Joseph Murphy wrote one of the best-selling self-help books of the twentieth century, and unlike a lot of mid-century bestsellers, it never really went out of print or out of fashion. The Power of Your Subconscious Mind is still commonly handed to people as a first introduction to the idea that inner belief shapes outer circumstance, often by readers who have no idea it was written by an ordained minister in 1963.
From a Cork seminary to a New York pharmacy counter
Murphy was born on May 20, 1898, in Ballydehob, County Cork, Ireland, the son of a headmaster at a private boys’ school, and was raised in a strict Roman Catholic household. As a young man he was accepted as a Jesuit seminarian, training for the priesthood, but grew increasingly uneasy with Catholic orthodoxy and left before ordination.
In 1922 he emigrated to the United States, arriving in New York, where he trained and worked as a pharmacist, a detail that tends to surprise people who only know him as a minister and author. While working the counter, he began studying comparative religion and philosophy more broadly, a period that eventually took him as far as India to study Hindu philosophy directly.
Finding New Thought
Back in New York, Murphy attended the Church of the Healing Christ, part of the Divine Science tradition, where Emmet Fox was minister. Through Fox and through the wider New Thought world he was moving in, Murphy encountered Ernest Holmes, founder of Religious Science, and the writing of Thomas Troward, a retired judge whose lectures on mind and causation influenced a whole generation of New Thought teachers. Both left a visible mark on Murphy’s own thinking.
Murphy went on to be ordained as a New Thought minister and eventually became minister of the Los Angeles Divine Science Church, a position he held from 1949 onward, building it into one of the larger New Thought congregations in the country, with sermons, classes and a radio program that steadily grew his following well before his books did. He also completed further academic study over the years, including a PhD in psychology, and was commonly introduced in later life with both religious and academic credentials attached to his name.
The subconscious as the operative idea
Murphy’s core claim is that the subconscious mind governs a much larger share of health, behavior and circumstance than most people assume, and that it isn’t a discerning judge of truth. It accepts what it’s given. If a thought, especially one repeated with real feeling, is impressed on it consistently enough, the subconscious treats that thought as fact and works, largely outside conscious awareness, to produce outer conditions that match it.
This is why his method centers so heavily on repetition and feeling rather than on effort or willpower. Deciding once, intellectually, that you want something isn’t the same as impressing that desire on the subconscious with enough emotional conviction that it actually takes hold. Murphy taught that the period right before sleep, when the analytical, skeptical conscious mind is naturally quieter, is a particularly effective time to do this deliberately.
He also folded prayer directly into this framework. For Murphy, prayer wasn’t fundamentally different from any other form of directed, repeated suggestion. It was that suggestion addressed inward, toward what he sometimes called the God-power within, rather than a request lobbed outward to a separate deity waiting to grant or withhold favor. This is a distinctly Murphy-specific interpretation of prayer, closer to a psychological technique dressed in devotional language than to how prayer is generally understood across most Christian traditions, and it’s best read as his own framing rather than as a claim about Christian doctrine generally.
A practical, repeatable method
Stripped down, Murphy’s recommended practice is straightforward: state what you want as though it’s already true, in simple, calm, present-tense language, and repeat it with feeling, ideally at a quiet moment such as just before sleep, until it feels natural rather than forced. This is, in effect, a structured, devotional version of affirmations, and it’s the aspect of his teaching that shows up most directly in manifestation content today, even when Murphy’s name doesn’t come with it.
Compared with Neville Goddard
Murphy and Neville Goddard are the two figures most responsible for popularizing the idea that inner conviction, not just circumstance, determines outer results, and both remain heavily cited, often without attribution, in contemporary manifestation writing. Their methods differ in some specific and useful ways.
Goddard’s core technique, SATS, is narrow and sensory: one small, specific imagined scene, held in a relaxed, drowsy state, that implies the goal has already happened. Murphy’s method is broader and more verbal: a stated affirmation, repeated with feeling, closer to devotional practice than to imaginal scene-setting. Their institutional lives diverged just as clearly. Goddard worked as an independent lecturer with no congregation or denomination behind him, while Murphy spent decades as an ordained minister leading an actual church, complete with sermons, membership and a radio ministry. And their language differs too: Goddard leans on Scripture reread as inner psychological drama and on his own specific vocabulary of “assumption” and “the wish fulfilled,” while Murphy leans more on the language of psychology and comparative religion layered over conventional Christian prayer. Both were shaped by the same broader New Thought current and were active in overlapping decades, even though they arrived at their teaching through very different paths.
Where the book still fits
The Power of Your Subconscious Mind was published in 1963, right as the modern self-help publishing category was taking shape, and it has stayed continuously in print since, including newer annotated editions aimed at readers discovering it for the first time. Murphy wrote more than thirty books over his lifetime, among them Riches Are Your Right (1952) and Within You Is the Power (1977), but none approach the reach of his best-known work. Situated within the broader New Thought movement, Murphy represents one of its most commercially successful bridges between devotional Christianity and the mind-power teaching that runs through so much of today’s manifestation writing.
