“One of the reasons for its success is that science has a built-in, error-correcting machinery at its very heart. Some may consider this an overbroad characterization, but to me every time we exercise self-criticism, every time we test our ideas against the outside world, we are doing science. When we are self-indulgent and uncritical, when we confuse hopes and facts, we slide into pseudoscience and superstition.”

“The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities — perhaps the only one — in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there.”

“When outsiders criticize Americans, they regularly note that we seem self-centered, which we are. But few contend we are selfish, and with good reason; we are not.”

“In its quest to discover how the patterns of reality are organised, the story of modern science hints at a picture of a set of Chinese puzzle boxes, each one more intricately structured and wondrous than the last. Every time the final box appears to have been reached, a key has been found which has opened up another, revealing a new universe even more breathtakingly improbable in its conception. We are now forced to suspect that, for human reason, there is no last box, that in some deeply mysterious, virtually unfathomable, self-reflective way, every time we open a still smaller box, we are actually being brought closer to the box with which we started, the box which contains our own conscious experience of the world. This is why no theory of knowledge, no epistemology, can ever escape being consumed by its own self-generated paradoxes. And this is why we must consider the universe to be irredeemably mystical.”

“I think that perhaps we always fall in love the very first instant we see the man of our dreams, even though, at the time, reason may be telling us otherwise, and we may fight against that instinct, hoping against hope that we won't win, until there comes a point when we allow ourselves to be vanquished by our feelings.”
