"Don't you believe in flying saucers, they ask me? Don't you believe in telepathy? - in ancient astronauts? - in the Bermuda triangle? - in life after death?No, I reply. No, no, no, no, and again no.One person recently, goaded into desperation by the litany of unrelieved negation, burst out "Don't you believe in anything?"Yes", I said. "I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be."

Therefore, let us explain as often as possible, and particularly at the departure of life, that we base our faith on firm foundations, on Truth for putting into action our ideas which do not depend on fables and ideas which Science has long ago proven to be false."

What a tragedy just to pass through and get nothing out of it."
