About the time the West discovered Aristotle's Ethics and Politics in the twelfth century, Islam had reached it's peak. The top imams at the time decided that Islam would no longer use the elements of philosophy which had been their strong suit for 500 years. So in began their decline when they rejected all that they had been able to glean from the Greek philosophers.
The West then took all that the Greek civilization had and entered into the Renaissance with rather amazing results. The West left the Muslims in the dust.
So, when Pope Benedict spoke at Regensburg and got lambasted by the muslims, he was only trying to invite them back to the dialogue they dismissed in the 12th century.
The problem is that when there is no dialogue there is no chance for understanding and no chance to fix any problems.
There has been some recent activity on the willingness of Islamic philosophers willing to enter into dialogue and actually meeting with philosophers of other faiths. Let's pray that these meetings are fruitful.
