The understanding we gain of history and past civilizations through archaeology is highly imperfect and incomplete, and you have to be extremely careful in drawing inferences. In fact, the biggest lesson I've learned over the many years that I've engaged in archaeology is to keep an open mind.
所以，從考古學上瞭解的過去文明和歷史，是非常不完善、不完全的，進行推論時必須謹慎。事實上，學考古這麼多年，我得到的最大一個教訓，就是保持心胸開放。
