Just saw this today on eSkeptic:

My confidence in venturing into science lies in my basic belief that as in science so in Buddhism, understanding the nature of reality is pursued by means of critical investigation: if scientific analysis were conclusively to demonstrate certain claims in Buddhism to be false, then we must accept the findings of science and abandon those claims.

– His Holiness the Dalai Lama from his book The Universe in a Single Atom

Gotta love that quote. I have great respect for that man.
