In the line of “A theory of Justice”, any human society has an unknown element of fairness embedded deep into the reptile brain 
Am I talking about the weird sexual habits of some humans? No…
Something more basic- something that every human can achieve…
You know about stupidity- but usually (not necessarily), stupidity goes along with ignorance.
Stupidity and ignorance are probably the most democratic features of human societies: anybody can achieve them, no background checking, wealth, inheritance, social status bar any human from being stupid or ignorant 
and the more ignorant somebody is, the less (s)he believes to be
fascinating 
moreover, the more ignorant you are, the more you need to keep pestering everybody on details that you know
what do I know? that no matter how many languages I will learn, how many books I will read and how many documents and studies I will research and keep ghost-writing, how many places I will visit.
the more I learn, the more that simple, essential, aesthetically supreme two-word sentence will stand true: “scio nescire”- I know that I do not know
when you learn something, remember that maybe sharing that knowledge with everybody you meet could be irrelevant to the on-going communication
PS you wordsmiths out there: I know that there are few typos here and there, but I hate the spelling checkers
