"Catholics believed in life at conception. Muslims believed that it took forty-two days after conception for Allah to send an angel to transform sperm and egg into something alive...There were the outliers, too--the ancient Greeks, who said that a fetus had a "vegetable" soul, and the Jews, who said that the soul came at birth....Still, it didn't really make sense, did it? How could the moment that life began differ so much, depending on the point of view? How could the law in Mississippi say that an embryo was a human being, but the law in Massachusetts disagreed?"
