The sharp separation between religion and reason in public life is not compatible with democracy. For thinkers like Habermas this separation is based upon enlightenment, but in fact it is based only on one version of enlightenment, that of Kant. If we turn instead to Hume, who made feeling, not reason, central for the workings of the human mind, then we discover far more fluidity between religious and other modes of thought and yet at the same time a greater ease with naturalism. Moreover, when we understand the centrality of feeling for thought, modes of physicalist reductionism of mind become much harder to entertain, even within a naturalistic perspective.
