In twenty-five years of imperial adventure, America has laid waste to its principles of democracy. The self-glorifying march of folly steps off at the end of the Cold War, in an era when delusions of omnipotence allowed the market to climb to virtual heights, while society was divided between the selfish and frightened rich and the increasingly debt-ridden and angry poor. The new millennium saw the democratic election of an American president nullified by the Supreme Court, and the pretender launching a wasteful, vainglorious and never-ending war on terror, doomed to end in defeat and the loss of America's prestige abroad. All this culminates in the sunset swamp of the 2016 election-a farce dominated by Donald Trump, a self-glorifying photo-op bursting star-spangled bombast in air. This spectacle would be familiar to Aristotle, whose portrayal of the "prosperous fool" describes a class of people who "consider themselves worthy to hold public office, for they already have the things that give them a claim to office."

Terms and phrases such as "the global village" and "the medium is the message" are now part of the lexicon, and McLuhan's theories continue to challenge our sensibilities and our assumptions about how and what we communicate. This reissue of Understanding Media marks the thirtieth anniversary (1964-1994) of Marshall McLuhan's classic expose on the state of the then emerging phenomenon of mass media. Terms and phrases such as "the global village" and "the medium is the message" are now part of the lexicon, and McLuhan's theories continue to challenge our sensibilities and our assumptions about how and what we communicate. There has been a notable resurgence of interest in McLuhan's work in the last few years, fueled by the recent and continuing conjunctions between the cable companies and the regional phone companies, the appearance of magazines such as WiRed, and the development of new media models and information ecologies, many of which were spawned from MIT's Media Lab. In effect, media now begs to be redefined. In a new introduction to this edition of Understanding Media, Harper's editor Lewis Lapham reevaluates McLuhan's work in the light of the technological as well as the political and social changes that have occurred in the last part of this century.

In 1949, lawyer, historian, and journalist Carey McWilliams stepped back to assess the state of California at the end of its first one hundred years--its history, population, politics, agriculture, and social concerns. As he examined the reasons for the prodigious growth and productivity that have characterized California since the Gold Rush, he praised the vitality of the new citizens who had come from all over the world to populate the state in a very short time. But he also made clear how brutally the new Californians dealt with "the Indian problem," the water problem, and the need for migrant labor to facilitate California's massive and highly profitable agricultural industry. As we look back now on 150 years of statehood, it is particularly useful to place the events of the past fifty years in the context of McWilliams's assessment in California: The Great Exception. Lewis Lapham has written a new foreword for this edition.
