I , of course never met him, but having listened to him speak, and read much, if not most, of his printed output, I believe Ray's estimate of him that he was Autistic to some degree was right.
He was not of course a Rhodes scholar, his command of languages was limited, especially of the ancient languages of the Bible, and all his beliefs were coloured by his contact with other W.T believers.
Because he was unable to really relate to people, and empathise with them, he was ideal as someone who could serve as an "Oracle" for the W.T, he would say in life, and in print, what he felt was best for the advancement of the W.T.
He cared not, or rather to be fair, was incapable of caring, what terrible effects his doctrines and pronouncements had on the lives of the average J.W.
Probably more to be pitied than denigrated, he was one of life's mis-fits.
But he did have a baleful effect on the lives of so many, mine included.
