Abstract
This article analyzes the moral reasoning implied in a very commonly used expression, namely, "What the eye doesn't see, the heart doesn't grieve over", or "What you don't know won't hurt you." It especially deals with situations in which it is used for trying to justify acts that are, in themselves, reprehensible. For instance, when a cheating husband tries to justify his adultery by appealing to the alleged fact that he does not tell his wife about it and thus she is not harmed by it: "If you are not informed, you are not hurt" (NINH). The components of NINH reasoning are unfolded, as well as its grounds, starting from a consequentialistic, deontological, or virtue ethics perspective. Two special characteristics of NINH reasoning are discussed, namely, that it tries to bridge deontological and consequentialistic approaches of morality in a commonsense way and that it contains a special type of paternalism. Finally, some ethical implications are discussed.
