In Defense of Common Sense - New York Times

It is gratifying, to see in print, an opinion that one has long held, even if it is merely an editorial, namely that the common mans common sense is worthwile, not only in day-to-day life, but in science as well. The unfortunate effect of denigrating common sense, has been to denigrate common people's opinions and observations. Only scientists are qualified to pass judgements on such things, they would tell you. Of course, there are many things that run contrary to common sense, but that is no reason to throw the baby out with the bath water.
