they establish committees across France to collect news and distribute the paper, and advocated a column known as the "Chronicle of the Workers' Memory" to allow workers to express their opinions. Foucault wanted an active journalistic role in the paper, but this proved untenable, and he soon became disillusioned with Libération, believing that it distorted the facts; he did not publish in it until 1980. In 1975 he had an LSD experience with Simeon Wade and Michael Stoneman in Death Valley, California and later wrote "it was the greatest experience of his life, and that it profoundly changed his life and his work". In front of Zabriskie Point they took LSD while listening to a well-prepared music program: Richard Strauss's Four Last Songs, followed by Charles Ives's Three Places in New England, ending with a few avant-garde pieces by Stockhausen. According to Wade, as soon as he came back to Paris, Foucault scrapped the second History of Sexuality's manuscript, and totally rethought the whole project. The History of Sexuality and Iranian Revolution: 1976–1979 In 1976, Gallimard published Foucault's Histoire de la sexualité: la volonté de savoir (The History of Sexuality: The Will to Knowledge), a short book exploring what Foucault called the "repressive hypothesis". It revolved largely around the concept of power, rejecting both Marxist and Freudian theory. Foucault intended it as the first in a seven-volume exploration of the subject. Histoire de la sexualité was a best-seller in France and gained positive press, but lukewarm intellectual interest, something that upset Foucault, who felt that many misunderstood his hypothesis. He soon became dissatisfied with Gallimard after being offended by senior staff member Pierre Nora. Along with Paul Veyne and François Wahl, Foucault launched a new series of academic books, known as Des travaux (Some Works), through the company Seuil, which he hoped would improve the state of academic research in France. He also produced introductions for the memoirs of Herculine Barbin and My Secret Life. Foucault's Histoire de la sexualité concentrates on the relation between truth and sex. He defines truth as a system of ordered procedures for the production, distribution, regulation, circulation, and operation of statements. Through this system of truth, power structures are created and enforced. Though Foucault's definition of truth may differ from other sociologists before and after him, his work with truth in relation to power structures, such as sexuality, has left a profound mark on
