Among the central threads running through de Man's work is his attempt to tease out the tension between rhetoric (which de Man uses as a term to mean figural language and trope) and meaning, seeking moments in the text where linguistic forces "tie themselves into a knot which arrests the process of understanding." De Man's earlier essays from the 1960s, collected in "Blindness and Insight", represent an attempt to seek these paradoxes in the texts of New Criticism and move beyond formalism. One of De Man's central topoi is of the blindness on which these critical readings are predicated, that the "insight seems instead to have been gained from a negative movement that animates the critic's thought, an unstated principle that leads his language away from its asserted stand. . . as if the very possibility of assertion had been put into question." Here de Man tries to undercut the notion of the poetic work as a unified, atemporal icon, a self-possessed repository of meaning freed from the intentionalist and affective fallacies. In de Man's argument, formalist and New Critical valorization of the "organic" nature of poetry is ultimately self-defeating: the notion of the verbal icon is undermined by the irony and ambiguity inherent within it. Form ultimately acts as "both a creator and undoer of organic totalities," and "the final insight...annihilated the premises which led up to it."
