The 21st century - and the atheists - needs the presence of religion, just as religion must deal with the real challenges and the thinkers of the day in order to sharpen the conscience and the intelligence of those who study the timeless sacred texts in a spirit of responding to the questions of their time.
Because ethics is fundamentally about questioning the ends, the goals and aims of our actions, we must come back to the rules and ask why. So we must return to the philosophy of law, the raison d'etre and the point of what we're asked to do. It's not easy, it's very demanding and it needs intellectual courage.
I look to Islamic ethics to find something that can provide the basis for shared values with other traditions, and ultimately universal values. This ties into the point I made in a book, 'The Quest for Meaning', that the only way for values to be universal is if they are shared universal values. My main point is, in this quest for value the aim is not to express your distinctness from others, but about being able to contribute to the discussion of universal value.
Very often when I see people who are perceived to be, or who call themselves progressives, sometimes I see an imbalance. Yes I understand the courage in their mind but I don't see the spirituality in their heart, good you are questioning the limits, but what about yourself, are you also liberating yourself?
Freedom of expression is not absolute. Countries have laws that define the framework for exercising this right and which, for instance, condemn racist language.
