Two or Three Strands to the Concept of Ignorance

This article discusses two under-explored strands to the concept of ignorance. Firstly, how ignorance relates to a subject’s degrees of belief; secondly how ignorance relates to a subject’s evidence. I also consider a third alleged strand to the concept of ignorance, which is that ignorance requires some kind of normative failure. I argue that this is false; ignorance does not essentially require any such failure. I finish with some reflections on the extent to which conceptual analysis and linguistic intuitions about the English language concept ‘ignorance’ can be relied upon to illuminate the nature of ignorance itself.
