At a time when science can seem complex and remote, it has a greater impact on our lives, and to the future of our planet, than ever before. It really matters that its discoveries and truths should be clearly and widely communicated. That its enemies, from the malicious to the muddled, the self-deluding to the self-interested, be challenged and exposed. That science should be brought out of the laboratory, taken into the corridors of power and defended in the maelstrom of popular culture. No one does this better than Richard Dawkins.
