 Consider the type of case where we can act in a way that diminishes the well-being of a person who lives above any plausibly construed threshold. However, we will diminish the person’s well-being to a level still clearly above the threshold. For example, someone breaks into the garage of a mansion and steals the new convertible while the wealthy owner is at his penthouse in the city. This theft is not likely to cause the wealthy person’s well-being to fall below any plausibly construed threshold of harm, and thus according to  (III)  does not harm him. This seems implausible. Such a case is normally understood as a case in which the affected person is clearly harmed. More generally, the objection is that the threshold conception is under-inclusive in interpreting which acts we consider harmful.
