Because it is central to the operation of various other requirements, — Roe v. Wade

"As a nation today, we have not rejected the sanctity of human life. The American people have not had an opportunity to express their view on the sanctity of human life in the unborn. I am convinced that Americans do not want to play God with the value of human life. It is not for us to decide who is worthy to live and who is not. Even the Supreme Courts opinion in Roe v. Wade did not explicitly reject the traditional American idea of intrinsic worth and value in all human life; it simply dodged this issue."

"The fact that a majority of the States reflecting, after all, the majority sentiment in those States, have had restrictions on abortions for at least a century is a strong indication, it seems to me, that the asserted right to an abortion is not ‘so rooted in the traditions and conscience of our people as to be ranked as fundamental...’"

"This right of privacy... is broad enough to encompass a womans decision whether or not to terminate her pregnancy....[T]he word person, as used in the 14th Amendment, does not include the unborn."

"Several decisions of this Court make clear that freedom of personal choice in matters of marriage and family life is one of the liberties protected by the Due Process Clause of the Fourteenth Amendment. . . . That right necessarily includes the right of a woman to decide whether or not to terminate her pregnancy."

"Presumably, therefore those women who qualify for a legal abortion according to the terms of the statute should be able to obtain one, regardless of their race or socio-economic status. There is nothing demonstrable in the differences of skin color or economic condition which suggests that a substantially smaller proportion of the poor or the non-white fall into this category than that of the white and the non-poor, or that the poor and non-white have a substantially different moral attitude on abortion. On the contrary, a recent study of births occurring between 1960 and 1965 led investigators to conclude that one-third of Negro (as contrasted with one-fifth of white) births were unwanted. Unwanted births were in general more than twice as high for families with incomes of less than $3,000 as for those with incomes of over $10,000; this differential was "particularly marked among Negroes." The results indicated, in the view of the investigators, that there is a "coincidence of poverty and unwanted births rather than a propensity of the ‘poor’ to have unwanted children." One explanation for this high level of unwanted births among the poor and the non-white is surely the fact that they do not have equal access to abortions. Data demonstrate that the poor and the non-white do not receive this medical treatment on the same terms as do others. They thus suffer a particularly harsh and adverse effect from the operation of this statute, as they do from that of the other restrictive abortion laws which have existed and currently exist in the United States...."

"On another level as well, abortion is a safe procedure: it is without clinically significant psychiatric sequelae. A number of recent studies confirm that abortion does not produce serious psychological side-effects damaging to the mental wellbeing of the patient."
