Capable deliberators: towards inclusion of minority minds in discourse practices

Abstract

ABSTRACT It is widely assumed that severe mental disabilities prevent relevant deliberative capacities from developing or persisting. Accordingly, excluding many people with mental disabilities from discourse practices seems justified. Against this common assumption I wish to show that the general exclusion is not justified and amounts to a form of epistemic injustice, as theorised by Miranda Fricker. The received norm of capable deliberators is connected to a specific model of deliberation. I introduce an alternative model of deliberation, which I dub the joint effort model. According to this model, people with minority minds (as I call them) add valuable cognitive diversity to the process of deliberation, which is a relevant element of epistemic improvement. In this part of the argument I rely on empirically informed theoretical work by Hélène Landemore. I scrutinise the minimal requirements of capable deliberators from the perspective of a joint effort model of deliberation, and I highlight specific beneficial contributions people with minority minds can make to discourse practices. I will argue that people with minority minds can be presumptively deemed capable deliberators and that therefore their general exclusion is unjustified.
