Most of the paragraphs in this Jonathan Derbyshire FT article are excellent, here is one of them:
Sokolsky-Tifft recalls Parfit quoting a line from Homer in the middle of a talk. “He started to weep because he found it so beautiful. That was when I first started to get the idea that this was a man with a strange heart, for whom art was always bubbling beneath the surface of these logical arguments.”
Parfit attributed his obsession with a handful of places — he once said that there were only 10 things in the world he wanted to photograph — to a condition called aphantasia, the inability to form mental images. He was unable to visualise things familiar to him, even his wife’s face when they weren’t together.
Recommended, the work is first-rate, as is the article, and subscribe to the FT if you must.
