I was a little dismayed at that point too - but I think the rest of the paragraph clarifies the point well. I think he's talking about a sincere spiritual journey, not "religious people" as commonly encountered. I'm an atheist, but I also think there's a natural "spiritual" instinct that has to do with artfulness, reflection, and transcendence (eg. the attempt to transcend your view of the world as a single individual)
