Inspired by the commonplace books and epistolary tradition of the sixteenth and seventeenth centuries, in which writers ranged through science, philosophy, music, theology, poetry, and anything else that struck their fancies, this book is a collaboration, an improvisation in two voices. Drawing on a variety of traditions and a cloud of witnesses, from Amos Wilder, Paul Ricoeur, and Theodor Adorno to Michael Taussig and Zhao Dongming, along with wide-ranging riffs on Hebrew and Christian scriptures, the authors search reality's mysteries with wit and insight.
