Abstract art is the most important development in the art of this century, yet there is no book that is exclusively about abstract art, and there has never been one that sets out to explain it in everyday language. Abstract paintings are discussed here both from the point of view of their creators and from the point of view of the spectator.

Then, the kind of question repeatedly asked about abstraction is asked and answered:

• By what standards can an abstract painting be judged?

• Does abstraction set out to disregard the public's expectations and wishes? If so, is it unique in this?

• Does the viewer contribute more to an appreciation of an abstract painting than to a more traditional work?

• Does any abstract painting have a message? If so, how does it express it?

• Is it necessary to know anything about the artist himself in order to fully appreciate his work?

• Does an abstract painting require more or less skill in its execution than a traditional work?

• Is there anything more to abstraction than novelty?
