“From Richard McKeon and Robert Brumsbaugh I learned to view the history of philosophy as a series, not of alternative solutions to the same problems, but of quite different sets of problems. From Rudolph Carnap and Carl Hempel I learned how pseudo-problems could be revealed as such by restarting them in the formal mode of speech. From Charles Hartshorne and Paul Weiss I learned how they could be so revealed by being translated into Whiteheadian or Hegelian terms.”

Context: From childhood we are trained to have problems. When we are sent to school, we have to learn how to write, how to read, and all the rest of it. How to write becomes a problem to the child. Please follow this carefully. Mathematics becomes a problem, history becomes a problem, as does chemistry. So the child is educated, from childhood, to live with problems — the problem of God, problem of a dozen things. So our brains are conditioned, trained, educated to live with problems. From childhood we have done this. What happens when a brain is educated in problems? It can never solve problems; it can only create more problems. When a brain that is trained to have problems, and to live with problems, solves one problem, in the very solution of that problem, it creates more problems. From childhood we are trained, educated to live with problems and, therefore, being centred in problems, we can never solve any problem completely. It is only the free brain that is not conditioned to problems that can solve problems. It is one of our constant burdens to have problems all the time. Therefore our brains are never quiet, free to observe, to look. So we are asking: Is it possible not to have a single problem but to face problems? But to understand those problems, and to totally resolve them, the brain must be free.

Context: After 25 years of buying and supervising a great variety of businesses, Charlie and I have not learned how to solve difficult business problems. What we have learned is to avoid them. To the extent we have been successful, it is because we concentrated on identifying one-foot hurdles that we could step over because we acquired any ability to clear seven-footers.

Were cows so different from cats and dogs that there were two moral standards, one that applies to cows, another that applies to cats and dogs? Were pigs so different? Were any of the animals I ate so different?
