I will discuss four major perspectives on cognitive enhancement and morality: 1) cognitive enhancement is morally impermissible because humans are not supposed to alter what God has ordained or nature has shaped; 2) cognitive enhancement is our moral duty, because a cognitively upgraded human is a better human; 3) cognitive enhancement is morally permissible only if it is preceded by moral enhancement; 4) cognitive enhancement is morally permissible only if it is a means (...) to moral enhancement. I shall argue that the first three perspectives are less cogent than the fourth. The fourth perspective integrates cognitive and moral enhancement into one whole. I will denote it by E. (shrink)
