Surrealism lives, intensely and magnificently, having found and perfected an effective method of knowledge. (Suzanne Cesaire, "Surrealism and Us")

Such an interesting claim, this. Surrealism has perfected an effective method of knowledge. Its counter-realism, counter-rationality is effective because it subverts the design of "knowledge" as we know it. But does it also help acquire a knowledge. And what is this knowledge. Is this scum-knowledge?
