The COVID-19 pandemic is nowhere near over. Some things, however, seem relatively clear. So far, the agendas of the world's most powerful actors seem unchanged—or, indeed, accelerated. Partly as a result, disease mortality and economic losses have fallen largely on poorer people, though deaths so far have been concentrated among poorer people in rich countries. Consequently, the pandemic's implications look very different at the local, subnational, and international levels—although at all levels, they thus far reflect accelerations of preexisting trends more than new departures. Many developments reflect remarkable gains in human capacity to cope with disasters—a point highlighted by comparisons to the 1919 flu and other historical events pandemics made by the authors in this forum. Those gains are particularly evident in Asia, though they look more precarious in South Asia and Southeast Asia than in East Asia; this has contributed to a marked shift in rhetoric about global “sickness” and health and seems consistent with prophecies of a coming “Asian century.” However, COVID-19 may not be a singular event like 1919 but may portend a wave of environmental emergencies; in that scenario, no world region has exhibited as much resilience as it would need.

Tonio Andrade's The Gunpowder Age is a big book. It spans roughly 800 years, in both China and Europe. Its boldest claims concern China, but Andrade delves into European history as well, making it a challenge for any one scholar to assess his evidence and arguments. Because China specialists would want to know how historians specializing in European warfare and in Western science and technology evaluate Andrade's challenges to received wisdom, the Journal of Chinese History’s editor and editorial board invited historians outside the China field to contribute to a joint review. We succeeded in recruiting a distinguished panel, all of whom have written extensively on these issues: David Parrott, author of such books as The Business of War: Military Enterprise and Military Revolution in Early Modern Europe; Philip Hoffman, author most recently of Why Did Europe Conquer the World?; Stephen Morillo, author of War in World History, among other books; and Ian Inkster, author of Science and Technology in History: An Approach to Industrial Development, among other books. This introduction provides an overview of the discussion so far, and a few additional observations from a historian who has also tried his hand at Sino-European comparisons.

Amitav Ghosh, perhaps Asia's most prominent living author, moves among many genres and across vast territories. His fiction—The Circle of Reason (1986), The Shadow Lines (1988), The Glass Place (2000), The Hungry Tide (2004), and The Ibis trilogy—takes us from Calcutta where he was born in 1956 to the Arabian Sea, Paris, London, and back again to the Indian Ocean, the Bay of Bengal, and beyond. His nonfiction—In an Antique Land (1992), Dancing in Cambodia and at Large in Burma (1998), and Countdown (1999)—rests on a PhD in social anthropology from Oxford. He went to Alexandria, Egypt, for his dissertation research. His science fiction, The Calcutta Chromosome, won the Arthur C. Clarke Award in 1997. His essays—published in The New Yorker, The New Republic, and The New York Times and collected in The Iman and the Indian (2002)—address major issues such as fundamentalism. Indeed, most of his work addresses big questions, exploring the nature of communal violence, the traces of love and longing across generations, manifold religious manifestations, and the systematic pain of colonial oppression. The deep and abiding theme of many works is anthropogenic environmental damage, now boldly and directly addressed in The Great Derangement: Climate Change and the Unthinkable (2016). Married to accomplished fellow author Deborah Baker, whose work traces the Asian peregrinations of Allen Ginsberg, the literary milieu of Laura Riding, and the complexity of Islamic conversion, Ghosh has taught at Harvard, Columbia, Queens College, and Delhi University. He has won more prizes and honorary doctorates, and been a fellow at more famous institutions and a distinguished visitor in more far-flung places, than you can shake a stick at. He even has two homes: Brooklyn and Goa. In short, Ghosh's profile makes you wonder if there might not be more than one of him.
