It is almost inevitable that an autobiography has to end with a chapter on unfinished business. At no point in one’s life can one decide what business can still be finished, and at some stage, the autobiography has to be delivered to the publisher. An autobiography that is mainly concerned with the author’s work can never be firmly closed, unless the author has really decided to work no more. I have certainly not done this. So I would at least like to indicate what work I now regard as complete and secure at this stage and what will still suffer debate and possibly modification.
