I sometimes tell small children they mustn’t write their essays without doing essay plans first. If they don’t I can always tell because there are unexpected bits in all kinds of places and the final paragraph is very short. This morning I have been making a plan for my essay, but because I don’t know what the argument is yet I have to keep all the paragraphs mobile. Gradually I will start to put the post-it notes in new orders and put different kinds of arrows between them.
