I've got a phobia about crossed or jimmied or rust-jammed or dirt-jammed threads that cause nuts to turn slow or hard; and when I find one, I take its dimensions with a thread gauge and calipers, get out the taps and dies, recut the threads on it, then examine it and oil it and I have a whole new perspective on patience. Another one is cleaning up tools that have been used and not put away and are cluttering up the place. This is a good one because one of the first warning signs of impatience is frustration at not being able to lay your hand on the tool you need right away. If you just stop and put tools away neatly you will both find the tool and also scale down your impatience without wasting time or endangering the work.

Well, that about does it for value traps. There's a whole lot more of them, of course. I've really only just touched on the subject to show what's there. Almost any mechanic could fill you in for hours on value traps he's discovered that I don't know anything about. You're bound to discover plenty of them for yourself on almost every job. Perhaps the best single thing to learn is to recognize a value trap when you're in it and work on that before you continue on the machine.

Truth traps are concerned with data that are apprehended and are within the boxcars of the train. For the most part these data are properly handled by conventional dualistic logic and the scientific method talked about earlier, back just after Miles City. But there's one trap that isn't…the truth trap of yes-no logic. Yes and no -- this or that -- one or zero. On the basis of this elementary two-term discrimination, all human knowledge is built up. The demonstration of this is the computer memory which stores all its knowledge in the form of binary information. It contains ones and zeros, that's all. Because we're unaccustomed to it, we don't usually see that there's a third possible logical term equal to yes and no which is capable of expanding our understanding in an unrecognized direction. We don't even have a term for it, so I'll have to use the Japanese mu. Mu means "no thing." Like "Quality" it points outside the process of dualistic discrimination. Mu simply says, "No class; not one, not zero, not yes, not no." It states that the context of the question is such that a yes or no answer is in error and should not be given. "Unask the question" is what it says. Mu becomes appropriate when the context of the question becomes too small for the truth of the answer. When the Zen monk Joshu was asked whether a dog had a Buddha nature he said "Mu," meaning that if he answered either way he was answering incorrectly. The Buddha nature cannot be captured by yes or no questions. That mu exists in the natural world investigated by science is evident. It's just that, as usual, we're trained not to see it by our heritage. For example, it's stated over and over again that computer circuits exhibit only two states, a voltage for "one" and a voltage for "zero." That's silly. Any computer-electronics technician knows otherwise. Try to find a voltage representing one or zero when the power is off! The circuits are in a mu state. They aren't at one, they aren't at zero, they're in an indeterminate state that has no meaning in terms of ones or zeros. Readings of the voltmeter will show, in many cases, "floating ground" characteristics, in which the technician isn't reading characteristics of the computer circuits at all but characteristics of the voltmeter itself. What's happened is that the power-off condition is part of a context larger than the context in which the one zero states are considered universal. The question of one or zero has been "unasked." And there are plenty of other computer conditions besides a power-off condition in which mu answers are found because of larger contexts than the one-zero universality. The dualistic mind tends to think of mu occurrences in nature as a kind of contextual cheating, or irrelevance, but mu is found throughout all scientific investigation, and nature doesn't cheat, and nature's answers are never irrelevant. It's a great mistake, a kind of dishonesty, to sweep nature's mu answers under the carpet. Recognition and valuatian of these answers would do a lot to bring logical theory closer to experimental practice. Every laboratory scientist knows that very often his experimental results provide mu answers to the yes-no questions the experiments were designed for. In these cases he considers the experiment poorly designed, chides himself for stupidity and at best considers the "wasted" experiment which has provided the mu answer to be a kind of wheel-spinning which might help prevent mistakes in the design of future yes-no experiments. This low evaluation of the experiment which provided the mu answer isn't justified. The mu answer is an important one. It's told the scientist that the context of his question is too small for nature's answer and that he must enlarge the context of the question. That is a very important answer! His understanding of nature is tremendously improved by it, which was the purpose of the experiment in the first place. A very strong case can be made for the statement that science grows by its mu answers more than by its yes or no answer. Yes or no confirms or denies a hypothesis. Mu says the answer is beyond the hypothesis. Mu is the "phenomenon" that inspires scientific enquiry in the first place! There's nothing mysterious or esoteric about it. It's just that our culture has warped us to make a low value judgment of it. In motorcycle maintenance the mu answer given by the machine to many of the diagnostic questions put to it is a major cause of gumption loss. It shouldn't be! When your answer to a test is indeterminate it means one of two things: that your test procedures aren't doing what you think they are or that your understanding of the context of the question needs to be enlarged. Check your tests and restudy the question. Don't throw away those mu answers! They're every bit as vital as the yes or no answers. They're more vital. They're the ones you grow on!

The mu expansion is the only thing I want to say about truth traps at this time. Time to switch to the psychomotor traps. This is the domain of understanding which is most directly related to what happens to the machine. Here by far the most frustrating gumption trap is inadequate tools. Nothing's quite so demoralizing as a tool hang-up. Buy good tools as you can afford them and you'll never regret it. If you want to save money don't overlook the newspaper want ads. Good tools, as a rule, don't wear out, and good secondhand tools are much better than inferior new ones. Study the tool catalogs. You can learn a lot from them. Apart from bad tools, bad surroundings are a major gumption trap. Pay attention to adequate lighting. It's amazing the number of mistakes a little light can prevent. Some physical discomfort is unpreventable, but a lot of it, such as that which occurs in surroundings that are too hot or too cold, can throw your evaluations way off if you aren't careful. If you're too cold, for example, you'll hurry and probably make mistakes. If you're too hot your anger threshold gets much lower. Avoid out-of-position work when possible. A small stool on either side of the cycle will increase your patience greatly and you'll be much less likely to damage the assemblies you're working on. There's one psychomotor gumption trap, muscular insensitivity, which accounts for some real damage. It results in part from lack of kinesthesia, a failure to realize that although the externals of a cycle are rugged, inside the engine are delicate precision parts which can be easily damaged by muscular insensitivity. There's what's called "mechanic's feel," which is very obvious to those who know what it is, but hard to describe to those who don't; and when you see someone working on a machine who doesn't have it, you tend to suffer with the machine. The mechanic's feel comes from a deep inner kinesthetic feeling for the elasticity of materials. Some materials, like ceramics, have very little, so that when you thread a porcelain fitting you're very careful not to apply great pressures. Other materials, like steel, have tremendous elasticity, more than rubber, but in a range in which, unless you're working with large mechanical forces, the elasticity isn't apparent. With nuts and bolts you're in the range of large mechanical forces and you should understand that within these ranges metals are elastic. When you take up a nut there's a point called "finger-tight" where there's contact but no takeup of elasticity. Then there's "snug," in which the easy surface elasticity is taken up. Then there's a range called "tight," in which all the elasticity is taken up. The force required to reach these three points is different for each size of nut and bolt, and different for lubricated bolts and for locknuts. The forces are different for steel and cast iron and brass and aluminum and plastics and ceramics. But a person with mechanic's feel knows when something's tight and stops. A person without it goes right on past and strips the threads or breaks the assembly. A "mechanic's feel" implies not only an understanding for the elasticity of metal but for its softness. The insides of a motorcycle contain surfaces that are precise in some cases to as little as one ten-thousandth of an inch. If you drop them or get dirt on them or scratch them or bang them with a hammer they'll lose that precision. It's important to understand that the metal behind the surfaces can normally take great shock and stress but that the surfaces themselves cannot. When handling precision parts that are stuck or difficult to manipulate, a person with mechanic's feel will avoid damaging the surfaces and work with his tools on the nonprecision surfaces of the same part whenever possible.
