What are the facts? Again and again and again – what are the facts? Shun wishful thinking, ignore divine revelation, forget what the stars foretell, avoid opinion, care not what the neighbors think, never mind the unguessable verdict of history – what are the facts, and to how many decimal places? You pilot always into an unknown future; facts are your single clue. Get the facts!
