The two objects of moral judgement are man and conduct. There are accordingly two kinds of moral judgement. In order to distinguish these two categories some ethicist introduce the two terms "moral goodness" and "moral rightness": "moral-goodness" for the judgement of man`s morality; and "moral rightness" for describing the moral quality of conducts. Such-distinction can be traced back to G. E. Moore`s "Principia Ethica".
