The thoroughly footnote supporting the latter part of that sentence is supposedly comes from something written by The Massachusetts Medical Society, but actually comes from a speech written by a single physician over half a century before the rise of the AMA's Council on Medical Education. And it does not say that mankind "should be 'looked upon by the mass of mankind with a veneration almost superstitious.', as is stated. It doesn't even get the year of publication of the quote right.
Packing an article with footnotes doesn't mean a damn thing.
Other footnotes include such thorough scholarship as this one time an unnamed Chemistry instructor told me off the record that white men have a harder time getting into med school with mediocre scores than black women do, and editorialized quotes from sources where neither a long enough quote, or enough information on the source is provided to lookup the full quote.
