Commonly attributed to Spencer, information provided in The Quote Verifier: Who Said What, Where, and When (2006) by Ralph Keyes and The Survival of a Fitting Quotation. (2005) by Michael StGeorge http://anonpress.org/spencer/, indicates the attribution may have originated with the book [w:The_Big_Book_(Alcoholics_Anonymous)|Alcoholics Anonymous]]. It was used exactly as written above in the personal stories section of the first edition in 1939 and in 'Appendix II: Spiritual Experience' of all subsequent editions.
: "Contempt prior to examination" was a phrase used by William Paley, the 18th-century English Christian apologist. In A View of the Evidences of Christianity (1794), he wrote:
::The infidelity of the Gentile world, and that more especially of men of rank and learning in it, is resolved into a principle which, in my judgment, will account for the inefficacy of any argument, or any evidence whatever, viz. contempt prior to examination.
:Paley's characterization of non-believers was later modified and used by other religious authors who uniformly attributed their words to Paley. In Anglo-Israel or, The British Nation: The lost Tribes of Israel (1879), Rev. William H. Poole may have been the first to render the quotation in its more familiar and enduring form:
::There is a principle which is a bar against all information, which is proof against all argument, and which cannot fail to keep a man in everlasting ignorance. This principle is, contempt prior to examination.
:Various authors following Rev. Poole would offer new iterations of the quotation into the early decades of the 20th century. Most of these credited William Paley, but by the early 1930s the first obscure publications to falsely attribute this quote to Spencer emerged. Its usage for decades since as a maxim in Alcoholics Anonymous and the twelve-step recovery community has popularized its erroneous association with Herbert Spencer.
