“There are at least two ways to believe in the idea of quality. You can believe there's something ineffable going on within the human mind, or you can believe we just don't understand what quality in a mind is yet, even though we might someday. Either of those opinions allows one to distinguish quantity and quality. In order to confuse quantity and quality, you have to reject both possibilities. The mere possibility of there being something ineffable about personhood is what drives many technologists to reject the notion of quality. They want to live in an airtight reality that resembles an idealized computer program, in which everything is understood and there are no fundamental mysteries. They recoil from even the hint of a potential zone of mystery or an unresolved seam in one's worldview. This desire for absolute order usually leads to tears in human affairs, so there is a historical reason to distrust it. Materialist extremists have long seemed determined to win a race with religious fanatics: Who can do the most damage to the most people?”

“We should believe in quality of books rather than quantity of books.”

“the quality of your thinking is largely determined by the quantity of the information you have with which to work ”

“The most important and most significant good quality in our human life is gratitude. Unfortunately, that good quality we somehow manage not to express either in our thoughts or in our actions. Right from the beginning of our life, we have somehow learned not to express it. So we have the least amount of the very thing that we need most in order to become a better person.”

“Everything we know, believe, want, fear, and hope for, our thinking tells us. It follows, then, that the quality of our thinking is the primary determinant of the quality of our lives.”
