The need for sociability induce man to be in touch with his fellow men. However, this need might not ("ne saurait", Fr.) find its full (or complete) satisfaction in the conventional (or superficial, - "conventionnel", Fr.) and deceitful world, in which (or where) everyone is mainly (or mostly) trying to assert oneself in front of others ("devant les autres", Fr.), to appear, and hoping to find in society ("mondaine", Fr.) relationships some advantages for his interest and vanity (or vainglory or conceit", Fr).
I found during the course of my political career on the national scene there's a point where the vanity burns away and you've had your fill of your name in the papers, or big adoring crowds, or the exercise of power. And for me that happened fairly quickly. And then you are really focused on: What am I going to get done with this strange privilege that's been granted to me? How do I make myself worthy of it?
He who denies his own vanity usually possesses it in so brutal a form that he instinctively shuts his eyes to avoid the necessity of despising himself.
For some natures, changing their opinions is just as much a requirement of cleanliness as changing their clothes: for others, however, it is merely a requirement of vanity.
