"The problems we face today cannot be solved without alliances," he said. "And alliances won't work without common values."
Blair says his experience at Yale has strengthen his belief that religious, economic, and social globalization are linked.
Multicultural and multi-religious societies are the result of "pushing people together," and now "spiritual capital" and "human capital" need to be linked, he argued.
"Unless we find a way of reconciling faith and globalization, the world will be a more dangerous place," Blair said, according to The Associated Press.
Blair, who was an Anglican Christian, converted to Catholicism in 2007 after stepping down as prime minister of Britain. The former British prime minister will continue to teach at Yale for the next two years as part of a three year partnership between the university and his London-based Tony Blair Faith Foundation. Blair said Yale will be the headquarters for the U.S. operations of his foundation, according to the Yale Daily News.
