It goes unnoted in the article, but you could probably get an entire second piece out of the phrase "...defending themselves against the formidable blessing of offspring."

At the time it was written, Einstein had three children (though his first child's story is basically unknown, and she was either adopted or died in infancy). He was also divorced from their mother, with whom both his sons lived, but corresponded with them throughout their lives. I'd be rather interested to see an ambivalent comment like "formidable blessing" put in the context of these relationships.
