"[Science] has no real agenda. What I mean by this is that by its very nature science cannot be forced in any particular direction. The necessarily open nature of science (notwithstanding the secret work carried out in the Cold War and in some commercial laboratories) ensures that there can only ever be a democracy of intellect in this, perhaps the most important of human activities. What is encouraging about science is that it is not only powerful as a way of discovering things, politically important things as well as intellectually stimulating things, but it has now become important as metaphor. To succeed, to progress, the world must be open, endlessly modifiable, unprejudiced. Science thus has a moral authority as well as an intellectual authority."
