It’s the idea that being of use to someone is what gives one a true awareness of one’s worth. If you put it the other way around, a person who isn’t of any use to others has no worth at all. That’s what you are saying, isn’t it? If one takes that to its logical conclusion then the lives of newborn babies, and of invalids and old people who are bedridden, aren’t worth living either. How could this be?
