Abstract

”It is often assumed that knowledge claims must be justified. But what kind of justification is required for knowledge ? . . . ” (*) presupposition: the kind of epistemic justification depends on the type of the knowledge claim and its respective knowledge claim tradeoff ’vague vs. precise’. procedere: in two - almost purely logical - case studies I account for this tradeoff and question in each case what (if any) were its general outcome wrt justification first for basic measurement statements of the form ′′ϕ(x) = r ∈ IR ± δ′′ (wrt ”measurement accuracy realism” debate) and secondly predication statements of the form ′′x is ( a case of )P′′ (wrt ”epistemic vagueness” debate).
