不明確的答案

對同一個問題的不同的科學研究有時可能使得外行無所適從,當他們設法瞭解一個人的生命究竟從哪一個時刻開始的時候,卻得到了多個答案。 可是,也許我們還記得現代科學對有關死亡的時刻也有莫衷一是的傳統假定。隨著越來越多的科學知識積累,生命的肇始和終結已經更加難以定義了。現在要查明這兩者的特殊時刻確實是非常困難的。在我們真正能夠回答這些難題之前,似乎仍然需要瞭解更多(和發展更精確的術語學)。
Conception

No definite answer

These different scientific approaches to the same problem may sometimes confuse the layperson who tries to learn at what particular moment a human life begins. However, we may well remember that the advances of modern science have also shattered many traditional assumptions about the exact moment of death. With our increasing scientific knowledge, the beginning as well as the end of life have become more difficult to define. Indeed, it is now very hard to pinpoint any specific moment for either. It seems that we need to know still more (and develop a more precise terminology) before we can really answer these difficult questions.
