It is often very illuminating...to ask yourself how you got at the facts on which you base your opinion. Who actually saw, heard, felt, counted, named the thing, about which you have an opinion?
We are told about the world before we see it. We imagine most things before we experience them. And those preconceptions, unless education has made us acutely aware, govern deeply the whole process of perception.
For the real environment is altogether too big, too complex, and too fleeting for direct acquaintance. We are not equipped to deal with so much subtlety, so much variety, so many permutations and combinations. And although we have to act in that environment, we have to reconstruct it on a simpler model before we can manage it.
As you go further away from experience, you go higher into generalization or subtlety. As you go up in the balloon you throw more and more concrete objects overboard, and when you have reached the top with some phrase like the Rights of Humanity or the World Made Safe for Democracy, you see far and wide, but you see very little.
We are unsettled to the very roots of our being. There isn't a human relation, whether of parent and child, husband and wife, worker and employer, that doesn't move in a strange direction. We don't know how to behave when personal contact and eternal authority have disappeared. There are no precedents to guide us, no wisdom that wasn't made for a simpler age. We have changed our environment faster than we can change ourselves.
The war, of course, furnished many examples of this pattern: the casual fact, the creative imagination, the will to believe, and out of these three elements, a counterfeit of reality to which there was a violent instinctive response. For it is clear enough that under certain conditions men respond as powerfully to fictions as they do to realities, and that in many cases they help to create the very fictions to which they respond.
Photographs have the kind of authority over imagination to-day, which the printed word had yesterday, and the spoken word before that. They seem utterly real. They come, we imagine, directly to us without human meddling, and they are the most effortless food for the mind conceivable. Any description in words, or even any inert picture exists in the mind. But on the screen the whole process of observing, describing, reporting, and then imagining, has been accomplished for you.
The opposition is indispensable. A good statesman, like any other sensible human being, always learns more from his opponents than from his fervent supporters. For his supporters will push him to disaster unless his opponents show him where the dangers are. So if he is wise he will often pray to be delivered from his friends, because they will ruin him. But, though it hurts, he ought also to pray never to be left without opponents; for they keep him on the path of reason and good sense.
The systems of stereotypes may be the core of our personal tradition, the defenses of our position in society. They are an ordered more or less consistent picture of the world, to which our habits, our tastes, our capacities, our comforts and our hopes have adjusted themselves. They may not be a complete picture of the world, but they are a picture of a possible world to which we are adapted. In that world, people and things have their well-known places, and do certain expected things. We feel at home there. We fit in. We are members.
