Artigas, a professor of philosophy of nature and of sciences at the University of Navarre, spoke with ZENIT.

Q: The title "The Frontiers of Evolutionism" indicates that there are questions that fall outside the competence of science, yes?

Artigas: I will respond with the words of Stephen Jay Gould, one of the most important evolutionists of the 20th century. He was a professor of Harvard University for most of his life.

Let me begin, then, with a personal story.

I was walking through a particularly beautiful village in the mountains of Morocco, some years ago, and I was chatting with my twenty-something guide, a very talkative young man who seemed unusually eager to find out as much about me as he could.

“Are you American?” He asked, right off the bat. “Yes,” I said. “Are you Christian?” “Yes” again, I answered. “Are you Protestant?” Once again I said “Yes.”

What is the church? Whatever else may be said in answer to that question, and whatever may be disputed between the churches, we must surely say at least this: The church is the community of the new covenant between God and humanity that is grounded in the self-offering of Jesus Christ and confesses him as Lord.

In this accessible intellectual history, McGrath explores how atheism came to capture a wide swath of the public imagination as the road to human liberation and progress, and why, in a postmodern world, its appeal has faded. Yet he also makes clear that, despite the resurgence in faith, Western Christianity has not fully recovered from the crisis of the '60s.
