The complex idea of "species" has evolved over time, yet its meaning is far from resolved. This comprehensive work takes a fresh look at an idea central to the field of biology by tracing its history from antiquity to today. John S. Wilkins explores the essentialist view, a staple of logic from Plato and Aristotle through the Middle Ages to fairly recent times, and considers the idea of species in natural history-a concept often connected to reproduction. Tracing "generative conceptions" of species back through Darwin to Epicurus, Wilkins provides a new perspective on the relationship between philosophical and biological approaches to this concept. He also reviews the array of current definitions. Species is a benchmark exploration and clarification of a concept fundamental to the past, present, and future of the natural sciences.

Part autobiography, part philosophical rumination, this evocative conservation odyssey explores the deep affinities between humans and our original habitat: grasslands. In a richly drawn, anecdotally driven narrative, Joe C. Truett, a grasslands ecologist who writes with a flair for language, traces the evolutionary, historical, and cultural forces that have reshaped North American rangelands over the past two centuries. He introduces an intriguing cast of characters-wildlife and grasslands biologists, archaeologists, ranchers, and petroleum geologists-to illuminate a wide range of related topics: our love affair with turf and how it manifests in lawns and sports, the ecological and economic dimensions of ranching, the glory of cowboy culture, grasslands and restoration ecology, and more. His book ultimately provides the background against which we can envision a new paradigm for restoring rangeland ecosystems-and a new paradigm for envisioning a more sustainable future.

Randolph Bourne was only thirty-two when he died in 1918, but he left a legacy of astonishingly mature and incisive writings on politics, literature, and culture, which were of enormous influence in shaping the American intellectual climate of the 1920s and 1930s. This definitive collection, back in print at last, includes such noted essays as "The War and the Intellectuals," "The Fragment of the State," "The Development of Public Opinion," and "John Dewey's Philosophy." Bourne's critique of militarism and advocacy of cultural pluralism are enduring contributions to social and political thought, sure to have an equally strong impact in our own time. In their introduction and preface, Olaf Hansen and Christopher Lasch provide biographical and historical context for Bourne's work.

If humans are to understand and discover ways of addressing complex social and ecological problems, we first need to find intimacy with our particular places and communities. Cultivating a relationship to place often includes a negotiating process that involves both science and sensibility. While science is one key part of an adaptive and resilient society, the cultivation of a renewed sense of place and community is essential as well.Science and Sensibility argues for the need for ecology to engage with philosophical values and economic motivations in a political process of negotiation, with the goal of shaping humans' treatment of the natural world. Michael Vincent McGinnis aims to reframe ecology so it might have greater "trans-scientific" awareness of the roles and interactions among multiple stakeholders in socioecological systems, and he also maintains that deep ecological knowledge of specific places will be crucial to supporting a sustainable society. He uses numerous specific case studies from watershed, coastal, and marine habitats to illustrate how place-based ecological negotiation can occur, and how reframing our negotiation process can influence conservation, restoration, and environmental policy in effective ways.
