The definition and evaluation of art has become especially problematic since the early 20th century. Richard Wollheim distinguishes three approaches: the Realist, whereby aesthetic quality is an absolute value independent of any human view; the Objectivist, whereby it is also an absolute value, but is dependent on general human experience; and the Relativist position, whereby it is not an absolute value, but depends on, and varies with, the human experience of different humans. An object may be characterized by the intentions, or lack thereof, of its creator, regardless of its apparent purpose. A cup, which ostensibly can be used as a container, may be considered art if intended solely as an ornament, while a painting may be deemed craft if mass-produced.

Traditionally, the term art was used to refer to any skill or mastery. This conception changed during the Romantic period, when art came to be seen as "a special faculty of the human mind to be classified with religion and science". Generally, art is made with the intention of stimulating thoughts and emotions.

The nature of art has been described by Richard Wollheim as "one of the most elusive of the traditional problems of human culture". It has been defined as a vehicle for the expression or communication of emotions and ideas, a means for exploring and appreciating formal elements for their own sake, and as mimesis or representation.Jerrold Levinson, The Oxford Handbook of Aesthetics, Oxford university Press, 2003, p5. ISBN 0-1992-7945-4 Leo Tolstoy identified art as a use of indirect means to communicate from one person to another. Benedetto Croce and R.G. Collingwood advanced the idealist view that art expresses emotions, and that the work of art therefore essentially exists in the mind of the creator. The theory of art as form has its roots in the philosophy of Immanuel Kant, and was developed in the early twentieth century by Roger Fry and Clive Bell. Art as mimesis or representation has deep roots in the philosophy of Aristotle.

Definition of the term

The most common usage of the word "art," which rose to prominence after 1750, is understood to denote skill used to produce an aesthetic result. Britannica Online defines it as "the use of skill and imagination in the creation of aesthetic objects, environments, or experiences that can be shared with others." By any of these definitions of the word, artistic works have existed for almost as long as humankind: from early pre-historic art to contemporary art; however, some theories restrict the concept to modern Western societies. Much has been written about the concept of "art". Where Adorno said in 1970 "It is now taken for granted that nothing which concerns art can be taken for granted any more1,", The first and broadest sense of art is the one that has remained closest to the older Latin meaning, which roughly translates to "skill" or "craft," and also from an Indo-European root meaning "arrangement" or "to arrange". In this sense, art is whatever is described as having undergone a deliberate process of arrangement by an agent. A few examples where this meaning proves very broad include artifact, artificial, artifice, artillery, medical arts, and military arts. However, there are many other colloquial uses of the word, all with some relation to its etymology.
