“As a materialist, I think it has been demonstrated that an embryo is a separate body and entity, and not merely (as some really did used to argue) a growth on or in the female body. There used to be feminists who would say that it was more like an appendix or even - this was seriously maintained - a tumor. That nonsense seems to have stopped. Of the considerations that have stopped it, one is the fascinating and moving view provided by the sonogram, and another is the survival of ‘premature’ babies of feather-like weight, who have achieved ‘viability’ outside the womb. … The words ‘unborn child,’ even when used in a politicized manner, describe a material reality.” -Christopher Hitchens, God is Not Great (pp. 220-21)
