“Belief is one of the most powerful organic forces in the multiverse. It may not be able to move mountains, exactly. But it can create someone who can.People get exactly the wrong idea about belief. They think it works back to front. They think the sequence is, first object, then belief. In fact, it works the other way.”

“If faith is what you have to go on, if faith is the link between your beliefs and the world at large, your beliefs are very likely to be wrong. Beliefs can be right or wrong. If you believe you can fly, that belief is only true if indeed you can fly. Somebody who thinks he can fly, and is wrong about it, will eventually discover there's a problem with his view of the world.”

“There’s no question about freedom of speech when everyone thinks exactly the same and no one says anything out of the accepted norms. In this kind of climate, even the mildest questions sound like heresy, and the outcome is intolerance of other people’s beliefs, ideas, actions and freedoms.”

“Challenge a person's beliefs, and you challenge his dignity, standing, and power. And when those beliefs are based on nothing but faith, they are chronically fragile. No one gets upset about the belief that rocks fall down as opposed to up, because all sane people can see it with their own eyes. Not so for the belief that babies are born with original sin or that God exists in three persons or that Ali is the second-most divinely inspired man after Muhammad. When people organize their lives around these beliefs, and then learn of other people who seem to be doing just fine without them--or worse, who credibly rebut them--they are in danger of looking like fools. Since one cannot defend a belief based on faith by persuading skeptics it is true, the faithful are apt to react to unbelief with rage, and may try to eliminate that affront to everything that makes their lives meaningful.”

“Then in a moment, in that vast space of rocks and sky and scorching sun, I understood that he had not meant religious faith, not exactly. He was not urging me to become a Muslim or to believe in one interpretation of God rather than another. He knew me for what I was, an old, cold, cautious scientist. That was what I was then. And he was simply pointing out to me the first step to take. The word he had used was faith, but what he meant was belief. The first step was simple: it was to believe in belief itself. I had just taken that step. At long last I understood.I had belief. I did not know, or for the moment care, what exactly it was I had to believe in. I only knew that belief in something was the first step away from believing in nothing, the first step away from a world which only recognised what it could count, measure, sell or buy. The people here still had that innocent power of belief: not the angry denial of other people’s belief of religious fanatics, but a quiet affirmation. That was what I sensed here, in this land and in this place, which made it so different from home. It was not the clothes, not the language, not the customs, not the sense of being in another century. It was none of these. It was the pervading presence of belief.I believed in belief. I didn’t exactly feel as if I was on the road to Damascus, and I was aware I could not think straight because of the power of the sun, but now I knew what the Yemen salmon project was all about. It had already worked its transformation on me. It would do the same for others.”

“The world we think we see is only a view, a collective description of the world that we create through our belief systems. Accepting this fact seems to be one of the most empowering things one can do.”
