Planning for a new progressive world after the 1939–45 war led to numerous discussions on reforms at home and programmes for international aid and enlightenment. Eliot's familiarity with these subjects arose from meetings and deliberations with religious, cultural, and educational leaders, and from knowledge of extensive projects for post-war reconstruction. His Notes towards the Definition of Culture (1948) is the product of reflections that began to take shape in 1943. Tending towards the abstract and philosophical, he sees principles and problems rather than their solution; the key word in his title (as it first appeared) is uncapitalized. He is more coherently constructive in the appendix of 1946 broadcast talks to Germany than elsewhere in the volume. The work could be regarded as cautionary, an attempt to ensure that politicians and zealots anticipated problems before reaching conclusions on ameliorative measures. Culture cannot be organized; its growth depends on favourable conditions, and the question is how to make varying conditions favourable.
