Stephan:   You have probably heard about this New York Times interview; it has certainly caused a  storm of commentary. I have sat on it for a couple of days just thinking about it, because when I read it I found it so alarming I wasn't quite sure how to process it. Commentators are describing it as a sign of the onset of dementia, or mental illness. I'm not a psychiatrist so will not presume a psychiatrist's skills. But even as a layman it is obvious something is deeply wrong.  It isn't just the multiple lies and misstatements; that's the new norm, as weird as that sounds. It is is also the internal self-contradictions, and the incoherence of Trump's thinking. More than anything it reminded me of the kind of rants I heard on mental wards when, as a teenager, I volunteered to read to patients at Longview State Hospital. I think we are in dangerous and uncharted waters.
