The groundbreaking classic of twentieth-century German philosophy now available in English—with an introduction by J.M. Bernstein. Helmuth Plessner’s Levels of Organic Life and the Human, draws on phenomenological, biological, and social scientific sources to offer a systematic account of nature, life, and human existence. The book considers non-living nature, plants, non-human animals, and human beings a sequence of increasingly complex modes of boundary dynamics—simply put, interactions between a thing’s insides and the surrounding world. Living things are classed and analyzed by their “positionality,” or orientation to and within an environment. According to Plessner’s radical view, the human form of life is excentric—that is, the relation between body and environment is something to which humans themselves are positioned and can take a position. This “excentric positionality” enables human beings to take a stand outside the boundaries of their own body, a possibility with significant implications for knowledge, culture, religion, and technology. A powerful and sophisticated account of embodiment, the Levels shows, with reference both to science and to philosophy, how life can be seen on its own terms to establish its own boundaries, and how, from the standpoint of life, the human establishes itself in relation to the nonhuman. As such, the book is not merely a historical monument but a source for invigorating a range of vital current conversations around the animal, posthumanism, the material turn, and the biology and sociology of cognition.

The most important work by a key figure in German thought, Helmuth Plessner’s Levels of Organic Life and the Human, originally published in 1928, appears here for the first time in English, accompanied by a substantial Introduction by J. M. Bernstein, after having served for decades as an influence on thinkers as diverse as Merleau-Ponty, Peter Berger, Habermas, and the new naturalists. The Levels, as it has long been known, draws on phenomenological, biological, and social scientific sources as part of a systematic account of nature, life, and human existence. The book considers non-living nature, plants, non-human animals, and human beings in turn as a sequence of increasingly complex modes of boundary dynamics—simply put, interactions between a thing’s insides and surrounding world. On Plessner’s unique account, living things are classed and analyzed by their “positionality,” or orientation to and within an environment. “Life” is thereby phenomenologically defined, and its universal yet internally variable features such as metabolism, reproduction, and death are explained. The approach provides a foundation not only for philosophical biology but philosophical anthropology as well. According to Plessner’s radical view, the human form of life is excentric—that is, the relation between body and environment is something to which humans themselves are positioned and can take a position. This “excentric positionality” enables human beings to take a stand outside the boundaries of their own body, a possibility with significant implications for knowledge, culture, religion, and technology. Plessner studied zoology and philosophy with Hans Driesch in the 1910s before embarking on a highly productive philosophical career. His work was initially obscured by the superficially similar views of Max Scheler and Martin Heidegger and by his forced exile during World War II. Only in recent decades, as scholarship has moved more squarely into engagement with issues like animality, embodiment, human dignity, social theory, the philosophy of technology, and the philosophy of nature, has the originality and depth of Plessner’s vision been appreciated. A powerful and sophisticated account of embodiment, the Levels shows, with reference both to science and to philosophy, how life can be seen on its own terms to establish its own boundaries, and how, from the standpoint of life, the human establishes itself in relation to the nonhuman. As such, the book is not merely a historical monument but a source for invigorating a range of vital current conversations around the animal, posthumanism, the material turn, and the biology and sociology of cognition. This modern philosophical classic, long-awaited in English translation, is a key book both historically and for today’s interest in understanding philosophy and social theory together with science, without reducing the former to the latter.

A modern classic, this powerful and sophisticated account of embodiment was first published in German in 1928 and now appears in English for the first time. With reference simultaneously to science, social theory, and philosophy, Plessner shows how life can be seen on its own terms to establish its own boundaries. Plessner's account of how the human establishes itself in relation to the nonhuman will invigorate a range of current conversations around the animal, posthumanism, the material turn, and the biology and sociology of cognition.

Plessner (1892-1985), a onetime student of Husserl and contemporary of Heidegger, achieved recognition as a German social philosopher who helped establish philosophical anthropology as a discipline in the post-World War II decades. Anticipating the rise of German fascism in The Limits of Community (1924), he presents the appeal and dangers of rejecting modern society for the sake of a political ideal-based community. Translator Wallace (philosophy, Sonoma State U., California) provides a balanced introduction to Plessner's Max Weber-influenced ideas. The volume lacks an index.

The search for life in the solar system and beyond has to date been governed by a model based on what we know about life on Earth (terran life). Most of NASA's mission planning is focused on locations where liquid water is possible and emphasizes searches for structures that resemble cells in terran organisms. It is possible, however, that life exists that is based on chemical reactions that do not involve carbon compounds, that occurs in solvents other than water, or that involves oxidation-reduction reactions without oxygen gas. To assist NASA incorporate this possibility in its efforts to search for life, the NRC was asked to carry out a study to evaluate whether nonstandard biochemistry might support life in solar system and conceivable extrasolar environments, and to define areas to guide research in this area. This book presents an exploration of a limited set of hypothetical chemistries of life, a review of current knowledge concerning key questions or hypotheses about nonterran life, and suggestions for future research.

The author of the world wide best-seller, Small Is Beautiful, now tackles the subject of Man, the World, and the Meaning of Living. Schumacher writes about man's relation to the world. man has obligations -- to other men, to the earth, to progress and technology, but most importantly himself. If man can fulfill these obligations, then and only then can he enjoy a real relationship with the world, then and only then can he know the meaning of living. Schumacher says we need maps: a "map of knowledge" and a "map of living." The concern of the mapmaker--in this instance, Schumacher--is to find for everything it's proper place. Things out of place tend to get lost; they become invisible and there proper places end to be filled by other things that ought not be there at all and therefore serve to mislead. A Guide for the Perplexed teaches us to be our own map makers. This constantly surprising, always stimulating book will be welcomed by a large audience, including the many new fans who believe strongly in what Schumacher has to say.
