For the sake of salt, Rome created a system of remuneration (from which we get the word "salary"), nomads domesticated the camel, the Low Countries revolted against their Spanish oppressors, and Gandhi marched against the tyranny of the British. Through the ages, salt has conferred status, preserved foods, and mingled in the blood, sweat, and tears of humanity. Today, chefs of haute cuisine covet it in its most exotic forms -- underground salt deposits, Hawaiian black lava salt, glittery African crystals, and pink Peruvian salt from the sea carried in bricks on the backs of llamas.

From proverbs to technical arguments, from anecdotes to examples of folklore, chemist and philosopher Pierre Laszlo takes us through the kingdom of "white gold." With "enthusiasm and freshness" ( "Le Monde") he mixes literary analysis, history, anthropology, biology, physics, economics, art history, political science, chemistry, ethnology, and linguistics to create a full body of knowledge about the everyday substance that rocked the world and brings zest to the ordinary. Laszlo explains the history behind Morton Salt's slogan "When it rains, it pours " and looks into the plight of the salt miner, as well as spectroscopy and nuclear magnetic resonance. "Salt" is a tour de force about a chemical compound that is one of the very foundations of civilization.

French philosopher Luce Irigaray has become one of the twentieth century's most influential feminist thinkers. Among her many writings are three books (with a projected fourth) in which she challenges the Western tradition's construals of human beings' relations to the four elements--earth, air, fire, and water--and to nature. In answer to Heidegger's undoing of Western metaphysics as a "forgetting of Being," Irigaray seeks in this work to begin to think out the Being of sexedness and the sexedness of Being.

This volume is the first English translation of L'oubli de l'air chez Martin Heidegger (1983). In this complex, lyrical, meditative engagement with the later work of the eminent German philosopher, Irigaray critiques Heidegger's emphasis on the element of earth as the ground of life and speech and his "oblivion" or forgetting of air.

With the other volumes (Elemental Passions and Marine Lover of Friedrich Nietzsche, published elsewhere) in Irigaray's "elemental" series, The Forgetting of Air offers a fundamental rereading of basic tenets in Western metaphysics. And with its emphasis on dwelling and human habitation, it will be important reading not only in the humanities but also in architecture and the environmental sciences.
