“Losing a belief in free will has not made me fatalistic—in fact, it has increased my feelings of freedom. My hopes, fears, and neuroses seem less personal and indelible. There is no telling how much I might change in the future. Just as one wouldn’t draw a lasting conclusion about oneself on the basis of a brief experience of indigestion, one needn’t do so on the basis of how one has thought or behaved for vast stretches of time in the past. A creative change of inputs to the system—learning new skills, forming new relationships, adopting new habits of attention—may radically transform one’s life.”

“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 problem I want to talk to you about tonight is the problem of belief. What does it mean to believe? We use this word all the time, and I think behind it lurk some really extraordinary taboos and confusions. What I want to argue tonight is that how we talk about belief- how we fail to criticize or criticize the beliefs of others, has more importance to us personally, more consequence to us personally and to civilization than perhaps anything else that is in our power to influence. ”

“How is it that, in this one area of our lives [religion], we have convinced ourselves that our beliefs about the world can float entirely free of reason and evidence?”

“Is is, therefore, not an exaggeration to say that if the city of New York were suddenly replaced by a ball of fire, some significant percentage of the American population would see a silver-lining in the subsequent mushroom cloud, as it would suggest to them that the best thing that is ever going to happen was about to happen: the return of Christ. It should be blindingly obvious that beliefs of this sort will do little to help us create a durable future for ourselves - socially, economically, environmentally, or geopolitically. Imagine the consequences if any significant component of the US government actually believed that the world was about to end and that its ending would be glorious. The fact that nearly half of the American population apparently believes this, purely on the basis of religion dogma, should be considered a moral and intellectual emergency.”

“It is time we recognized that belief is not a private matter; it has never been merely private. In fact, beliefs are scarcely more private than actions are, for every belief is a fount of action in potentia.”

“This is not (as you have charged) to paint religion with a broad brush. I am very quick to distinguish gradations of bad ideas; some clearly have no consequences at all (or at least not yet); some put civilization itself in peril. The problem with dogmatism, however, is that one can never quite predict how terrible its costs will be. To use one of my favorite examples, consider the Christian dogma that human life begins at the moment of conception: On its face, this belief seems likely to only improve our world. After all, it is the very quintessence of a life-affirming doctrine.Enter embryonic stem-cell research. Suddenly, this “life begins at the moment of conception” business becomes the chief impediment to medical progress. Who would have thought that such an innocuous idea could unnecessarily prolong the agony of tens of millions of people? This is the problem with dogmatism, no matter how seemingly benign: it is unresponsive to reality. Dogmatism is a failure of cognition (as well as a commitment to such failure); it is the state of being closed to new evidence and new arguments. And this frame of mind is rightly despised in every area of culture, on every subject, except where it goes by the name of “religious faith.” In this guise, parading its most grotesque faults as virtues, it is granted a special dispensation, even in the pages of Nature.”
