"The first eight Amendments to the Constitution have been made applicable to the States only in part. My view has been that, when the Fourteenth Amendment was adopted, its Due Process Clause incorporated all of those Amendments. See Adamson v. California, 332 U. S. 46, 332 U. S. 68 (dissenting opinion). Although the history of the Fourteenth Amendment may not be conclusive, the words "due process" acquired specific meaning from Anglo-American experience. [Footnote 2/7] As MR. JUSTICE BRENNAN recently stated, "The Bill of Rights is the primary source of expressed information as to what is meant by constitutional liberty. The safeguards enshrined in it are deeply etched in the foundations of America's freedoms." The Bill of Rights and the States (1961), 36 N.Y.U.L.Rev. 761, 776. When the Framers wrote the Bill of Rights, they enshrined in the form of constitutional guarantees those rights -- in part substantive, in part procedural -- which experience indicated were indispensable to a free society. Some would disagree as to their importance; the debate concerning them did indeed start before their adoption and has continued to this day. Yet the constitutional conception of "due process" must, in my view, include them all until and unless there are amendments that remove them."
