This work on the theory of education was first published in 1839. The five writers had been chosen as the winners in a competition for an essay on the 'Expediency and Means of Elevating the Profession of the Educator in Society', organised by the Central Society of Education, founded in 1837 to promote state funding of education, at a time when the 'monitor' system, whereby older children taught younger ones, was seen as an effective (and money-saving) method. The journalist John Lalor (1814–56) won first prize with a wide-ranging consideration of all the aspects of education, comparing the status of teachers through history and across several countries, and championing their 'sacred mission'. The runners-up were the writer John A. Heraud, the Unitarian minister Edward Higginson, the lawyer and author James Simpson, and Mrs Sarah Porter, prolific writer on education and sister of the political economist David Ricardo.
