Obligatory current favourite quotes:

"Religion is regarded by the common people as true, by the wise as
false, and by the rulers as useful".
 -- Seneca
"I have more confidence in the methods of science, based on the amazing
record of science and its ability over the centuries to answer
unanswerable questions, than I do in the methods of faith (what are they?)."
 -- David J. Gross "Physics Nobel Laureate"

"Atheism is a religion to the same extent that not collecting stamps is a
 hobby."
