Found an article that gives some details to what I posted:
Blackstone out/Darwin in: The case-law approach, studying judges decisions rather than the Constitution, is now practiced and taught to all aspiring law students.
Blackstone’s Commentaries on the Law, the foundational texts on common law, revealed and eternal law, were discarded as outdated, since it taught that certain rights and wrongs never changed - particularly those related to human behavior. How influential was the study of Blackstone on the moral development and spiritual health of prospective lawyers? So infused with biblical teaching were Blackstone’s books and teachings on the common law, that law students, as a direct result of studying Blackstone’s Commentaries, came to a saving faith in Jesus Christ.
Biblical absolutes permeated American Law up until 1870, when sadly Harvard’s president, Charles Eliot, introduced Darwin’s evolutionary view of the law, selecting Christopher Langdell to guide the prestigious law school to teach relativism, which became known as positive law.
also:
...the beginning of judicial activism – legislating new laws (instead of interpreting law) as a result of their progressive view of the constitution as a “living document” in need of continually changing with the times, according to the Darwinian principle of evolutionary stream of law.
Do you have any links for those?
