Neuro-enhancement refers to the use of applications of modern neurosciences to make people better – smarter, happier, more sociable etc. This paper consists of analyses on claims concerning unnaturalness of neuro-enhancement. In what sense, if any, is neuro-enhancement unnatural? If neuro-enhancement is unnatural, is its unnaturalness morally noteworthy? Four possible senses of naturalness are analyzed: naturalness as normality, naturalness as suitability, naturalness as belonging, and naturalness as familiarity. None of these interpretations offers sufficient support for the view that neuro-enhancement is morally problematic because of its unnaturalness.
