 Obviously, one could pile up quotations of the same kind (see, among others, Cohen 1992, de Gandt 1986, Dhombres 1993, Epple 1997, Ferreirós and Reck 2020, Fleckenstein 1955, Granger 2003, Høyrup 2005, Laugwitz 1993, Novy 1981, Reck 2009, Tappenden 2005, Weiss 1939, Wisan 1981) but that would not be very interesting. Even in mathematics style ranges from ‘individual styles’ to ‘national styles’ to ‘epistemic styles’, among others. What is needed is first of all an understanding of the major contexts in which appeal to ‘style’ in mathematics occurs, although this essay will not contain much discussion of ‘individual styles’ (examples of such would include, to follow a suggestion by Enrico Bombieri, the “very personal” styles of Euler, Ramanujan, Riemann, Serre and A. Weil).
