Focusing on lyric poetry, Mastery's End looks at important, yet neglected, issues of subjectivity in post-World War II travel literature. Jeffrey Gray departs from related studies in two regards: nearly all recent scholarly books on the literature of travel have dealt with pre-twentieth-century periods, and all are concerned with narrative genres. Gray questions whether the postcolonial theoretical model of travel as mastery, hegemony, and exploitation still applies. In its place he suggests a model of vulnerability, incoherence, and disorientation to reflect the modern destabilizing nature of travel, a process that began with the unprecedented movement of people during and after World War II and has not abated since. What the contemporary discourse concerning displacement, border crossing, and identity needs, says Gray, is a study of that literary genre with the least investment in closure and the least fidelity to ethnic and national continuities. His concern is not only with the psychological challenges to identity but also with travel as a mode of understanding and composition. Following a summary of American critical perspectives on travel from Emerson to the present, Gray discusses how travel, by nature, defamiliarizes and induces heightened awareness. Such phenomena, Gray says, correspond to the tenets of modern poetics: traversing territories, immersing the self in new object worlds, reconstituting the known as unknown. He then devotes a chapter each to four of the past half-century's most celebrated English-speaking, western poets: Elizabeth Bishop, Robert Lowell, John Ashbery, and Derek Walcott. Finally, two multi-poet chapters examine the travel poetry of Allen Ginsberg, Gary Snyder, and Robert Creeley, Lyn Hejinian, Nathaniel Mackey and others.

A profoundly inspiring and transformative argument that purposeful commitment and civic engagement can be a powerful force in today’s age of restlessness and indecision. Most of us have had this experience: browsing through countless options on Netflix, unable to commit to watching any given movie—and losing so much time skimming reviews and considering trailers that it’s too late to watch anything at all. In a book inspired by an idea first articulated in a viral commencement address, Pete Davis argues that this is the defining characteristic of the moment: keeping our options open. We are stuck in “Infinite Browsing Mode”—swiping through endless dating profiles without committing to a single partner, jumping from place to place searching for the next big thing, and refusing to make any decision that might close us off from an even better choice we imagine is just around the corner. This culture of restlessness and indecision, Davis argues, is causing tension in the lives of young people today: We want to keep our options open, and yet we yearn for the purpose, community, and depth that can only come from making deep commitments. In Dedicated, Davis examines this quagmire, as well as the counterculture of committers who have made it to the other side. He shares what we can learn from the “long-haul heroes” who courageously commit themselves to particular places, professions, and causes—who relinquish the false freedom of an open future in exchange for the deep fulfillment of true dedication. Weaving together examples from history, personal stories, and applied psychology, Davis’s “insightful without being preachy…guide to commitment should be on everyone’s reading list” (Booklist, starred review).
