Biography
Biography
Prentice Mulford was born in Sag Harbor, New York, a seafaring village on Long Island, in 1834. He grew up amid tales of distant voyages and maritime adventure. In 1856, at the age of 22, he shipped out aboard the clipper Wizard for San Francisco, California, where he would spend the next 16 years. Life at sea proved to be grueling and unwelcoming, and his initial role cleaning the ship's pig-pen became symbolic of the indignities he endured. Later, aboard the whaling vessel Henry, Mulford worked as cook and steward despite lacking both aptitude and training, a role he eventually came to manage through determination and invention. His humorous reflections on this period express ideas of perseverance and mental power, which he would later incorporate into his New Thought writings. After ten months at sea, Mulford turned to gold mining in California, and spent several years in mining towns, trying to find his fortune in gold, copper, or silver. He worked as a butcher’s assistant, miner, cow-keeper, and schoolteacher. These years of hardship and solitude deeply influenced his thinking, leading him to explore the relationship between the mind and the conditions of life. He became convinced that one's inner state shaped one's outer reality and that mental discipline, rather than external effort alone, was the key to health, success, and fulfillment. After leaving the mining life, Mulford ran for a position on the California State Assembly in Sacramento. Although he was nominated, he ultimately lost the election.
Early literary career
Early literary career
Mulford’s literary career began when he was invited to write for The Golden Era in San Francisco. Although given an opportunity to mingle with major literary figures such as Bret Harte and Mark Twain, his extreme shyness, modesty, and lack of financial planning left him in poverty, with many San Franciscans naming him a "Bohemian" because of his disregard for money. Mulford states in his autobiography, "poverty argued for us possession of more brains" (Prentice Mulford's Story 130). He became known for his humorous style of writing and vivid descriptions of both mining life and life at sea. He joined Joaquin Miller in London in 1872 and edited Miller's breakout bestseller, Life Among the Modocs. Mulford later worked as a newspaper editor and contributor. He was assigned to Europe to report on international exhibitions, and in London he married a young English woman who was Catholic. In 1872, Mulford returned to New York City, where he became known as a comic lecturer, a poet and essayist, and a columnist for the New York Daily Graphic from 1875 to 1881.

Legacy and Philosophy
His principal legacy was established in the 1880s when he retired to a small self-built cabin in New Jersey and began writing the essays that would become the White Cross Library. These writings formed the basis of his influence on the New Thought movement. In them, Mulford promoted a philosophy centered on self-realization, health through mental harmony, and the transformative power of thought. He advocated for personal spiritual authority, claiming that individuals must draw their wisdom directly from a divine source rather than books or intermediaries. His themes included the higher love of self, divine economy in giving and receiving energy, and the idea that the human soul evolves through many physical lifetimes toward perfection. Mulford rejected religious dogma and emphasized a form of mystical optimism. He claimed that true prayer was a forceful, silent demand directed by will and intention. He believed that mental attitude directly shaped external circumstances, including physical health and financial condition, although he repeatedly acknowledged that his own life did not reflect prosperity in a material sense. His work often warned readers to "demand first wisdom so as to know what to ask for." Mulford emphasized that each individual has direct access to spiritual wisdom without the need for institutional religion or fixed doctrine. He believed that personal experience, intuition, and inner conviction were more reliable than inherited beliefs or formal study. Among his core teachings were the great significance of the creative power of thought, the moral and practical value of optimism, the importance of aligning oneself with natural and spiritual law, and the evolutionary development of the soul through successive lifetimes.

De zwijgende kracht
Influence on the "New Thought" movement
His influence extended beyond his lifetime, shaping the work of key New Thought figures in the early twentieth century. Dr. Herbert A. Parkyn, in developing his system of suggestive therapeutics, drew on principles Mulford had articulated decades earlier concerning the role of thought in health and self-transformation. William Walker Atkinson, another major proponent of mental science, dedicated his first book to Mulford, signaling the deep impact Mulford’s writings had on the formation of New Thought psychology and its applications in personal development and metaphysical healing. Mulford's book Thoughts are Things served as a guide to this new belief system and is still popular today.
