This chapter explores the ideological roots of the non-governmental aid. It does so by framing the NGO sector’s attitude to poverty in terms of a worldview that developed in the late nineteenth century – rooted in the concepts of universalism, rational authority, progress and world citizenship. The core narrative element of this chapter focuses on the influence of ‘basic needs’, the highly influential model of rural development adopted by the World Bank in the 1970s, that facilitated the sector’s integration into the international development and emergency relief industries over the following decade. Basic needs was in many ways the perfect catalyst for NGOs. Its focus on ‘absolute poverty’ and on village-level interventions in health, education and economic development – precisely the areas where NGOs operated – transformed the territory of intervention in the Third World. But its influence can only be fully understood by reading the sector’s rapid integration into the development industry in terms of the ideological convergence that underpinned that process. This helps to explain why those organisations and their supporters were simultaneously committed to development and highly critical of the inequalities that underpinned global poverty; their criticisms were born from a genuine belief in those values, and in the need for reform, rather than in the desire for their replacement.
