"I wish to invite you to the consideration of a great principle of Nature—a great natural force that manifests its activities in the phenomena of Dynamic Mentation—a great Something the energies of which I have called MIND-POWER." My thought on the subject is based upon the fundamental conception that THERE EXISTS IN NATURE A DYNAMIC MENTAL PRINCIPLE—A MIND-POWER—PERVADING ALL SPACE—IMMANENT IN ALL THINGS—MANIFESTING IN AN INFINITE VARIETY OF FORMS, DEGREES, AND PHASES. I hold that this energy, or force, or dynamic principle, is no respecter of persons. Its service, like that of the sun and rain, and all natural forces, is open to all—just and unjust; good and bad; high and low; rich and poor. It responds to the proper efforts, no matter by whom exerted, or for what purpose called into effect. But the proper effort must be exerted, consciously or unconsciously, else there will be no operation of the force." - William Walker Atkinson William Walker Atkinson (1862-1932) was a prolific writer. His works treat themes related to the mental world, occultism, divination, psychic reality, and mankind's nature. They constitute a basis for what Atkinson called "New Psychology" or "New Thought".
