Now, what I want is, facts. Teach these boys and girls nothing but Facts. Facts alone are wanted in life. Plant nothing else, and root out everything else. You can only form the minds of reasoning animals upon Facts: nothing else will ever be of any service to them. This is the principle on which I bring up my own children, and this is the principle on which I bring up these children. Stick to Facts, sir!
A writer need not devour a whole sheep in order to know what mutton tastes like, but he must at least eat a chop. Unless he gets his facts right, his imagination will lead him into all kinds of nonsense, and the facts he is most likely to get right are the facts of his own experience.
Here you have learned the theories of life, " continued the Headmaster, resuming the thread of his discourse, "but after all, life is not a matter of theories. Life is a matter of facts. It calls on the young and the old alike to face these facts, even though they are hard and sometimes unpleasant. Your problem, for example, is to slay dragons.
In order for a god to be all-knowing, he must know even the fact of his own omniscience. But can he do this? He may know the totality of facts constituting the world; call this Y. But in order to know that he has mastered Y, he must also know that 'There are no facts unknown to me' - and this is beyond Y. It seems impossible that a god (or anyone) could ever be sure that nothing exists beyond his ken. It makes no sense to imagine [a god] arriving at this limit, peering beyond it (at what?), and satisfying himself no further facts exist. But without this certainty he cannot be sure of his own omniscience, and so does not know everything. A theist might argue that his god has created all the facts in existence. But an omniscient god would have to be sure of even this - that he is the sole creator, and that there are no facts unknown to him. And how could he come to this knowledge?
As to 'facts' as a basis of understanding things in this investigative age: if there is anything greatly preferred to valid, reliable information in our culture, it is the appearance of facts - nice, tidy story lines that seem complete and perfunctory, stories that can be widely circulated in mutual agreement, despite lacking validity. And, as there are absolutely no historical facts concerning the life of Jesus of Nazareth - not a single word about him recorded during his lifetime - Christianity provides such a wonderful substitute appearance.
It is safe to assume that any individual or group you wish to influence has access to more wisdom than they currently use. It is also safe to assume that they also have considerably more facts than they can process effectively. Giving them even more facts adds to the wrong pile. They don't need more facts. They need help finding their wisdom. Contrary to popular belief, bad decisions are rarely made because people don't have all the facts.
