Schizophrenia affects about one out of two hundred people. It’s a serious mental disorder that typically involves distortions in perception, especially vivid auditory hallucinations, and bizarre and usually paranoid delusion. Imagine trying to carry on a conversation with while at the same time you're surrounded by four other people, talking loudly to you, often about thoughts you might have considered to be private. That’s an exercise support groups often use to suggest to family what it's like to be a schizophrenic.
What is it
To be human, philosophers have often said, is to be rational. But many people, for biological reasons, are clearly not rational. Schizophrenia is not only a malady, it is also a window on how the human mind works, and what it means to be human. Ken and John examine schizophrenia and its lessons for philosophers with John Campbell from UC Berkeley, author of Reference and Consciousness.
