I first encountered the work of John Corrigan in graduate school. Catherine L. Albanese had assigned his book Business of the Heart in a seminar I was taking. I loved the book, but also felt troubled by it. It focused on religious revivals, a topic I was very interested in. But his approach to revival was clearly not my approach to revival. Corrigan used a mid-nineteenth century religious awakening to offer a compelling and innovative look at a subject I had never considered historically—emotions. Corrigan was asking different questions of his sources than I did, and as a result, he came to very different conclusions than I would have.
