Clarity and consistency are not enough: the quest for truth requires humility and effort.

Don’t nurture a sense of guilt; rather, nurture a sense of responsibility married with a sense of humility.

We have to reconcile ourselves with philosophical questions in every field. Every field should be open to inquiry and knowledge.

If we agree to say that those terrorists are indeed Muslim, I have no problem whatsoever to condemn their actions. I won't apologise though, or justify my point of view.

Saying that the origin of the Islamic State (IS) is within the Muslim Brotherhood organisation only strengthens IS.

The strength of democratic societies relies on their capacity to know how to stand firm against extremism while respecting justice in the means used to fight terrorism.

Stand up for your values, be courageous and humble
