“… Do not offer a dry repetition of things you have already said. Do not plod laboriously through all the stages of an argument that should anyway have been clear enough on the way through; your summary should be revelation rather than repetition. You may want to recapitulate briefly the essential points from what has been gone before, but chiefly you will wish to show, not what has already been spelled out, but where it has now all led. Show how all of what precedes was necessary in order to be able to give a satisfactory answer. Try to distil the essence of your argument in a way that adds at least one final thought – a thought that grows out what you have just been saying without repeating it, and which makes the last neat link with the original question in the title."
