Earlier Bill Wilson had been advised by Dr Silkworth to change his approach and tell the alcoholics they suffered from an illness, one that could kill them, and afterward apply the Oxford Practices. The idea that alcoholism was an illness, not a moral failing, was different from the Oxford concept that drinking was a sin. This is what he brought to Bob Smith on their first meeting. Smith was the first alcoholic Wilson helped to sobriety. Dr. Bob and Bill W., as they were later called, went on to found Alcoholics Anonymous.
