"The study of the art of motorcycle maintenance is really a miniature study of the art of rationality itself. Working on a motorcycle, working well, caring, is to become part of a process, to achieve an inner peace of mind. The motorcycle is primarily a mental phenomenon."

"Many people have said to me that I'm a mystic. I find that a bit mysterious. I just use logic and common sense for my philosophies."

"Logic, n. The art of thinking and reasoning in strict accordance with the limitations and incapacities of the human misunderstanding. The basic of logic is the syllogism, consisting of a major and a minor premise and a conclusion - thus:Major Premise: Sixty men can do a piece of work sixty times as quickly as one man.Minor Premise: One man can dig a post-hole in sixty seconds; Therefore-Conclusion: Sixty men can dig a post-hole in one second.This may be called syllogism arithmetical, in which, by combining logic and mathematics, we obtain a double certainty and are twice blessed."

"There is no logic in logics except an illogical logic."

"Rationality and common sense never goes out of fashion."

"Don't you believe in flying saucers, they ask me? Don't you believe in telepathy? - in ancient astronauts? - in the Bermuda triangle? - in life after death?No, I reply. No, no, no, no, and again no.One person recently, goaded into desperation by the litany of unrelieved negation, burst out "Don't you believe in anything?"Yes", I said. "I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be."

"Apriority creates ambiguities among ideas."

"But twice-two-makes-four is for all that a most insupportable thing. Twice-two-makes-four is, in my humble opinion, nothing but a piece of impudence. Twice-two-makes-four is a farcical, dressed-up fellow who stands across your path with arms akimbo and spits at you."

"Like those in the valley behind us, most people stand in sight of the spiritual mountains all their lives and never enter them, being content to listen to others who have been there and thus avoid the hardships."

"To some extent the romantic condemnation of rationality stems from the very effectiveness of rationality in uplifting men from primitive conditions."

"If I hold my head to the left and look down at the handle grips and front wheel and map carrier and gas tank I get one pattern of sense data. If I move my head to the right I get another slightly different pattern of sense data. The two views are different. The angles of the planes and curves of the metal are different. The sunlight strikes them differently. If there's no logical basis for substance then there's no logical basis for concluding that what's produced these two views is the same motorcycle."

"He'd no longer be a grade-motivated person. He'd be a knowledge-motivated person. He would need no external pushing to learn. His push would come from inside. He'd be a free man. He wouldn't need a lot of discipline to shape him up. In fact, if the instructors assigned him were slacking on the job he would be likely to shape them up by asking rude questions. He'd be there to learn something, would be paying to learn something and they'd better come up with it.Motivation of this sort, once it catches hold, is a ferocious force..."

"Not everyone understands what a completely rational process this is, this maintenance of a motorcycle. They think it's some kind of 'knack' or some kind of 'affinity for machines' in operation. They are right, but the knack is almost purely a process of reason, and most of the troubles are caused by what old time radio men called a 'short between the earphones,' failures to use the head properly. A motorcycle functions entirely in accordance with the laws of reason, and a study of the art of motorcycle maintenance is really a miniature study of the art of rationality itself."

"Or winters when the sloughs were frozen over and dead and i could walk across the ice and snow between the dead cattails and see nothing but grey skies and dead things and cold."

"He felt that institutions such as schools, churches, governments and political organizations of every sort all tended to direct thought for ends other than truth, for the perpetuation of their own functions, and for the control of individuals in the service of these functions. He came to see his early failure as a lucky break, an accidental escape from a trap that had been set for him, and he was very trap-wary about institutional truths for the remainder of his time."

"The primitive tribes permitted far less individual freedom than does modern society. Ancient wars were committed with far less moral justification than modern ones. A technology that produces debris can find, and is finding, ways of disposing of it without ecological upset. And the schoolbook pictures of primitive man sometimes omit some of the detractions of his primitive life - the pain, the disease, famine, the hard labor needed just to stay alive. From that agony of bare existence to modern life can be soberly described only as upward progress, and the sole agent for this progress is quite clearly reason itself."

"We want to make good time, but for us now this is measured with the emphasis on 'good' rather than on 'time'...."
