The general public doesn't know and probably doesn't care about punctuated equilibria nor indeed should they, or the greenhouse effect on some other planet - they barely have the ability to cope with the greenhouse effect on their own planet. So I think you have to distinguish between the broad visibility of a scientist when he or she is speaking to a general public and trying to address general issues and the continued position that a scientist may have into the history of a particular subject.
Richard LewontinWhen the wrong question is being asked, it usually turns out to be because the right question is too difficult. Scientists ask questions they can answer. That is, it is often the case that the operations of a science are not a consequence of the problematic of that science, but that the problematic is induced by the available means.
Richard LewontinAs an American I must say I haven't been very encouraged by the way in which the people who run the government in the United States have been listening to those contrary voices. And so long as the power to run the world lies in the hands of people who are quite happy to see it get warmer, or fuel be used more, then would those people who oppose it are crying in the wilderness - that's the real problem.
Richard LewontinAn ecosystem, you can always intervene and change something in it, but there's no way of knowing what all the downstream effects will be or how it might affect the environment. We have such a miserably poor understanding of how the organism develops from its DNA that I would be surprised if we don't get one rude shock after another.
Richard LewontinI assume the same problem exists in Australia as in America of back-biting and jealousy and parochialism among disciplines - there are the scientists, and there are the humanities people, and there are chemists and the physicists and everybody snipes at everybody else and inter-disciplinary communication is rare. But it's very precious and necessary.
