This essay analyzes how a rhetorical culture emerged in which the Supreme Court of the United States assumed corporations were constitutional persons under the Fourteenth Amendment. Approaching rhetorical culture from a networked standpoint, I argue that corporate personhood emerged from Southern Pacific Railroad Co.’s networks and alliances with environmental preservationists, politicians, publics, lawyers, judges, and immigrants in the late 19th century. Contributing to literatures on rhetorical culture and agency, this study shows how Southern Pacific Railroad Co., through networks of influence and force, was a rhetorical subject that shaped a networked rhetorical culture that expanded the boundaries of the Fourteenth Amendment even though the Supreme Court of the United States had not worked out the philosophical underpinnings of corporate personhood. Corporate personhood remains theoretically restrained by legal discourses that reduce subjectivity to a singular, speaking, human subject.
