An influential strand of Jose Harris’s research has emphasised the importance of idealist political thought to the rise and fall of the British welfare state. Harris argues that the mid-twentieth century demise of political theory about social policy left the welfare state vulnerable because its defenders lacked a philosophical discourse with the depth of idealism. This chapter tests this argument by looking in more detail at a case study from the post-1945 discussion about the welfare state: the debate between the group of socialist social policy academics associated with Richard Titmuss and the neo-liberals at the Institute of Economic Affairs spear-headed by Arthur Seldon. The chapter demonstrates that while the defenders of the Beveridgean welfare state lacked theoretical firepower when confronted by a philosophical counterblast from the right, the major weakness of the left’s social policy analysis was in fact a failure to contest the neo-liberal appropriation of economic theory.
