In 1903 Mark Twain wrote of Christian Science: "The power which a man's imagination has over his body to heal it or make it sick is a force which none of us is born without. The first man had it, the last one will possess it." The power of the mind over the body is often indisputable, even among the staunchest defenders of the scientific method. The biologic effect of hope or faith, which scientists sometimes refer to as the placebo effect, is little understood in the medical community.
