“To me, it is entirely clear that the relation between the rhythmics of verse and prose is the same as that between arithmetic and integral calculus. In arithmetic we sum up individual items; in integral calculus we deal with sums, series. The prose foot is measured, not by the distance between stressed syllables, but by the distance between (logically) stressed words . And in prose, just as in integral calculus, we deal not with constant quantities (as in verse and arithmetic) but with variable ones. In prose, the foot is always a variable quantity, it is always being either slowed or accelerated. This, of course, is not fortuitous: it is determined by the emotional and semantic accelerations and retardations in the text.22”
