing. [5]
Paul Hekkert offers a multi-course meal as an example: a pleasing meal might have a variety of tastes between different courses, yet the unity is provided by the (common) consistency of tastes within each course. [5]
The interdisciplinary concept of unity in variety is studied in psychology (principles of grouping constitute part of the Gestalt theory [4] ), philosophy, visual arts, music, information theory. [3]
Unity and variety, as partial opposites, are both contributing to the aesthetic pleasure. Variety characterizes the quantity and scale of perceived differences encountered. [3] Humans seek the variety (that carries a promise of learning) to avoid the state of boredom, yet too much variety is perceived as chaos. Human brain needs the generally chaotic world to be structured for a better apperception, perceptual organization, and processing fluency, thus creating the want for unity, a holistic view enabled through perception of order and coherence between the parts of the whole. [6]
In an example provided by Post et al., a car designer might choose to provide the variety through the use of a different color for the car door handles (contrast) while enforcing unity by placing similarly-shaped handles on a single line that can be visually extended to the headlights ("continuity"). [6]
A human ability to perceive spatial grouping and see a meaningful whole object can be explained from an evolutionary perspective (for example, an ability to reconstruct a partially hidden tiger from the visible pieces is quite advantageous). From the neurophysiological point of view, perceiving unity underlying the collection of disparate objects economizes the capacity of the brain, reducing the allocation of attentional resources. [4]
The principle can be traced to Antiquity (cf. Plotinus, Enneads 1.6 and 5.8.1–2, c. 270 A.D.). [3] [7] Pre-Plotinus the term was not directly related to beauty, unity in diversity was assumed to be a fundamental property of the universe. Plotinus' ideas spread to Western thought during the late 15th century, when his writings were translated by Marsilio Ficino. [1] The concept of unity in variety was further developed in the early 1700s by Francis Hutcheson, who declared that excitement is generated by "Uniformity amidst Variety", which generates a "disinterested" pleasure (i.e., the one with no regard for practical issues, like existence of the considered object or the wants of the body, like thirst). In the late 18th century Kant explained the feeling of beauty by "free play" of the human cognition, unshackled from the minutiae of reality and instead finding pleasure in a search of a unifying structure. [8]
The concept of unity in variety was first applied to the empirical aesthetics in the end of the 19th century by Gustav Fechner as the "principle of unitary connection of the manifold": humans "tolerate most often and for the longest time a certain medium degree of arousal, which makes them feel neither overstimulated nor dissatisfied by a lack of sufficient occupation". [9] Fechner thus started the a tradition of analysis of unity in variety as a hedonistic phenomenon. [10]
In 1971 Daniel Berlyne and W. J. Boudewijns [11] performed experiments studying unity in variety using visual patterns with similarities and differences. Their findings appear to confirm that liking of the images is at the peak when both unity (similarities between the parts) and variety (contrast) are applied. [9] In 1938 Robert S. Woodworth proposed a unity in variety as an explanation of the golden section: square is all unity, narrow rectangle is a lot of variety, the pleasant appearance is somewhere in between (the debate about this idea was still ongoing in the 1990s). [12] The end of the 20th century brought interest in precise definitions of unity and diversity, this purely cognitive analysis breaks with the Fechner's hedonistic approach. Kathleen Moore in 1986 had associated the unity with spatial frequency. [10]
Aesthetics is the branch of philosophy concerned with the nature of beauty and the nature of taste; and functions as the philosophy of art. Aesthetics examines the philosophy of aesthetic value, which is determined by critical judgements of artistic taste; thus, the function of aesthetics is the "critical reflection on art, culture and nature".
Beauty is commonly described as a feature of objects that makes them pleasurable to perceive. Such objects include landscapes, sunsets, humans and works of art. Beauty, art and taste are the main subjects of aesthetics, one of the major branches of philosophy. As a positive aesthetic value, it is contrasted with ugliness as its negative counterpart.
Hedonism refers to the prioritization of pleasure in one's lifestyle, actions, or thoughts. The term can include a number of theories or practices across philosophy, art, and psychology, encompassing both sensory pleasure and more intellectual or personal pursuits, but can also be used in everyday parlance as a pejorative for the egoistic pursuit of short-term gratification at the expense of others.
Pleasure is experience that feels good, that involves the enjoyment of something. It contrasts with pain or suffering, which are forms of feeling bad. It is closely related to value, desire and action: humans and other conscious animals find pleasure enjoyable, positive or worthy of seeking. A great variety of activities may be experienced as pleasurable, like eating, having sex, listening to music or playing games. Pleasure is part of various other mental states such as ecstasy, euphoria and flow. Happiness and well-being are closely related to pleasure but not identical with it. There is no general agreement as to whether pleasure should be understood as a sensation, a quality of experiences, an attitude to experiences or otherwise. Pleasure plays a central role in the family of philosophical theories known as hedonism.
Gustav Theodor Fechner was a German physicist, philosopher, and experimental psychologist. A pioneer in experimental psychology and founder of psychophysics, he inspired many 20th-century scientists and philosophers. He is also credited with demonstrating the non-linear relationship between psychological sensation and the physical intensity of a stimulus via the formula: , which became known as the Weber–Fechner law.
In aesthetics, the sublime is the quality of greatness, whether physical, moral, intellectual, metaphysical, aesthetic, spiritual, or artistic. The term especially refers to a greatness beyond all possibility of calculation, measurement, or imitation.
Neuroesthetics is a relatively recent sub-discipline of applied aesthetics. Empirical aesthetics takes a scientific approach to the study of aesthetic experience of art, music, or any object that can give rise to aesthetic judgments. Neuroesthetics is a term coined by Semir Zeki in 1999 and received its formal definition in 2002 as the scientific study of the neural bases for the contemplation and creation of a work of art. Anthropologists and evolutionary biologists alike have accumulated evidence suggesting that human interest in, and creation of, art evolved as an evolutionarily necessary mechanism for survival as early as the 9th and 10th century in Gregorian monks and Native Americans. Neuroesthetics uses neuroscience to explain and understand the aesthetic experiences at the neurological level. The topic attracts scholars from many disciplines including neuroscientists, art historians, artists, art therapists and psychologists.
Curiosity is a quality related to inquisitive thinking such as exploration, investigation, and learning, evident in humans and animals. Curiosity helps human development, from which derives the process of learning and desire to acquire knowledge and skill.
This is a history of aesthetics.
The psychology of art is the scientific study of cognitive and emotional processes precipitated by the sensory perception of aesthetic artefacts, such as viewing a painting or touching a sculpture. It is an emerging multidisciplinary field of inquiry, closely related to the psychology of aesthetics, including neuroaesthetics.
Applied aesthetics is the application of the branch of philosophy of aesthetics to cultural constructs. In a variety of fields, artifacts are created that have both practical functionality and aesthetic affectation. In some cases, aesthetics is primary, and in others, functionality is primary. At best, the two needs are synergistic, in which "beauty" makes an artifact work better, or in which more functional artifacts are appreciated as aesthetically pleasing. This achievement of form and function, of art and science, of beauty and usefulness, is the primary goal of design, in all of its domains.
The International Association of Empirical Aesthetics (IAEA) is a psychological organization founded to scientifically investigate the nature of aesthetic experience and aesthetic behavior. The group has members in over 25 countries. IAEA was founded at the first international congress in Paris in 1965 by Daniel Berlyne, Robert Francés, Carmelo Genovese, and Albert Wellek.
The processing fluency theory of aesthetic pleasure is a theory in psychological aesthetics on how people experience beauty. Processing fluency is the ease with which information is processed in the human mind.
Rolf Reber is professor of psychology at the University of Oslo.
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.
The Sense of Beauty is a book on aesthetics by the philosopher George Santayana. The book was published in 1896 by Charles Scribner's Sons, and is based on the lectures Santayana gave on aesthetics while teaching at Harvard University. Santayana published the book out of necessity, for tenure, rather than inspiration. In an anecdote retold by art critic Arthur Danto of a meeting with Santayana in 1950, Santayana was reported to have said that "they let me know through the ladies that I had better publish a book... on art, of course. So I wrote this wretched potboiler."
In psychology of art, the relationship between art and emotion has newly been the subject of extensive study thanks to the intervention of esteemed art historian Alexander Nemerov. Emotional or aesthetic responses to art have previously been viewed as basic stimulus response, but new theories and research have suggested that these experiences are more complex and able to be studied experimentally. Emotional responses are often regarded as the keystone to experiencing art, and the creation of an emotional experience has been argued as the purpose of artistic expression. Research has shown that the neurological underpinnings of perceiving art differ from those used in standard object recognition. Instead, brain regions involved in the experience of emotion and goal setting show activation when viewing art.
Experimental aesthetics is a field of psychology founded by Gustav Theodor Fechner in the 19th century. According to Fechner, aesthetics is an experiential perception which is empirically comprehensible in light of the characteristics of the subject undergoing the experience and those of the object. Experimental aesthetics is the second oldest research area in psychology, psychophysics being the only field which is older. In his central work Introduction to Aesthetics Fechner describes his empirical approach extensively and in detail. Experimental aesthetics is characterized by a subject-based, inductive approach.
Helmut Leder is a Professor of Empirical Aesthetics in Psychology at the Faculty of Psychology of the University of Vienna, in Austria and he is the Head of the Cognitive Sciences Research Hub. He received his Degree Diploma in Psychology in 1990 from the RWTH Aachen University, with a minor in art history, and his Ph.D. in Psychology in 1996 from University of Fribourg and a habilitation from FU Berlin in 2001. His research within the field of experimental aesthetics has aimed to clarify the psychological processes involved in the appreciation of art and aesthetics. From 2014 until 2018, he was the president of the International Association of Empirical Aesthetics.
Medieval aesthetics refers to the general philosophy of beauty during the Medieval period. Although Aesthetics did not exist as a field of study during the Middle Ages, influential thinkers active during the period did discuss the nature of beauty and thus an understanding of medieval aesthetics can be obtained from their writings.
