The focus of the paper is on the logic of clarity and the problem of higherorder vagueness. We first examine the consequences of the notion of intransitivity of indiscriminability for higher-order vagueness, and compare different theories of vagueness understood as inexact or imprecise knowledge, namely Williamson’s margin for error semantics, Halpern’s twodimensional semantics, and the system ...

Over the past 15 years, ‘platform of values’ texts presenting core values have become common in most Swedish public authorities. This article presents a study how this genre is understood and used professional practices. The aim to show semiotic vagueness such serves number previously under-researched purposes organizations, including, rather paradoxically, concrete goal achievement. framework ...

This paper addresses the question of how to model the application of vague predicates like tall and bald to plural subjects like John and Mary and the men. In other words, we are interested in developing a logical analysis for natural language sentences like Mary is tall and The men are bald. In the past 30 years, much research has been devoted to finding the proper logical framework to model t...

It has been argued that Classical Epistemicism and classical probability theory fail to characterize this attitude, and that we must therefore abandon classical logic or classical probabilities in the presence of ...
