In religious belief as elsewhere, we must take our chances, recognizing that we could be wrong, dreadfully wrong. There are no guarantees; the religious life is a venture; foolish and debilitating error is a permanent possibility. (If we can be wrong, however, we can also be right.)

Suppose we concede that if I had been born of Muslim parents in Morocco rather than Christian parents in Michigan, my beliefs would be quite different. [But] the same goes for the pluralist...If the pluralist had been born in [Morocco] he probably wouldn't be a pluralist. Does it follow that...his pluralist beliefs are produced in him by an unreliable belief-producing process?

There is superficial conflict but deep concord between science and theistic religion, but superficial concord and deep conflict between science and naturalism
