"Just because you're beautiful and perfect, it's made you conceited."
— William Goldman (The Princess Bride)

"If a man thinks he is not conceited, he is very conceited indeed."
— C. S. Lewis

"Why did you come in to-night with your heads in the air? 'Make way, we are coming! Give us every right and don't you dare breathe a word before us. Pay us every sort of respect, such as no one's ever heard of, and we shall treat you worse than the lowest lackey!' They strive for justice, they stand on their rights, and yet they've slandered him like infidels in their article. We demand, we don't ask, and you will get no gratitude from us, because you are acting for the satisfaction of your own conscience! Queer sort of reasoning!... He has not borrowed money from you, he doesn't owe you anything, so what are you reckoning on, if not his gratitude? So how can you repudiate it? Lunatics! They regard society as savage and inhuman, because it cries shame on the seduced girl; but if you think society inhuman, you must think that the girl suffers from the censure of society, and if she does, how is it you expose her to society in the newspapers and expect her not to suffer? Lunatics! Vain creatures! They don't believe in God, they don't believe in Christ! Why, you are so eaten up with pride and vanity that you'll end by eating up one another, that's what I prophesy. Isn't that topsy-turvydom, isn't it infamy?"
— Fyodor Dostoevsky (The Idiot)

"Till swollen with cunning, of a self-conceit,
His waxen wings did mount above his reach,
And, melting, Heavens conspir'd his overthrow.
"
— Christoper Marlowe (The Tragical History of Dr. Faustus)
