Common human understanding which, as mere sound (not yet cultivated) understanding, is looked upon as the least we can expect from anyone claiming the name of a human being, has therefore the doubtful honour of having the name of common sense (sensus communis) bestowed upon it; and bestowed, too, in an acceptation of the word common (not merely in our own language, where it actually has a double meaning, but also in many others) which makes it amount to what is vulgar what is everywhere to be met with a quality which by no means confers credit or distinction upon its possessor.
