Woods Hutchinson,
Preventable Diseases
“ The essence of disease consists, not in either the kind or the degree of the process concerned, but only in its [Pg 14] relations to the general balance of activities of the organism, to its "resulting in discomfort, inefficiency, or danger," as one of our best-known definitions has it. Disease, then, is not absolute, but purely relative; there is no single tissue-change, no group even of changes or of symptoms, of which we can say, "This is essentially morbid, this is everywhere and at all times disease." ”
