# A quotation by Etienne Montucla

[Mathematics is] the science *of the ratios of size or of number, which can have between them all things that are susceptible of augmentation or of diminution.* ... Mathematics divides up naturally into two classes; the one which one calls pure and abstract; the other those which one calls mixed, or more ordinarily physico-mathematical.

*Histoire des mathématiques* (1799)
