Aesthetics (also spelled ? sthetics or esthetics) is commonly known as the study of sensory or sensori-emotional values, sometimes called judgments of sentiment and taste.  More broadly, scholars in the field define aesthetics as “critical reflection on art, culture and nature. “ Aesthetics is a subdiscipline of axiology, a branch of philosophy, and is closely associated with the philosophy of art.  Aesthetics studies new ways of seeing and of perceiving the world.  *
Etymology The term esthetics 1790-, derives from the German asthetisch (Alexander Baumgarten, c. 1750) or the French esthetique, both derived from the Greek ?????????? (aisthetikos) “esthetic-sensitive-sentient”, from ??????? – Aesthetic judgment Judgments of aesthetic value clearly rely on our ability to discriminate at a sensory level. Aesthetics examines our affective domain response to an object or phenomenon. Immanuel Kant, writing in 1790, observes of a man “If he says that canary wine is agreeable he is quite content if someone else corrects his terms and reminds him to say instead: It is agreeable to me,” because “Everyone has his own (sense of) taste”.
The case of “beauty” is different from mere “agreeableness” because, “If he proclaims something to be beautiful, then he requires the same liking from others; he then judges not just for himself but for everyone, and speaks of beauty as if it were a property of things. ” Aesthetic judgments usually go beyond sensory discrimination. For David Hume, delicacy of taste is not merely “the ability to detect all the ingredients in a composition”, but also our sensitivity “to pains as well as pleasures, which escape the rest of mankind.
” (Essays Moral Political and Literary. Indianapolis, Literary Classics 5, 1987. ) Thus, the sensory discrimination is linked to capacity for pleasure. For Kant “enjoyment” is the result when pleasure arises from sensation, but judging something to be “beautiful” has a third requirement: sensation must give rise to pleasure by engaging our capacities of reflective contemplation. Judgments of beauty are sensory, emotional and intellectual all at once. Viewer interpretations of beauty possess two concepts of value:
Aesthetics and taste. Aesthetics is the philosophical notion of beauty. Taste is a result of education and awareness of elite cultural values; therefore taste can be learned. Taste varies according to class, cultural background, and education. According to Kant, beauty is objective and universal; thus certain things are beautiful to everyone. The contemporary view of beauty is not based on innate qualities, but rather on cultural specifics and individual interpretations. What factors are involved in an aesthetic judgment?
Judgments of aesthetic value seem often to involve many other kinds of issues as well. Responses such as disgust show that sensory detection is linked in instinctual ways to facial expressions, and even behaviors like the gag reflex. Yet disgust can often be a learned or cultural issue too; as Darwin pointed out, seeing a stripe of soup in a man’s beard is disgusting even though neither soup nor beards are themselves disgusting. Aesthetic judgments may be linked to emotions or, like emotions, partially embodied in our physical reactions.
Seeing a sublime view of a landscape may give us a reaction of awe, which might manifest physically as an increased heart rate or widened eyes. These unconscious reactions may even be partly constitutive of what makes our judgment a judgment that the landscape is sublime. Likewise, aesthetic judgments may be culturally conditioned to some extent. Victorians in Britain often saw African sculpture as ugly, but just a few decades later, Edwardian audiences saw the same sculptures as being beautiful. The Abuse of Beauty, Evaluations of beauty may well be linked to desirability, perhaps even to sexual desirability.
Thus, judgments of aesthetic value can become linked to judgments of economic, political, or moral value.  We might judge a Lamborghini to be beautiful partly because it is desirable as a status symbol, or we might judge it to be repulsive partly because it signifies for us over-consumption and offends our political or moral values.  “Part and Parcel in Animal and Human Societies”. in Studies in animal and human behavior, vol. 2. pp. 115–195.

Aesthetic judgments can often be very fine-grained and internally contradictory. Likewise aesthetic judgments seem often to be at least partly intellectual and interpretative. It is what a thing means or symbolizes for us that is often what we are judging. Modern aestheticians have asserted that will and desire were almost dormant in aesthetic experience, yet preference and choice have seemed important aesthetics to some 20th century thinkers. The point is already made by Hume, but see Mary Mothersill, “Beauty and the Critic’s Judgment”, in The Blackwell Guide to Aesthetics, 2004.
Thus aesthetic judgments might be seen to be based on the senses, emotions, intellectual opinions, will, desires, culture, preferences, values, subconscious behavior, conscious decision, training, instinct, sociological institutions, or some complex combination of these, depending on exactly which theory one employs. Anthropology, especially the savanna hypothesis proposed by Gordon Orians and others, predicts that some of the positive aesthetics that people have are based on innate knowledge of productive human habitats.
It had been shown that people prefer and feel happier looking at trees with spreading forms much more than looking at trees with other forms, or non-tree objects; also Bright green colors, linked with healthy plants with good nutrient qualities, were more calming than other tree colors, including less bright greens and oranges. Are different art forms beautiful, disgusting, or boring in the same way? A third major topic in the study of aesthetic judgments is how they are unified across art forms.
We can call a person, a house, a symphony, a fragrance, and a mathematical proof beautiful. What characteristics do they share which give them that status? What possible feature could a proof and a fragrance both share in virtue of which they both count as beautiful? What makes a painting beautiful is quite different from what makes music beautiful, which suggests that each art form has its own language for the judgement of aesthetics.  At the same time, there is seemingly quite a lack of words to express oneself accurately when making an aesthetic judgement.
An aesthetic judgement cannot be an empirical judgement. Therefore, due to impossibility for precision, there is confusion about what interpretations can be culturally negotiated. Due to imprecision in the standard English language, two completely different feelings experienced by two different people can be represented by an identical verbal expression.
Wittgenstein stated this in his lectures on aesthetics and language games. A collective identification of beauty, with willing participants in a given social spectrum, may be a socially negotiated phenomenon, discussed in a culture or context. Is there some underlying unity to aesthetic judgment and is there some way to articulate the similarities of a beautiful house, beautiful proof, and beautiful sunset?  Defining it requires a description of the entire phenomenon, as Wittgenstein argued in his lectures on aesthetics. Likewise there has been long debate on how perception of beauty in the natural world, especially perception of the human form as beautiful, is supposed to relate to perceiving beauty in art or artefacts.
This goes back at least to Kant, with some echoes even in St. Bonaventure.  Aesthetics and the philosophy of art Aesthetics is used by some as a synonym for the philosophy of art, while others insist on a distinction between these closely related fields. In practice aesthetic judgement refers to the sensory contemplation or appreciation of an object (not necessarily an art object), while artistic judgement refers to the recognition, appreciation or criticism of art or an art work. What is “art? “
