“I can easily believe that there are more invisible creatures in the universe than visible ones. But who will tell us to what family each belongs, their ranks and relationships, and what their distinguishing characteristics may be? What do they do? The human mind has always circled around these matters without finding satisfaction. But I do not doubt that it is beneficial sometimes to contemplate in the mind, as in a picture, the image of a grander and better world; for if the mind becomes used to the trivial things of everyday life, it may limit itself too much and decline completely into worthless thinking. Meanwhile, however, we must be on the lookout for the truth, keeping a sense of proportion so that we can distinguish what is sure from what is uncertain, and day from night.”

“How different our lives are when we really know what is deeply important to us, and keeping that picture in mind, we manage ourselves each day to be and to do what really matters most.”

“I no longer believe that we can keep silent. We never really do, mind you. In one way or another we articulate what has happened to us through the kind of people we become.”

“We are part of the universe that has developed a remarkable ability: We can hold an image of the world in our minds. We are matter contemplating itself.”

“The mind commands the body, and obedience is instant; the mind commands itself and meets resistance. The mind tells the hand to move, and all goes so smoothly that it is hard to distinguish the command from its execution. Yet the mind is the mind, and the hand is a body. The mind tells the mind to will; one is the same as the other, and yet it does not do what it is told.”

“What we can do, we must do: we must use what we are given, and we must use it the best we can, however much or little help we have for the task. What you have been given is a hard thing--a very hard thing... But my darling, what if there were no one who could do the difficult things?”
