Book excerpt: In the Name of Friendship: Deguy, Derrida and "Salut" centres on the relationship between poet Michel Deguy and philosopher Jacques Derrida. Translations of two essays, "Of Contemporaneity" by Deguy and "How to Name" by Derrida, allow Christopher Elson and Garry Sherbert to develop the implications of this singular intellectual friendship. In these thinkers’ efforts to reinvent secular forms of the sacred, such as the singularity of the name, and especially poetic naming, Deguy, by adopting a Derridean programme of the impossible, and Derrida, by developing Deguy's ethics of naming through the word "salut," situate themselves at the forefront of contemporary debates over politics and religion alongside figures like Alain Badiou and Jean-Luc Marion, John Caputo and Martin Hagglund.
