The world has progressed to the point where it's most powerful force is public opinion. And I believe that in this world it is not the great book or epic play, as once was the case, that will shape that opinion, but those who understand mass media and the techniques of mass persuasion...We must not just believe in what we sell. We must sell what we believe in. And we must pour a vast energy into those causes.

In advertising, not to be different is virtually suicidal.

In this very real world, good doesn't drive out evil. Evil doesn't drive out good. But the energetic displaces the passive.

Logic and over-analysis can immobilise and sterilize an idea. It's like love. The more you analyse it, the more it disappears.

There are a lot of great technicians in advertising. And unfortunately they talk the best game. They know all the rules. They can tell you that people in an ad will get you greater readership. They can tell you that a sentence should be this short or that long. They can tell you that body copy should be broken up for easier reading. They can give you fact after fact after fact. They are the scientists of advertising. But there's one little rub. Advertising is fundamentally persuasion and persuasion happens to be not a science, but an art.

Our job is to sell our clients' merchandise... not ourselves. Our job is to kill the cleverness that makes us shine instead of the product. Our job is to simplify, to tear away the unrelated, to pluck out the weeds that are smothering the product message.

You cannot sell a man who isn't listening; word of mouth is the best medium of all; and dullness won't sell your product, but neither will irrelevant brilliance.
