Passage: Notably, the most broadly influential innovation of 20th-century American tort law was the rule of strict liability for defective products, which originated with judicial glosses on the law of warranty. In 1963, Roger J. Traynor of the Supreme Court of California threw away legal fictions based on warranties and imposed strict liability for defective products as a matter of public policy in the landmark case of Greenman v. Yuba Power Products. The American Law Institute subsequently adopted a slightly different version of the Greenman rule in Section 402A of the Restatement (Second) of Torts, which was published in 1964 and was very influential throughout the United States. Outside the U.S., the rule was adopted by the European Economic Community in the Product Liability Directive of July 1985 by Australia in July 1992 and by Japan in June 1994.

Passage: In contrast to Catholic allegations of rationalism and naturalism, Protestant objections are more likely to be based on allegations of mysticism, occultism, and even Satanism. Masonic scholar Albert Pike is often quoted (in some cases misquoted) by Protestant anti-Masons as an authority for the position of Masonry on these issues. However, Pike, although undoubtedly learned, was not a spokesman for Freemasonry and was also controversial among Freemasons in general. His writings represented his personal opinion only, and furthermore an opinion grounded in the attitudes and understandings of late 19th century Southern Freemasonry of the USA. Notably, his book carries in the preface a form of disclaimer from his own Grand Lodge. No one voice has ever spoken for the whole of Freemasonry.

Passage: Americans with Sub-Saharan African ancestry for historical reasons: slavery, partus sequitur ventrem, one-eighth law, the one-drop rule of 20th-century legislation, have frequently been classified as black (historically) or African American, even if they have significant European American or Native American ancestry. As slavery became a racial caste, those who were enslaved and others of any African ancestry were classified by what is termed "hypodescent" according to the lower status ethnic group. Many of majority European ancestry and appearance "married white" and assimilated into white society for its social and economic advantages, such as generations of families identified as Melungeons, now generally classified as white but demonstrated genetically to be of European and sub-Saharan African ancestry.
