Sam Harris

Everything we do is for the purpose of altering consciousness. We form friendships so that we can feel certain emotions, like love, and avoid others, like loneliness. We eat specific foods to enjoy their fleeting presence on our tongues. We read for the pleasure of thinking another person's thoughts.

What I'm asking you to entertain is that there is nothing we need to believe on insufficient evidence in order to have deeply ethical and spiritual lives.

The core of science is not a mathematical modeling--it is intellectual honesty. It is a willingness to have our certainties about the world constrained by good evidence and good argument.

It is time that we admitted that faith is nothing more than the license religious people give one another to keep believing when reasons fail.

It is taboo in our society to criticize a persons religious faith... these taboos are offensive, deeply unreasonable, but worse than that, they are getting people killed. This is really my concern. My concern is that our religions, the diversity of our religious doctrines, is going to get us killed. I'm worried that our religious discourse- our religious beliefs are ultimately incompatible with civilization.

It is time that scientists and other public intellectuals observed that the contest between faith and reason is zero-sum.

It is also true that the less competent a person is in a given domain, the more he will tend to overestimate his abilities. This often produces an ugly marriage of confidence and ignorance that is very difficult to correct for.

My concern with religion is that it allows us by the millions to believe what only lunatics or idiots could believe on their own. That's not to say that all religious people are lunatics or idiots. It's anything but that.

Spiritual life can certainly follow the pattern one sees in the fake martial arts, with most teachers making nebulous and magical claims that never get tested, while their students derange themselves with weird ideas, empty rituals, and other affectations.

It is still fashionable to believe that how you organize yourself religiously in this life may matter for eternity. Unless we can erode the prestige of that kind of thinking, we're not going to be able to undermine these divisions in our world.

Imagine a world in which generations of human beings come to believe that certain films were made by God or that specific software was coded by him. Imagine a future in which millions of our descendants murder each other over rival interpretations of Star Wars or Windows 98. Could anything -- anything -- be more ridiculous? And yet, this would be no more ridiculous than the world we are living in.

How can we be “free” as conscious agents if everything that we consciously intend is caused by events in our brain that we do not intend and of which we are entirely unaware? We can’t.

When considering the truth of a proposition, one is either engaged in an honest appraisal of the evidence and logical arguments, or one isn't. Religion is one area of our lives where people imagine that some other standard of intellectual integrity applies.

Every one of the world's "great" religions utterly trivializes the immensity and beauty of the cosmos. Books like the Bible and the Koran get almost every significant fact about us and our world wrong. Every scientific domain -- from cosmology to psychology to economics -- has superseded and surpassed the wisdom of Scripture. Everything of value that people get from religion can be had more honestly, without presuming anything on insufficient evidence. The rest is self-deception, set to music.

The only thing that guarantees an open-ended collaboration among human beings, the only thing that guarantees that this project is truly open-ended, is a willingness to have our beliefs and behaviors modified by the power of conversation.

The usefulness of religion - the fact that it gives life meaning, that it makes people feel good - is not an argument for the truth of any religious doctrine. It's not an argument that it's reasonable to believe that Jesus really was born of a virgin or that the Bible is the perfect word of the creator of the universe.

A kernel of truth lurks at the heart of religion, because spiritual experience, ethical behavior, and strong communities are essential for human happiness. And yet our religious traditions are intellectually defunct and politically ruinous. While spiritual experience is clearly a natural propensity of the human mind, we need not believe anything on insufficient evidence to actualize it.

According to the most common interpretation of biblical prophecy, Jesus will return only after things have gone horribly awry. Imagine the consequences if any significant component of the U.S. government 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 should be considered a moral and intellectual emergency.

Science, in the broadest sense, includes all reasonable claims to knowledge about ourselves and the world.

Morality must relate, at some level, to the well-being of conscious creatures. If there are more and less effective ways for us to seek happiness and to avoid misery in this world - and there clearly are - then there are right and wrong answers to questions of morality.

We have Christians against Muslims against Jews, and no matter how liberal your theology, merely identifying yourself as a Christian or a Jew lends tacit validity to this status quo. People have morally identified with a subset of humanity rather than with humanity as a whole.
