Cognitive neuroenhancement involves the use of medical interventions to improve normal cognitive functioning such as memory, focus, concentration, or willpower. In this paper I give a Kantian argument defending the use of CNE in science, scholarly research, and creative fields. Kant’s universal law formulation of the categorical imperative shows why enhancement is morally wrong in the familiar contexts of sports or competitive games. This argument, however, does not apply to the use of CNE in higher education, scholarly or scientific research, (...) or creative endeavors such as visual art, fiction or poetry, or musical composition. This is because performance in these areas is embedded within practices that differ in morally significant ways from competitive practices. This important difference provides good reason to think that there is nothing morally wrong with the use of CNE in these areas. My approach is not simply to assume a full-fledged Kantian ethical theory and apply it straight away to the enhancement issue but to establish a reflective equilibrium between our moral intuitions, moral principles that support those intuitions, and the nature of the practices involved.
