Ignorance and Its Disvalue

It is commonly accepted – not only in the philosophical literature but also in daily life – that ignorance is a failure of some sort. As a result, a desideratum of any ontological account of ignorance is that it must be able to explain why there is something wrong with being ignorant of a true proposition. This article shows two things. First, two influential accounts of ignorance – the Knowledge Account and the True Belief Account – do not satisfy this requirement. They fail to provide a satisfying normative account of the badness of ignorance. Second, this article suggests an alternative explanation of what makes ignorance a bad cognitive state. In a nutshell, ignorance is bad because it is the manifestation of a vice, namely, of what Cassam calls “epistemic insouciance”.
