Scientists are educated from a very early time and a very early age to believe that the greater scientist is the scientist who makes discoveries or theories that apply to the greatest ambit of things in the world. And if you've only made a very good theory about snails, or a very good theory about some planets but not about the universe as a whole, or about all the history of humankind, then you have in some sense accepted a lower position in the hierarchy of the fame of science as it's taught to you as a young student.
Richard LewontinThe 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 LewontinPeople who have various kinds of politics for whom it is congenial for their apriority politics to say yes, things are getting much worse. They are opposed by people who also have a priori politics saying that this is the best of all possible worlds, capitalism is the greatest thing since sliced bread and you're just alarmists and so on and they can massage the data so it fits them.
Richard LewontinIf we're going to make a politically responsible and a scientifically sensible claim it should not be stop the world exactly where it is because that's not possible. It has to be to decide what kind of world do we as human beings want to live in.
Richard LewontinThe social scientist is in a difficult, if not impossible position. On the one hand there is the temptation to see all of society as one's autobiography writ large, surely not the path to general truth. On the other hand, there is the attempt to be general and objective by pretending that one knows nothing about the experience of being human, forcing the investigator to pretend that people usually know and tell the truth about important issues, when we all know from our own lives how impossible that is.
Richard LewontinIf I ask you who is the most famous scientist who ever lived, or the greatest scientist who ever lived you'll say either Einstein or Newton or something like that because their claims were supposed to apply universally. But the claim of somebody who is studying a particular feature of the evolutionary process like whether it's very fast or very slow, or occurs in steps and so on, that's not a universal claim, that's a rather specialised claim and so you can't claim to great fame and great success.
Richard LewontinHistory has got a lot to do with unique circumstances under certain particular cases and grand theories will always find counter cases. I don't think that people whose expertise lies in one thing should try to make grand theories about something (a) where it's very hard to get the evidence to prove that you're right and (b) where it's much too easy to make up stories that seem right.
