Just as I fi nished the manuscript of this book and was about to send it to the publisher, H died. I had visited him about four days before. It is too early for me to be clear what exactly H’s death means to me. I certainly regret the fact that I came to know him so late in his life, when he was already very frail, that it was not possible to forge a proper relationship with him. But when I refl ect that he might easily already have been dead when I found out about him I am pleased to have had the chance to meet him at all.
