Reader of the New York Times are being treated to a five-part series on anosognosia — the condition of having some severe neurological impairment but not knowing that you have it.
Some of the literature on anosognosia is astonishing. You can be paralyzed without knowing you are paralyzed. You can even be blind without knowing you are blind. (Your brain “makes up” a visual field for you. You keep falling over things, of course, but you can’t fathom why.)
I mention this only to bask in the glory of having been the first person to mention anosognosia on The Corner, two years ago.
