““The diagnostic enterprise hinges on an optimistic notion: that disease is part of a natural world that only awaits our understanding. But even if this is true, nature gives up its secrets grudgingly, and our finite senses are in some ways ill suited to extracting them. More important, our prejudices lead us to tear nature where we want it to break. Science, especially modern medicine, is founded on this equally optimistic idea: that experts can purge their inquiry of prejudice and desire, and map the landscape of suffering along its natural boundaries.””
