Ezra Pound called Ulysses ‘a triumph in form’. In contrast, Holbrook Jackson deplored it as ‘chaos’, referring to ‘the arrangement of the book’ as ‘the greatest affront of all’. T. S. Eliot justified the ‘formlessness’ of Ulysses as a reflection of Joyce’s dissatisfaction with the novel form. Taking such comments as a springboard, this chapter attends to Ulysses’s capacity to produce pronounced effects of both form and formlessness, arguing that its longstanding position at the apex of the modernist canon is connected to this artful duality. Through its extensive intertextuality and practice of a gamut of generic forms, Joyce’s shape-shifting book invites its own critical insertion into ‘the tradition’. Simultaneously, it resists full absorption into any singular critical scheme through its flouting of expectations of stylistic unity and narrative closure. Ulysses achieves that exquisite balancing of pattern and disorder, or novelty and familiarity, that maximizes a work’s chance of being rated as ‘high art’. Yet its recognition as such was also considerably aided by the interpretations formulated by Joyce and his champions in the early days of the book’s reception.
