everything which fools a good man is perfectly incapable of any other attitude to anything than that of a dishonourable liar, an absolute liar, but none the less an innocent liar, a blue-eyed liar, a virtuous liar.

Context

“it would be asking them to do what people have been forbidden to ask them to do, to open their eyes to their own selves, and to learn to distinguish between "true" and "false" in their own selves. The dishonest lie alone suits them: everything which fools a good man is perfectly incapable of any other attitude to anything than that of a dishonourable liar, an absolute liar, but none the less an innocent liar, a blue-eyed liar, a virtuous liar. These "good men," they are all now tainted with morality through and through, and as far as honour is concerned they are disgraced and corrupted for all eternity. Which of them could stand a further truth "about man"?” source
