"The Demon Haunted World" by Carl Sagan.
Very few books have the power to change the way you perceive the world, this one certainly does.
Sagan tilts against the windmills of ignorance and pseudoscience with a clear eye and devastating logic.
The following quote relating to claims of miracles at Lourdes sums up his approach admirably.
"The spontaneous remission rates of all cancers lumped together, is estimated to be one in ten thousand and one in a hundred thousand. If no more than 5% of those who come to Lourdes were there to treat their cancers, there should have been something between 50-100 "miraculous" cures of cancer alone. Since only 3 of the attested 65 cures are of cancer, the rate of spontaneous remission at Lourdes seems to be lower than if the victims had just stayed at home.
Of course if you are one of the 65 it is going to be be very hard to convince you that your trip to Lourdes wasn't the cause of the remission of your disease.
Post Hoc, ergo propter hoc>"
