Argues people can have conflicting duties
E.g doctor sees it her duty to keep terminally ill patient from pain but is also her duty to avoid killing patient
Ross' duties we must do: 1) Keep our promises, 2) Pay back harm we do to others, 3) Not injure others, 4) Return services given to us by others, 5) Not harm innocent, 6) Look after parents
Duties called Prima Facie (at first face) ---> if no conflicting duties – each duty = absolute, if conflicting duties – intuition will tell you what to do
Kant's example mad axe murderer –Kant says tell him an evasive truth – Ross argues evasion = unnecessary, lie to maniac ---> you have PRIMA FACIE to protect innocent
Majority = agree with this – Ross argues this is because careful thinking reveals an intuitive truth: victim's life more important than problem of lying
Ross argues judgements on Prima Facie will be intuited truth
"The moral order expressed in these duties is just as much part of the fundamental nature of the universe"
What is right in a moral situation is unique to that specific situation – explains why moral judgements differ
