Truth does not demand belief. Scientists do not join hands every Sunday, singing, "Yes, gravity is real! I will have faith! I will be strong! I believe in my heart that what goes up, up, up must come down. Amen!"

If they did, we would think they were pretty insecure about it.

— Dan Barker








Experience without theory is blind, but theory without experience is mere intellectual play. ~ Immanuel Kant
