shuffled like a pack of cards. I believe one of the essential characteristics of the archaeologist is a curiosity about past arrangements of things and people. The other driving force, perhaps a less worthy one, is a desire to get away from an unsatisfactory or unsatisfying present, too complex or uninteresting to be faced, into a supposedly simpler world of the reconstructed past. This is an escapism. But, of course, this simpler world is simpler to the outsider; the more one gets to know of the past history of mankind, the more complex it seems to be, so it's no escape I I think there are intellectual satisfactions to be got in the field from attempting to sort out the pattern of evidence, and in the lab from the use of an ever-growing battery of equipment to the same end. Both of these are like the work of the detective and forensic scientist in their investigations; indeed, the training for the one is a good training for the other. Well, this is the intellectual side. Then there's the emotional satisfaction of studying human behaviour, civilizations and the past with all their varied skills, some of them very beautiful. Those of us who care for our own family histories, usually care also for the wider story of mankind. That's what attracts me to archaeology. Masefield: Do you think we shall eventually know all that is knowable about the past? What happens when all ancient sites have been destroyed by excavation and there is nothing left to find? Harley: We can never get all the factual information about the past; much has already gone beyond recall, as I see it, even by the most subtle of scientific techniques. For example, I can't see any possible way of discovering what name your great-grandmother gave her cat, if it is not recorded in any of her papers or was never told to your parents. But I can imagine the possibility of discovering her blood group if her bones became available. This raises the question, not maybe important just now, but it may be important someday, of just how much detail we want to know about the past. Are we interested in Julius Caesar's dog? We can go too far, of course, so when we have learned all Page 7
