“Religious belief is without reason and without dignity, and its record is near-universally dreadful.”

“It is my hope and my belief that you will be able to report that I died with dignity, without animal fear and without bravado. I owe that much to myself.”

“It's hard for me, a Jew, to stay in the moment. Without the past, where is the guilt? And without the future, where is the dread? And without guilt and dread, who am I?”

“Just as the dignity of man is based on his freedom--to the extent that he may even say no to God--likewise, the dignity of a science is based on that unconditional freedom which guarantees its independent search for truth. And just as human freedom must include the freedom to say no, so the freedom of scientific investigation must face the risk that its results will turn out to contradict religious beliefs and convictions. Only a scientist who is ready to fight militantly for such an autonomy of thought may triumphantly live to see how the results of his research eventually fit, without contradictions, in the truths of his belief.”

“Faith isn't absence of doubt. It's belief without proof, not without question.”

“Belief is nearly the whole of the universe whether based on truth or not.”
