Ernest Holmes (1887-1960) was an American writer, lecturer, spiritual teacher, and founder of the Religious Science movement, later widely associated with the Science of Mind tradition. Born in Lincoln, Maine, Holmes grew up with limited formal schooling but developed a wide-ranging intellectual and spiritual curiosity. He read deeply in philosophy, psychology, religion, metaphysics, mental healing, New Thought, Transcendentalism, and comparative spiritual traditions, eventually shaping these influences into a practical philosophy of spiritual law and conscious creation.Holmes taught that the universe is governed by an intelligent creative principle and that human thought participates in that principle. His central message was that people could change their experience by changing consciousness, not through wishful thinking alone, but through disciplined belief, affirmative prayer, spiritual understanding, and alignment with what he saw as universal law. His work appealed to readers looking for a religion of practical results, inner growth, healing, prosperity, confidence, and a direct relationship with divine creative [...] major books include Creative Mind, Creative Mind and Success, The Science of Mind, This Thing Called You, The Art of Life, and many lectures, essays, and lessons that helped define twentieth-century metaphysical religion. Holmes's influence continues through Centers for Spiritual Living and through the broader world of New Thought, manifestation teaching, affirmative prayer, and spiritual self-development. His writings remain important for readers who want a classic source for the belief that consciousness, faith, and imagination are active forces in shaping life.
