There was a wonderful banner at a demonstration a few years ago, on climate: "We come armed only with peer-reviewed science." But actually, that's not true. Unless you come armed also with passion, commitment, care for the future of the human race; unless you're prepared to organize properly; unless you're prepared to use, in other words, all the tools of philosophy and politics and art, it's not going to be good enough. Science alone certainly cannot save us.
