But if you are right and that is what he thinks then he IS missing the point. The point in question being that human beings are not purely rational creatures but have a complex inner life that has needs beyond what rationality alone offers. And your linked article rather tends to confirm it: it is just more of the same, considering human beings as citizens and thinking only about engineering social morality and group outcomes, rather than the inner personal needs of the individual human psyche.
To that end, he may simply see that our individual needs can be met, without having to bring religion or spirituality into it. He seems a bit obsessed, though.
