Mohammed was not an apparent failure. He was a dazzling success, politically as well as spiritually, and Islam went from strength to strength to strength.

I am not interested in the afterlife. Religion is supposed to be about losing your ego, not preserving it eternally in optimum conditions.

Compassion is not a popular virtue. Very often when I talk to religious people, and mention how important it is that compassion is the key, that it's the sine-qua-non of religion, people look kind of balked, and stubborn sometimes, as much to say, what's the point of having religion if you can't disapprove of other people?

Religious people often prefer to be right rather than compassionate. Often, they don't want to give up their egotism. They want their religion to endorse their ego, their identity.

Zionism was originally a rebellion against religious Judaism and the PLO Charter was essentially secularist. But because the conflict was allowed to fester without a resolution, religion got sucked into the escalating cycle of violence and became part of the problem.

There are some forms of religion that are bad, just as there's bad cooking or bad art or bad sex, you have bad religion too.

Well, logos is science or reason, something that helps us to function practically and effectively in the world, and it must therefore be closely in tune and reflect accurately the realities of the world around us.

We have domesticated God's transcendence. We often learn about God at about the same time as we are learning about Santa Claus; but our ideas about Santa Claus change, mature and become more nuanced, whereas our ideas of God can remain at a rather infantile level.

Today mythical thinking has fallen into disrepute; we often dismiss it as irrational and self-indulgent. But the imagination is also the faculty that has enabled scientists to bring new knowledge to light and to invent technology that has made us immeasurably more effective.

Compassion is a practically acquired knowledge, like dancing. You must do it and practice diligently day by day.

Today we often think that before we start living a religious life we have first to accept the creedal doctrines and that before one can have any comprehension of the loyalty and trust of faith, one must first force one's mind to accept a host of incomprehensible doctrines. But this is to put the cart before the horse.

A theology should be like poetry, which takes us to the end of what words and thoughts can do.

The hajj is one of the five essential practices of Islam; when they make the pilgrimage to Mecca, Muslims ritually act out the central principles of their faith.

Ever since the Crusades, when Christians from western Europe were fighting holy wars against Muslims in the near east, western people have often perceived Islam as a violent and intolerant faith - even though when this prejudice took root Islam had a better record of tolerance than Christianity.

In the holy city of Mecca, violence of any kind was forbidden. From the moment they left home, pilgrims were not permitted to carry weapons, to swat an insect or speak an angry word, a discipline that introduced them to a new way of living.
