"[I]n thinking about how to resolve Roe, Brennan was then in the process of constructing a systematic framework for the ”fundamental freedoms” that he deemed within the meaning of “liberty.” He viewed the first of three groups of such freedoms as including “freedom from bodily restraint or inspection, freedom to do with one’s body as one likes, and freedom to care for one’s health and person.” For these, he cited Terry v. Ohio, Meyer v. Nebraska, and Jacobson v. Massachusetts, among others. The second group included “freedom of choice in the basic decisions of life, such as marriage, divorce, procreation, contraception, and the education and upbringing of children.” Here he relied on Living v. Virginia, Boddie v. Connecticut, Skinner v. Oklahoma, Eisenstadt v. Baird, Griswold v. Connecticut, and others. The third group included “autonomous control over the development and expression of one’s intellect and personality.” The precedent for this last group was thinner. Brennan cited only Stanley v. Georgia (protecting the possession of obscene materials in the home) and Justice Brandeis’s reference in Olmstead v. United States to a “right to be let alone.” Brennan thought that the decision to have an abortion “obviously fits directly within each of the categories of fundamental freedoms,” and therefore “should be held to involve a basic individual right.” Brennan described this framework in a memo he wrote to Justice Douglas about Roe on December 30, 1971."
