'Exchange is creation': The revolutionary poetics of Muriel Rukeyser and Hugh MacDiarmid

The increased cultural authority of science in the early decades of the twentieth century called into question prior cultural assumptions regarding the status of poetry as an important discipline. The debate about the changed nature of the relations between the arts and sciences assumed particular importance for the literary left, as writers, critics and intellectuals debated the role which culture would play in political revolution. In order to broaden our understanding of the left's engagement with the problem of the relationship between the arts and sciences, this article will compare the work of the leftist American poet Muriel Rukeyser with that of the Scottish nationalist and Communist poet Hugh MacDiarmid. In particular, I will explore the ways in which their understanding of the essential similarities between the arts and sciences informed their conception of the relationship between poetics and political praxis.
