I'm disappointed that Carrier hasn't written a parallel exposé about Bertie. Bertrand Russell wasn't a real atheist in his old age. He was clearly over the hill by then—probably senile. He was being manipulated by a young Turk by the name of Antony Flew.
Don't be bamboozled into thinking that Russell wrote those tired old rants against Christianity. They were ghostwritten by Flew—maybe with a helping hand from Ayer.
