This paper furthers the understanding of Nietzsche's project of increasing the prevalence of higher individuals. I do this by opposing the dominant tendency in Nietzschean scholarship of constructing a single ideal-type. I argue that Nietzsche actually describes multiple higher types, with incommensurable physiological and psychological characteristics, and that attempts to collapse these into one type obscure the nuance and richness of his thought. Furthermore, I claim that higher types are not ahistorical ideals; instead, their emergence relates closely to existing psychological (...) and physiological conditions in society. The artistic-genius type, for example, is characterised by his sensitivity to stimuli and plays a vital role in injecting creativity into culturally uniform societies. He is, however, a counter-productive role model for diverse modern societies, characterised by an abundance of stimuli and widespread reactivity. In response to such conditions, Nietzsche extols the virtue of a peculiarly anti-modern type, who cultivates independence from stimuli. Interpreting higher types as multiple and historically situated is vital to carrying out the normative aspect of Nietzsche's philosophy. This role is performed by the philosophical-physician, who surveys the physiological and psychological conditions of his own age and attempts to exploit these conditions to produce future higher individuals.
