Animal magnetism is the unification of mental falsities manifested by humanity as the belief of mind, selfhood in matter. Fear is faith in evil. Courage is faith in good. Doubt is trust in evil. Confidence rightly directed is reliance, is trust in God, good. God is the only cause. Spirit is the only substance. Love is the only force. Harmony is the only law. Now is the only time. Mary Baker Eddy (Carpenter, Gilbert, Essays On Christian Science, p.53)
