There is no question about the necessary and beneficial action of the bacteria that are in us and about us all the time. The germs that infest our bodies, our food, our atmosphere, our soil, are necessary to our existence. If they were not, they would not be there. Nature never stultifies herself; there is a reason for everything, and that reason is backed by the logic of the Absolute.
The weakest point in modern medical science is its teachings on bacteriology. It teaches that germs cause disease. If that could be proved, it would establish demonology, and chaos would reign supreme. Good and bad entities cannot exist in the same universe. Good, when ill-used, is made less good; but good is a state, and all states fluctuate from what we call good to what we call bad. The two extremes, however, are two points of view of the same state. There is no room for bad, except as a figure of speech with which to measure or contrast degrees of good. There is no disease per se--only different degrees of health. There is no bad per se--only different degrees of good.
Germs, food, sunshine, air, all the elements, are friends or foes to man. They are his health or his disease, depending entirely upon how they are used.
Germs are as necessary as water. If we are deprived of water, we soon die; if we are submerged into water, we die quickly; if deprived of a reasonable amount of germs, we are made sick, or, if infested with too many, we are made sick or die.
