In describing numerosity as "a kind of ersatz number," Clarke and Beck fail to consider a familiar and compelling definition of numerosity, which conceptualizes numerosity as the cognitive counterpart of the mathematical concept of cardinality; numerosity is the magnitude, whereas number is a scale through which numerosity/cardinality is measured. We argue that these distinctions should be considered.There are three independent properties of a mode of presentation (m.p.) of a number being specific; being recognitional; and being canonical.
