““Finally, some of the genes identified in certain variants of schizophrenia or bipolar disease actually augment certain abilities. If the most pathological variant of a mental illness can be sifted out or discriminated from the high-functioning variants by genes or gene combinations alone, then we can hope for such a test. But it is much more likely that such a test will have inherent limits: most of the genes that cause disease in one circumstance might be the very genes that cause hyperfunctional creativity in another. As Edvard Munch put it, "[My troubles] are part of me and my art. They are indistinguishable from me, and [treatment] would destroy my art. I want to keep those sufferings." These very "sufferings," we might remind ourselves, were responsible for one of the most iconic images of the twentieth century-of a man so immersed in a psychotic era that he could only scream a psychotic response to it.””
