I have tried to navigate and understand a world that is extraordinarily complex. The useful skill I possess is an ability to read and process a lot of information quickly: on average, I read around 600 pages of source material for every column I write. But this is nowhere near enough. The world’s complexity, and the impossibility of mastering any subject, let alone of achieving a comprehensive overview, means that we will always be wrong in some respects.
