This does not mean that the fact of germs should altogether be ignored, for it is not possible to ignore something which you see; besides it does not mean that the discovery of microbes has not been of use to the physicians, enabling them to attend better to the patient. Yet at the same time one can be too sensitive to germs, one can exaggerate the idea of germs, making the idea more than the reality. But one person will be susceptible to those germs and tend to be their victim; while another person assimilates those germs and thus destroys them. In other words, the one is destroyed by germs and the other destroys them.
