Chalres Olson`s idea of ``projective verse`` represents Black Mountain group and signals the beginning of postmodernism in poetry. His postmodern poetics, however, bears similarities to modernist poetics, especially to Pound and Williams in that his concepts of ``open verse`` and ``composition by field`` share with the elder poets`` idea of ``ideogram`` or ``objectivism,`` the features like organic form, sincerity, or poetry as an object. But Olson accepts those modernist features strategically and incorporates them into his distinguishing idea of ``objectism``, a form of antihumanism. Although they also consider nature in dynamic flux where energy transferences take place among things, Pound and Williams regard the poet as independent of nature, the poem as autonomous. This implies that poetry is simply a mimetic embodiment of nature. According to Olson, however, the poet belongs to natural processes just like things in nature, and cannot be an independent subject who controls his works. Likewise, the poem is not an autonomous object but a field belonging to the larger field of nature, the universe. For Olson, the poet ``projects`` his subject into natural processes, participating in the kinetics of the entire universe, thereby poetry is an enactment of nature instead of an embodiment of nature.
