Sense in Common

Common sense is a sound judgment not based on specialized knowledge, says the ■American Heritage Dictionary. A translation of Latin sēnsus commūnis, the phrase was to mean common feelings of humanity, they say.

Let us see how Thomas Paine used the phrase “common sense”. The author emphasized, he studiously avoided every thing which was personal. Compliments as well as censure to individuals were not to make any part thereof
“In the following pages I offer nothing more than simple facts, plain arguments, and common sense.
As much hath been said of the advantages of reconciliation, which, like an agreeable dream, hath passed away and left us as where we were, it is but right, that we should examine the contrary side of the argument, and inquire into some of the many material injuries which these colonies sustain, and always will sustain, by being connected with, and dependant on Great Britain. To examine that connexion and dependance, on the principles of nature and common sense, to see what we have to trust to, if separated, and what we are to expect, if dependant.
Common sense will tell us, that the power which hath endeavoured to subdue us, is of all others, the most improper to defend us.”

To sum up specifically on the above, you obviously do not refer for common sense anywhere outside own head.

More, Thomas Paine was not seeking feelings in common with the British.
“As a long and violent abuse of power, is generally the means of calling the right of it in question (…) and as the King of England hath undertaken in his own Right, to support the Parliament in what he calls Theirs… “

Should Thomas Paine’s Common Sense have been about “common feelings of humanity”, there would have had to be more than one human species. The British yet remain people too, though feelings on American and British sides at that time could be pictured with the ■Battleship portal up-to-date.

Was there maybe faith in “common feelings of humanity” in ancient Rome, where the Latin comes from? Ancient Roman military may have been extolled in film industry, yet it is common lore that you make movies to make money. History and human experience is unable to promote the ancient Roman type of human for a pleasurable experience. Roman control over territories was taken through war. Conquered lands were under military policing, and if short of own manpower, the ancient speakers of Latin turned to local control hierarchies to keep up a regime.

There was no faith in “common feelings of humanity” in ancient Rome.

The dictionary by Facciolati, Forcellini, and Bailey gathers on the Latin sensus, ■Google Books Free Resource.
Sensuum alii sunt externi, alii interni; illi sunt quinque: visus, auditus, olfactus, gustus, tactus; hi duo: sensus communis, et phantasia sive imaginatio, ad quam pertinet memoria.

In other words, already the ancients perceived exteroceptive and and interoceptive senses. Those “external” senses were five, to regard impressions that come from outside the body: vision, hearing, smell, taste, and touch.

Those inner were two. The “imagine-making or representative power”, and the common sense that emerged with all senses coming together. Ancients noted that their memories were able to connect to both.

■Lucretius had the common sense arising in the body. ■De rerum natura:
corpus enim per se communis dedicat esse sensus.

Ancient definitions do not say we need to be plain or simple, to be common sense, but modern definitions would keep the common sense apart from education.
Common sense is a basic ability to perceive, understand, and judge things, which is shared by (“common to”) nearly all people and can reasonably be expected of nearly all people without any need for debate, says ■Wikipedia. For the bit of dictator flair, I reckon they must have been off debate for a baker who never specialized, and wondered how to get good bread.
