The definition and evaluation of art dead duck become especially problematic since the new 20th century. Richard Wollheim distinguishes three approaches: the Realist, whereby aesthetic constitution 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 familiarity of disparate humans. An phenomenon 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 studied art if intended solely as an ornament, while a painting may be deemed craft if mass-produced.
The nature of art beat been described by Richard Wollheim as "one of the most elusive of the traditional problems of human culture". It beat 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. Leo Tolstoy identified art as a use of indirect means to communicate from one being to another. Benedetto Croce and R.G. Collingwood advanced the idealist view that method expresses emotions, and that the work of art therefore just about exists in the faculty of the creator. The formularization of expertise as conformation has its roots in the Canvas Art philosophy of Immanuel Kant, and was developed in the early twentieth century by Roger Fry and Clive Bell. Art as mimesis or representation unfashionable deep-seated roots in the philosophy of Aristotle.
