: Actually, you're kinda right :) Let me copy-paste... and translate:
It starts with: "La puissance de bien juger, de distinguer le vrai d'avec le faux, qui est proprement ce qu'on nomme le bon sens, ou la raison, est naturellement égale en tous les hommes." -> "Power is to be able to judge, to distinguish true from false, which is what one properly calls common sense or reason, and it is naturally equal among all men."
So here's he states equality of common sense... which is what i was saying, BUT... then he writes this:
"Le bon sens est la chose au monde la mieux partagée : car chacun pense en être bien pourvu." -> "Common sense is the most well spread thing in the world: everyone thinks he has enough."
which is precisely what you said :)
So in the end, common sense turns out to be a super relative thing. And any dumbass still is sure to hold enough to make sound decisions.
Which brings us back to Florian's issue: yes, there must be enough morons on G+ already to report accounts instead of just blocking them.
