Oppo examines the border between philosophy and literature, framing his reading of Lewis Carroll using Deleuze's analysis in The Logic of Sense, arguing that the border between philosophy and literature must be explored in the context of language, meaning, and reference. The contrasting perspectives of objectivity and subjectivity, where meaning is relational, is one way of conceptualizing this borderland; Deleuze conceives of this border as the contrast between surface and depth. Oppo argues that sense has a dynamic structure where inside and outside are entangled, as in a Mobius strip, and that this structure reveals that all sense is rooted in nonsense. Oppo suggests the fragility of sense, as it constantly 'stutters' and threatens to fall into the abyss of nonsense.
