The series is a work of love. I always feel so privileged when I read one of the Durants' works. This particular volume was first published in the year I was born. And yet, the Durants make me feel as if they are the world's best dinner guests. Erudite, warm, and witty. I'm in good company with my praise. It seems the Asimovs were also fans. http://www.jamierubin.net/2014/05/09/isaac-asimov-on-will-durants-story-of-civilization/
