Some more excerpt from book....
The idea that the majority of students attend a university for an education independent of the degree and grades is a little hypocrisy everyone is happier not to expose. Occasionally some students do arrive for an education but rote and the mechanical nature of the institution soon converts them to a less idealistic attitude.
The demonstrator was an argument that elimination of grades and degrees would destroy this hypocrisy. Rather than deal with generalities it dealt with the specific career of an imaginary student who more or less typified what was found in the classroom, a student completely conditioned to work for a grade rather than for the knowledge the grade was supposed to represent.
Such a student, the demonstrator hypothesized, would go to his first class, get his first assignment and probably do it out of habit. He might go to his second and third as well. But eventually the novelty of the course would wear off and, because his academic life was not his only life, the pressure of other obligations or events would create circumstances where he just would not be able to get an assignment completed adequately.
Since there was no degree or grading system he would incur no penalty for this. Subsequent lectures which presumed he'd completed the assignment might be a little more difficult to understand, however, and this difficulty, in turn, might weaken his interest to a point where the next assignment, which he would find quite hard, would also be dropped. Again no penalty.
In time his weaker and weaker understanding of what the lectures were about would make it more and more difficult for him to pay attention in class. Eventually he would see he wasn't learning much; and facing the continual pressure of outside obligations, he would stop studying, feel guilty about this and stop attending class. Again, no penalty would be attached.
But what had happened? The student, with no hard feelings on anybody's part, would have flunked himself out. Good! This is what should have happened. A large amount of money and effort had been saved and there would be no stigma of failure and ruin to haunt him the rest of his life. No bridges had been burned.
