Agree, and based on Einstein's own words Jeanne Bryner is actually saying there that Einstein could have believed in something he himself described as the "incarnation of the most childish superstitions"
which doesn't make sense to me .. only thing i can think of is that she could be a Christian herself, so that could then have arisen from an inner temptation to give salve to her own belief .. but, really i have no clue how she could justify saying that "Yes and no, it seems."
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
