“Sometimes it feels like I'm thinking against the wind.”

“The ability to retain a child's view of the world with at the same time a mature understanding of what it means to retain it, is extremely rare - and a person who has these qualities is likely to be able to contribute something really important to our thinking.”

“If you ask a living teacher a question, he will probably answer you. If you are puzzled by what he says, you can save yourself the trouble of thinking by asking him what he means. If, however, you ask a book a question, you must answer it yourself. In this respect a book is like nature or the world. When you question it, it answers you only to the extent that you do the work of thinking an analysis yourself.”

“The person who says he knows what he thinks but cannot express it usually does not know what he thinks.”

“There are genuine mysteries in the world that mark the limits of human knowing and thinking. Wisdom is fortified, not destroyed, by understanding its limitations. Ignorance does not make a fool as surely as self-deception.”

“Only hidden and undetected oratory is really insidious. What reaches the heart without going through the mind is likely to bounce back and put the mind out of business.”

“Television, radio, and all the sources of amusement and information that surround us in our daily lives are also artificial props. They can give us the impression that our minds are active, because we are required to react to stimuli from the outside. But the power of those external stimuli to keep us going is limited. They are like drugs. We grow used to them, and we continuously need more and more of them. Eventually, they have little or no effect. Then, if we lack resources within ourselves, we cease to grow intellectually, morally, and spiritually. And we we cease to grow, we begin to die.”
