I've lost any belief I ever had in scientific policy. I don't think you can have scientific policy. I think science is something like weeds, it just grows of its own accord … and if you've got the right atmosphere, the right situation within universities or within places like CSIRO, then it grows and develops of its own accord. And I believe that science is best left to scientists, that you cannot have managers or directors of science, it's got to be carried out and done by people with ideas, people with concepts, people who feel in their bones that they want to go ahead and develop this, that, or the other concept which occurs to them.
