I have often thought that one of the less attractive traits of various professional bodies and institutions is the deeply ingrained suspicion and outright hostility which can exist towards anything unorthodox or unconventional.

The medieval Islamic world, from Central Asia to the shores of the Atlantic, was a world where scholars and men of learning flourished. But because we have tended to see Islam as the enemy of the West, as an alien culture, society, and system of belief, we have tended to ignore or erase its great relevance to our own history.

Conflict, of course, comes about because of the misuse of power and the clash of ideals, not to mention the inflammatory activities of unscrupulous and bigoted leaders. But it also arises, tragically, from an inability to understand and from the powerful emotions which, out of misunderstanding, lead to distrust and fear.

I think I can safely say that, as adolescents, most people have excess energy to spare and need adventure, excitement, and a challenge.
