Just finished watching a discussion between Richard Dawkins and Lawrence Krauss. There were many profound things said, and many obvious ones that unfortunately still need to be said, but this quote particular gave me a good laugh.

In regards to theology not being a real subject, I put this challenge out to all theologians. Name me one piece of knowledge theology has contributed to human society in the last 500 years. When I speak to theologians, they always seem to answer “well, what do you mean by knowledge?”, but when I talk to chemists, physicists and medical doctors, they give me concrete facts straight away.

– Lawrence Krauss.
