One problem with globalisation is that bad ideas seem to travel faster than good ones; first there was smearing tomato ketchup on everything; then drinking sugar-soaked cocktails ('Cosmo'-politanism) instead of our traditional whisky soda, and now this idea that we should abandon the poor to their fate in order to protect their dignity.

Here is an entirely banal idea that I think has the potential to change the world: Take evidence seriously. Taking evidence seriously does not mean privileging numbers over all other forms of knowledge - theories, narratives, images. Nor does it mean the kind of radical skepticism that questions everything to the point where no action is possible.

I mean, I think it's a two-way relationship: I think you should not have too much faith in your own rationality. You should not have too much faith in the rationality of, you know, anybody else either. We all learn together about the way the world is, and I think it's a sort of antidote to wishful thinking of all kinds.

It is possible that Modi sees his life as evidence that hard physical work can triumph over every disadvantage, but if so, most of us Indians do not share his faith.
