This is the prime example of how religious brainwashing works. People are told that morals come from God. But the facts say otherwise. Moral concepts such as the Golden Rule were around centuries before Jesus. They are the collective principles of humanity. Studies show that atheists are at least as moral as theists, and certainly there is a connection between fundamentalism, in Islam and Christianity, and antisocial behavior. I prefer to call myself a humanist rather than an atheist because Humanism is the source of our morality and provides a positive outlook on life.

Q. Religion in everyday life is understood as something uncontestable while scientific theories are considered debatable. How can we provide a more open attitude towards investigating religion?

Religion makes testable claims so these can be treated the same as any scientific claim. I document these in detail in the book, but let me give you one example. Most believers do a lot of praying and think it has a positive effect. These effects should be observable. Controlled experiments have been done and have found no effects. It could have turned out otherwise, in which case I would have to admit that science had found God.

Q. It is a well known fact that very few people actually ever read the religious texts and it is likely that very few of those who read them understand them. So there is chasm between the way a religion is lived and the way it was fundamentally conceived and hence the numerous 'fundamentalist' movements. The argument that I am making is that 'faith' that is driving most religious people is of a vague though absolute kind. Debunking the extraordinary stories of the books, and even providing convincing arguments against God is unlikely to change the views of the majority of religious people.

Probably. But there are still a lot of people I think I can reach with rational arguments: agnostics; believers who are not too sure; young people, especially college students who are learning to think critically and have not yet formed their views. Also I provide ammunition for those who think like I do to use in their arguments with believers.

Q. Science thrives on the parsimonious model. One shouldn't create something if it isn't needed to explain the phenomenon at hand. Hence if all 'natural' phenomena can be conceivably explained by variables at hand then why devise new ones. This, I believe, is one of the chief arguments that you try to make about absence of God. Can you expand a little more on this?

In an earlier book, Has Science Found God? I refute the claims that there is scientific evidence for God. In this book I go much further than just the absence of evidence argument that you reiterate in your question. I claim there is positive scientific evidence against the existence of the God most people worship, as in the absence of support for the efficacy of prayer that I mentioned earlier.
