It has frequently been lamented that while the human species has made immense progress in science it is nevertheless ethically backward. This ethical backwardness is all the more dangerous because the advanced state of scientific knowledge has made available a technology with which we are able to destroy ourselves—indeed a technology which may have got so much out of hand that we may not even have the capacity to prevent it from destroying us.

2 Even St Francis has a not too clear record on this question. One of his disciples cut a trotter off a living pig, to give to St Francis who was ill. St Francis told the disciple to apologize to the owner of the pig, not for his cruelty but for having damaged the property.

6 It is hard to think of any influential philosopher who holds the imperativist theory as I have crudely stated it. R. M. Hare makes a more subtle comparison between ethical sentences and imperatives and holds that ethical sentences are essentially prescriptive. See Hare, R.
