I'm calling BS on this statement, because common sense is anything but common, and there are a lot of idiots out there whose reason is flawed.....and their perception of reality and truth is dependent on their close-minded, ethnocentric, sexist, bigoted, cultural monism.Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense.
Common sense, by its "commonality", is not a privatized affair. It involves "public" matters, "public" concerns, and democratic rationality.
