但这正是问题，反驳了伊莎贝尔。我们都被同样疲倦和值得信赖的想法所困。如果我们拒绝接受根本不同的可能性，那么我们永远不会取得任何进步。我们仍然认为太阳旋转着地球。
(But that's exactly the problem, retorted Isabel. We're all stuck with the same tired and trusted ideas. If we refused to entertain the possibility of something radically different, then we'd never make any progress - ever. We'd still be thinking that the sun revolved round the earth.)
