Orwell, George — Nineteen eighty-four [774]

In our society, those who have the best knowledge of what is happening are also those who are furthest from seeing the world as it is. In general, the greater the understanding, the greater the delusion: the more intelligent, the less sane. — Orwell, George, Nineteen eighty-four, 774

Note

A compressed paradox stated almost epigrammatically — knowledge and delusion rise together, and the triadic sentence builds to the bluntest possible formulation.
