Plutarch's practical essay teaching how to tell a genuine friend from a flatterer who imitates friendship's pleasures without its honesty.
Quomodo Adulator ab Amico Internoscatur ("How to Tell a Flatterer from a Friend") is one of Plutarch's ethical essays in the Moralia, addressed to Antiochus Philopappus. Plutarch opens from self-love: because everyone is naturally biased toward himself, everyone is vulnerable to flattery, which exploits that blind spot the way a lover is blinded about the beloved. The flatterer therefore counts as an enemy of the Delphic maxim "know thyself," since his whole business is to keep a person ignorant of his real faults and worth.
The bulk of the essay is a practical field guide. Plutarch works through the ways flattery counterfeits genuine friendship: in professed fondness and eagerness for company, in imitating a friend's tastes and opinions, in offering exaggerated praise, in performing sympathy for a friend's misfortunes (even pretending to share ailments like poor eyesight, as Dionysius's flatterers did), and in disguising self-interest as generosity, contrasting the flatterer's showy gifts with the Spartans' modest but sincerely meant grain-relief to Smyrna. He draws on stock anecdotes - Solon and Croesus, Antony and Cleopatra's circle, the painter's boys who mock a man once he reveals ignorance - to show how flattery flourishes around power and reputation but evaporates the moment fortune changes, like lice leaving a cooling corpse.
The essay closes on frank speech (parrhesia) as the true friend's chief tool and flattery's opposite: criticism delivered with tact, timing, and enough self-implication that it does not humiliate. Plutarch compares the skilled admonisher to a surgeon or sculptor who cuts or chips but then soothes and finishes the wound rather than walking away. The work matters as a piece of applied moral psychology for people in positions of power - patrons, rulers, the wealthy - who are structurally surrounded by flatterers and need a method, not just a warning, for distinguishing real loyalty from performance.

It is a practical essay in Plutarch's Moralia, addressed to Antiochus Philopappus, that teaches readers to distinguish sincere friendship from flattery. Plutarch shows how flatterers imitate a friend's company, praise, tastes, and even feigned sympathy, and explains why frank, well-timed criticism is the real test of a genuine friend.
Because everyone is already biased in his own favor, Plutarch argues, a person cannot judge himself fairly - the flatterer simply exploits that existing blind spot rather than creating a new one, the same way a lover is blinded about the person he loves.
Plutarch compares flatterers to lice that abandon a body once its blood cools: flatterers attach themselves to reputation, wealth, and power, but disappear the instant a person's fortunes decline, showing their attachment was never to the person himself.
He compares skillful admonition to a surgeon who cuts but then soothes the wound, or a sculptor who chips a statue and then smooths it - frank speech should be honest and timed well, then followed by conversation that eases the sting rather than a friend simply walking away.
He cites the Spartans sending grain to the starving Smyrnaeans, a gift made meaningful because the Spartans genuinely went without food themselves to give it, unlike a flatterer's showy but self-serving generosity.
