说自古以来都禁止堕胎，是不符合历史的。在胎儿开始动以前，堕胎都是符合世俗法的。

符合不符合宗教法不去说。

胎儿动叫做quickening，大约在五个月左右。 现在得克萨斯等一些红州禁止六周以后的堕胎，也就是说这些州的孕妇还没有殖民时代的妇女的堕胎权。

This piece describes abortion practices in use from the 1600s to the 19th century among the inhabitants of North America.... . In the British colonies abortions were legal if they were performed prior to quickening.... From 1776 until the mid-1800s abortion was viewed as socially unacceptable; however, abortions were not illegal in most states. During the 1860s a number of states passed anti-abortion laws.
