that their agitation and fears are enough in themselves to cause you to modify your diet). I only kept bread, butter, and milk in the house, all other foods I was obliged to send for, and if I required a dish to be cooked, I first learned how to do it myself and then taught the boy. I had no fixed times for meals, and did not have a table laid, my food always being brought up on a tray; usually I did not interrupt the work I was doing. I deliberately adopted all these precautions because I had become aware by experience of the extraordinary influence suggestion, and other mind influences, such as habit, had in one's selection of food and the amount one ate. During the first two months in conscientiously eating what I wished, as much of it as I wanted and when my appetite demanded food, my desires were very irregular, ranging over meats and fish, (occasionally) chocolate, sweets, cream, cheese, butter, milk, bread, potatoes, oranges, bananas, sugar, etc., but during the final period my desires were much more simple and regular, confining themselves to bread, Gruyère cheese, butter, cream, bananas, potatoes, occasionally milk. During and subsequent to this period I have become convinced that provided you eat your food slowly and follow your appetite, without guidance from any other knowledge whatever, one gets marked preferences for simple foods with increasing health and happiness, the contentment that comes from the inestimably valuable possession of simple desires. "_Comments on the System_:--The great attraction the system has for me is its frank admission that: (1) One knows practically nothing of those chemical processes that occur during digestion. (2) The guidance for the conduct of life afforded by such vague phrases as 'the collective wisdom of mankind' leave one on the most superficial examination in a state of great doubt, to say the least of it. (3) The guidance afforded by the dogmas of science are open to the most disquieting criticism. (_a_) In the prescription of method without a knowledge of the mysteries of digestion. (_b_) In those observations on insufficient standards of mental and physical optimum efficiency, and of short periods of observation based solely on nitrogenous equilibrium and output of work that you have already shown to be fallacious and variable. (_c_) In short, that one can say that none of the physiological dogmas based on chemistry are not open to criticism.
