Henry Lord Brougham (1778-1868) belongs with Thomas Jefferson and Horace Mann in the United States and Egerton Ryerson in Canada as one of the great promoters and founders of public education in the English-speaking world. His most famous phrase is The schoolmaster is abroad and this quote symbolizes his belief that the fate of the modern, liberal society depends on free access to education for the population at large. It is not that Brougham any more than Jefferson failed to draw a distinction between the education that was fitted for the gifted few and that suited to the general public whose lives would lack the leisure for intellectual pursuits of the highest difficulty and training. Rather it is that Brougham adheres to a philosophy of enlightenment which sees the interests of science and society as ultimately indistinguishable and which insists that the spread of knowledge about both the natural and social worlds carries with it no price in terms of individual or social morality. This paper gives an overview of Brougham's philosophy of public enlightenment including his views on the example of Benjamin Franklin. It then reviews the attacks on this philosophy from the Anglican point of view in the form of the Reverend E.W. Grinfield's A Reply to Mr. Brougham's Practical Observations upon the Education of the People and from the Roman Catholic point of view in Cardinal Newman's famous Tamworth Reading Room and Discourse on University Education.
