“No, the menace of the supernatural is that it attacks where modern minds are weakest, where we have abandoned our protective armor of superstition and have no substitute defense.”

“Are we at last brought to such humiliating and debasing degradation that we cannot be trusted with arms for our defense? Where is the difference between having our arms in possession and under our direction, and having them under the management of Congress? If our defense be the real object of having those arms, in whose hands can they be trusted with more propriety, or equal safety to us, as in our own hands?”

“Like in the animal kingdom, where every creature has its defenses and weapons, humans also possess powerful instruments for camouflage, defense and attack.”

“The old restriction meant that only the orthodox were allowed to discuss religion. Modern liberty means that nobody is allowed to discuss it. Good taste, the last and vilest of human superstitions, has succeeded in silencing us where all the rest have failed.”

“Where we have reasons for what we believe, we have no need of faith; where we have no reasons, we have lost both our connection to the world and to one another.”

“We may be sure that the characteristic blindness of the twentieth century - the blindness about which posterity will ask, "But how could they have thought that?" - lies where we have never suspected it... None of us can fully escape this blindness, but we shall certainly increase it, and weaken our guard against it, if we read only modern books. Where they are true they will give us truths which we half knew already. Where they are false they will aggravate the error with which we are already dangerously ill. The only palliative is to keep the clean sea breeze of the centuries blowing through our minds, and this can be done only by reading old books.”
