Humor is the fourth dimension of this world, without it futile and unlivable . . .
A secret conquered at the cost of long suffering, humor is the answer to superior minds to this world in which they feel themselves alien. More than a natural secretion, as it has too often been regarded, humor manifests, on the contrary, the heroic attitude of those who are unwilling to compromise.
— Maurice Nadeau, The History of Surrealism
