As I introduced the incoming students studying religion and theology this year, the key value I hope they learn is cognative empathy, that ability to step into the shoes of another and really understand their disposition. Reading others well, especially those we disagree with, is crucial to this habit. It seems to me that the humanities are about training students in the habits of the mind which underwrite civil society. They provide the historical, literary and cultural understanding to examine and interrogate the human condition.
To use another analogy, one of the great challenges in physics today is to develop a theory which can account for newtonian and quantum mechanics together. "God does not play with dice," Einstein quipped, at the rather probabilistic whacky-ness of the quantum view of reality. The challenge can also be summed up as the relationship between two forces. While gravity is a weak force which nonetheless orders planetary movements, the atomic forces which quantum mechanics accounts for are incredibly strong. The world that seems solid and stable to us is actually mostly empty space held together by atomic forces, electrons, neutrons, etc. The analogy is that whereas the STEM subjects seem to be rather strong forces building, healing and creating, the humanities function like weak gravity. Cultural and religious understanding, the ability to empathise with the positions of others, is a weak force. However, our everyday sense of decency in civil society utterly depends upon it.
As so many recent philosophers have understood, the enlightenment values which undergird democratic societies are fragile. The so-called postmodern critique of the likes of Derrida were meant to call our attention to this fragility, not undermine it.
