To begin with, human bodies differ in nature and temperament; compounded as they admittedly are of the same elements, they are yet compounded in different proportions. I am not referring at present to sexual differences; the male body is not the same or alike in different individuals; it differs in temperament and constitution; and from this it results that in different men diseases also differ both in character and in intensity; one man’s body has recuperative power and is susceptible to treatment; another’s is utterly crazy, open to every infection, and without vigour to resist disease. To suppose, then, that all fever, all consumption, lung-disease, or mania, being generically the same, will affect every subject in the same way, is what no sensible, thoughtful, or well-informed person would do; the same disease is easily curable in one man, and not in another. Why, sow the same wheat in various soils, and the results will vary. Let the soil be level, deep, well watered, well sunned, well aired, well ploughed, and the crop will be rich, fat, plentiful. Elevated stony ground will make a difference, no sun another difference, foothills another, and so on. Just so with disease; its soil makes it thrive and spread, or starves it. Now all this quite escapes my father; he makes no inquiries of this sort, but assumes that all mania in every body is the same, and to be treated accordingly.
