This essay investigates the starkly contrasting affective states of seventeenth-century spiritual subjects. Whilst the self-inscriptions of Calvinists such as John Bunyan are characterised by an unassuagable anxiety, the Journal of the founder of the Quaker movement, George Fox, charts his transition from a position of anxiety to an equally overwhelming and unshakeable spiritual, social and subjective confidence. Locating its argument in relation to the critical debates about early modern masculinity and the specificities of Quaker doctrine, it concludes that Fox’s confidence is rooted in a heteronomous subjectivity predicated on the Quaker theological cornerstone of the indwelling Christ.
