An “apple polisher” is one who gives gifts to win friendship or special treatment. It is not exactly
a bribe(贿赂), but is close to it.
All sorts of people are apple polishers, including politicians and people in high offices-just abou
t everybody. Oliver Cromwell, the great English leader, offered many gifts to win the support of
George Fox and his party, but failed.
There are other phrases meaning the same thing as “apple-polishing”-“soft-soaping” or
“buttering-up”. A gift is just one way to “soft-soap” somebody, or to “butter him up”. Another
that is just as effective is flattery, giving someone high praise-telling him how good he looks, or how
well he speaks, or how talented and wise he is.
Endless are the ways of flattery. Who does not love to hear it? Only an unusual man can resist the
thrill of being told how wonderful he is. In truth, flattery is good medicine for most of us, who get so
little of it.
We need it to be more sure of ourselves. It cannot hurt unless we get carried away by it. But if we
just lap it up for its food value and nourishment, as a cat laps up milk, then we can still remain true to
ourselves.
Sometimes, however, flattery will get you nothing from one who has had too much of it. A good
example is the famous 12th century legend of King Canute of Denmark and England. The king got
tired of listening to endless sickening flattery of his courtiers(朝臣). They overpraised him to the skies,
as a man of limitless might.
He decided to teach them a lesson. He took them to the seashore and sat down. Then he ordered
the waves to stop coming in. The tide was too busy to listen to him. The king was satisfied. This might
show his followers how weak his power was and how empty their flattery.
