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

It is very often nothing but our own vanity that deceives us. Women fancy admiration means more than it does.
And men take care that they should.

Women may be vain, but when a man is vain, it is beyond believing, for a man is willing to die for his vanity.

If human nature were not base, but thoroughly honourable, we should in every debate have no other aim than the discovery of truth; we should not in the least care whether the truth proved to be in favour of the opinion which we had begun by expressing, or of the opinion of our adversary. That we should regard as a matter of no moment, or, at any rate, of very secondary consequence; but, as things are, it is the main concern. Our innate vanity, which is particularly sensitive in reference to our intellectual powers, will not suffer us to allow that our first position was wrong and our adversary’s right. The way out of this difficulty would be simply to take the trouble always to form a correct judgment. For this a man would have to think before he spoke. But, with most men, innate vanity is accompanied by loquacity and innate dishonesty. They speak before they think; and even though they may afterwards perceive that they are wrong, and that what they assert is false, they want it to seem thecontrary. The interest in truth, which may be presumed to have been their only motive when they stated the proposition alleged to be true, now gives way to the interests of vanity: and so, for the sake of vanity, what is true must seem false, and what is false must seem true.

Some men, by dint of excessive egotism, manage to persuade their contemporaries that they are very great men indeed: they publish their acquirements so loudly in people’s ears, and keep up their own praises so incessantly, that the world’s applause is actually taken by storm.

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.

A person may be proud without being vain. Pride relates more to our opinion of ourselves, vanity to what we would have others think of us.

A man must have a good deal of vanity who believes, and a good deal of boldness who affirms, that all the doctrines he holds are true, and all he rejects are false.

Man is the vainest of all
creatures that have their being upon earth. As long as heaven
vouchsafes him health and strength, he thinks that he shall come to
no harm hereafter, and even when the blessed gods bring sorrow upon
him, he bears it as he needs must, and makes the best of it; for
God Almighty gives men their daily minds day by day. I know all
about it, for I was a rich man once, and did much wrong in the
stubbornness of my pride, and in the confidence that my father and
my brothers would support me; therefore let a man fear God in all
things always, and take the good that heaven may see fit to send
him without vainglory.

No one is more arrogant toward women, more aggressive or scornful, than the man who is anxious about his virility.

If we ever admit our shortcomings it is through vanity

To tell you the truth - mind, this is strictly between ourselves, please; I shouldn't like your wife to know I said it - the women folk don't understand these things; but between you and me, you know, I think it does a man good to swear.

Never worry about what you say to a man. They’re so conceited that they never believe you mean it if it’s unflattering.

There are instances, indeed, wherein men shew a vanity in resembling a great man in his countenance, shape, air, or other minute circumstances, that contribute not in any degree to his reputation; but it must be confess’d, that this extends not very far, nor is of any considerable moment in these affections. For this I assign the following reason. We can never have a vanity of resembling in trifles any person, unless he be possess’d of very shining qualities, which give us a respect and veneration for him. These qualities, then, are, properly speaking, the causes of our vanity, by means of their relation to ourselves. Now after what manner are they related to ourselves? They are parts of the person we value, and consequently connected with these trifles; which are also suppos’d to be parts of him. These trifles are connected with the resembling qualities in us; and these qualities in us, being parts, are connected with the whole; and by that means form a chain of several links betwixt ourselves and the shining qualities of the person we resemble. But besides that this multitude of relations must weaken the connexion; ’tis evident the mind, in passing from the shining qualities to the trivial ones, must by that contrast the better perceive the minuteness of the latter, and be in some measure asham’d of the comparison and resemblance.
