Contempt prior to investigation
In what AA literature and page is this phrase found?
It was originally a quote that prefaced a personal story entitled An Artist's Concept
in the First Edition of the Big Book. In later Editions it is found in the appendixes at the end of Spiritual Experience.
You should note however that the attributed author (Herbert Spencer) likely never said or wrote it.
This quotation seems to have evolved in the course of numerous attributions to an observation written by British theologian William Paley. In his work A View of the Evidences of Christianity of 1794, Paley wrote:
The infidelity of the Gentile world, and that more especially of men of the 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.
