"In practical talk, a mans common sense means his good judgement, his freedom from eccentricity, his gumption."

"Many quite nefarious ideologies pass for common sense. For decades of American history, it was common sense in some quarters for white people to own slaves and for women not to vote. ... If common sense sometimes preserves the social status quo, and that status quo sometimes treats unjust social hierarchies as natural, it makes good sense on such occasions to find ways of challenging common sense."

"Science and common sense differ as cultivated fruits differ from wild fruits. Science sows its seeds of inquiry, and gathers the fruit. Common sense picks the fruit, such as it, is by the wayside. Common sense has no fields or orchards of knowledge."

"The phrase is self-contradictory; "sense" is never "common"."

"Le bon sens est la chose du monde la mieux partagée; car chacun pense en être si bien pourvu, que ceux même qui sont les plus difficiles à contenter en toute autre chose nont point coutume den désirer plus quils en ont."

"Consider the very roots of our ability to discern truth. Above all (or perhaps I should say "underneath all"), common sense is what we depend on – that crazily elusive, ubiquitous faculty we all have to some degree or other.... If we apply common sense to itself over and over again, we wind up building a skyscraper. The ground floor of the structure is the ordinary common sense we all have, and the rules for building news floors are implicit in the ground floor itself. However, working it all out is a gigantic task, and the result is a structure that transcends mere common sense."
