what abstraction art and Idea?

ART AS ABSTRACTION OR IDEA
These exclusions seem to suggest that authentic art might typically include examples of abstraction like Malevich’s Black Square (Figure 13, p. 74) or that it remains an unrealised concept. One of the striking features of Collingwood’s The Principles of Art is just how few references are made to contemporary (i.e. 1930s) visual art; only the sculptor John Skeaping (1901–80) is noted in passing (1975: 10). The positive mention of the semi-abstract painting of Cézanne and the ideas of the art historian Bernard Berens on (1865–1959) implies a preference for art which conveys meaning through form and imaginative association.

As in Plato’s theory of ideal forms, Collingwood suggests that the actual making of the art object is inherently inferior to its conception as an ideal form. Seeing or otherwise encountering for ourselves the forms, ideas and associations of art is fundamental to the sensory experience it offers. Unless art is reproduced and shared
with the viewer in some way, it remains invisible, known only to the artist’s mind.
Although there are clearly problems with Collingwood’s theory of expression, what it does acknowledge is the extent to which visual art, like music, can and does provide insights and perspectives which are not automatically those arising from mere resemblance, or which are necessarily reducible to form. Although a cliché, the idea that an image or object can convey a thousand words at least recognises that art can be uniquely expressive of ideas and associations – sensuous, intellectual or experiential – more easily felt than
explained.
