One point of difference between Eastern philosophies and the "Big 3"

From Zen and the Art of Motorcycle Maintenance:

"...the doctrinal differences among Hinduism and Buddhism and Taoism are not anywhere near as important as doctrinal differences among Christianity and Islam and Judaism. Holy wars are not fought over them because verbalized statements about reality are never presumed to be reality itself."

Interesting point. When you're not dead-set (no pun intended) on proving that your view of reality's the "right" one, there's a lot less to fight about.
