Now if we have a curve drawn on a piece of paper representing an average ratio of persistence, you will agree that authentic development must be demonstratedby a register alternately ascending and descending the level of our original curve of homogeneous development. Such an image, or, if you prefer it, such a geometrical figure, is dialectically implied precisely by the notion, in itself, of an average ratio of progress. Noone would deny that.
