This essay reconsiders More's letter to Brixius. It uncovers early modern understandings of self-fashioning/ethos and epistolary conventions of the period, and with these contexts, it rereads More's self-presentation or ethos-development in the letter. The essay argues that More's ethos in the letter highlights an authentic facet of himself and, thereby, gives us a glimpse of the historical More who, in the Brixius moment, is angry, but not excessively or habitually, as has sometimes been claimed.
