I was thinking of Whose Body?—and the mysteries the body in the novel hides then reluctantly yields—while reading Angela Franks’s new book, Body and Identity: A History of the Empty Self. But there is one commonality as we ricochet back to this thorny “Whose body?” question. This is the answer modernity has challenged, however, as Carl Trueman argues in The Rise and Triumph of the Modern Self. In the fifth chapter, Franks turns to the challenges to the Christian view of the self in early modernity, including Locke, Rousseau and his “doxic self” (the emphasis on appearance over fixed identity—a form of liquid self), and Kant’s “procedural self” (emphasis on the person as his own master). Body is not just a body but a human person, and this matters.
