Yeah, I get that antidote to the various secular and scientistic conceits of hyperrationality from David Hume and the existential philosophers. Cognitive science has confirmed that perspective (that our inherent capacity for reason is a "slave to the passions").
I've written against Haidt, though, since he's one of those conniving, opportunistic centrists who tries to make conservatism look respectable. On his view, conservatism is more balanced than liberalism in terms of the added values or instincts it encompasses. See my article below on the conservative's misunderstanding of liberty.
