Morally Excellent Work, by Miroslav Volf

"Some years ago at a black-tie cocktail party, I was talking to a person who introduced himself to me as a graduate of Harvard University. We were chatting, so I asked him what he did. He responded, 'You will laugh when I tell you what I do.' I said, 'Well, try me.' He replied, 'I'm making urinals.' I said, 'Well most men need them . . .' And he responded, 'I'm designing and producing flush-free urinals.' What an extraordinary thing to do! Water is becoming a very scarce resource, and he was helping save a lot of it, in fact some forty thousand gallons per urinal per year! This person's work was morally excellent, not just morally permissible."
