In this paper I distinguish between different kinds of failures of aesthetic judgements with a view to exploring a form of failure that involves the outright omission of aesthetic judgement. Such omissions come to pass when an object of attention could or ought to have been experienced and judged aesthetically but where such an experience or judgement simply failed to arise, and can be traced back to at least three kinds of reason: (1) lack of aesthetic quality; (2) lack of appropriate ontological status; and (3) lack of aesthetic prominence. I shall examine some aspects of this kind of failure and argue that a missed opportunity to experience an object of attention’s aesthetic character is a missed opportunity to engage with that object’s aesthetic potential where such potential, although not always accessible to us, can nonetheless retroactively be said to pertain to the object in a meaningful sense also under experientially unfavourable conditions. This warrants talk of rehabilitation to some degree.
