I think this confusion leads intellectuals and artists themselves to believe that the elite arts and humanities are a kind of higher, exalted form of human endeavor.
Simplicity is the final achievement. After one has played a vast quantity of notes and more notes, it is simplicity that emerges as the crowning reward of art.
The artist . . . can leave a great many of the most fundamental aspects of culture to be picked up not from his actual words, but from his emphasis. [He can] group and stress [words] so that the reader almost unconsciously receives information which is not explicit in the sentences and which the artist would find it hard - almost impossible - to express in analytic terms. This impressionistic technique is utterly foreign to the methods of science.
Art works because it appeals to certain faculties of the mind. Music depends on details of the auditory system, painting and sculpture on the visual system. Poetry and literature depend on language.
The work of art is the object seen sub specie aeternitatis; and the good life is the world seen sub specie aeternitatis. This is the connection between art and ethics.
There is no society ever discovered in the remotest corner of the world that has not had something that we would consider the arts. Visual arts - decoration of surfaces and bodies - appears to be a human universal.
Very few people possess true artistic ability. It is therefore both unseemly and unproductive to irritate the situation by making an effort. If you have a burning, restless urge to write or paint, simply eat something sweet and the feeling will pass.
