This piece by Burton J. Bledstein, The Culture of Professionalism, is amazing. My mind was spinning with thoughts about Critical Link 4 and Mette Rudvin's presentation and paper (that I referenced in my submission to the Proceedings). (Many links cite him; here's one of interest.)
He says professionalization is the penultimate triumph of the "Mid-Victorians" exerting control over personal and social life, by circumscribing specific areas of knowledge which bestowed the knowers with a kind of magical power in a vertically-oriented society, always looking up for self-advancement. "The autonomy of a professional person derived from a claim upon powers existing beyond the reach or understanding of ordinary humans" (p. 93-94).
