A slave mentality which had been built into him by years of carrot-and-whip grading, a mule mentality which said, “If you don’t whip me, I won’t work… - Robert M. Pirsig

"The law of gravity and gravity itself did not exist before Isaac Newton." ...and what that means is that that law of gravity exists nowhere except in people's heads! It 's a ghost!"
Mind has no matter or energy but they can't escape its predominance over everything they do. Logic exists in the mind. numbers exist only in the mind. I don't get upset when scientists say that ghosts exist in the mind. it's that only that gets me. science is only in your mind too, it's just that that doesn't make it bad. or ghosts either."
Laws of nature are human inventions, like ghosts. Law of logic, of mathematics are also human inventions, like ghosts."
...we see what we see because these ghosts show it to us, ghosts of Moses and Christ and the Buddha, and Plato, and Descartes, and Rousseau and Jefferson and Lincoln, on and on and on. Isaac Newton is a very good ghost. One of the best. Your common sense is nothing more than the voices of thousands and thousands of these ghosts from the past."

Insanity as an absence of common characteristics is also demonstrated by the Rorschach ink-blot test for schizophrenia. In this test, randomly formed ink splotches are shown to the patient and he is asked what he sees. If he says, 'I see a pretty lady with a flowering hat,' that is not a sign of schizophrenia. But if he says, 'All I see is an ink-blot,' he is showing signs of schizophrenia. The person who responds with the most elaborate lie gets the highest score for sanity. The person who tells the absolute truth does not. Sanity is not truth. Sanity is conformity to what is socially expected. Truth is sometimes in conformity, sometimes not.

Mountains should be climbed with as little effort as possible and without desire. The reality of your own nature should determine the speed. If you become restless, speed up. If you become winded, slow down. You climb the mountain in an equilibrium between restlessness and exhaustion. Then, when you are no longer thinking ahead, each footstep isn't just a means to an an end but a unique event in itself. This leaf has jagged edges. This rock looks loose. From this place the snow is less visible, even though closer. These are things you should notice anyway. To live only for some future goal is shallow. It’s the sides of the mountain that sustain life, not the top. Here's where things grow.
