“Perhaps randomness is not merely an adequate description for complex causes that we cannot specify. Perhaps the world really works this way, and many events are uncaused in any conventional sense of the word. Perhaps our gut feeling that it cannot be so reflects only our hopes and prejudices, our desperate striving to make sense of a complex and confusing world, and not the ways of nature.”

“We depend on nature not only for our physical survival. We also need nature to show us the way home, the way out of the prison of our own minds. We got lost in doing, thinking, remembering, anticipating–lost in a maze of complexity and a world of problems.”

“All we have to believe with is our senses, the tools we use to perceive the world: our sight, our touch, our memory. If they lie to us, then nothing can be trusted. And even if we do not believe, then still we cannot travel in any other way than the road our senses show us; and we must walk that road to the end.”

“We cannot go backward. We cannot erase time and events. But we can go forward, hand in hand, hope in our hearts and love lighting our way.”

“Of all the wondrous elements in our vast and complex universe, there is perhaps nothing more intriguing, than consciousness.”

“Lavoisier was right in the deepest, almost holy, way. His passion harnessed feeling to the service of reason; another kind of passion was the price. Reason cannot save us and can even persecute us in the wrong hands; but we have no hope of salvation without reason. The world is too complex, too intransigent; we cannot bend it to our simple will.”

“The point of meditation is not merely to be an honest or good person in the conventional sense, trying only to maintain our security. We must begin to become compassionate and wise in the fundamental sense, open and relating to the world as it is.”

“Perhaps consciousness arises when the brain's simulation of the world becomes so complex that it must include a model of itself.”

“Just as there are odors that dogs can smell and we cannot, as well as sounds that dogs can hear and we cannot, so too there are wavelengths of light we cannot see and flavors we cannot taste. Why then, given our brains wired the way they are, does the remark, "Perhaps there are thoughts we cannot think," surprise you?”

“"Old" and "new" are the perennial poles of all feeling and sense of orientation in the world. We cannot do without the old, because in what is old is invested all our past, our wisdom, our memories, our sadness, our sense of realism. We cannot do without faith in the new, because in what is new is invested all our energy, our capacity for optimism, our blind biological yearning, our ability to forget — the healing ability that makes reconciliation possible.”
