Monroe Beardsley, "The Aesthetic Point of View"

To adopt an aesthetic point of view with regard to X is to take an interest in whatever aesthetic value that X may possess or that is obtainable my means of X.

The aesthetic value of X is the value that X possesses in virtue of its capacity to provide aesthetic gratification when correctly and completely experienced.

Gratification is aesthetic when it is obtained primarily from attention to the formal unity and/or the regional qualities of a complex whole, and when its magnitude is a function of the degree of formal unity and/or the intensity of regional quality.

Questions:

Beardsley himself raises some very pertinent ones: is there such a type of gratification? And what justification is there for calling this type of gratification 'aesthetic'?

What does he mean by 'formal'?
