I feel like this passage from Crime and Punishment says more about politics than about romance.
There’s nothing in the world more difficult than candor, and nothing easier than flattery. If there is only the hundredth part of a false note in candor, there is immediately a dissonance, and then—scandal. But with flattery, even if everything is false down to the last little note, it is still agreeable and is listened to not without pleasure; crude though the pleasure may be, it is still a pleasure. And however crude the flattery may be, at least half of it is sure to seem true. from Crime and Punishment by Fyodor Dostoevsky
