Nature requires no sacrifices and imposes no penalties for obeying her beneficent demands. Natural Laws are easily comprehended if studied objectively. Ill health, inharmony and unhappiness come only from disobeying Nature. God (obeyed) is Only Good. NATURE STUDY Nature cannot be profitably studied alone through books. Nature has a separate message for each intelligence. Each body machine has peculiarities which the possessor alone can understand. Object lessons, personally experienced or observed, are the best. "Once seeing (or feeling) is worth an hundred times telling about," is a wise Japanese proverb; and it is true. As the swinging pendulum taught Galileo, and the falling apple suggested to Sir Isaac Newton, the law of gravity, in like manner the modern electric power-plant teaches us, by analogies, suggestions useful in the study of ourselves--our own Mind Power-Plant. OLD AND NEW THE OLD IDEAS The old religion condemned man, even though unenlightened, to perdition and saved him only through special dispensation. The old education insisted on narrow formulas and tried to cram all mentality into prescribed moulds. The old physiology presupposed disease and glorified pathology. THE NEW STUDY The new religion glorifies Love, stimulates Appreciation and preaches only Optimism. The new pedagogy aims to discover the useful tendency with which each creature is equipped at birth and to cultivate this God-given inclination as designed by the Creator. The new physiology studies Hygiene and assists Nature by securing Prevention to avoid the necessity of correction and cure. SAFE HYPOTHESES Assuming that Nature's intentions are only right, ill-health is unnatural. If Nature's invitations, as expressed by Normal Appetite, are rightly interpreted, good health must result. When there is bad health Nature has been disobeyed. A REASONABLE CONCLUSION If Physiology has failed to teach a way to maintain perfect health some of her hypotheses must be wrong. If any of the hypotheses of Physiology are discredited any one of them may be doubted.[5] [Footnote 5: Since this was written, the then accepted standards of human food requirements have not only been questioned but have been discredited and disproved. The great importance of mouth-work in the economics of digestion has been demonstrated and accepted.] OUR NATURAL GUARDIANS THE SENSES GUIDING SUPPOSITIONS The stomach and other hidden parts of the body have automatic functions independent of the will that perform digestion; these functions are beyond the scope of control, and hence means of preventing ill-digestion must be studied by the aid of the exterior sensations. Sight, Appetite, Touch and Taste are the senses useful in selection of food and in the prevention of indigestion. Sight and Appetite relate to invitation and selection, while Touch and Taste are discriminators and indicators of conditions.
