Descriptions and Unknowability
In a recent paper Horsten embarked on a journey along the limits of the domain of the unknowable. Rather than knowability simpliciter, he considered a priori knowability, and by the latter he meant absolute provability, i.e. provability that is not relativized to a formal system. He presented an argument for the conclusion that it is not absolutely provable that there is a natural number of whi...
متن کاملOne wage of unknowability
Suppose for reductio that I know a proposition of the form p and I don’t know p. Then by the factivity of knowledge and the distribution of knowledge over conjunction, I both know and do not know p; which is impossible. Propositions of the form p and I don’t know p are therefore unknowable. Their particular kind of unknowability has been widely discussed and applied to such issues as the realis...
متن کاملA Kripkean Approach to Unknowability and Truth
We consider a language containing partial predicates for subjective knowability and truth. For this language, inductive hierarchy rules are proposed which build up the extension and anti-extension of these partial predicates in stages. The logical interaction between the extension of the truth predicate and the anti-extension of the knowability predicate is investigated.
متن کاملDealing with Unknowability in Formal Argumentation
In this position paper we discuss the importance of giving a proper account of unknowability in argument-based reasoning, suggest that existing formal tools are not fully adequate in this respect and lay down the basics of a research program in this direction.
متن کاملMultiple Descriptions , Error Concealment , and Re ned Descriptions for Image
{ This paper demonstrates the conservative nature of a multiple description approach to image and video coding, by showing that error con-cealment of a sub-optimally partitioned coded image stream yields comparable results under realistic conditions. Rather than use the non-orthogonal transforms of multiple description coding, which result in excess rate when both streams are received, a standa...
