The Constitution of Man

One of Gall’s converts was a Scottish lawyer named George Combe. On October 8, 1838, Mann wrote in his diary that he had met "the author of that extraordinary book, The Constitution of Man, the doctrines of which will work the same change in metaphysical science that Lord Bacon wrought in natural." The book was Combe’s. Suddenly the Mann project to downgrade reading acquired a psychological leg to accompany the political, social, economic, and religious legs it already possessed. Unlike other arguments against enlightenment of ordinary people—all of which invoked one or another form of class interest—what psychological phrenology offered was a scientific argument based on the supposed best interests of the child. Thus a potent weapon fell into pedagogy’s hands which would not be surrendered after phrenology was discredited. If one psychology could not convince, another might. By appearing to avoid any argument from special interest, the scientific case took the matter of who should learn what out of the sphere of partisan politics into a loftier realm of altruism.
