"Building the Earth": Pierre Teilhard de Chardin, Science, and the Spirituality of the United Nations

During a 1982 trip to Paris, Secretary-General Javier Pérez de Cuéllar raised a glass to toast France's many contributions to the mission of the United Nations. But the Frenchman who received the most fulsome praise from Pérez de Cuéllar was neither an Enlightenment philosopher nor an eminent politician; he was a Jesuit priest and paleontologist by the name of Pierre Teilhard de Chardin. Teilhard had recognized, the Secretary-General explained, that "humanity is undergoing a metamorphosis, a transformation toward a planetary society that is united in its roots and more and more diversified in its component parts and individual lives."¹ And this insight made him "the French philosopher who has had the greatest influence on the metaphysical and planetary evolution of the United Nations."² Pérez de Cuéllar was by no means alone in his thinking. No less than five Secretaries-General have invoked Teilhard de Chardin as a key influence on their own thought and on the mission of the UN.

Why were so many leaders of this ostensibly secular international organization taken with the work of an idiosyncratic Catholic priest-scientist, and what can his story tell us about the role religion has played in postwar projects of global governance more broadly? As its charter makes clear, the United Nations is a secular institution. But in recent years, historians have begun to probe the crucial contributions that religious actors made to the drafting of the Universal Declaration on Human Rights in 1948.³ Others have shown how American ecumenical Protestants such as John Foster Dulles contributed to shaping the creation of the UN by means of a highly successful domestic lobbying campaign.⁴ In both cases, the scholarship has tended to focus on the way religious actors shaped human rights discourse at the UN. For its part, the social-scientific literature on the UN's engagement with religion has tended to emphasize the role of faith-based organizations (religious NGOs), which have proliferated since the 1990s.⁵ Among the most important of these is the Catholic Church, which holds a unique status; as the only religious institution that is also a state, it has been recognized as a permanent observer state since 1964.⁶ What is missing from both the historical and social-scientific literature, however, is an account of the distinctive spirituality of the UN itself. Quite apart from the organization's relationship to religious institutions or the influence of religious actors on human rights activism, how have religious ideas informed the way leading UN diplomats have imagined the institution's mission of global governance?

This article explores this question by examining the reception of Teilhard de Chardin's Catholic cosmology, and especially his account of globalization—or "planetization," as he called it—at the UN. Trained as both a Jesuit priest and a professional geologist and paleontologist, Teilhard elaborated a controversial theory of evolution that encompassed everything from inorganic matter to human life to religious salvation. Teilhard's theory that human life on Earth was converging at both a biological and spiritual level earned him the suspicion of Vatican authorities, but it also found an enthusiastic reception at the highest echelons of the UN Secretariat and at UNESCO. What attracted UN bureaucrats to the Jesuit's worldview was precisely its synthetic ambition—the way it promised to reconcile science and religion—and its account of a pan-human convergence capable of preserving the distinct value of local cultures and individual persons. The fascination with Teilhard at the UN was by no means confined to Catholics, however. If the Jesuit's ideas appealed to both Catholics and non-Catholics, it was precisely because they seemed to transcend their author's Catholicism and point toward a universal spirituality that merged the insights of the great "world religions." This sort of spirituality was exactly what many UN diplomats thought the organization needed to support and animate its mission of global governance. Material forces such as technological innovation and economic markets could only ever yield an "external" form...
