Just because somebody is a physicist doesn’t mean that person has any particular understanding of society, or the future, or the way things are going, or any particular authority to discuss such matters. So one has to be careful, saying that because I won the Swedish prize in physics, I can now make a pronouncement on all sorts of political subjects and so on. I think that one has to be very careful of that. But just because one has won the Swedish prize in some scientific subject doesn’t mean that one has to shut up either! It’s just that one shouldn’t abuse, I think, one shouldn’t abuse the privilege excessively in having this sort of title by sounding off on all sorts of things without thinking deeply about them. But if one joins with colleagues from many other walks of life, many disciplines, to think deeply about some important issue facing humanity, and then one says something about it, particularly together with those other people, I think that’s very good, and should be greatly encouraged. But that is quite different. But when one says something, again, it should not, I think, be excessively polemical. It can have a polemical streak to it. Otherwise it might not get much publicity, people may not pay much attention to it. I think that scientists have some responsibility to make more or less responsible statements about things, rather than things that are merely shrill and polemical. And, also, they should initiate wherever possible, together with these colleagues from many other fields, serious discussions and serious research on issues facing the world. Not just off-the-cuff pronouncements. And anyway, that is what I have tried to do. I have tried to help organize such efforts to think deeply about things, together with colleagues from a great many sectors.
