 Stein’s theory of emotions is propounded in her Empathy-book (esp. 1917: 65–72[48–54], 116–124[98–106]) and in the Beiträge (1922: 21–29[21–32], 132–138[157–164], 181[217–218]); see also 1920/2004: 128–129, 136–140). It represents a complex elaboration of the role that affectivity plays in the constitution of personhood, on how emotions relate to expression, motivation and volition, and how affective states of others can be empathically grasped. Accordingly, Stein’s philosophy of emotions intersects with both her philosophy of psychology and her theory of empathy. While influenced by Scheler (esp. 1916/1926), Stein’s account is highly original, in particular regarding the analysis of moods and sentiments, different levels of affective depth, and a fine-grained elaboration of the “stratification” of the emotive live of persons.
