This paper offers a critique of affect theory using the analytical concept of scale that is made concrete through an ethnography of Pentecostal Christianity and an exploration of current neuroscientific thinking. Affect theory is one recent form of a Western philosophical concern about the loss of agency in modernity, what I call “agency-anxiety.” Affect theorists tend to privilege the sense of freedom gained by immediate and individual experience over the constraints of more extended experiences and collectivity. That is, affect theory often scales its analysis tightly. This paper responds with an ethnography of Pentecostal practice and exploration of work in neuroscience that describes an analytic space in which broader scales can be useful as well. Ethnography scaled beyond the instant reveals that the Pentecostal ideal of surrendering to God in a moment of abandonment often results from a “fake it until you make it” approach; in other words, from extended, effortful, willful practice. This practice leads to the formation of habits and dispositions that allow the attainment of spontaneous rupture. Likewise, neuroscience can scale out its analysis by focusing on dispositions, moods and habits, rather than simply a more immediate view. Further, “scale effects” and emergent properties in scale-to-scale relations undermine reductionism. Finally, because Pentecostals are generally right wing yet also exemplify ruptural practice, it seems that outside of a particular conjuncture, the tightly scaled eruptive moment of affect is by no means per se a productive or (politically) progressive formation. As such, making scale an explicit analytical category might help us to see agency, change, and structure more clearly.
