As Aristotle stated, scientific explanation is based on deductive argument--yet, Wesley C. Salmon points out, not all deductive arguments are qualified explanations. The validity of the explanation must itself be examined. Four Decades of Scientific Explanation provides a comprehensive account of the developments in scientific explanation that transpired in the last four decades of the twentieth century. It continues to stand as the most comprehensive treatment of the writings on the subject during these years.

Building on the historic 1948 essay by Carl G. Hempel and Paul Oppenheim, "Studies in the Logic of Explanation,” which introduced the deductive-nomological (D-N) model on which most work on scientific explanation was based for the following four decades, Salmon goes beyond this model's inherent basis of describing empirical knowledge to tells us “not only what, but also why.” Salmon examines the predominant models in chronological order and describes their development, refinement, and criticism or rejection.

Four Decades of Scientific Explanation underscores the need for a consensus of approach and ongoing evaluations of methodology in scientific explanation, with the goal of providing a better understanding of natural phenomena.

In Four Decades On, historians, anthropologists, and literary critics examine the legacies of the Second Indochina War, or what most Americans call the Vietnam War, nearly forty years after the United States finally left Vietnam. They address matters such as the daunting tasks facing the Vietnamese at the war's end—including rebuilding a nation and consolidating a socialist revolution while fending off China and the Khmer Rouge—and "the Vietnam syndrome," the cynical, frustrated, and pessimistic sense that colored America's views of the rest of the world after its humiliating defeat in Vietnam. The contributors provide unexpected perspectives on Agent Orange, the POW/MIA controversies, the commercial trade relationship between the United States and Vietnam, and representations of the war and its aftermath produced by artists, particularly writers. They show how the war has continued to affect not only international relations but also the everyday lives of millions of people around the world. Most of the contributors take up matters in the United States, Vietnam, or both nations, while several utilize transnational analytic frameworks, recognizing that the war's legacies shape and are shaped by dynamics that transcend the two countries.
