The 'Needham Question' and Post-War International Science

Key Insight

During his extensive travels, a profound intellectual mystery emerged: why, despite its evident intelligence, inventiveness, and a thousand years of inquiry into the natural world, had China remained comparatively poor and scientifically backward for so long? This question, later known as the 'Needham Question,' vexed him and became a central concern, eventually defining his life's work. This puzzle encapsulated a defining aspect of China and its history.

Shortly after the war, an urgent invitation led him to England to help establish a global scientific organization. He was deemed ideal for setting up the Division of Natural Science for the United Nations Educational, Scientific, and Cultural Organization (UNESCO), a body designed to promote world peace through cultural exchange and scientific cooperation. However, his political leanings, described as 'a good Communist' by a colleague, and his proposed collaborations with Soviet-backed organizations, attracted suspicion from the American administration.

A top-secret CIA memo in February 1947 specifically identified him as the 'principal problem' within UNESCO, warning President Truman of 'grave dangers' if communists occupied strategic scientific posts. Consequently, numerous bureaucratic hurdles were erected, and UNESCO was prevented from funding scientific unions deemed left-wing. In March 1948, he resigned, relieved to return to scholarship away from the 'fratricidal feuding' of the Cold War era. Back in Cambridge, surrounded by his books and his Chinese muse, he committed himself to the monumental task of creating volumes that would properly place China's scientific and technological achievements in the global pantheon.
