为什么那么多人热衷于登山、跑马拉松、吃辣、看恐怖电影？为什么那么多人念念不忘于自己吃苦、受冻、流泪的经历？为什么那么多人的关键性成长都发生在重创之后？ 多伦多大学心理学教授保罗·布卢姆基于心理学、脑科学、认知神经科学等领域的众多新发现，为我们带来了关于苦难与幸福的全新阐释。他在书中探讨了三个主要观：一，疼痛、恐惧和悲伤等某些类型的自愿受苦能成为快乐之源；二，良好的生活不仅指快乐的生活，还包括对道德良善和意义的追求；三，有些类型的痛苦，比如抗争和克服困难导致的痛苦，是实现更高目标、度过完满人生所必xu经历的。他还在书中驳斥了流传已久的关于“人类天生就是享乐主义者，只追求快乐”的人性观，揭示人类倾向于追求更深刻、更具超越性事物的本性，从而为我们指明了通往真zheng幸福而有意义人生的方向。 作为广受欢迎的科普作家，布卢姆的写作沿袭了其畅销书《摆脱共情》《善恶之源》通俗、幽默的文风，又兼具科学性、故事性与哲学意味，对任何领域的读者来说都是一场科学与智识的饕餮盛宴。

As with any enterprise involving violence and lots of money, running a plantation in early British America was a serious and brutal enterprise. Beyond resources and weapons, a plantation required a significant force of cruel and rapacious men-men who, as Trevor Burnard sees it, lacked any better options for making money. In the contentious Planters, Merchants, and Slaves, Burnard argues that white men did not choose to develop and maintain the plantation system out of virulent racism or sadism, but rather out of economic logic because-to speak bluntly-it worked.These economically successful and ethically monstrous plantations required racial divisions to exist, but their successes were always measured in gold, rather than skin or blood. Burnard argues that the best example of plantations functioning as intended is not those found in the fractious and poor North American colonies, but those in their booming and integrated commercial hub, Jamaica. Sure to be controversial, this book is a major intervention in the scholarship on slavery, economic development, and political power in early British America, mounting a powerful and original argument that boldly challenges historical orthodoxy.

At the close of the Second World War, modernist poets found themselves in an increasingly scientific world, where natural and social sciences claimed exclusive rights to knowledge of both matter and mind. Following the overthrow of the Newtonian worldview and the recent, shocking displays of the power of the atom, physics led the way, with other disciplines often turning to the methods and discoveries of physics for inspiration.?In Physics Envy, Peter Middleton examines the influence of science, particularly physics, on American poetry since World War II. He focuses on such diverse poets as Charles Olson, Muriel Rukeyser, Amiri Baraka, and Rae Armantrout, among others, revealing how the methods and language of contemporary natural and social sciences-and even the discourse of the leading popular science magazine Scientific American-shaped their work. The relationship, at times, extended in the other direction as well: leading physicists such as Robert Oppenheimer, Werner Heisenberg, and Erwin Schrdinger were interested in whether poetry might help them explain the strangeness of the new, quantum world. Physics Envy is a history of science and poetry that shows how ultimately each serves to illuminate the other in its quest for the true nature of things.

In 1915, western farmers mounted one of the most significant challenges to party politics America has seen: the Nonpartisan League, which sought to empower citizens and restrain corporate influence. Before its collapse in the 1920s, the League counted over 250,000 paying members, spread to thirteen states and two Canadian provinces, controlled North Dakota's state government, and birthed new farmer-labor alliances. Yet today it is all but forgotten, neglected even by scholars.Michael J. Lansing aims to change that. Insurgent Democracy offers a new look at the Nonpartisan League and a new way to understand its rise and fall in the United States and Canada. Lansing argues that, rather than a spasm of populist rage that inevitably burned itself out, the story of the League is in fact an instructive example of how popular movements can create lasting change. Depicting the League as a transnational response to economic inequity, Lansing not only resurrects its story of citizen activism, but also allows us to see its potential to inform contemporary movements.

For decades, James Joyce's modernism has overshadowed his Irishness, as his self-imposed exile and association with the high modernism of Europe's urban centers has led critics to see him almost exclusively as a cosmopolitan figure.In Joyce's Ghosts, Luke Gibbons mounts a powerful argument that this view is mistaken: Joyce's Irishness is intrinsic to his modernism, informing his most distinctive literary experiments. Ireland, Gibbons shows, is not just a source of subject matter or content for Joyce, but of form itself. Joyce's stylistic innovations can be traced at least as much to the tragedies of Irish history as to the shock of European modernity, as he explores the incomplete project of inner life under colonialism. Joyce's language, Gibbons reveals, is haunted by ghosts, less concerned with the stream of consciousness than with a vernacular interior dialogue, the "e;shout in the street,"e; that gives room to outside voices and shadowy presences, the disruptions of a late colonial?culture in crisis.Showing us how memory under modernism breaks free of the nightmare of history, and how in doing so it gives birth to new forms, Gibbons forces us to think anew about Joyce's achievement and its foundations.
