Robert Pirsig - Zen and the Art of Motorcycle Maintenance

The first tappet is right on, no adjustment required, so I move on to the next. Still plenty of time before the sun gets past those trees — I always feel like I’m in church when I do this. The gage is some kind of religious icon and I’m performing a holy rite with it. It is a member of a set called “precision measuring instruments” which in a classic sense has a profound meaning.

In a motorcycle this precision isn’t maintained for any romantic or perfectionist reasons. It’s simply that the enormous forces of heat and explosive pressure inside this engine can only be controlled through the kind of precision these instruments give. When each explosion takes place it drives a connecting rod onto the crankshaft with a surface pressure of many tons per square inch. If the fit of the rod to the crankshaft is precise the explosion force will be transferred smoothly and the metal will be able to stand it. But if the fit is loose by a distance of only a few thousandths of an inch the force will be delivered suddenly, like a hammer blow, and the rod, bearing and crankshaft surface will soon be pounded flat, creating a noise which at first sounds a lot like loose tappets. That’s the reason I’m checking it now. If it is a loose rod and I try to make it to the mountains without an overhaul, it will soon get louder and louder until the rod tears itself free, slams into the spinning crankshaft and destroys the engine. Sometimes broken rods will pile right down through the crankcase and dump all the oil onto the road. All you can do then is start walking.

But all this can be prevented by a few thousandths of an inch fit which precision measuring instruments give, and this is their classical beauty… not what you see, but what they mean… what they are capable of in terms of control of underlying form.

The second tappet’s fine. I swing over to the street side of the machine and start on the other cylinder.

Precision instruments are designed to achieve an idea, dimensional precision, whose perfection is impossible. There is no perfectly shaped part of the motorcycle and never will be, but when you come as close as these instruments take you, remarkable things happen, and you go flying across the countryside under a power that would be called magic if it were not so completely rational in every way. It’s the understanding of this rational intellectual idea that’s fundamental. John looks at the motorcycle and he sees steel in various shapes and has negative feelings about these steel shapes and turns off the whole thing. I look at the shapes of the steel now and I see ideas. He thinks I’m working on parts. I’m working on concepts.

I was talking about these concepts yesterday when I said that a motorcycle can be divided according to its components and according to its functions. When I said that suddenly I created a set of boxes with the following arrangement:

motorcycle

components

functions

And when I said the components may be subdivided into a power assembly and a running assembly, suddenly appear some more little boxes:

motorcycle

components

functions

power assembly

running assembly

And you see that every time I made a further division, up came more boxes based on these divisions until I had a huge pyramid of boxes. Finally you see that while I was splitting the cycle up into finer and finer pieces, I was also building a structure.

This structure of concepts is formally called a hierarchy and since ancient times has been a basic structure for all Western knowledge. Kingdoms, empires, churches, armies have all been structured into hierarchies. Modern businesses are so structured. Tables of contents of reference material are so structured, mechanical assemblies, computer software, all scientific and technical knowledge is so structured… so much so that in some fields such as biology, the hierarchy of kingdom-phylum-class-order-family-genus-species is almost an icon.

The box “motorcycle” contains the boxes “components” and “functions.” The box “components” contains the boxes “power assembly” and “running assembly”, and so on. There are many other kinds of structures produced by other operators such as “causes” which produce long chain structures of the form, “A causes B which causes C which causes D”, and so on. A functional description of the motorcycle uses this structure. The operator’s “exists”, “equals”, and “implies” produce still other structures. These structures are normally interrelated in patterns and paths so complex and so enormous no one person can understand more than a small part of them in his lifetime. The overall name of these interrelated structures, the genus of which the hierarchy of containment and structure of causation are just species, is system. The motorcycle is a system. A real system.

To speak of certain government and establishment institutions as “the system” is to speak correctly, since these organizations are founded upon the same structural conceptual relationships as a motorcycle. They are sustained by structural relationships even when they have lost all other meaning and purpose. People arrive at a factory and perform a totally meaningless task from eight to five without question because the structure demands that it be that way. There’s no villain, no “mean guy” who wants them to live meaningless lives, it’s just that the structure, the system demands it and no one is willing to take on the formidable task of changing the structure just because it is meaningless.

But to tear down a factory or to revolt against a government or to avoid repair of a motorcycle because it is a system is to attack effects rather than causes; and as long as the attack is upon effects only, no change is possible. The true system, the real system, is our present construction of systematic thought itself, rationality itself, and if a factory is torn down but the rationality which produced it is left standing, then that rationality will simply produce another factory. If a revolution destroys a systematic government, but the systematic patterns of thought that produced that government are left intact, then those patterns will repeat themselves in the succeeding government. There’s so much talk about the system. And so little understanding.

That’s all the motorcycle is, a system of concepts worked out in steel. There’s no part in it, no shape in it, that is not out of someone’s mind — number three tappet is right on too. One more to go. This had better be it. I’ve noticed that people who have never worked with steel have trouble seeing this… that the motorcycle is primarily a mental phenomenon. They associate metal with given shapes… pipes, rods, girders, tools, parts… all of them fixed and inviolable, and think of it as primarily physical. But a person who does machining or foundry work or forge work or welding sees “steel” as having no shape at all. Steel can be any shape you want if you are skilled enough, and any shape but the one you want if you are not. Shapes, like this tappet, are what you arrive at, what you give to the steel. Steel has no more shape than this old pile of dirt on the engine here. These shapes are all out of someone’s mind. That’s important to see. The steel? Hell, even the steel is out of someone’s mind. There’s no steel in nature. Anyone from the Bronze Age could have told you that. All nature has is a potential for steel. There’s nothing else there. But what’s “potential”? That’s also in someone’s mind! — Ghosts.

That’s really what Phædrus was talking about when he said it’s all in the mind. It sounds insane when you just jump up and say it without reference to anything specific like an engine. But when you tie it down to something specific and concrete, the insane sound tends to disappear and you see he could have been saying something of importance.
