Because of the importance of the Judeo-Christian tradition in America, it is important to understand abortion as dealt with in the Old Testament. The most significant fact is that it is never mentioned.

We recognize that to many people such a statement of cold biological fact misses something essential about the developing fetus. We recognize that there is a strong inclination to assign personhood or a soul to the single cell that results from fertilization on the grounds that it represents “potential life.” Our position is that this inclination, as strongly as it may be favored on religious or social grounds, has no basis in science because, as we point out in Chapter 1, personhood and soul are simply not scientific concepts.

The net result is that slightly fewer than a third of all conceptions lead to a fetus that has a chance of developing. In other words, if you were to choose a zygote at random and follow it through the first week of development, the chances are less than one in three that it would still be there at full term, even though there has been no human intervention. Nature, it seems, performs abortions at a much higher rate than any human society. It is simply not true that most zygotes, if undisturbed, will produce a human being.
