That Ship Has Sailed synthesizes the serious and comic to address sex, love, loss, death, belief, the afterlife, and the past. The poems are honest and direct without sacrificing “the uncertainties, mysteries, and doubts” that Keats singles out in his notion of “negative capability,” alluded to in the title poem. Amplified by the poet’s work as a traditional Irish musician and composer, language is the adhesive that brings the work together across the avant-garde to traditional forms and meters.
