“It is time we recognized that the only thing that permits human beings to collaborate with one another in a truly open-minded way is their willingness to have their beliefs modified by new facts.”

“The only thing that guarantees an open-ended collaboration among human beings, the only thing that guarantees that this project is truly open-ended, is a willingness to have our beliefs and behaviors modified by the power of conversation.”

“We could say that the human race is a great coauthorship in which we are collaborating with God and nature in the making of ourselves and one another. From this there is no escape. We may collaborate either well or poorly or we may refuse to collaborate, but even to refuse to collaborate is to exert an influence and to affect the quality of the product. This is only a way of saying that by ourselves we have no meaning and no dignity; by ourselves we are outside the human definition, outside our identity.”

“We often think that there is just one way to look at things - the way we always have. In fact, there are an infinite number of ways to look at most everything. An open mind allows for a multitude of perspectives from which to choose in any given moment. That suppleness of mind allows for true choice, and opens us to a whole new realm of possibility.”

“Keep an open mind; it's the only way new things can get in.”

“The range of the human mind, the scale and depth of the metaphors the mind is capable of manufacturing as it grapples with the universe, stand in stunning contrast to the belief that there is only one reality, which is man's, or worse, that only one culture among the many on earth possesses the truth.To allow mystery, which is to say to yourself, "There could be more, there could be things we don't understand," is not to damn knowledge. It is to take a wider view. It is to permit yourself an extraordinary freedom: someone else does not have to be wrong in order that you may be right.”
