“There are two things in the world that can never get on together—religion and common sense. Religion deals with the next life, common sense with this; religion points to the sky, common sense to the earth; religion is all imagination, common sense all reason; religion deals with what nobody can understand, common sense with what everybody can understand; religion gives us no return for our investments but flash notes on the bank of expectation, common sense gives us good interest and full security for our capital. They are as opposite as two things can possibly be, and they are always at strife. Religion is always trying to fill the world with delusions, and common sense is always trying to drive them away. Religion says Live for the next world, and common sense says Live for this.”

De la sagesse (1601)
Context: All Religions have this in common, that they are an outrage to common sense for they are pieced together out of a variety of elements, some of which seem so unworthy, sordid and at odds with man’s reason, that any strong and vigorous intelligence laughs at them; but others are so noble, illustrious, miraculous, and mysterious that the intellect can make no sense of them and finds them unpalatable. The human intellect is only capable of tackling mediocre subjects: it disdains petty subjects, and is startled by large ones. There is no reason to be surprised if it finds any religion hard to accept at first, for all are deficient in the mediocre and the commonplace, nor that it should require skill to induce belief. For the strong intellect laughs at religion, while the weak and superstitious mind marvels at it but is easily scandalized by it.

Sunni Hadith
Context: It is narrated on the authority of 'Abdullah b. Umar that the Messenger of Allah observed: O womenfolk, you should give charity and ask much forgiveness for I saw you in bulk amongst the dwellers of Hell. A wise lady among them said: Why is it, Messenger of Allah, that our folk is in bulk in Hell? Upon this the Holy Prophet observed: You curse too much and are ungrateful to your spouses. I have seen none lacking in common sense and failing in religion but (at the same time) robbing the wisdom of the wise, besides you. Upon this the woman remarked: What is wrong with our common sense and with religion? He (the Holy Prophet) observed: Your lack of common sense (can be well judged from the fact) that the evidence of two women is equal to one man, that is a proof of the lack of common sense, and you spend some nights (and days) in which you do not offer prayer and in the month of Ramadan (during the days) you do not observe fast, that is a failing in religion. This hadith has been narrated on the authority of Abu Tahir with this chain of transmitters.

The Fabric of Reality (1997)

Free Culture (2004)
Context: A simple idea blinds us, and under the cover of darkness, much happens that most of us would reject if any of us looked. So uncritically do we accept the idea of property in ideas that we don't even notice how monstrous it is to deny ideas to a people who are dying without them. So uncritically do we accept the idea of property in culture that we don't even question when the control of that property removes our ability, as a people, to develop our culture democratically. Blindness becomes our common sense. And the challenge for anyone who would reclaim the right to cultivate our culture is to find a way to make this common sense open its eyes.
So far, common sense sleeps. There is no revolt. Common sense does not yet see what there could be to revolt about.
