William A. Alcott,
Forty Years in the Wilderness of Pills and Powders
“ If honest, must we not acknowledge that, even in the natural history of disease, there is very much doubtful, which is received as sure? And in therapeutics, is it better yet, or worse? Have we judged—have we deduced our results, especially in the last science—from all, or from a selection of facts?"Do we know, for example, in how many instances such a treatment fails, for the one time it succeeds? Do we know how large a proportion of cases would get well without any treatment, compared with those that recover under it? Do not imagine, my dear father, that I am becoming a sceptic in medicine. ”
