The sorites paradox results from two equally plausible constraints on categorization in sorites series: a constraint of category switch between the first and the last items, and a constraint of similarity or consistent judgment for adjacent items. Following the work of D. Raffman [27,28] this paper argues that both constraints can be met if we assume that borderline cases pattern as ambiguous items between opposing categories. I first review some empirical evidence in favor of this view. I then examine how it bears on the tolerance principle, from a descriptive and from a normative viewpoint. In particular, I discuss ways in which the account of tolerance outlined in [6] can be related to Smith’s [37] fuzzy account, as well as to the similarity-based semantics for vague predicates proposed by van Rooij [34] and explored in recent work with Cobreros et al. [4].
