A native of Ireland who resettled in America, JOSEPH MURPHY, Ph.D., D.D. (1898–1981) was a prolific and widely admired New Thought minister and writer, best known for his metaphysical classic, The Power of Your Subconscious Mind, an international bestseller since it first appeared on the self-help scene in 1963. A popular speaker, Murphy lectured on both American coasts and in Europe, Asia, and South Africa. His many books and pamphlets on the autosuggestive and metaphysical faculties of the human mind have entered multiple editions. Murphy is considered one of the pioneering voices of affirmative-thinking philosophy.
