ABSTRACT
This chapter focuses on the question of quantitativeness – of identifying the feature that makes quantitative properties quantitative. The chapter begins with two traditional attempts at capturing what makes a property quantitative – being numerical and being determinable – and argues that neither is satisfactory. The chapter then turns to influential recent proposals which, inspired by the Representational Theory of Measurement, attempt to identify particular relations as characteristic of quantitative properties. These attempts fare better than the traditional ones, but have their own limitations. It concludes with a discussion of a new recent criterion for quantitativeness, which builds on a more abstract understanding of the representational theory of measurement.
