"And here is the point, about myself and my co-thinkers. Our belief is not a belief. Our principles are not a faith. We do not rely solely upon science and reason, because these are necessary rather than sufficient factors, but we distrust anything that contradicts science or outrages reason. We may differ on many things, but what we respect is free inquiry, openmindedness, and the pursuit of ideas for their own sake."

"It is illogical to say, as many etatists do, that liberalism is hostile to or hates the state, because it is opposed to the transfer of the ownership of railroads or cotton mills to the state. If a man says that sulphuric acid does not make a good hand lotion, he is not expressing hostility to sulphuric acid as such; he is simply giving his opinion concerning the limitations of its use."

"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."
