Maureen L. Condic, Senior Fellow of the Westchester Institute for Ethics and the Human Person and Associate Professor of Neurobiology and Anatomy at the University of Utah School of Medicine, has written a white paper called When Does Human Life Begin? A Scientific Perspective. John Neuhaus, editor of First Things, in his foreword for this paper, says the following:
It is really far past time to clear the air of the smog that obscures and confuses debates about abortion, embryonic research, cloning, and related issues. Among the chief obfuscations and confusions is the claim that we do not know when human life begins. This frequently takes the form of claiming that the question is a matter of faith or religious belief. Nothing could be farther from the truth, as is lucidly and convincingly demonstrated in this White Paper.
When a human life begins is a question of science. The ethicist Peter Singer of Princeton University is famous, or notorious, for his advocacy of selective infanticide for babies who are born and then found to be defective in a way that makes them unwanted. Most people will find that argument morally abhorrent. But Singer is right about one thing. As he has said on many occasions, he and the pope are in complete agreement on when human life begins.
The debate in our society and others is not over when human life begins but is over at what point and for what reasons do we have an obligation to respect and protect that life. Before we can get to that argument, however, we need to clear the smog surrounding the question of when human life begins. This White Paper makes an invaluable contribution to that end.
It is sometimes said that the abortion debate is about “values” rather than “facts.” An honest debate about abortion, however, is about values based on facts. If we don’t get the facts right, we will not get our values right. Establishing by clear scientific evidence the moment at which a human life begins is not the end of the abortion debate. On the contrary, that is the point from which the debate begins.
Condic, thoroughly and systematically, provides to the reader the pertinent scientific facts concerning fertilization and embryonic development. Although some of the information will be challenging to those with little scientific background, this white paper is helpful to those interested in answering the important question of when life begins.
One particularly important point made by Dr. Condic is that people often think of the embryo as something being manufactured - that up until a certain point it is just an assemblage of parts being pieced together to make a whole. This, however, confuses the actual process of embryonic development with our understanding of modern manufacturing processes.
A car is not a car until it rolls off the assembly line—until then it is a bunch of parts in the process of becoming a car, but not there yet. Similarly, a cake is not a cake until it comes out of the oven—until then it is a variously gooey mass of flour, sugar, eggs, and butter that is gradually becoming a cake.
However, a profound difference exists between manufacturing and embryonic development. The difference is who (or what) is doing the “producing.” The embryo is not something that is being passively built by the process of development, with some unspecified, external “builder” controlling the assembly of embryonic components. Rather, the embryo is manufacturing itself. The organized pattern of development doesn’t produce the embryo; it is produced by the embryo as a consequence of the zygote’s internal, self-organizing power. Indeed, this “totipotency,” or the power of the zygote both to generate all the cells of the body and simultaneously to organize those cells into coherent, interacting bodily structures, is the defining feature of the embryo.
This is a key insight into this question of when life begins. Condic further states:
Once a concession has been made to the concept of manufacture and to an arbitrary point at which development has proceeded “far enough” along the assembly line to generate a human being, the precise positioning of this point becomes purely a matter of preference, convenience, and the power to enforce one’s view.
In contrast, if the embryo comes into existence at sperm-egg fusion, a human organism is fully present from the beginning, controlling and directing all of the developmental events that occur throughout life. This view of the embryo is objective, based on the universally accepted scientific method of distinguishing different cell types from each other, and it is consistent with the factual evidence. It is entirely independent of any specific ethical, moral, political, or religious view of human life or of human embryos.
There remains the issue of what rights should be afforded human life at its earliest stages of development. But the scientific question of when life begins has been firmly answered.
