Agreed, but that train left the station in the late 1800s, driven by Darwin and Nietzsche. The intervening one and a half centuries haven't dislodged the "human spirit" in its secular form. We thought we'd overcome "gods". Now, out of discontent and self-loathing we're going to do what Freud warned against, and find a new external something to subjugate ourselves to. We simply refuse to shoulder the burden of being free.
