Arthur Seldon (1916-2005) was a significant British neo-liberal economist in the second half of the twentieth century. From 1957 to 1988, as the "engine room" of the Institute of Economic Affairs, Seldon had been advocating the reform of "free" state education. He vigorously argued for education vouchers, by which each parent could be provided with purchasing power and school choice. From the mid-1960s, his ideas gradually attracted the attention of the Conservatives and contributed to the rise of the New Right and Thatcherism in the 1980s. Despite this, previous literature seldom explores Seldon's work in relation to education in greater depth. To fill the lacuna, this paper aims to provide a deeper understanding of Seldon's neo-liberal ideas about education and his approaches in promoting reform agenda.
