Science is divine: it is neither of human origin nor of human direction. That which is termed “natural science,” the evidences whereof are taken in by the five personal senses, presents but a finite, feeble sense of the infinite law of God; which law is written on the heart, received through the affections, spiritually understood, and demonstrated in our lives.
This law of God is the Science of mental healing, spiritually discerned, understood, and obeyed. (Eddy, Mary Baker, Miscellaneous Writings, p.172:16-24)
