As a case study of the changing mentalities that emerged in colonial India, this article analyses a discussion that took place among several munshis (secretaries trained in Persian to run the affairs of princely states), and also provides a translation and edition of the text. The subject was a short polemical letter refuting the immortality of the soul, published around 1850 in the Simla Akhbār (Simla News). The main question entertained in this correspondence was not the merit of the sceptical argument, based in part on modern medical findings, but the potential public impact of dismissing a religious doctrine that sustains morality. Two of the participants in this conversation, Shivaprasad and Sital Singh, displayed the full range of changes that made the nineteenth century so extraordinary, and the way they responded illustrates some of the salient features and stages of this process, including the difficulty of foreseeing the elimination of much of the system for which munshis were trained.
