Reviewed by: When the Medium Was the Mission: The Atlantic Telegraph and the Religious Origins of Network Culture by Jenna Supp-Montgomerie Sonia Hazard Jenna Supp-Montgomerie, When the Medium Was the Mission: The Atlantic Telegraph and the Religious Origins of Network Culture (New York: New York University Press, 2021) In 1858, the Atlantic Telegraph Company announced the opening of the trans-atlantic telegraph. It barely worked. After three weeks of unreliable functioning, the connection went forever silent. What is odd, considering the failure, is that the US public went gaga for the telegraph and its promise of a more connected United States. The jubilant popular reception of the cable is the subject of Jenna Supp-Montgomerie’s bracing new book When the Medium Was the Mission. Interweaving historical and theoretical analysis through four chapters, she advances three arguments: first, the reception of the telegraph was religious; second, the telegraph helps us to understand the religious origins of the concept of “network”; and finally, it is the failures of networks that explain their imaginary and affective persistence. To begin, a major historical contribution of the book is to demonstrate how thoroughly religion saturated the telegraph’s reception in the United States. Two chapters (the first and third) focus on the response of religious institutions. Chapter one examines the American Board of Commissioners of Foreign Missions, especially the efforts of the Board’s missionary Cyrus Hamlin who, in 1847, traveled to Constantinople to sell the telegraph to the sultan [End Page 162] Abdülmecid I. Hamlin and other missionaries believed that the telegraph was the key to the Protestant conversion of the Ottoman Empire. Chapter three presents a striking case study of the Oneida Community, the utopian group known for its plural marriage practices, who saw the telegraph as the harbinger of the coming unity of the world. The Oneidans’ newspaper The Circular announced this technological breakthrough with the thumping headline: “NO MORE DISTANCE! NO MORE WAR! THE CONTINENTS UNITED” (128). Supp-Montgomerie also shows that it was not only confessing Protestants who greeted the telegraph with passion. A larger aim of the book is to demonstrate that “religion” may be found in the “diffuse public form” (13) of Protestantism in the nineteenth-century US. This is similar to what other scholars have termed the “Protestant secular.” The most overt example of this pervasive religiosity is the famous first telegraph message on the regional Baltimore-Washington line, conveyed by Samuel Morse in 1847: “WHAT HATH GOD WROUGHT.” Supp-Montgomerie digs up many other gems. Congressional debate on a bill that would finance the transatlantic cable, for instance, included several mock amendments meant to equate the proponents with religious fanatics. One dismissive congressman suggested that half the allocated money ought to fund mesmerism. Another implored his colleagues to furnish part of the funds to the Millerites—the evangelical sect that waited, and waited, for the world to end in 1844. That the telegraph project was ridiculed as comparable to quackery or a humiliated millenarian movement shows that even its critics detected something religious about it, if only to point out that in both cases, the promise far outstripped the reality. When the Medium Was the Message uses the example of the telegraph as a springboard for advancing even bolder claims about religion and media. It is not only that the reception of the telegraph was religious (both within religious institutions and in terms of religion’s “diffuse public form”). Religion seeded “network culture” more generally. What is a network? Put simply, it is “a form of technological and social life organized around multiple links among a set of nodes” (17). The transatlantic telegraph cable connecting two endpoints is thus an elementary form of more complex networks, notably the Internet. More than a description of a spatial arrangement, however, on Supp-Montgomerie’s account, a network is an “imaginary” (6) or an “aesthetic of communication” (18). In other words, it is a social phenomenon that furnishes a way of thinking, speaking, and feeling. Most importantly for the author, it is driven by affect. A concept that has recently attracted extensive theoretical attention, affect refers to a nonlinguistic force that is transmittable, not under...
