I feel sorry for Ray. What a childhood! I am about the same age as Gary; I was a full-blown hippy, lived in the bush, went to Woodstock, attended all of the rock concerts at the Fillmore in NY, marched in all the right protests, and so on.
But I progressed out of that childish mind-set and moved on into practical life and became a research scientist. Unfortunate for Gary, he is locked into that philosophical professorial mind-set and is not allowed to think away from that group think. I hope that Ray is able to progress past that way of life and stay independent.
I think that Gary has done as well as he could with Ray under the circumstances. I am now reading In Search of Bobby Fischer to see the differences.
