La vertu n’irait pas si loin si la vanité ne lui tenait compagnie

Virtue would not go so far if vanity did not keep it company.

Il est difficile de parler de soi longtemps sans vanité.

Anyone who does not see the vanity of the world is very vain himself. So who does not see it, apart from young people whose lives are all noise, diversions, and thoughts for the future?
But take away their diversion and you will see them bored to extinction. Then they feel their nullity without recognizing it, for nothing could be more wretched than to be intolerably depressed as soon as one is reduced to introspection with no means of diversion.

All sensible people know that vanity is the most devastating, the most universal, and the most ineradicable of the passions that afflict the soul of man, and it is only vanity that makes him deny its power. It is more consuming than love. With advancing years, mercifully, you can snap your fingers at the terror and the servitude of love, but age cannot free you from the thraldom of vanity. Time can assuage the pangs of love, but only death can still the anguish of wounded vanity. Love is simple and seeks no subterfuge, but vanity cozens you with a hundred disguises. It is part and parcel of every virtue: it is mainspring of courage and the strength of ambition; it gives constancy to the lover and endurance to the stoic; it adds fuel to the fire of the artist's desire for fame and is at once the support and the compensation of the honest man's integrity; it leers even cynically in the humility of the saint. You cannot escape it, and should you take pains to guard against it, it will make use of those very pains to trip you up. You are defenseless against its onslaught because you know not on what unprotected side it will attack you. Sincerity cannot protect you from its snare nor humour from its mockery.

Yes, vanity is a weakness indeed. But pride - where there is a real superiority of mind, pride will be always under good regulation.

The vanity of the contents” of individual experience is scrutable as an inessential trapping drawn into a matter by vested interests “…since it is at the same time the vanity of the self that knows itself to be vain

It is difficult for a man to speak long of himself without vanity.

Virtue has need of limits.

...vanity is content with the appearance alone

The vanity of others runs counter to our taste only when it runs counter to our vanity.

Human vanity is so constituted that it stiffens before difficulties. The more an object conceals itself from our eyes, the greater the effort we make to seize it, because it pricks our pride, it excites our curiosity and it appears interesting. In fighting for his God everyone, in fact, fights only for the interest of his own vanity, which, of all the passions produced bye the mal-organization of society, is the quickest to take offense, and the most capable of committing the greatest follies.

If we ever admit our shortcomings it is through vanity

You may be sure of appearing as good, safe, stay-at-home wife material, and he will have the utmost respect for you, as he would for a faithful cook, but he’ll not respect you for the one most important asset every woman who has the wherewithal to employ it — you looks! Vanity not only keeps a woman young, but also gives her something to live for, and if you get saddled to a man who stifles this basic female urge, yet ogles its effects in other women, he could well be knocking years off your life.
