This week, a guest post. Jack, your temporary author, writes: ‘Paul’s been a friend of mine since school, but he lives in a fantasy world. Banging on about how great it’d be if we constructed a new world with our conscious choices overlooks that despite many having dreamed of doing such a thing, as far as I – and I suspect you – can tell, no bugger’s actually done so. Dreaming doesn’t pay the rent. Paul’s writing an entire book about seeing reality more clearly, while bafflingly talking of a worldview that matches the reality of precisely zero people’s practical, lived existence. So I offered to treat you to a dose of something far more sensible.’
