“We all make basic assumptions about things in life, but sometimes those assumptions are WRONG. We must never trust in what we assume, only in what we KNOW.”

“If others tell us something we make assumptions, and if they don't tell us something we make assumptions to fulfill our need to know and to replace the need to communicate. Even if we hear something and we don't understand we make assumptions about what it means and then believe the assumptions. We make all sorts of assumptions because we don't have the courage to ask questions.”

“We have lived our lives by the assumption that what was good for us would be good for the world. We have been wrong. We must change our lives so that it will be possible to live by the contrary assumption, that what is good for the world will be good for us. And that requires that we make the effort to know the world and learn what is good for it.”

“The games we play are lessons we learn. The assumptions we make, things we ignore, and things we change make us what we become.”

“Young man, the games we play are lessons we learn. The assumptions we make, things we ignore, and things we change make us what we become.”

“We have lived by the assumption that what was good for us would be good for the world. And this has been based on the even flimsier assumption that we could know with any certainty what was good even for us. We have fulfilled the danger of this by making our personal pride and greed the standard of our behavior toward the world - to the incalculable disadvantage of the world and every living thing in it. And now, perhaps very close to too late, our great error has become clear. It is not only our own creativity - our own capacity for life - that is stifled by our arrogant assumption; the creation itself is stifled.We have been wrong. We must change our lives, so that it will be possible to live by the contrary assumption that what is good for the world will be good for us. And that requires that we make the effort to know the world and to learn what is good for it. We must learn to cooperate in its processes, and to yield to its limits. But even more important, we must learn to acknowledge that the creation is full of mystery; we will never entirely understand it. We must abandon arrogance and stand in awe. We must recover the sense of the majesty of creation, and the ability to be worshipful in its presence. For I do not doubt that it is only on the condition of humility and reverence before the world that our species will be able to remain in it. (pg. 20, "A Native Hill")”
