The cochlear implant (CI) is a neuroprosthesis that allows for partial recovery of auditory function in individuals who are deaf. Despite its general efficacy, its use has been strongly opposed by a part of the deaf community that perceives deafness as a form of cultural identity, rather than a pathology. This article considers the concerns of the deaf community – which are often difficult for hearing people to understand – from a neuroethics perspective, proposing that such opposition to CI is analogous to the general population’s unease with regard to Cognitive Enhancement (CE). CE allows healthy individuals who are unsatisfied with – or would like to improve – their performance to use artificial interventions that enhance cognitive functions. The analysis reveals that, when opposing CIs, the deaf community may be protecting a set of values similar to those that the general community often evokes when voicing concerns about CE diffusion.
