"A Scout is a friend to all," reads the Scout Law. "He is a brother to other Scouts. He offers his friendship to people of all races, religions and nations, and respects them even if their beliefs and customs are different from his own."

How important is friendship? Aristotle, a founder of Western philosophy and one of the most important shapers of modern thought, devoted two books to it in his massive 10-book study of ethics.

In its highest form, Aristotle wrote, true friendship is mankind's most important relationship. We might be friendly toward others merely for pleasure, or for some mutual benefit. But the ultimate friendship Aristotle valued so highly is the type in which each person not only is good themselves, but wishes and creates good for others.

That's the essence of being friendly in Scouting. Being a good Scout -- or a good person -- is not just about doing a good turn. It's about being good, to yourself and to those around you.
