The unmusical mouse in Kafka's last completed fiction who tells us about Josephine, the mouse who thinks she is Maria Callas, says at the end that, whether Josephine turns out to be a star or not, she will when she dies "joyfully lose herself amid the countless crowd of the heroes of our tribe, and quite soon (for we mice are not good at history) be forgotten on the heights of redemption like all her brethren". We humans have rarely mustered such insouciance about our own perishability, we cling to various notions of a posthumous identity parade from which someone - a god, history, DNA - will always be able to single us out. But the facts are against us, as Timothy Taylor records: "In the last 10,000 years alone, it is estimated that 100 billion human beings have died, and far fewer than 0.01 per cent are accounted for." The Buried Soul is crammed with ponderable detail about that great silent majority, the dead, and how, over the centuries, they have been disposed, in long mounds and tree-tops, de-fleshed or embalmed, foetally curled, flat out and oriented towards the dawn.
