Now there's nothing wrong with facts as such. Educators of necessity seek a common ground on which to reach their students.
But one of the characteristics of a fact is that it has a record of past performance. That's what makes it a fact: Phenomenon X behaved and/or existed in thus-and-such a manner yesterday, last week, last month, last year. So, we have reason to anticipate that it will behave and/or exist the same way tomorrow.
This means that to deal with facts, you must devote a great deal of attention to analysis of their track records. What did they do in previous encounters, and how did they do it? They're like cases in law: Past history dominates. First, last, and always you check precedents.
If this were as far as the matter went, there wouldn't be any real headache. But the educators refused to let it go at that. Facts were easy to present. Knowledge of them was easy to test. In many areas they were of great practical use. Centering attention on them obviated the complications that went with dealing with each student as an individual.
So, educators in the lead, an entire society plunged into wholesale fact-worship.
When you glorify one thing, it's generally at the expense of something else. In this case, the ''something else'' was feeling.
Now a feeling is about as opposite to a fact as you can get. At best, you might describe it as a sort of internal driving force, like electricity in a motor. You can't see it or hear it or smell it or taste it or touch it. It reveals itself to the outside world only in overt behavior, as a reaction. Even measuring its intensity, by any objective standard, remains a problem not at all satisfactorily resolved.
As if that weren't enough, feelings differ from moment to moment and person to person. They're the ultimate variable—utterly unpredictable, oftentimes; poker with everything wild.
Faced with this unpredictability of feelings, this refusal of an element to behave in neatly ordered fashion, the educators responded with varying degrees of uncertainty, suspicion, outrage.
—Feelings all, of course, you understand; but acceptable, because they were housed in the right people.
Being human as well as frustrated, the educators took the obvious course of action: They taught generations of children to depend on facts.
—And, as a corollary, to hold all feelings suspect.
Result: a population trained to feel guilty every time it discovers that emotion prompted an action.
