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.
Appetite and Taste are the sense functions that are most important to health, and hence they are the most important to study and understand. They are the guide in nutrition and the guard of the body machine—the Mind Power-Plant.
Smell also is an important aid in selection and discrimination and is an effective assistant of Appetite.
APPETITE AND TASTE ANALYSED
Appetite should be dignified and recognised as a distinct sense.
Normal Appetite is Nature's means of indicating her fuel and repair requirements for the Mind Power-Plant.
Study Normal Appetite and heed its invitation. It prescribes wisely. Its mark of distinction, to differentiate it from False Appetite, is "watering of the mouth" for some particular thing.
False Appetite is an indefinite craving for something, anything! to smother disagreeable sensations and frequently is expressed by the symptom of "faintness" or "All-gone-ness." [Vide the "A.B.-Z. of Our Own Nutrition.">[
Taste is the chemist of the body; of the Mind Power-Plant. More correctly, perhaps, it is the report of a chemical process relating to nutrition.
