Of course, some people are naturally conservative; they avoid taking a position whenever possible. They just don't want to go out on a limb when they don't know the genus of the tree. For these people, the vague generality must be partially junked and replaced by the artful equivocation, or the art of talking around the point.

The artful equivocation is an almost impossible concept to explain, but it is easy to demonstrate. Let us begin with the question, "Did the philosophical beliefs of Hume represent the spirit of the age in which he lived?"

The equivocator would answer it in this way: "Some people believe that David Hume was not necessarily a great philosopher because his thought was merely a reflection of conditions around him, colored by his own personality.

"Others, however, strongly support Hume's greatness on the ground that the force of his personality definitely affected the age in which he lived. It is not a question of the cart before the horse in either case, merely the old problem of which came first, the chicken or the egg. In any case, there is much to be said on both sides."

Just exactly what our equivocator's answer has to do with the original question is hard to say. The equivocator writes an essay about the point, but never on it.

Consequently, the grader often mentally assumes that the right answer is known by the equivocator and marks the essay as an extension of the point rather than a complete irrelevance.

The artful equivocation must imply the writer knows the right answer, but it must never get definite enough to eliminate any possibilities.

There is a third method of dealing with examination questions--that is by the use of the over-powering assumption, an assumption so cosmic that it is sometimes accepted. For example, we wrote that it was pretty obvious that the vague generality was the key device in any discussion, of examination writing. Why is it obvious? As a matter of fact it wasn't obvious at all, but just an arbitrary point from which to start. That is an example of an unwarranted assumption.

In the long run the expert in the use of unwarranted assumption comes off better than the equivocator. He would deal with our question on Hume not by baffling the grader or by fencing with him but like this: "It is absurd to discuss whether Hume is representative of the age in which he lived unless we note the progress of that age on all fronts. After all, Hume did not live in a vacuum."'

At this point our assumption expert proceeds to discuss anything which strikes his fancy at the moment. If he can sneak the first assumption past the grader, then the rest is clear sailing. If he fails, he still gets a fair amount of credit for his irrelevant but fact-filled discussion of scientific progress in the 18th century. And it is amazing what some graders will swallow in the name of intellectual freedom.
