““Now it makes sense, for example, if the children are taking a vocabulary test of 100 words, and one of the kids misses thirteen of them, to give him an 87 percent. But we go far beyond this. A student writes an essay on a sunset, let us say, and the teacher writes 87 percent at the top of that paper. What he is saying, in effect, is that there is a mathematical metaphor operative here. The figure of 87 is to 100 what this submitted essay is . . . to what? What on earth is this supposed to mean?””
