When a wealthy individual seeks to leave a legacy through scientific philanthropy, researchers usually greet such generosity enthusiastically. But the death of investment mogul John Templeton marks an unusual, and notable, exception. At the time of his passing last week, Templeton had poured some US$1.5 billion into the John Templeton Foundation, which funds research at the intersection of science and spirituality. Critics have maintained that the foundation needlessly conflates science and faith, with some calling for an outright boycott of Templeton funding.

Templeton was a deeply spiritual, albeit unorthodox, individual (see page 290). He lived a life firmly rooted in the Christian traditions of modesty and charity. Yet he was also a great admirer of science, the undogmatic practice of which he believed led to intellectual humility. His love of science and his God led him to form his foundation in 1987 on the basis that a mutual dialogue might enrich the understanding of both.

Templeton believed institutional religion to be antiquated, and hoped a dialogue with researchers might bring about advances in theological thinking.

This publication would turn away from religion in seeking explanations for how the world works, and believes that science is likely to go further in explaining human moral impulses than some religious people will welcome. Thus it shares a degree of suspicion with many in the scientific community at any attempt by religiously driven organizations to fund science. A chief concern is that the influential Templeton Foundation might be seeking to inject religion into the scientific world. And it is easy to understand that concern given the political activism of many American fundamentalists and their efforts to promote ideas such as intelligent design, which posits a divine hand in evolution. The foundation's most vigorous critics accuse it of attempting to lace science with spiritualism.

That claim is somewhat ironic, as Templeton himself seemed to have just the opposite in mind. He believed institutional religion to be antiquated, and hoped a dialogue with researchers might bring about advances in theological thinking. The foundation's substantial funding of science and religion departments around the world is directed towards those ends. Theologians have also used foundation money to develop and promote arguments that reconcile some of the apparent contradictions between science and religion. For those many scientists with a faith, promoting the compatibility of science with faith is a prudent and even necessary goal. Strict atheists may deplore such activities, but they can happily ignore them too.

The foundation's scientific agenda addresses 'big questions', which has sometimes resulted in work that many researchers regard as scientifically marginal. One field popular with the foundation is positive psychology, which seeks to gauge the effects of positive thinking on patients, and which critics argue has yielded little. Also heavily supported are cosmological studies into the existence of multiple universes — a notion frequently criticized for lying at the edge of falsifiability. The concern is that such research has been unduly elevated by the foundation's backing. But whatever one thinks of positive psychology and the like, the foundation's support has not taken anything away from conventional funding. And in the field of cosmology at least, it has arguably yielded some new and interesting ideas.

The foundation's management now falls chiefly to Templeton's son, John M. Templeton Jr, whose Christian beliefs are reportedly much more conventional than his father's. A critical scrutiny of the foundation's scientific influence continues to be warranted, and no scientific organization should accept sums of money so large that its mission could be perceived as being swayed by religious or spiritual considerations. But critics' total opposition to the Templeton Foundation's unusual mix of science and spirituality is unwarranted.
