BE COURTEOUS AND TOLERANT
It is almost impossible to estimate the moral effect of a broad-minded, tolerant and courteous attitude toward others engaged in the practise of the healing art. Medical doctors seldom agree, especially those of different schools. They accuse each other of ignorance and incompetence, and the public is sometimes inclined to concede that they are right.
In certainty and in truth one has confidence and strength which is always conducive to tolerance. The food scientist, knowing the laws of cause and effect in regard to nutrition, and knowing the proper use of natural methods of diet and hygiene in the prevention and the cure of specific dis-eases, needs neither to dispute with a fellow practitioner, nor to argue with his patient. He can afford to state his position and quietly allow Nature to prove his claims.
