 In the descriptive sense of “morality”, a person’s own morality cannot be a guide to behavior that that person would prefer others not to follow. However, that fact that an individual adopts a moral code of conduct for his own use does not entail that the person requires it to be adopted by anyone else. An individual may adopt for himself a very demanding moral guide that he thinks may be too difficult for most others to follow. He may judge people who do not adopt his code of conduct as not being as morally good as he is, without judging them to be immoral if they do not adopt it. However, such cases do not undermine the restriction; a guide is plausibly referred to as a morality only when the individual would be willing for others to follow it, at least if “follow” is taken to mean “successfully follow”. For it may be that the individual would not be willing for others to try to follow that code, because of worries about the bad effects of predictable failures due to partiality or lack of sufficient foresight or intelligence.
