As in these articles I intend to skip about from one part of my argument to another, as occasion demands, I might perhaps give them a greater appearance of shape by laying down as a preliminary three theses that I want to maintain.
R.........p(r) .........a(r) .........A
I take (R) to represent reality. As one goes from left to right one gets further and further from reality. The first step away being p(r), that is the artist’s interpretation of nature. The next step a(r) being an art using abstractions (a), with a certain representative element (r). The element (a) owes its significance to, and is dependent on the other end (A) of this kind of spectrum – a certain “tendency to abstraction.” I assert that there are two arts, the one focussed round (R), which is moved by a delight in natural forms, and the other springing from the other end, making use of abstractions as a method of expression. I am conscious that this is the weak point of my argument, for I cannot give body to this conception of the “expressive use of abstraction” till later on in the series.
