Book Synopsis The Identity Trap by : Yascha Mounk

Download or read book The Identity Trap written by Yascha Mounk. This book was released on 2023-09-26. Available in PDF, EPUB and Kindle. Book excerpt: One of our leading public intellectuals traces the origin of a set of ideas about identity and social justice that is rapidly transforming America—and explains why it will fail to accomplish its noble goals For much of history, societies have violently oppressed ethnic, religious, and sexual minorities. It is no surprise that many who passionately believe in social justice came to believe that members of marginalized groups need to take pride in their identity to resist injustice. But over the past decades, a healthy appreciation for the culture and heritage of minority groups has transformed into a counterproductive obsession with group identity in all its forms. A new ideology aiming to place each person’s matrix of identities at the center of social, cultural, and political life has quickly become highly influential. It stifles discourse, vilifies mutual influence as cultural appropriation, denies that members of different groups can truly understand one another, and insists that the way governments treat their citizens should depend on the color of their skin. This, Yascha Mounk argues, is the identity trap. Though those who battle for these ideas are full of good intentions, they will ultimately make it harder to achieve progress toward the genuine equality we desperately need. Mounk has built his acclaimed scholarly career on being one of the first to warn of the risks right-wing populists pose to American democracy. But, he shows, those on the left and center who are stuck in the identity trap are now inadvertent allies to the MAGA movement. In The Identity Trap, Mounk provides the most ambitious and comprehensive account to date of the origins, consequences, and limitations of so-called “wokeness.” He is the first to show how postmodernism, postcolonialism, and critical race theory forged the “identity synthesis” that conquered many college campuses by 2010. He lays out how a relatively marginal set of ideas came to gain tremendous influence in business, media, and government by 2020. He makes a nuanced philosophical case for why the application of these ideas to areas from education to public policy is proving to be so deeply counterproductive—and why universal, humanist values can best serve the vital goal of true equality. In explaining the huge political and cultural transformations of the past decade, The Identity Trap provides truth and clarity where they are needed most.

Book excerpt: Wall Street Journal, USA Today, and Publishers Weekly Bestseller! Have you heard that language is violence and that science is sexist? Have you read that certain people shouldn't practice yoga or cook Chinese food? Or been told that being obese is healthy, that there is no such thing as biological sex, or that only white people can be racist? Are you confused by these ideas, and do you wonder how they have managed so quickly to challenge the very logic of Western society? In this probing and intrepid volume, Helen Pluckrose and James Lindsay document the evolution of the dogma that informs these ideas, from its coarse origins in French postmodernism to its refinement within activist academic fields. Today this dogma is recognizable as much by its effects, such as cancel culture and social-media dogpiles, as by its tenets, which are all too often embraced as axiomatic in mainstream media: knowledge is a social construct; science and reason are tools of oppression; all human interactions are sites of oppressive power play; and language is dangerous. As Pluckrose and Lindsay warn, the unchecked proliferation of these anti-Enlightenment beliefs present a threat not only to liberal democracy but also to modernity itself. While acknowledging the need to challenge the complacency of those who think a just society has been fully achieved, Pluckrose and Lindsay break down how this often-radical activist scholarship does far more harm than good, not least to those marginalized communities it claims to champion. They also detail its alarmingly inconsistent and illiberal ethics. Only through a proper understanding of the evolution of these ideas, they conclude, can those who value science, reason, and consistently liberal ethics successfully challenge this harmful and authoritarian orthodoxy—in the academy, in culture, and beyond.

Book Synopsis Topological Solitons by : Nicholas Manton

Download or read book Topological Solitons written by Nicholas Manton. This book was released on 2004-06-10. Available in PDF, EPUB and Kindle. Book excerpt: Topological solitons occur in many nonlinear classical field theories. They are stable, particle-like objects, with finite mass and a smooth structure. Examples are monopoles and Skyrmions, Ginzburg-Landau vortices and sigma-model lumps, and Yang-Mills instantons. This book is a comprehensive survey of static topological solitons and their dynamical interactions. Particular emphasis is placed on the solitons which satisfy first-order Bogomolny equations. For these, the soliton dynamics can be investigated by finding the geodesics on the moduli space of static multi-soliton solutions. Remarkable scattering processes can be understood this way. The book starts with an introduction to classical field theory, and a survey of several mathematical techniques useful for understanding many types of topological soliton. Subsequent chapters explore key examples of solitons in one, two, three and four dimensions. The final chapter discusses the unstable sphaleron solutions which exist in several field theories.
