No art can be judged by purely aesthetic standards, although a painting or a piece of music may appear to give a purely aesthetic pleasure. Aesthetic enjoyment is an intensification of the vital response, and this response forms the basis of all value judgements. The existentialist contends that all values are connected with the problems of human existence, the stature of man, the purpose of life. These values are inherent in all works of art, in addition to their aesthetic values, and are closely connected with them.
